Two hikers are 33 miles apart and walking towards each other. They meet in 10 hours. Find the rate of each Hiker if one joker walks 1.1 mph fast than the other
Answer:
Step-by-step explanation:
Let x represent the rate of the first hiker.
if one hiker walks 1.1 mph fast than the other, it means that the rate of the second hiker would be x + 1.1
Two hikers are 33 miles apart and walking towards each other. They meet in 10 hours. This means that in 10 hours, both hikers travelled a total distance of 33 miles.
Distance = speed × time
Distance covered by the first hiker in 10 hours would be
x × 10 = 10x
Distance covered by the second hiker in 10 hours would be
10(x + 1.1) = 10x + 11
Since the total distance covered by both hikers is 33 miles, then
10x + 10x + 11 = 33
20x + 11 = 33
20x = 33 - 11 = 22
x = 22/20 = 1.1 miles per hour
The rate of the second hiker would be
1.1 + 1.1 = 2.2 miles per hour.
the sum of three consecutive number is 114. what is the smallest of the three numbers?
Answer:
37
Step-by-step explanation:
37+38+39
Answer: the smallest of the three numbers is 37
Step-by-step explanation:
Let x represent the smallest number.
Since the three numbers are consecutive, it means that the next number would be x + 1
Also, the last and also the largest number would be x + 2
If the sum of the three consecutive numbers is 114, it means that
x + x + 1 + x + 2 = 114
3x + 3 = 114
Subtracting 3 from the Left hand side and the right hand side of the equation, it becomes
3x + 3 - 3 = 114 - 3
3x = 111
Dividing the Left hand side and the right hand side of the equation by 3, it becomes
3x/3 = 111/3
x = 37
At a corner gas station, the revenue R varies directly with the number g of gallons of gasoline sold. If the revenue is $56.40 when the number of gallons sold is 12, find a linear equation that relates revenue R to the number g of gallons of gasoline. Then find the revenue R when the number of gallons of gasoline sold is 7.5.
Answer:
(i) R = 4.70g
(ii) R = $35.25
Step-by-step explanation:
(i) R ∞ g
Removing the proportionality symbol, we have
R = kg, where k is the constant of proportion
56.40 = k(12)
Divide both sides by 12
56.40/12 = k(12)/12
$4.70 = k
k = $4.70
So, R = 4.70g (which is the linear equation relating Revenue, R to number of gallons, g)
(ii) When g = 7.5,
R = 4.70 * 7.5 = 35.25
R = $35.25
The revenue R at a gas station varies directly with the number of gallons of gasoline sold g. The linear equation relating R to g is R = 4.7g. The revenue when the number of gallons sold is 7.5 is $35.25.
Explanation:
In this particular scenario, we're dealing with a problem of direct variation. In a direct variation, as one quantity increases, the other increases proportionally. This can be represented by a linear equation of the form y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of variation (the ratio of y to x).
Here, the Revenue (R) varies directly with the number of gallons of gasoline sold (g). We can calculate the constant of variation (k) by dividing the given Revenue (R) by the given number of gallons (g): k = 56.4 ÷ 12 = 4.7. So, the linear equation relating R to g is: R = 4.7g.
To find the revenue R when the number of gallons of gasoline sold is 7.5, substitute g = 7.5 into the equation: R = 4.7 * 7.5 = $35.25

To find the equation of a line, we need the slope of the line and a point on the line. Since we are requested to find the equation of the tangent line at the point (4, 2), we know that (4, 2) is a point on the line. So we just need to find its slope. The slope of a tangent line to f(x) at x = a can be found using the formula

[tex]f(x)=\sqrt x[/tex] and x=4
Step-by-step explanation:
We are given that a curve
[tex]y=\sqrt x[/tex]
We have to find the equation of tangent at point (4,2) on the given curve.
Let y=f(x)
Differentiate w.r.t x
[tex]f'(x)=\frac{dy}{dx}=\frac{1}{2\sqrt x}[/tex]
By using the formula [tex]\frac{d(\sqrt x)}{dx}=\frac{1}{2\sqrt x}[/tex]
Substitute x=4
Slope of tangent
[tex]m=f'(x)=\frac{1}{2\sqrt 4}=\frac{1}{2\times 2}=\frac{1}{4}[/tex]
In given question
[tex]m=\lim_{x\rightarrow a}\frac{f(x)-f(a)}{x-a}[/tex]
[tex]\frac{1}{4}=\lim_{x\rightarrow 4}\frac{f(x)-f(4)}{x-4}[/tex]
By comparing we get a=4
Point-slope form
[tex]y-y_1=m(x-x_1)[/tex]
Using the formula
The equation of tangent at point (4,2)
[tex]y-2=\frac{1}{4}(x-4)[/tex]
[tex]4y-8=x-4[/tex]
[tex]x-4y-4+8=0[/tex]
[tex]x-4y+4=0[/tex]
The equation of the tangent line of a function at a particular point can be found by using the formula y - y1 = m(x - x1), where the slope m is the derivative of the function at the specific point. In this case, find the derivative at x = 4 and substitute into the formula along with the point (4,2).
Explanation:To find the equation of the tangent line of a function at a particular point, we can indeed utilise the slope-point form of a straight line equation, which is y - y1 = m (x - x1). In this case the point on the line is (4,2).
However regarding the slope, it is calculated as the derivative of the function f(x) at the point x = a.
Let us assume the function f(x). The derivative f '(x), also known as the slope of the tangent line at any point x, is found by taking the derivative of f(x). So to find the slope at x = 4, you would calculate f '(4).
Substitute the value of the derivative at the point (4,2) which represents our m(slope), x1=4 and y1=2 into the linear equation y - y1 = m(x - x1) to generate the equation of the tangent line.

Answer: 72 adult tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of senior tickets that were sold.
A theatre sold a total of 98 adult and senior tickets. It means that
x + y = 98
x = 98 - y - - - - - - - - - - - - -1
Adult tickets sold for 12$ each and senior tickets sold for 8$ each bringing in a total of 1,072$. This means that
12x + 8y = 1072 - - - - - - - - - - - 2
Substituting equation 1 into equation 2, it becomes
12(98 - y) + 8y = 1072
1176 - 12y + 8y = 1072
- 12y + 8y = 1072 - 1176
- 4y = - 104
y = - 104/ - 4
y = 26
Substituting y = 26 into equation 1, it becomes

Melanie bought bags of colored sand that each cost the same. She spent a total of $24. Find three possible costs per bag and the number of bags that she could have purchased
Answer:
Step-by-step explanation:
Factors of 24 are 1,2,3,4,6,8,12,24
Since we are looking for prices as well as quantity, these numbers must go in pairs.
1*24 = option 1
2*12 = option 2
3*8 = option 3

6 * -7 = 42 and 6 - 7 = -1 so the factors are:
(x - 7)x + 6).
The factor form of the expression x² - x - 42 is (x - 7)(x + 6).
To factor the expression x² - x - 42, we need to find two binomial factors that, when multiplied together, give us the original expression.
We can start by looking for two numbers that multiply to -42 and add up to -1, which is the coefficient of the x term in the expression.
The pair of numbers that satisfy these conditions are -7 and 6.
If we multiply these two numbers, we get -42, and if we add them, we get -1.
Therefore, we can write the expression as:
x² - x - 42
= (x - 7)(x + 6)
This means that the original expression can be factored as the product of two binomials: (x - 7) and (x + 6).

35/12 + 4/3 = (35 + 16)/12 = 51/12
The number of cartons left would be
5 - 51/12 = (60 - 51)/12 = 9/12
Since a carton has 12 eggs,
9/12 carton will have 9/12 × 12 = 9 eggs
Follow the steps above, and find c, the total of the payments related to financing, and the monthly payment. A customer buys an automobile from you, the salesman. The price of the car, which includes taxes and license, amounts to $5,955.00. The customer wants to finance the car over 48 months after making a $500 down payment. You inform him that the true annual interest rate is 18%.
the monthly payment is approximately $163.06 and the total payments related to financing are approximately $7834.88.
To find the monthly payment and the total payments related to financing, we need to follow these steps:
1. Calculate the total amount financed.
2. Use the total amount financed to calculate the monthly payment using the formula for monthly payments on a fixed-rate loan.
3. Multiply the monthly payment by the number of months to find the total payments related to financing.
Given:
- Price of the car = $5955.00
- Down payment = $500.00
- Finance period = 48 months
- Annual interest rate [tex]\(= 18\%\)[/tex]
Step 1: Calculate the total amount financed.
The total amount financed is the difference between the price of the car and the down payment.
[tex]\[ \text{Total amount financed} = \text{Price of the car} - \text{Down payment} \][/tex]
[tex]\[ \text{Total amount financed} = \$5955.00 - \$500.00 \][/tex]
[tex]\[ \text{Total amount financed} = \$5455.00 \][/tex]
Step 2: Calculate the monthly payment.
To calculate the monthly payment, we use the formula for the monthly payment on a fixed-rate loan:
[tex]\[ M = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1} \][/tex]
Where:
- M is the monthly payment
- P is the principal amount (total amount financed)
- r is the monthly interest rate (annual interest rate divided by 12)
- n is the number of payments (finance period in months)
First, we need to convert the annual interest rate to a monthly interest rate:
[tex]\[ r = \frac{18\%}{12} = 0.18 \times \frac{1}{12} = 0.015 \][/tex]
Now, we plug in the values:
[tex]\[ M = \frac{5455 \times 0.015 \times (1 + 0.015)^{48}}{(1 + 0.015)^{48} - 1} \][/tex]
[tex]\[ M ≈ \frac{5455 \times 0.015 \times (1.015)^{48}}{(1.015)^{48} - 1} \][/tex]
Using a calculator, we find that the monthly payment M is approximately $163.06.
Step 3: Calculate the total payments related to financing.
[tex]\[ \text{Total payments} = \text{Monthly payment} \times \text{Number of months} \][/tex]
[tex]\[ \text{Total payments} = \$163.06 \times 48 \][/tex]
[tex]\[ \text{Total payments} ≈ \$7834.88 \][/tex]
So, the monthly payment is approximately $163.06 and the total payments related to financing are approximately $7834.88.
Finally, the arena decides to offer advertising space on the jerseys of the arena’s own amateur volley ball team. The arena wants the probability of being shortlisted to be 0.14. What is this as a percentage and a fraction? What is the probability of not being shortlisted?
Give your answer as a decimal. Those shortlisted are entered into a final game of chance. There are six balls in a bag (2 blue balls, 2 green balls and 2 golden balls). To win, a company needs to take out two golden balls. The first ball is not replaced.
What is the probability of any company winning advertising space on their volley ball team jerseys?
Answer: 7/50
14%
1/30
Step-by-step explanation:0.14 to fraction =0.14/100=14/100=7/50
0.14 to %= 0.14 ×100=14%
Total number of balls=6
Blue balls=2
Golden balls=2
Green balls=2
Probability of picking the first ball=1/6
Probability of picking the second ball= 1/5
P(winning wit 2 golden balls)=1/6×1/5=1/30
The probability of any company winning advertising space on their volleyball team jerseys is approximately 0.0093, or 0.93%.
Probability of Being Shortlisted
The probability of being shortlisted is given as 0.14.
As a Percentage:[tex]\[ 0.14 \times 100 = 14\% \][/tex]
As a Fraction:[tex]\[ 0.14 = \frac{14}{100} = \frac{7}{50} \][/tex]
Probability of Not Being Shortlisted:The probability of not being shortlisted is:
[tex]\[ 1 - 0.14 = 0.86 \][/tex]
Probability of Winning Advertising Space
To win the advertising space, a company needs to draw two golden balls consecutively without replacement from a bag containing 6 balls (2 blue, 2 green, and 2 golden).
Total Balls:There are 6 balls in total.
First Draw:The probability of drawing a golden ball first:
[tex]\[ \frac{2}{6} = \frac{1}{3} \][/tex]
Second Draw:After drawing one golden ball, there are 5 balls left, including 1 golden ball:
The probability of drawing a golden ball second:
[tex]\[ \frac{1}{5} \][/tex]
Combined Probability:The probability of drawing two golden balls consecutively is the product of the individual probabilities:
[tex]\[ \frac{1}{3} \times \frac{1}{5} = \frac{1}{15} \][/tex]
Final Probability of Winning Advertising Space
Since the company needs to be shortlisted first and then draw the two golden balls to win the advertising space, the combined probability is:[tex]\[0.14 \times \frac{1}{15}\][/tex]
Convert 0.14 to a fraction:[tex]\[0.14 = \frac{7}{50}\][/tex]
Multiply the probabilities:[tex]\[\frac{7}{50} \times \frac{1}{15} = \frac{7}{750}\][/tex]
Convert to a decimal:[tex]\[\frac{7}{750} \approx 0.0093\][/tex]
Jill found a new fruit punch recipe that calls for orange juice and lemon-lime soda. If orange juice costs $3.60 per bottle and lemon-lime soda costs $1.80 per bottle and the recipe calls for 3 times as many bottles of lemon-lime soda as orange juice, at most how many bottles of orange juice can she buy if she only has $54.00?
Answer:
She can buy at most 6 bottles of orange juice.
Step-by-step explanation:
Consider the provided information.
The recipe calls for 3 times as many bottles of lemon-lime soda as orange juice,
Let she buy x bottles of orange juice.
According to question: Lemon lime soda = 3x
Orange juice costs $3.60 per bottle and lemon-lime soda costs $1.80 per bottle. She only has $54.00
[tex]3.60x+1.80(3x)=54[/tex]
[tex]3.60x+5.4x=54[/tex]
[tex]9x=54[/tex]
[tex]x=6[/tex]
Hence, she can buy at most 6 bottles of orange juice.
Jill can buy at most 6 bottles of orange juice.
Explanation:To find out how many bottles of orange juice Jill can buy, we need to determine the cost of the orange juice and the cost of the lemon-lime soda based on the given prices. Let's assume she can buy 'x' bottles of orange juice. Since the recipe calls for 3 times as many bottles of lemon-lime soda, she can buy 3x bottles of lemon-lime soda. The total cost of the orange juice and the lemon-lime soda must not exceed $54.00.
The cost of the orange juice is $3.60 per bottle, so the cost of 'x' bottles of orange juice is 3.60x dollars. The cost of the lemon-lime soda is $1.80 per bottle, so the cost of 3x bottles of lemon-lime soda is 1.80 * 3x = 5.40x dollars.
To find the maximum number of bottles of orange juice she can buy, we need to solve the inequality:
3.60x + 5.40x ≤ 54.00
Combining like terms, we have:
9.00x ≤ 54.00
Dividing both sides of the inequality by 9.00, we get:
x ≤ 6
Jill can buy at most 6 bottles of orange juice.

The 68-95-99.7 rule tells us how to find the middle 68%, 95% or 99.7% of a normal distribution. suppose we wanted to find numbers a and b so that the middle 80% of a standard normal distribution lies between a and b where a is less than
b. one of the answers below are not true of a and
b. mark the answer that is not true.
Answer:
The values of a and b are -1.28 and 1.28 respectively.
Step-by-step explanation:
It is provided that the area of the standard normal distribution between a and b is 80%.
Also it is provided that a < b.
Let us suppose that a = -z and b = z.
Then the probability statement is
[tex]P (a<Z<b)=0.80\\P(-z<Z<z)=0.80[/tex]
Simplify the probability statement as follows:
[tex]P(-z<Z<z)=0.80\\P(Z<z)-P(Z<-z)=0.80\\P(Z<z)-[1-P(Z<z)]=0.80\\2P(Z<z)-1=0.80\\P(Z<z) = \frac{1.80}{2}\\P(Z<z) =0.90[/tex]
Use the standard normal distribution table to determine the value of z.
Then the value of z for probability 0.90 is 1.28.
Thus, the value of a and b are:
[tex]a = -z = - 1.28\\b = z = 1.28[/tex]
Thus, [tex]P(-1.28<Z<1.28)=0.80[/tex].
If the last digit of weight measurement is equally likely to be any of the digits 0 through 9. Round your answers to one decimal place (e.g. 98.7). What is the probability that the last digit is 0?
Answer:Probability that the last digit is 0=0.1
Step-by-step explanation:
The likely digits for the last digits runs from 0 through 9 giving a total of 10 digits
The fore P(last digit to be 0) = 1/10 = 0.1
If the last digit of a weight measurement rounded to the nearest tenth place is equally likely to be any of the digits from 0 through 9, then the probability that the last digit is 0 is 0.1 or 10%.
Explanation:The question is asking about the probability that the last digit in a weight measurement, rounded to one decimal place, is 0. Given that the last digit is equally likely to be any digits from 0 through 9, this is a basic probability problem with each outcome being equally likely.
Since there are 10 possible results (the digits 0 through 9), and we are interested in only 1 of these results (the digit 0), the probability can be calculated as 1 divided by 10. Therefore, the probability that the last digit is 0 is 0.1 or 10%.
This is a standard concept in an introductory probability course and is a fundamental idea that will be used in more complex probability problems.
