Answer:
.56 miles or 56/100 of a mile
Step-by-step explanation:
5 days = 4/10 = .4
7 days = ?
.4 / 5 * 7 = .56
.56 miles or 56/100 of a mile
Diane walked her dog 4/10 of a mile each day for 5 days. By multiplying the daily distance by the number of days, we determine that Diane walked a total of 2 miles with her dog over the week.
To determine how far Diane walked her dog over the 5 days, we need to calculate the total distance by multiplying the daily distance by the number of days she walked her dog. Diane walked her dog 4/10 of a mile each day for 5 days.
Here's how you can calculate the total distance:
Multiply the daily distance by the number of days.
So, 4/10 mile/day imes 5 days = 2/1 miles.
Therefore, Diane walked a total of 2 miles with her dog over the 5 days.

Skyler is 104 miles away from Marcus. They are traveling towards each other. If Marcus travels 8 mph faster than skyler and they meet after 4 hours, how fast was each traveling?
Speed of skyler is 204 mph and speed of marcus is 212 mph
Solution:
Skyler is 104 miles away from Marcus
Therefore,
Distance = 104 miles
They meet after 4 hours
Time taken = 4 hours
Let "x" be the speed of sklyer
Marcus travels 8 mph faster than skyler
Therefore,
Speed of marcus = 8 + x
They are traveling towards each other
Since they are traveling towards each other, we can add up their speeds
Speed = x + 8 + x = 2x + 8
The distance is given by formula:
[tex]distance = \frac{speed}{time\ taken}\\\\104 = \frac{8+2x}{4}\\\\104 \times 4 = 8 + 2x\\\\8 + 2x = 416\\\\2x = 416-8\\\\2x = 408\\\\x = 204[/tex]
Thus speed of skyler = x = 204 mph
Speed of marcus = 8 + x = 8 + 204 = 212 mph
Thus speed of skyler is 204 mph and speed of marcus is 212 mph

There are two functions that can be used to describe the percent of people 25 years and older who have completed at least high school. For both functions f(x)=0.44x + 87.5 and g(x)=0.008x^2 + 0.42x + 87.5 is the number of years since 2008, and any y (or f(x) or g(x)) is the percent of people 25 and older completing at least high school. Assume that the trend of g(x) continues. Find g(15) and describe in words what this means.
g(15)=
Answer:
[tex]g(15)=93.8\%[/tex]
see the explanation
Step-by-step explanation:
Let
x ----> the number of years since 2008,
g(x) ----> the percent of people 25 years and older who have completed at least high school
we know that
[tex]g(x)=0.008x^2+0.42x+87.5[/tex]
so
For x=15 years since 2008
substitute
[tex]g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%[/tex]
That means
In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%
Final answer:
To find g(15), we substitute x with 15 in the function g(x) = [tex]0.008x^2 + 0.42x + 87.5[/tex], yielding g(15) = 95.6%. This means that in 2023, it's projected that 95.6% of people 25 and older will have completed high school according to the given quadratic trend.
Explanation:
The student is asking for the evaluation of the function g(x) = [tex]0.008x^2[/tex] + 0.42x + 87.5 at x = 15, which represents the number of years since 2008. To find g(15), we need to substitute x with 15 in the given function:
g(15) = 0.008(15)2 + 0.42(15) + 87.5
Calculating the value step by step:
152 = 225
0.008 × 225 = 1.8
0.42 × 15 = 6.3
1.8 + 6.3 + 87.5 = 95.6
Therefore, g(15) = 95.6.
In words, this means that if the trend described by function g(x) continues, then in the year 2023 (15 years after 2008), 95.6% of people aged 25 and older will have completed at least a high school education. This is a projection of graduation rates over time.

The school marching band has a budget of up to $750 to cover 15 new uniforms and
competition fees that total $300. How much can they spend for one uniform?
a.
Write an inequality to represent this situation.
b.
Solve the inequality and describe what it means in the situation.
a. The inequality 15x+300≤750 represents the situation.
b. It means that the band can spend at most $30 on each uniform without exceeding the budget.
Step-by-step explanation:
Given,
Budget = $750
Competition fee = $300
Uniforms to make = 15
Let,
x be the amount for each uniform.
a. Write an inequality to represent this situation.
Uniforms to make * Cost per uniform + Competition ≤ Budget
15x+300 ≤ 750
The inequality 15x+300≤750 represents the situation.
b. Solve the inequality and describe what it means in the situation.
[tex]15x+300\leq 750\\15x+300-300\leq 750-300\\15x\leq 450[/tex]
Dividing both sides by 15
[tex]\frac{15x}{15}\leq \frac{450}{15}\\x\leq 30[/tex]
It means that the band can spend at most $30 on each uniform without exceeding the budget.

The inequality representing this situation is 15x + $300 <= $750. Solving for x gives x <= $30
The student is interested in determining how much the school marching band can spend on each new uniform given a specific budget constraint. To represent this situation, we need to establish an inequality.
Writing the inequality-
Let's denote the cost of one uniform as x. With 15 uniforms needed and competition fees totalling $300, the inequality that represents the budget situation is:
15x + $300 <= $750
Solving the inequality-
To solve for x, subtract $300 from both sides of the inequality:
15x <= $450
Next, divide both sides by 15:
x \<= $30
This means that they can spend at most $30 for each uniform. The inequality tells us the maximum spending cap for one uniform, ensuring the total cost for all uniforms plus competition fees does not exceed the available budget of $750.

How to solve systems using elimination
See explanations below on solving simultaneous equations by elimination.
Step-by-step explanation:
In solving simultaneous equations by elimination, you make one side of the variables equal and eliminate that side by either addition or subtraction, then solve the remaining variable whose value is then used in one of the equations to find the other variable. For example;
(i) 4x - 2y= 10
(ii) x+ y =4
Making the x variable part equal to eliminate x
1(4x-2y=10)--------multiply by 1
4(x+y=4) ---------multiply by 4
4x -2y =10
4x+4y=16
Apply subtraction to eliminate the x variables
0 +6y =6
6y=6
y=6/6 = 1
Use the value of y =1 in the equation x+y= 4
x+y=4
x+1=4
x=4-1 = 3

[tex]KE = \frac{1}{2}mv^{2}[/tex]
where the moving body has m as the mass and v as the velocity.
If m is in Kg and v is in meter/sec, then KE will be expressed in Joule.
