Answer:

[tex]y=x/4+30[/tex]

Step-by-step explanation:

Let x be the normal time it takes for her to commute. We know that if she was 30min late, this would had 30 min to the journey. She takes a different route, she can travel four times faster than the normal route.

Therefore the normal time of commute will be 4 times less:

[tex]y=x/4+30[/tex]

This equation states that the commute time will be four times faster and adding the 30min that she is late.

Y is equals to one fourth times x plus thirty, y = 4x + 30.

Given that,

Jorie normally leaves work at 5:00 pm, but she is leaving work 30 minutes late today.

She decides to make up time by taking the toll road instead of side streets. She can travel four times faster by taking the toll road.

We have to determine,

Create an equation in terms of x to represent the number of minutes after 5:00 pm she arrives home from work if she leaves late.

According to the question,

Let x represent the number of minutes her normal commute takes when she leaves on time.

She was 30min late, this would had 30 min to the journey. She takes a different route, she can travel four times faster than the normal route.

Therefore,

The normal time of commute will be 4 times less,

[tex]y = 4x +30\\\\[/tex]

Hence, The commute time will be four times faster and adding the 30min that she is late.

Answer: the length of the smallest side is 11 feet.

the length of the medium side is 27 feet.

the length of the longest side is 28 feet.

Step-by-step explanation:

Let x represent the length of the smallest side.

Let y represent the length of the middle side.

Let z represent the length of the longest side.

The perimeter of a triangular garden is 66 feet. This means that

x + y + z = 66 - - - - - - - - - -1

if the middle length side is 5 feet greater than twice the length of the smallest​ side, it means that

y = 2x + 5

The longest side is 5 feet less than 3 times the length of the smallest side. It means that

z = 3x - 5

Substituting y = 2x + 5 and z = 3x - 5 into equation 1, it becomes

x + 2x + 5 + 3x - 5 = 66

6x = 66

x = 66/6 = 11

y = 2x + 5 = 2 × 11 + 5

y = 27

z = 3x - 5 = 3 × 11 - 5

z = 28

The length of the three sides of the triangular garden is 11 feet, 27 feet, and 28 feet.

The perimeter of a triangle is the sum of the lengths of its three sides. Let's assume the length of the smallest side is x. According to the given information, the middle length side is 5 feet greater than twice the length of the smallest side, so it can be expressed as 2x + 5. The longest side is 5 feet less than 3 times the length of the smallest side, so it can be expressed as 3x - 5.

Now, since the perimeter of the triangle is 66 feet, we can set up the equation:

x + (2x + 5) + (3x - 5) = 66

Simplifying this equation, we get:

6x = 66

Dividing both sides by 6, we get:

x = 11

So the length of the smallest side is 11 feet. The middle length side is 2x + 5 = 2(11) + 5 = 27 feet. The longest side is 3x - 5 = 3(11) - 5 = 28 feet.

Answer: The two options are equal after 20days of daily pay.

Step-by-step explanation:

If it cost $30 to rent a car for a day and $600 to rent the same car for a month(approximately 30days), renting daily is equal to the monthly rentage after 20 days ($30 for 20days which is $30×20 i.e $600)

According to the deduction above, the renting is cheaper daily only for the first 20 days after which the amount equals to the monthly rentage of the same car.

Answer:

20 days.

Step-by-step explanation:

Assume, 1 month = 30 days.

Options:

i. $600 per month

$600/month * 1 month/30 day

= $20 per day.

ii. $30/day.

Renting daily is equal to the monthly rent after 20 days ($30 for 20days which is $30×20 i.e $600)

That is, the renting is cheaper daily only for the first 20 days after which it is equal to the monthly rent.

Answer:

Step-by-step explanation:

1) the figure has 2 hemispheres and 1 cylinder.

2) The formula determining the volume of a hemisphere is expressed as

Volume = 4/3πr³

Where

r represents radius of the hemisphere.

π is a constant whose value is 3.14

The formula determining the volume of a cylinder is expressed as

Volume = 4/3πr³

Where

r represents radius of the cylinder

h represents the height of the cyinder.

3) volume of hemisphere = 4/3 × 3.14 × 2³ = 33.49mm³

Height of cylinder = 10 - (2+2) =6mm

Volume of cylinder = 3.14 × 2²× 6 = 75.36mm³

4) the composite volume is

2 × 33.49 + 75.36 = 142.34mm³

Answer:

A. Increasing cash, which will increase asset turnover

C.Increase assets, which will increase asset turnover and profit margin

Step-by-step explanation:

A reduction in inventory will improve business performance by increasing the efficiency of the company..

return of equity (ROE) can be calculated by: net profit/shareholder equity.

where share holder equity can be calculated by company assets minus debts.

Therefore ROE = Net profit/ (Assets - debts)

With, this formula, it can be deduced mathematically that, increasing ROE will Increase profit gain and  increase asset turnover.

ROE help company to estimate how management is using company assets to actualize profit. Reducing inventory is a reduction in the cost of procurement of goods needed by the company. this eventually increase the cash income of the company.

Also, a reduction in company debts can drastically improve the ROE.

Answer:

Step-by-step explanation:

The total volume of cement in cubic feet to be made is 54 cu ft.

A concrete mixer is in volume proportions of 1 part cement, 2 parts water, 2 parts aggregate, and 3 parts sand. This means that the ratio of the ingredients is

1 : 2 : 2 : 3

Total ratio = 1 + 2 + 2 + 3 = 8

Therefore,

Volume of cement needed would be

1/8 × 54 = 6.75 cubic feet

Volume of water needed would be

2/8 × 54 = 13.5 cubic feet

Volume of aggregate needed would be

2/8 × 54 = 13.5 cubic feet

Volume of sand needed would be

3/8 × 54 = 20.25 cubic feet

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

x = 98 - 26 = 72

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.

Answer:

Amount of ribbon remaining with Lara is [tex]10\frac{1}{3}\ yard[/tex].

Step-by-step explanation:

Given:

Amount of ribbon Lara bought = [tex]8\frac{3}{10} \ yard[/tex]

[tex]8\frac{3}{10} \ yard[/tex] can be Rewritten as [tex]\frac{83}{10}\ yard[/tex]

Amount of ribbon Lara bought = [tex]\frac{83}{10}\ yard[/tex]

Amount of ribbon used to tie a package = [tex]1\frac{2}{5} \ yard[/tex]

[tex]1\frac{2}{5} \ yard[/tex] can be Rewritten as [tex]\frac{7}{5}\ yard[/tex]

Amount of ribbon used to tie a package = [tex]\frac{7}{5}\ yard[/tex]

Amount of ribbon used to make bow= [tex]2\frac{1}{3} \ yard[/tex]

[tex]2\frac{1}{3} \ yard[/tex] can be Rewritten as [tex]\frac{7}{6}\ yard[/tex]

Amount of ribbon used to make bow = [tex]\frac{7}{6}\ yard[/tex]

We need to find the amount of ribbon remaining with Lara.

Solution:

Now we can say that;

Amount of ribbon remaining with Lara can be find by subtracting Amount of ribbon used to tie a package and Amount of ribbon used to make bow from Amount of ribbon Lara bought.

framing in equation form we get;

Amount of ribbon remaining = [tex]\frac{83}{10}-\frac{7}{5}-\frac{7}{6}[/tex]

Now we will make the denominator common using LCM.

LCM of 5,6,10 is 30

So we get;

Amount of ribbon remaining = [tex]\frac{83\times3}{10\times 3}-\frac{7\times6}{5\times6}-\frac{7\times5}{6\times5}=\frac{249}{30}-\frac{42}{30}-\frac{35}{30}[/tex]

Now the denominator are common so we will solve the numerator we get;

Amount of ribbon remaining = [tex]\frac{249-42-35}{30}= \frac{172}{30}[/tex]

Now Given:

Amount of ribbon Joe gave = [tex]4\frac{3}{5}\ yard[/tex]

[tex]4\frac{3}{5}\ yard[/tex] can be rewritten as [tex]\frac{23}{5}\ yard[/tex]

Amount of ribbon Joe gave = [tex]\frac{23}{5}\ yard[/tex]

Now we can say that;

Amount of ribbon remaining with her = [tex]\frac{172}{30}+\frac{23}{5}[/tex]

Now again we will make the denominator common using LCM we get;

Amount of ribbon remaining with her = [tex]\frac{172\times1}{30\times1}+\frac{23\times6}{5\times6} = \frac{172}{30}+\frac{138}{30}[/tex]

Now denominators are common so we will solve the numerators we get;

Amount of ribbon remaining with her = [tex]\frac{172+138}{30}=\frac{310}{30}=\frac{31}{3}\ yard \ \ Or \ \ 10\frac{1}{3}\ yard[/tex]

Hence Amount of ribbon remaining with her is [tex]10\frac{1}{3}\ yard[/tex].

Final answer:

To find out how much ribbon Laura now has, we start with her initial amount, subtract the yardage used in two activities, and add the amount received from Joe, combining fractions and whole numbers to reach the final total yardage.

Explanation:

To calculate the amount of ribbon Laura has after her transactions, we need to perform a few steps involving addition and subtraction of mixed numbers, and then convert that number to a single unit if necessary. Here is how we solve this:

Start with the total ribbon Laura bought: 8 3/10 yards.

Subtract the ribbon used to tie a package: 1 2/5 yards.

Also, subtract the ribbon used to make a bow: 2 1/3 yards.

Add the ribbon given by Joe: 4 3/5 yards.

Combine the fractions and whole numbers separately for precision.

Finally, add or subtract the totals to find out how much ribbon Laura now has.

Let's do the math:

Laura's total ribbon after using some and receiving more from Joe is:

8 3/10 (initial amount) - 1 2/5 (package) - 2 1/3 (bow) + 4 3/5 (from Joe) = Laura's current ribbon amount.
Simplify the fractions and calculate:

Step by step:

Convert mixed numbers to improper fractions or work directly with mixed numbers.

Find common denominators for the fractions.

Add and subtract the fractions.

Add and subtract the whole numbers.

Combine the totals.

We'll end up with a total that represents the yardage of ribbon Laura has left.

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

[tex]sin(theta)=\frac{opposite}{hypotenuse}[/tex]

[tex]sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\[/tex]

a person travel 50 ft from the bottom to the top of the escalator

Using trigonometry, the person travels approximately 50 ft from bottom to top. So, the answer is (a) 50 ft.

To find the distance a person travels from the bottom to the top of the escalator, we can use trigonometric functions. Since the escalator rises at a 30° angle, we can use the sine function to find the vertical component of the distance traveled.

Let's denote the distance traveled from the bottom to the top of the escalator as ( d ).

We know that the vertical component of the distance traveled is [tex]\( d \cdot \sin(30°) \).[/tex]

Given that the height of the second floor is 25 ft, we have:

[tex]\[ d \cdot \sin(30°) = 25 \][/tex]

To find ( d ), divide both sides by ( sin(30°) ):

[tex]\[ d = \frac{25}{\sin(30°)} \][/tex]

Now, let's calculate:

[tex]\[ \sin(30°) \approx 0.5 \][/tex]

So:

[tex]\[ d = \frac{25}{0.5} = 50 \][/tex]

Therefore, the person travels approximately 50 ft from the bottom to the top of the escalator.

So, the correct answer is:

a) 50 ft

Answer:

Step-by-step explanation:

Let x represent the number of batches of soap that Lilth makes.

Let y represent the number of batches of lotion that Lilth makes.

It takes her 20 minutes(20/60 = 1/3 hours) to make a batch of soap and 35 minutes(35/60 = 7/12 hours) to make a batch of lotion. Lilth has 20 hours available to make soap and lotion. This means that

x/3 + 7y/12 = 20

4x + 7y = 240- - - - - - - - - - -1

The cost of producing each batch are $5 for the soap and $15 for the lotion. The materials to make the soap and lotion must cost at most $325. This means that

5x + 15y ≤ 325 - - - - - - - - -2

4x = 240 - 7y

x = (240 - 7y)/4

Substituting

5(240 - 7y)/4 + 15y ≤ 325

(1200 - 35y)/4 + 15y ≤ 325

1200 - 35y + 60y ≤ 1300

25y ≤ 1300 - 1200

25y ≤ 100

y ≤ 100/25

y ≤ 4

4x + 7 × 4 = 240

4x + 28 = 240

4x = 212

x = 212/4 = 53

Therefore, the solution (53, 4) means that she would make at most 53 batches of soap and at most 4 batches of lotion

[tex]0.64\pm (3.29)\sqrt{\dfrac{0.64(1-0.64)}{258}}\\\\\approx 0.64\pm0.0983\\\\=(0.64-0.0983,\ 0.64+0.0983) = (0.5417,\ 0.7383= (54.13\%,\ 53.83\%)[/tex]

Hence, the 99.9% confidence interval for the support level percentage in the entire city is (54.13%, 53.83%) .
