---- = -----------

x         6+x

Using cross products

8(6+x) = 11x

Distribute

48 +8x = 11x

Subtract 8x from each side

Using the volume of a cylinder, it is found that the approximate height of the container in inches is given by:

d. 15.48

The volume of a cylinder of radius r and height h is given by:

[tex]V = \pi r^2h[/tex]

In this problem, Sam pours 3 gallons of water into a cylindrical container, and it will be 90% full. Hence, the volume, in cubic feet, is:

[tex]0.9V = \frac{3}{7.48}[/tex]

[tex]V = \frac{3}{0.9(7.48)}[/tex]

[tex]V = 0.4456[/tex]

The diameter of the container is 8 inches, hence the radius is of 4 inches = 0.3333 feet, considering a feet has 12 inches.

The height, in feet, will be given by:

[tex]V = \pi r^2h[/tex]

[tex]0.4456 = (0.3333)^2\pih[/tex]

[tex]h = \frac{0.4456}{(0.3333)^2\pi}[/tex]

[tex]h = 1.2768[/tex]

Considering a feet has 12 inches, in inches, the height will be of:

1.2768 x 12 = 15.48

Hence option D is correct.

168 children and 35 adults swam in the public pool

Let the number of children in the pool be x

Let the number of adult in the pool be y

If  203 people used the public swimming pool, then;

x + y = 203

Also,  if the daily prices are $1.75 for children and $2.25 for adults with the receipts for admission totaled $372.75, then;

1.75x + 2.25y = 372.75

175x + 225y = 37275

7x + 9y = 1,491

Substitute equation 1 into 2

7(203-y) + 9y = 1,491

1421- 7y + 9y = 1491

2y = 70

y = 35

Since x = 203 - y

x = 203 - 35

x = 168

Hence 168 children and 35 adults swam in the public pool

Answer:

15 dollars

Step-by-step explanation:

Since a shirt is an unknown cost, and the pants costs 18 dollars, they costed 33 dollars overall.

In order to find the shirt price, let's subtract the price of the jeans from the total price.

33-18=15

The shirt's price is 15 dollars.

Answer:

$15

Step-by-step explanation:

$33- total cost

-$18- pants cost

=$15 for the shirt cost

In other words 33-18=x

                            15=x

x being the cost of the shirt!

The average rate of change, of the function, between the intervals, x = 2 to x = 6 is: 180.

Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex].

Given the function, [tex]f(x)= 3^x + 25[/tex],

The average rate of change using the intervals of, x = 2 to x = 6 would be solved as shown below:

a = 2

b = 6

f(a) = [tex]f(2)= 3^2 + 25[/tex] = 34

f(b) = [tex]f(6)= 3^6 + 25[/tex] = 754

Average rate of change = [tex]\frac{754 - 34}{6 - 2} = \frac{720}{4}[/tex]

Average rate of change = 180

Answer:

4,400 :)

Step-by-step explanation:

Answer and Step-by-step explanation:

Anytime that you are rounding a number, there is a rule that you should follow:

"Anything 1 - 4 is closest to the number before, or the lower side. Anything 5 - 9 is closest to the higher side of whatever round you are trying to get to."

If that doesn't make sense, let me explain.

In this case, we need to look at the hundreds placement, which is the 3 in this situation. But we can't look at that, because then we would be rounding to the nearest thousand.

(Important:) So, we need to look at the number behind it, which is 8. Eight is on the higher side of 5 - 9, which means that it grants us permission to round to the next hundred.

The is: 4,400.
