Divide the volume by the two measures. 728 ÷ 8 = 91 ÷ 6.5 = 14 so, the shoe box is we inches long.

Answer: option 4 x < 175

x/5 < 35

multiply both sides by 5

x < 175

(i can’t do the correct symbol but you get the idea)

A baby pool is shaped like a short, wide cylinder and holds 52 ft3 of water. A medium pool measures 4 times the height and width

timama [110]

Answer:

$D.\ 3328\ ft^3$

Step-by-step explanation:

Given

Volume of baby pool = 52ft³

Required

Determine the volume of the medium pool

Volume of a cylinder is calculated as:

$V = \pi r^2h$

Hence, the volume of the baby pool is:

$\pi r^2h = 52$

where r and h are the radius and height of the baby pool

Represent the height and radius of the medium pool as H and R

From the given parameters in the question

$H = 4 * h$ and $R = 4 * r$

$H = 4 h$ and $R = 4 r$

The volume of the medium cylinder is calculated as

$Volume = \pi R^2H$

Substitute 4h for H and 4r for R

$Volume = \pi (4r)^2(4h)$

Open bracket

$Volume = \pi (4r) * (4r) * (4h)$

$Volume = \pi 16r^2 * (4h)$

$Volume = \pi 16r^2 * 4h$

Collect like terms

$Volume = \pi r^2 * h * 4 * 16$

$Volume = \pi r^2 h * 64$

Recall that $\pi r^2h = 52$

So, the expression becomes

$Volume = 52 * 64$

$Volume = 3328$

Hence, the medium pool can hold $3328ft^3$ of water

Answer: 1; -5

Step-by-step explanation:

For this problem, we are asked to find the slope and y-intercept.

We see that this linear line goes through the y-axis at (0,-5). therefore, our y-intercept is -5.

To find the slope, we would use the formula $m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ . We can use the points (0,-5) and (5,0) since we can clearly see the line goes through these 2 points.

$m=\frac{0-(-5)}{5-0} =\frac{5}{5} =1$

From our formula, we found that the slope is 1.

For the first box, you would fill in 1, the slope. The second box would be -5, the y-intercept.
