When we multiply our servings by a given amount, we're not multiplying our cost of cake by the same amount. This tells us that this is not proportional. One way to think about proportional relationships, we already said, that the ratio between the variables will be equivalent.

Which is the correct first step in finding the height of a cylinder with a volume of 178 pi cubic inches and a radius of 8 inche

Elis [28]

Answer:

LAST OPTION: $178 \pi=\pi (8)^2h$

Step-by-step explanation:

For this exercise you need to remember that the volume of a cylinder can be calculated with the following formula:

$V=\pi r^2h$

Where "r" is the radius and "h" is the height of the cylinder.

In this case, you know that the height of this cylinder and its volume are the following:

$V=178 \pi\ in^3\\\\r=8\ in$

Knowing these values you can substitute them into the formula shown above:

$178 \pi=\pi (8)^2h$ (CORRECT FIRST STEP)

Now you can solve for "h" by dividing both sides of the equation by $\pi (8)^2$ . Therefore, you get:

$\frac{178 \pi}{\pi (8)^2}=\frac{\pi (8)^2h}{\pi (8)^2}\\\\h=2.78\ in$

The second box is weak positive , strong positive , weak negative , strong negative , & no

nikdorinn [45]

To check for the correlation, simply look at both the age and the cost values, since as age increases the cost decreases, there is a negative trend, since the cost is decreasing as one increases.

The actual amount can be approximated, because the amount is not going down as quickly it goes down slowly it would probably be -0.05.

This is a weak negative.
