Answer:
B
Step-by-step explanation:
<em>Let
be the radius of one sphere.</em>
- Volume of sphere is

Since radius is r, the height of the cylinder will be 
Also, the cylinder has the same radius as the sphere: 
- Volume of Cylinder is

Plugging in the values we get: 
<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:

The ratio is 1:3
Answer choice B is right.
The higher the slope closer it is to being vertical. The lower the slope the closer it is to being horizontal.If the slope is positive Y increases as X increases if the slope is negative Y decreases as X increases.
5.28....What you do is find the hundredth place then locate the number to the right of it. If the number is greater than 4, then you round the hundredth place up a number and if it is less than or equal to 4 then leave the hundredth place alone. but in this case we round it up because 5 is greater than 4 so change 7 to eight.
Answer:
No
Step-by-step explanation:
To solve this problem, plug the given coordinates in for x and y.
If x = -4 and y = 2, the inequality is 4(-4) + 5(2) < -7.
Evaluating 4*-4 and 5*2, the inequality becomes -16 + 10 < -7.
Evaluating -16 + 10, the inequality becomes -6 < -7.
-6 is not less than -7, so (-4, 2) is not a solution of the inequality.
