If the radius of the right cylinder is 5 in and the radius of the oblique cylinder is 4 in, they will have the same volume as lo

steposvetlana [31]

Answer:

False

Step-by-step explanation:

The volume of a right cylinder is given by the formula:

$V=\pi r^2h$

And the volume if a oblique cylinder is also given by the formula:

$V=\pi r^2h$

Regardless of the height, if the radius are different, then the volume would not be the same.

Algebraically:

$\pi(4)^2h\neq\pi(5)^2h\\16\pi\neq25\pi$

Sound policy requires that a certain number of trees be planted for every tree that is cut down for example of 8 trees are cut d

Nimfa-mama [501]

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted

A video game has 25 levels. At level one, a player has 5 points. Each additional level increases the player's points by 10. If

ozzi

Answer:

B. (3,25)

Step-by-step explanation:

x = level of the video game

y = number of points

At level 1, a player has 5 points.

At level 2, the player has 5 + 10 = 15 points

Therefore, we can use the function notation this way:

f(x) = 5x + 10

The only ordered pair given that is from this function is:

B. (3,25)

f(3) = 5 * 3 + 10

f(3) = 15 + 10 = 25

The remaining three don't represent this function.
