Answer:

B. (30 + 13)^2

Step-by-step explanation:

(B) is correct because you have to add 30 and 13 first so they need to be in the parentheses and then you have "raise the sum to the 2nd power" which in signal form it would be "^" so after you add 30 and 13 you get 43^2 then all you have to do is 43 times 43.

Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th
Naya [18.7K]

Answer:

39.25 cubic feet of paint will be needed by Ellis.

Step-by-step explanation:

Volume of a cylinder:

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

V = \pi r^2h = 3.14r^2h

How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?

This is the combined volume of these 10 fenceposts.

They are each 5 feet tall and have a diameter of 1 foot.

Radius is half the diameter, so r = \frac{1}{2} = 0.5. Also h = 5

10 fenceposts:

Each has the same volume, so:

V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25

39.25 cubic feet of paint will be needed by Ellis.

Pls Help me with this answer
snow_lady [41]

Answer:

a. 5

b. -3

Step-by-step explanation:

a. (5*(8^1/3 + 27^1/3)^3)^1/4

= ((40^1/3 + 135^1/3)^3)^1/4

≈ ((3.42 + 5.13)^3)^1/4

≈ (8.55^3)^1/4

≈ 625^4

= 5

b. 64^-1/3*(64^1/3 - 64^2/3)

= 0.25*(4 - 16)

= 1/4 or 0.25 *-12

= -12*1 / 4

= -12/4

= -3

Hope this helped :3
