Answer:

275 m^3

Step-by-step explanation:

The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.

First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.

In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.

Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so

V=(1/3)(75/2)*22=275

Answer:

34) A

35) C

36) D

Step-by-step explanation:

34) The perimeter of a triangle is equal to the sum of the lengths of its sides

Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)

Combine like terms (same variables)

(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)

9.6p + 0.4q + 2.2r

Time possibilities

1 hour - $3 - $5 = $-2 No

2 hours - $6 - $5 = $1 Yes

3 hours - $9 - $5 = $4 Yes

4 hours - $12 - $5 = $7 Yes

5 hours - $15 - $5 = $10 Yes

6 hours - $18 - $5 = $13 Yes

7 hours - $21 - $5 = $16 Yes

8 hours - $24 - $5 = $19 No

9 hours - $27 - $5 = $22 No

The possible hours that Ms. Barnes can park are 2 - 7 hours

The only inequality graph that represents all of these values is C
