Answer:

72 cm³

Step-by-step explanation:

We can use the formula for a triangle prism's volume to solve.

V = [tex]\frac{B*H*L}{2}[/tex]

-> B is the base, H is the height, L is the length

-> Think of the area of a triangle. It is the same formula, but we also multiply by the length.

V = [tex]\frac{B*H*L}{2}[/tex]

V = [tex]\frac{3*4*12}{2}[/tex]

V = [tex]\frac{144}{2}[/tex]

V = 72

Answer:

72 cm³

Answer:

I believe your answer would be 1794

Step-by-step explanation:

2600 - 806 = 1794

To check:

1796 (St) + 806 (chairs left) = 2600 (total chairs)

So I would think the answer is 1794

The 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Total seats = 2600

The students left 806 seats vacant.

Number of students(occupied seats = 2600 – 806 = 1794

A percentage of the seats in the theatre were filled by the 6th graders on the trip:

= (1794/2600)×100

= 0.69×100

= 69%

Thus, the 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.

Answer:

68

Step-by-step explanation:

The 22-degree angle plus angle x is equal to the right angle opposite of it. A right angle is equal to 90 degrees. Therefore, we know that 22 + x = 90.

22 + x (- 22) = 90 (- 22)

x = 68

Therefore, angle x equals 68 degrees.
