Answer:

352 ft³
1.98 m³
706.9 in³

Step-by-step explanation:

Use the appropriate volume formula, and fill in the given values.

Rectangular prism

V = LWH

V = (8 ft)(11 ft)(4 ft) = 352 ft³

Right triangular prism

V = 1/2(LWH)

V = 1/2(11 m)(9 m)(0.04 m) = 1.98 m³

Cylinder

V = πr²h

V = π(5 in)²(9 in) = 225π in³ ≈ 706.9 in³

_____

Additional comment

We're a little surprised to see the triangular prism has a dimension of 4 cm when the other dimensions are given in meters. 1 cm = 0.01 m.

Answer:

$\boxed {m = -\frac{5}{7}}$

Step-by-step explanation:

Use the Slope Formula to determine the slope of two given points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

First Point: $(x_{1} , y_{1})$

Second Point: $(x_{2}, y_{2})$

-Substitute both points:

First Point: $(5, 11)$

Second Point: $(19, -1)$

$m = \frac{-1 - 11}{19 - 5}$

-Solve for the slope:

$m = \frac{-1 - 11}{19 - 5}$

$m = \frac{-10}{14}$

$\boxed {m = -\frac{5}{7}}$

Therefore, the slope is $-\frac{5}{7}$

Answer:

12 feet.

Step-by-step explanation:

1 inch = 4 feet.

Multiply 3 by 4.

3×4=12

I multiplied 3 by 4 because 1-inch equals 4 feet, which means if we multiply both terms by 3, you will get 3 inch = 12 feet.

Hope this helps!

Peggy was taking a timed 60-question test. She was able to correctly answer 70% of the questions but had to skip the rest. How m

Goryan [66]

The answer should be 42.

Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.

So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.

I hope this helps you forward.
