Number 9 is C. 1,000 ft^3

Number 10 is B. 144 in^3

Step-by-step explanation:

For both number 9 and 10, we are trying to find volume. Volume is the space within a three dimensional shape. To find the volume you do length × width × height. Knowing this we can start solving.

For number 9, the length is 20 ft, the width is 10 ft and the height/depth is 5 ft. Now we multiply these numbers.

20*10*5 = 1,000

This gives of 1,000. Since this is in feet, we add feet/ft at the end. Also since it is volume, you add ^3

1,000 ft^3

Now lets do the same for number 10

The length is 6, the width is 2 and the height is 12. Now multiply

6*2*12 = 144

This one is in inches so we add inches/in at the end. It is also volume so we add ^3 as well

144 in^3

Answer from: Quest

complete the steps to find the area of the trapezoid.

area of rectangle = 256 square units

area of triangle 1 = 24 square units

area of triangle 2 = 16 square units

area of triangle 3 = 96 square units

area of trapezoid = 120 square units

step-by-step explanation:

Answer from: Quest

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

$ab^2+ac^2=bc^2$

$ab^2+ac^2=x^2$ )

triangle abd and cba are similar,

$\frac{ab}{bc}=\frac{bd}{ab}$

$ab^2=bc\cdot bd$

$25=bc\cdot bd$ (2)

triangle cad and cba are similar,

$\frac{ac}{bc}=\frac{cd}{ac}$

$ac^2=bc\cdot dc$

$7\times 7=bc\cdot dc$

$49=bc\cdot dc$ )

using (1), (2) and (3), we get

$25+49=x^2$

$74=x^2$

hence proved.

therefore option 2 is correct.
