The answer to A. is 108cm or 1.08m

First convert 2m to cm:
2m x 100 = 200 cm
Next convert 6m to cm:
6m x 100 = 600 cm
Divide the height of the person by his/her shadow:
200cm ÷ 600cm = <span>0.33333333333 = .3</span>
Multiply 360cm by .3:
360cm x .3 = 108cm
108cm ÷ 100 = 1.08m

The answer to B. is 6.8 cm.

The scale seems a bit small... are you sure you don't mean 0.8 m?
a = length of actual car.
8.5 x 0.8 = 1 x a
6.8 = 1 x a
6.8 ÷ 1 = a
6.8 = a

If you did mean 0.8 m... the answer is 680 cm or 6.8 m.

a = length of actual car.
0.8m x 100 = 80cm
8.5 x 80 = 1 x a
680 = 1 x a
680 ÷ 1 = a
680 = a
680 ÷ 100 = 6.8

I need a step by step explanation on how you solved the equation.

Ghella [55]

Answer: x=3 and y=−2

Step-by-step explanation:

x=−2y−1;4x−4y=20

Step: Solve x=−2y−1 for x:

Step: Substitute−2y−1 for x in 4x−4y=20:

4x−4y=20

4(−2y−1)−4y=20

−12y−4=20(Simplify both sides of the equation)

−12y−4+4=20+4(Add 4 to both sides)

−12y=24

−12y

−12

(Divide both sides by -12)

y=−2

Step: Substitute−2 for y x=−2y−1:

x=−2y−1

x=(−2)(−2)−1

x=3(Simplify both sides of the equation)

aniked [119]

Answer:

ROA = 7.77 percent

Step-by-step explanation:

Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million

Thus, profit = 5.6% of $13.6 million

profit = 5.6 / 100 * $13.6 million = $0.7616 million

Profit is same as net income

Formula for ROA (return on asset) = net income/ total asset

total asset as given = $9.8 million

Thus, ROA = $0.7616/ $9.8 = 0.0777

ROA in percentage = 0.0777*100 = 7.77

Thus, ROA is 7.77 percent .
