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
Answer: D
<u>Step-by-step explanation:</u>
The first matrix contains the coefficients of the x- and y- values for both equations (top row is the top equation and the bottom row is the bottom equation. The second matrix contains what each equation is equal to.
![\begin{array}{c}2x-y\\x-6y\end{array}\qquad \rightarrow \qquad \left[\begin{array}{cc}2&-1\\1&-6\end{array}\right] \\\\\\\begin{array}{c}-6\\13\end{array}\qquad \rightarrow \qquad \left[\begin{array}{c}-6\\13\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bc%7D2x-y%5C%5Cx-6y%5Cend%7Barray%7D%5Cqquad%20%5Crightarrow%20%5Cqquad%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D2%26-1%5C%5C1%26-6%5Cend%7Barray%7D%5Cright%5D%20%5C%5C%5C%5C%5C%5C%5Cbegin%7Barray%7D%7Bc%7D-6%5C%5C13%5Cend%7Barray%7D%5Cqquad%20%5Crightarrow%20%5Cqquad%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D-6%5C%5C13%5Cend%7Barray%7D%5Cright%5D)
The product will result in the solution for the x- and y-values of the system.
