Sally earns 200 dollars for working 10 hours. What is the independent variable

Neporo4naja [7]

A good way to figure out an independent variable is to know what a dependend variable is and its bascially what changes because of the independent variable. So the dependent variable is the $200 because it changes due to the amount of hours Sally worked thus meaning the independent variable would be 10 hours.

stiv31 [10]

Answer:

422 Square Inches

Step-by-step explanation:

6x7=42

7x13=91

6x13=78

(2)42+(2)91+(2)78=422

You are multiplying each calculation by 2 because a rectangular prism has 6 sides. 2 sides height x width, 2 sides height x length, and 2 sides width x length

What is the length of AC ?

Lelechka [254]

Triangles ABC and CDE and similar with ABC being dilated larger. This means we can use ratios to help solve for x, and then solve fo AC.

$\frac{84}{156-x} = \frac{7}{x}$
$\frac{84x}{156-x} = 7$
$84x = 7(156 - x)$
$84x = 1092 - 7x$
$91x = 1092$
$x = 12$
So, from this problem we now know that x is equal to 12. We merely need to plug that into what is given for AC and solve for AC.
AC = 156 - 12
AC = 144
Therefore, A is equal to 144.
