Pythagorean theorem
a^2 + b^2 = c^2
c = longest side
a^2 + 13^2 = 20^2
a^2 + 169 = 400
a^2 = 231, a = squareroot 231

Solution: x = 15.19 cm

Schach [20]

Answer:

181 $\frac{1}{2}$

Step-by-step explanation:

To find how many hours they work per month multiply the amount of hours they work each day by the amount of days they work in a month:

$22 *8\frac{1}{4} = 181\frac{1}{2}$

They work $181\frac{1}{2}$ hours per month.

What is the slope of (-7,-1) and (3,8)? Pls show your work

kondor19780726 [428]

Answer:

$m=\frac{9}{10}$

Step-by-step explanation:

To find the slope between any two points, we can use the following slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let (-7, -1) be (x₁, y₁) and let (3, 8) be (x₂, y₂). Substitute them into the slope formula:

$m=\frac{8-(-1)}{3-(-7)}$

Evaluate:

$m=\frac{9}{10}$

Therefore, the slope between the two points is 9/10.
