600=total

Then..multiply 120 by 3 which will give the 3/5 boys which is 360 so...

Jesse earns $12.62 an hour, plus she earns overtime for hours exceeding 40 hours per week. What is her gross weekly pay for work

vladimir2022 [97]

The correct answer is c) $637.31

12.62 x 40 = 504.8

time and a half is the amount you get paid + half the amount you get paid

so half of 12.62 is 6.31 + 12.62 = 18.93

18.93 x 7 = 132.51

504.8 + 132.51 = 637.31

In the above triangle, if x = , y = 1, and z = 2, then which of the following is equal to tan(60°)?

vesna_86 [32]

Answer: Option A

$tan(60\°) = \sqrt{3}$

Step-by-step explanation:

We know the sides and z. So since it is a straight triangle we use the Pythagorean theorem to pull the length of the x side.

$z ^ 2 = x ^ 2 + y ^ 2\\\\x^2 = z^2 - y^2\\\\x=\sqrt{z^2 - y^2}\\\\x=\sqrt{2^2 - 1^2}\\\\x=\sqrt{4 - 1}\\\\x=\sqrt{3}$

By definition, the tangent of an angle is:

$tan(\theta) = \frac{opposite}{adjacent}$

In this case:

$adjacent = y=1\\\\opposite=x =\sqrt{3}\\\\\theta=60\°$

Then:

$tan(60\°) = \frac{\sqrt{3}}{1}$

$tan(60\°) = \sqrt{3}$

Step-by-step explanation:

its this answer because to find point slope form you have to do y1 - y2 and in the coordinate provided, -3 is y so y- (-3) or y+3 hope this helped ^u^
