Geometry question :) could use some help

Step2247 [10]

Answer:

statement A

Step-by-step explanation:

If the ratio

$\frac{QT}{TR}$ = $\frac{QU}{US}$

then TU is parallel to RS

$\frac{QT}{TR}$ = $\frac{32}{36}$ = $\frac{8}{9}$

$\frac{QU}{US }$ = $\frac{40}{45}$ = $\frac{8}{9}$

Since the ratios are equal then line segment TU is parallel to line segment RS

Ac method for x^2+20x-8=0

yanalaym [24]

<h2>Explanation:</h2><h2></h2>

By using quadratic formula:

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\quad a=1,\:b=20,\:c=-8$

$x_{1,\:2}=\frac{-20\pm \sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}$

$x=\frac{-20+\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad 2\left(3\sqrt{3}-5\right)$

$x=\frac{-20-\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad -2\left(5+3\sqrt{3}\right)$

So the solutions are:

$\boxed{x=2\left(3\sqrt{3}-5\right),\:x=-2\left(5+3\sqrt{3}\right)}$

4) Ed earns $12.77 by driving a car for 126

Lunna [17]

Answer:

$.10/hour

Step-by-step explanation:

You need to find whats called a "unit ratio", which is a fancy word for saying anything:1. You would find this by dividing the 2 values together

12.77/126

He would make around $.10

One week, Ashley earned $404.80 at her job when she worked for 22 hours. If she is paid the same hourly wage, how many hours wou

MariettaO [177]

Answer:
20 hours

Explanation:
For this problem, since her hourly rate remains the same, we can set up a proportion to find the amount of hours she worked to make $368.00. The following is how to find the amount of time with proportions:

368.00/404.80 = x / 22
(22 * 368) / 404.80 = x
20 = x

Hence, she would need to work 20 hours to make $368.00.

Cheers.
