A carpenter is making a shelf in the shape of a parallelogram. She begins by drawing parallelogram RSTU on a coordinate plane wi

olchik [2.2K]

The coordinates would be (3, 3).

The slope from R to S is given by

m = (0 - 0)/(-4-1) = 0/-5 = 0

The distance from R to S is 5 units straight across.

This means the slope from T to U will be 0, and it will be a horizontal segment. This means the y-coordinate of U will be 3, since the y-coordinate of T is 3.

The distance from T to U will be 5 as well; -2+5 = 3 for the x-coordinate.

This makes the point (3, 3).

Answer:

Step-by-step explanation:

The formula for this is

∠G = 1/2(arcEH - arcHF)

We have angle G (5x - 10) and we have arcEH (195) so we have to solve for x to find the measure of arcEHF so we can add arcEH + arcHF = arcEHF

Filling in the formula with what we have:

$5x-10=\frac{1}{2}(195-(8x+17))$

which simplifies down a bit to

$5x-10=\frac{1}{2}(195-8x-17)$ which simplifies down a bit more to

$5x-10=\frac{1}{2}(178-8x)$ Multiply both sides by 2 to get rid of the fraction and get:

2(5x - 10) = 178 - 8x which of course simplifies to

10x - 20 = 178 - 8x. Now add 8x to both sides and at the same time add 20 to both sides to get:

18x = 198 so

x = 11. Now we can find the measure of arcHF:

arcHF is 8x + 17, so arcHF is 8(11) + 17 which is 105°.

arcEH + arcHF = arcEHF so

195 + 105 = arcEHF so

arcEHF = 300°

Written as a percent, what is the probability of getting an odd number on a spinner with 4 equal parts numbered 1 to 4?A.20%B.25

Komok [63]

Answer:

C: 50%

Step-by-step explanation:

There are 2 even numbers and 2 odd numbers on the spinner.

Therefore, the probabilty of getting an odd number is 2/4 = 1/2 = 0.5 = 0.5 x 100 = 50%

Nan bought an $85 dress on sale at 25% off the orignal price. she paid 5% sales tax on the sale. what was her total bill?

Tema [17]

25% = 85 / 4 = $21.25 off
5% = 85 / 20 = $4.25
75% = 21.25 • 3 = $63.75
$63.75 + $4.25 = $68

Her total bill was $68
