p varies directly as q and inversely as r. One set of values is p = 5, q = 1, and r = 2. Find p when q = 10 and r = 50.

P = kq/r

5 = k*1/2
k = 2*5 = 10

p = 5*10/50 = 1
P is 1.

Hope it helps!

Answer:

<u>XZ is longer than XY</u>

Step-by-step explanation:

First we can notice all of the answers consist of knowing the lengths, so we must now find the lengths for each segment. To do this, we must use the pythagorean theorem.

(1, -1) and (-5, -5)

-5- -1 = -4

-5-1 = -6

-4^2+-6^2 = c^2

16+36 = c^2

52 = c^2

7.21110255 = c

So, the length of XZ is 7.21110255 units long

(1, -1) and (8, -2)

8-1 = 7

-2--1 = -1

7^2+-1^2 = c^2

49+1 = c^2

50 = c^2

7.07106781 = c

So, the length of XY is 7.07106781 units long.

<u>XZ is longer than XY</u>

Angle 2 is 110 degrees. Allen claims that we do not have enough information to solve for angle 1. Is he correct? Why or why not?

devlian [24]

Allen's claim that we do not have enough information to solve for angle 1 is incorrect

<h3>How to calculate the measure of angle 1</h3>

Given that:

Angle 2 = 110 degrees

Angle 1 and angle 2, are the only angles on the straight line.

So, we have:

$\angle 1 + \angle 2 = 180$

Substitute 110 for angle 2

$\angle 1 + 110 = 180$

Subtract 110 from both sides

$\angle 1 = 70$

The measure of angle 1 is 70 degrees.

So, we can conclude that Allen's claim is incorrect
