Answer: m∠QPR = 40

<h2>Step-by-step explanation:</h2>

Because PG is perpendicular to PS, it is safe to assume that angle QPS is 90 degrees.

(7x-9) + (4x +22) = 90

x = 7

Because we need to find the degrees of QPR, plug in the equation for that angle with the value of x we found.

7(7) - 9 = 40

m∠QPR = 40

Rich has a bag of 24 pencils. Each pencil is 19 centimeters long. What is the combined length of the pencils in meters
Roman55 [17]

Multiply the number of pencils by the length to get total centimeters first, then convert to meters:

24 x 19 = 456 cams.

1 meter = 100 cm

Divide total cm by 100 to get meters

456 / 100 = 4.56 meters
