Answer:
Your answer is 2/1. 2 donuts every minute.
Step-by-step explanation: The rate you are given is 30 donuts every 30 minutes. This equals 30/15.
To make a unit rate, you must make the fraction have a ratio of x/1. You can simply do this by dividing and/or simplifying the equation 30/15.
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

Answer:
12.5 feet
Step-by-step explanation:
how to:
lets find the angle that corresponds with the 10 foot side.
to do that we add 50 degrees plus 90 degrees (right angle) to get 140 degrees.
as we know, a triangles angles will total 180 degrees, so 180 - 140 = 40 degrees for the angle corresponding to the 10 foot side.
put these into ratios:
<u>Angle A </u> = <u>Angle B</u>
side a side b
now plug in our numbers:
<u>50 degrees</u> = <u>40 degrees</u>
X 10 feet
Cross multiply:
50 (10 feet) = 40 (x)
solve for x:
500 = 40 (x)
500/40 = x
12.5 = x
