Determine the measures of all unknown angles and side lengths of δpqr. round side lengths to the nearest hundredth. m∠r = ° pr ≈ pq ≈

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

perpendicular to x*4 means it's y = -1/4*x+k

so for y = 7 and x = 2

we have 7 = -1/4*2 + k so k = 7.5

so the equation is   y = -1/4x + 7.5
