What is the unit rate of 600 miles in 7 hours ?

Answers

The unit rate of 600 miles in 7 hours is 85.71 miles per hour.

Given that, distance= 600 miles and time= 7 hours.

What is the unit rate?

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Here unit rate is

Speed =Distance/Time

= 600/7

= 85.71 miles per hour

Therefore, the unit rate of 600 miles in 7 hours is 85.71 miles per hour.

L+15.2=-4.5
Solve for L explain

Answers

L= -19.7

You first subtract 15.2 on both sides because you need to get rid of the 15.2. 15.2-15.2=0 and you would be left with the answer L= -19.7

your answer will be -19.7
$- 4.5 - 15.2 = - 19.7$

One angle in a right triangle measures 15 degrees.what is the measure of the other acute angle in this triangle?A)65 degrees
B)75degrees
C)105degrees

Answers

angles add up to 180
if right triangle, one angle is 90
another is 15 as given therefor
180=15+90+x
180=105+x
subtract 105
75=x

angle is 75 degrees

answer s B

because all triangles angles add up to equal 180, and a right triangle has a 90 degree angle. you subtract 90 and 15 from 180 and that number will be the size of the remaining angle

180-90=90

90-15= 75

the answer is B) 75degrees
