C. 42.39 times 0.1 is 4.239. 42.39-4.239= 38.151 which rounds to 38.15
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:

In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So 
Then

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.

From the first equation:



Replacing:







Her average speed is 48 miles per hour.
First you multiply how much they make per hour by the number of hours they worked that weren’t overtime. So you would multiply 4.9 and 40.
4.9(40)=$196
Then you multiply 7.35 and the number of hours worked overtime. To find the number of hours worked overtime you would subtract 40 from 46.
46-40=6
Now you multiply again.
7.35(6)=$44.10
Then you add the two amounts made together.
196+44.10=$240.10
The student makes $240.10.
Answer:
-7/10 is greater than -13 1/2: >
Step-by-step explanation:
We know this because -7/10 is closer to 1 than -13 1/2, meaning it is the larger number.
