A. 8 books on each shelf
B. 4 shelves for mystery, 7 shelves for biography
Divide by 1000 to convert to kilometers per minute
Then multiply by 60 to convert to kilometers per hour.
Conversion factor is 60/1000 = 0.06 answer
First picture:
2 and 7 are alternate exterior angles, which when added together need to equal 180 degrees.
Angle 7 = 180 - 146 = 34
Answer is B.34
Second picture:
Angle 8 = 48
Angle 8 + angle 7 = 180
Angle 7 = 180 - 49 = 131
Angle 5 and angle 7 are vertical angle, so angle 5 = angle 7 = 131
Angle 6 is a vertical angle to angle 8 so = 49
Angle 1 = angle 5 = 131
Angle 2 = angle 6 = 49
Angle 3 = angle 7 = 131
Angle 4 = angle 8 = 49
The diameter is twice as big as the radius
log x ( 5 × 12 ) = 7
x^7 = 60
