This is not written correctly. What is the question? What do I need to find out?
4/5 of 80 is 64
99-64=35
35/5=7

Answer is 56
249 km in 3 hours are 83 km in 1 hours
249 : 3 = 83 Km
Answer:
400 degrees
Step-by-step explanation:
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
Step 3 : Round it to nearest 100
Since 20 is closer to 400 than 500 therefore it will be rounded off to
400 degrees
!!
The estimated lengths are 12in. and 5 in. This would be an estimated difference of 7in.
The estimated difference is going to be higher than the actual difference because in rounding 11.7 to 12, you are losing .30in, but in rounding down 5.25 to 5, you are actually gaining .75in.
The ACTUAL difference is 6.45in
