180°. :)
All angles in a triangle sum to 180° proof.
If a fish grows 20 inches per 5 months, that means that the fish grows 4 inches a month (20/5).
Using this, multiply 8x4 to get 32, which is your answer.
The fish will grow 32 inches in 8 months. Hope this helps!
Estimate -6.1(0.22)
Answer:
Use rounding to get -6(0.2), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Round the factors to the nearest whole number, and then multiply.
Step-by-step explanation:
Actual answer:
-6.1(0.22) = -1.342
Estimate answer:
-6 (.2) = 1.2
First, convert 625 revolutions per minute to revolutions per hour: 625*60=37500 revolutions per hour
Next you can simplify 88 feet for 11 revolutions to 8 feet per revolution.
To find how many feet per hour you are travelling, multiply 37500 by 8 ft., which results in 300000 feet per hour.
Then you have to convert 300000 ft. per hour to mph. There are 5280 feet in a mile, so divide 300000 by 5280 to get approx. 57 mph.
