2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.
To turn 32/64 into a percent, you have to divide the numerator by the denominator and then multiply the answer by 100.
So, for this question, divide 32 by 64 which is 0.50. Multiply this decimal by 100 and you get 50.
So 50% is the percent for 32/64.
Hope it helps :)
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The length from b to the centre is 14 as the radius is 9 and the outer length is 5. Therefore if ab is a tangent, pythagoras theorem would apply in that 9^2 + 12^2 should equal the hypotenuse squared. However 14^2 does not equal 9^2 + 12^2 so the answer is option 2.
15/3=5
5 would be the answer since 15 can be evenly divided by 3
