Mental way:
415 / 51.9 * 100 = 800 students in the school.
detailed way:
x is the amount of students in the school.
51.9% * x = 415
(divide both sides by 51.9% (or 0.519))
x = 800 students
Answer:
300 calories
Step-by-step explanation:
he burns 12 calories each lap so you need to know how many laps he ran
which means you need to find the circumference of the track, whose formula is 2πr; remember, radius is half the diameter.
C = 2π75
C = 150π
C ≈ 471
Now divide the total number of feet he ran (11,775) by the circumference to arrive at the number of laps.
11775 ÷ 471 = 25 laps
25 x 12 = 300 calories burned in total
Answer:
i really don't know but good luck
Step-by-step explanation:
The distributive property: a(b + c) = ab + ac
(3 - 5u + 3x)(-3) = (3)(-3) + (-5u)(-3) + (3x)(-3) = -9 + 15u - 9x
<h3>Answer: (3 - 5u + 3x)(-3) = -9 + 15u - 9x</h3>
