Using proportions, it is found that Mason ran 620 meters.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Considering the ratio, the <em>rule of three</em> is given as follows:
2 laps for Mason - 3 laps for Laney.
n meters for Mason - 930 meters for Mason.
Applying cross multiplication:
3n = 930 x 2
n = 930 x 2/3
n = 620
Mason ran 620 meters.

Answer:
422.16
Step-by-step explanation:
Area of circle
A=π²
(3.14)×(12²)
(12²)=144
(3.14)×(144)=452.16
Area of rectangle
10×3=30
452.16-30=422.16
Answer:
9π, or 28.26
Step-by-step explanation:
The Arc of the semicircle is the circumference of half a circle.
The radius of the semicircle is 9, and the circumference of a circle is 2πr, so it is 2π9 = 18π. since this is a semicircle, it is half of that, so 9π, or 28.26, since π is 3.14 here
(2^4)^2 x 2^0
(2^4)=2x2x2x2=16
16^2=16x16=256
2^0=1
256x1=256
