Answer:
1.7 miles.
Step-by-step explanation:
We have been given that Mark runs back and forth on a football field for a total of 3000 yards.
Since we know that 1 mile equals to 1760 yards. To find the number of miles Mark ran we will divide 3000 yards by number of yards in one mile (1760).

After cancelling out yards from numerator and denominator we will get,

Therefore, Mark ran 1.7 miles on the football field.
Step-by-step explanation:
5x+2y=-11
2x+2y=5
so you find values that match or can multiply by something to match-2
5x+2y=-11
- 2x+2y=5
=3x+0y=-16
3x/3=-16/3
x=5 1/3
then substitute x in one of the equations to get y
ANSWER
9
EXPLANATION
We want to find the distance between the points (3, -5) and (-6, -5).
The given points have the same y-coordinates .
This means it is a horizontal line.
We use the absolute value method to find the distance between the two points.
We find the absolute value of the distance between the x-values.
The distance between the two points is
|3--6|=|3+6|=|9|=9
Answer: C . 147π / 4 mi²
Concept:
The sector is the part of a circle is enclosed by two radii of a circle and their intercepted arc.
A = (θ / 360) πr²
θ = angle of the sector
π = constant
r = radius
Solve:
<u>Given variable</u>
θ = 270°
r = 7 mi
<u>Given formula</u>
A = (θ / 360) πr²
<u>Substitute values into the formula</u>
A = (270 / 360) π (7)²
<u>Simplify exponents</u>
A = (270 / 360) π 49
<u>Simplify by multiplication</u>
A = (147 / 4) π
A = 147π / 4
