Answer: 80 sq. ft
Step-by-step explanation:
Company A’s charges can be represented by the equation: 10m + 250
Company B’s charges can be represented by the equation: 12m + 90
To find when the square feet got which they have the same amount, I will set them equal to each other and solve for it.
10m+250=12m+90
-10m -10m
250=2m+90
-90 -90
160=2m divide both side by 2
80=m
For 80 square feet, both companies charge the same amount.
Answer:
20 in^2
Step-by-step explanation:
The end is a trapezoid
The area of a trapezoid is
A = 1/2 (b1+b2) *h
where b1 =4 and b2 =6 and h =4
A = 1/2 (4+6) *4
A = 1/2 (10)*4
=20 in^2

Answer:
Step-by-step explanation:
average of x-coordinates = (7+1)/2 = 4
average of y-coordinates = (-3-1)/2 = -2
center of circle: (4,-2)
radius = distance between (1,-1) and (4,-2)
= √((4-1)²+(-2-(-1))²)
= √10
equation of circle:
(x-4)² + (y+2)² = 10
