Answer:
Sonya is ten her mother is 22
Step-by-step explanation:
Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.
Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20
Therefore, one person saved 20 and the other saved 20 + 15 = 35.
Area of the quarter sector
Area of the entire circle = pi * r^2
Area of the quarter circle = pi r^2 / 4
r = 9
Area of the quarter circle = pi 9^2 / 4
Area of the quarter circle = pi 81/4 = 20.25 pi
Area of the triangle
Area pf the triangle = 1/2 b*h
b = h = r
r = 9
Area of the triangle = 1/2 9 * 9
Area of teh triangle = 1/2 81
Area of the triangle = 40.5
Area of the shaded area
The shaded area = Area of the 1/4 circle - area of the triangle
The shaded area = (20.24 pi - 40.5)ft^2

At the same rate Teresa would drive 567mi.
756/12 = 63
63 x 9 = 567
Step-by-step explanation:
since PQRT is a rhombus,
URQ=TPU
y=180-90-24=66
x=180-32-90-24=34
