Answer
B is the correct answer.
Step-by-step explanation:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31
0.1x + 0.25y = 5.2
Answer:
0.7 (rounded)
Step-by-step explanation:
Step-by-step explanation:
40 goals/60 games
40/60 = 0.7 (rounded)
So, the football player's rate of scoring per game is 0.7
A = 1/2h(b1 + b2)
A = 1/2*9.28(10.5 + 21.1)
Using calculator
A = 146.624 square cm

The center-radius form of a circle is the equation
(x - h)^2 + (y - k)^2 = r^2
where
(h,k) = center of circle
r = radius of circle.
Since the equation that was given is (x + 4)^2 + (y - 6)^2 = 25. then
(x - h) = (x + 4)
-h = 4
h = -4
(y - k) = (y - 6)
- k = - 6
k = 6
So the center is (h,k) = (-4,6)</span>
