Answer:
A = 27π cm² or A ≈ 84.823... cm²
Step-by-step explanation:
From being shown that the missing area is 90 out of 360°, we know that we need to find 75% of the area of the given circle.
Our equation is altered to: A = 0.75πr²
Plug in: A = 0.75π(6)²
Multiply: A = 27π cm²
If you were instructed to multiply pi and round (which is not as probable given that this is RSM), then the answer would be A ≈ 84.823... cm²
Define your variables:
Q: number of quarters
D: number of dimes
Next, create your equations
Q = 2D-4
25Q+10D=200
Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5
Substitute D back into the other equation to find Q.
Q=2D-4
Q=2(5)-4
Q=6
Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200
This works, so the answer is right! Bill has 6 quarters and 5 dimes.
Since one ton is 2000 pounds, 2.25 tons is equal to 4500 pounds. Now do
4500-2150=2350
So he can carry 2350 more pounds

Answer:
Step-by-step explanation:
The function whose graph is given has y-intercept (0, 3), whereas the function f(x) has y intercept (0, 1). So it is the first that has the greater y intercept.
