A) D + Q = 124
B) .10D + .25Q = 20.50
Multiply B) by -4
B) -.40D + -Q = -82.00 then add to A)
A) D + Q = 124
.60 D = 42
D = 70 Dimes
Q = 54 Quarters
A roll of quarters = $10 = 40 Quarters so there will be 14 "extra" quarters.
Answer:
33.33%
Step-by-step explanation:
The line of best fit for the data is represented by the equation y = 3x + 15.
At x = 4,
y = 3(4) + 15 = 27
At x = 7,
y = 3(7) + 15 = 36
We need to find the percent change in the total number of trees from x = 4 to x = 7.
So,
So, the required percentage change is equal to 33.33%.
Answer:
We can write sin 21° as 1200 / x and also 0.36 so we can write:
1200 / x = 0.36
1200 = 0.36x
x = 1200 / 0.36
x ≈ 3333 ft
<span>We want to know what force is always pointed towards the center. In order for the motion to be circular, a force must act constantly towards the center of the curvature of the path. It's name comes from Latin: "centrum" is center and "petere", to seek. So we get centripetal force. </span>
Answer:
504/(surface area of all walls)
Step-by-step explanation:
Assuming Length=l, breadth=b and height=h
Surface Area of all walls= 2×l×h+2×b×h
Cost per square ft of wall paper= 504/(surface area of all walls)
