Y=amount of money paid. (in $)
x=number of songs download.
We have this function:
y=0.25x+9.99
Then:
if y=113.74
113.74=0.25x+9.99
0.25x=113.74-9.99
0.25x=103.75
x=103.75 / 0.25
x=415
Answer: the number of songs downloaded would be 415.
Surface Area of a Sphere = 4π(d/2)²
Let the smaller sphere's diameter be just a sample of 4 units in diameter and let the large spheres diameter be 4 times that of the smaller sphere.
Small Sphere: 4π(4/2)² = 16π units²
Large Sphere: 4π(16/2)² = 256π units²
256π / 16π = 16 times
The large sphere has a surface area 16 times that of the smaller one.
153=9*17=3*3*17
so the prime factorization is 3*3*17 (also can be written
*17)
I am sorry i dont understand
You take the orignal price of the video game and subtract the new price to see how much it was reduced. 60-45 = 15. then you take the reduced amount of the game (15) and divide by the original price (60).
you get 25%
your answer is B
