Answer:
17
Step-by-step explanation:
If it costs $20 for the membership fee, then you can subtract that from the total monthly cost, giving you $25.50.
Then, you can divide this number by the price of each song to work out how many songs you downloaded, because you are simply rearranging the formula to work out the total price. $25.50 / $1.50 = 17.
43*((100+18)/100)
43*(118/100)
43*1.18=50.74
Hope this helps :)
Answer:
D
Step-by-step explanation:
Start by subtracting 64 from both sides:
Factor this by taking roots. Divide both sides by 25 first:
We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are
Since the legs are the same length, we know that the remaining two angles must be the same.
120+2x=180
2x=60
x=30
Final answer: x=30 degrees
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.
