Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b =
= 60
126 times 10 and whatever that answer is is the volume
1/2+1/8+1/4=7/8
4/8+1/8+2/8=7/8
1-7/8 = 3/8
the fourth on inherited 3/8 of the estate.
Answer: He paid
for the T.V.
Step-by-step explanation:
We need to analize the information provided:

- Joseph buys it at 35% off the original cost.
Let be "x" the amount Joseph paid for the T.V.
We can calculate "x" with the following expression:

Therefore, he paid
