Answer:
The Musician had $29 before performing at the fairs
Step-by-step explanation:
Let the initial amount musician has be x
At the first musician doubled his money and spent
$30 , this can be written as
2(x) -30---------------------------------(1)
At the second he tripled his money and spent $54.
3(2x -30) - 54
=> 6x-90-54
=> 6x- 144--------------------------------(2)
At the third, he quadrupled his money and spent $72
4( 6x- 144) - 72
24x - 576 - 72
24x -648-------------------------------(3)
At-last he had $48
24x -648 = 48
24x = 48+ -648
24x =696
x = 
x = 29
Here's the formula you need to use:
The volume of any cylinder is = (pi) x (radius)² x (height) .
Take that formula.
Write your "3 inches" in place of "radius".
Write your "12 inches" in place of "height".
Write "3.14" in place of "pi".
Do the arithmetic, and bada-bing, you'll have the volume.
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Two secants drawn from outside the circle, then
The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) ← distribute both sides
9 + 3y = 2 × 11
9 + 3y = 22 ( subtract 9 from both sides )
3y = 13 ( divide booth sides by 3 )
y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
