Answer:
2.99 cm
Step-by-step explanation:
V= 
(pi)(r^3)=113.04cm^3
113.04/ (pi) = r^3 = 26.99
r=![\sqrt[3]{26.99}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B26.99%7D)
= 2.99cm
Answer:
118 yards
Step-by-step explanation:
Tamia is getting balloons for her father's birthday party
She wants each balloon to be 6 feet long
Tamia wants to get 59 balloons
Therefore the yards of string needed can be calculated as follows
= 59×6
= 354 feet to yards
= 118 yards
Hence the number of yards needed is 118 yards
4/9+1/5=20/45+9/45=29/45 of the wall is covered up by two couches
Answer:
The value of x is -2 and 2.
Step-by-step explanation:
When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :
x² - 3x - 1 = -3x + 3
x² - 3x - 1 + 3x - 3 = 0
x² - 4 = 0
Next, you have to factorize and solve it :
x² - 4 = 0
x² + 2x - 2x - 4 = 0
x(x + 2) - 2(x + 2) = 0
(x + 2)(x - 2) = 0
x + 2 = 0
x = -2
x - 2 = 0
x = 2
