x= -10
Step-by-step explanation:
Answer:
$1620
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( s is the length of the side )
Here V = 5832 , then
s³ = 5832 ( take cube root of both sides )
s = ![\sqrt[3]{5832}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5832%7D)
= 18 ft
The area of the square floor is then
area = 18² = 324 ft²
cost = 324 × $5 = $1620
Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
Answer:
It is the Last answer D
Step-by-step explanation:
because 15/2 is equal to 7 1/2
the square room of 64 is 8
and 8.1444444 is less than 8 1/7
Answer:
x≈ -4.71
Step-by-step explanation:
7(x+6)=9
Distribute the 7 into the parenthesis.
7x+ 7(6)= 9
Multiply the numbers.
7x+ 42= 9
Subtract from both sides.
7x+42= 9
-42 -42
Now, divide to both sides.
<u> 7x</u>= <u>-33</u>
7 7
x= -4.71428571429
x≈ -4.71
