[tex]\sqrt[3]{488+24} \\[/tex]
Answer:
8
Step-by-step explanation:
First, add the values inside the radical
488+24 = 512
[tex]\sqrt[3]{512}[/tex] = x
This means that: [tex]x^{3}[/tex] = 512
Therefore, x must be equal to 8.
[tex]\sqrt[3]{512}[/tex] = 8

Exponents
168+8+27-20
Addition
203-20
Subtraction
183
183 is the answer.
Answer:
10
Step-by-step explanation:
Using the process PEMDAS I got the answer 10.
168÷2^3+3^3-20
There are no parentheses so you solve the exponents first.
168÷8+9-20
Next, we do not multiply which makes division our second step.
This gives us 21+9-20.
Now we add 21+9 which gives us the sum of 30.
30-20 is equal to 10.

which expression has a value of 6 when x=2 and y=4?
Let's verify all the options to the question. Clue given: x = 2, y = 4
Option A:
(x² + 8) ÷ y - 2
=> (2² + 8) ÷ 4 - 2
=> (4 + 8) ÷ 4 - 2
=> 12 ÷ 4 - 2
=> 3 - 2
=> 1 ≠ 6
This answer does not equal 6.
Option B:
(x² + 8) ÷ (y - 2)
=> (2² + 8) ÷ (4 - 2)
=> (4 + 8) ÷ (4 - 2)
=> 12 ÷ 2
=> 6 = 6
This answer is correct as 6 = 6.
Option C:
x² + 8 ÷ (y - 2)
=> 2² + 8 ÷ (4 - 2)
=> 4 + 8 ÷ 2
=> 4 + 4
=> 8 ≠ 6
This answer does not equal 6.
Option D:
x² + 8 ÷ y - 2
=> 4 + 8 ÷ 4 - 2
=> 4 + 2 - 2
=> 4 ≠ 6
This answer does not equal 6.
So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

Solve: 14+(5x-7)=19+3x
The answer is x=6, have a good day!
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
First let's put our equation
[tex]14+(5x-7)=19+3x[/tex]
Let's drop our parenthesis[tex]14+5x-7=19+3x[/tex]
Subtract 3x from both sides[tex]14+2x-7=19[/tex]
Simplify[tex]7+2x=19[/tex]
Subtract 7 from both sides[tex]2x=12[/tex]
Divide both sides by 2[tex]x=6[/tex]

A rectangular community swimming pool is 31 2/3 meters long and 7 1/5 meters wide. The area around the swimming pool is covered with tiles. The area covered with tiles is 25% of the total area covered by the swimming pool. The total cost of the tiling is $712.50. What is the cost of the tiling per square meter?
Answer:
$12.50
Step-by-step explanation:
First, we find the area: 31 2/3 * 7 1/5 = 95/3 * 36/5 = 3,420/15 = 228 square meters. Then, we find the part that the tiles cover: 228 * 0.25 = 57 square meters. Now, we find the cost of the tiling per square meter by dividing the total cost by the total amount of tiling: $712.50 / 57 = $12.50. $12.50 will be your answer.
