Answer 1

Answer:

Answer: Im pretty sure its x = 4.472135955

Step-by-step explanation:

DISCLAIMER: I may be wrong I am kind of rusty.

You got to use the Pythagorean theorem (a^2 + b^2 = c^2) to answer this.

First you label your triangle by putting the hypotenuse as "c" the other known value as "b" and the unknown value as "a".

Now you input the answers into the equation.

x^2 + 4^2 = 6^2

Now answer the known values.

x^2 + 16 = 36

Now subtract by 16 to get rid of the sixteen.

x^2 + 16 -16 = 36 -16

x^2 = 20

Now to get rid off the ^2 find the square root.

x = 4.472135955

Answers

27 - 15 = 12
Adding 15 to both sides, we have,
27 - 15 + 15 = 12 + 15
i.e. 27 = 12 + 15
Answer: C [12 + 15 = 27]

To calculate by estimation, round each number to the nearest ten, hundred, ets as the case may be.
Here, rounding to the nearest ten, we have,
267 - 154 = 270 - 150 = 120.
Answer: C

Quotient of 18 and 2 = 18/2 = 9
Sum of 22 and 9 = 22 + 9 = 31
Subtracting the quotient of 18 and 2 from the sum of 22 and 9, we have:
31 - 9 = 22

Ralph bought and 8foot long copper pipe he used 85 investors of the copper pipe how many inches of pipe were left over

Answers

Convert the total length of the pipe from feet to inches.

1 foot = 12 inches.

8 feet x 12 inches = 96 total inches.

96 inches - 85 inches = 11 inches are left over.

Final answer:

After converting the length of an 8-foot copper pipe to inches, we find it is 96 inches long. Ralph used 85 inches of the pipe, leaving 11 inches of the copper pipe leftover.

Explanation:

Ralph bought an 8-foot long copper pipe. Initially, we need to convert the length of the pipe from feet to inches since the part used is given in inches. 1 foot equals 12 inches, so an 8-foot pipe is 8 * 12 = 96 inches long. Ralph used 85 inches of the pipe. So, to find out how much is left over, we subtract the amount used from the total length of the pipe: 96 inches - 85 inches = 11 inches. Therefore, Ralph has 11 inches of copper pipe left over.
