How much taller was Mt. Everest determined to be in 1999, than in 1852? 11 meters 12 meters 22 meters 147 meters

Answers

Answer:

11 meters

Step-by-step explanation:

In 1852 its height was 29.002ft or 8.839m, while the measuring in 1999 said that it was 29.035ft or 8.850m. That means that it is taller by some 11 meters or 33 feet. That is because it keeps increasing its size since its positioned on such plates that hit each other.

Answer:

11 meters

Step-by-step explanation:

Use the distributive property to write an expression that is equivalent to 10a - 15b + 25 in factored form.

Answers

Using the distributive property:

10a - 15b + 25

(10a - 10b) - 5b + 25

10(a - b) - 5b + 25

(10(a - b) - 5)b + 25

((10a - 10b) - 5)b + 25

(Factored form)

To rewrite this equation, we must identify a common factor of all these numbers. Because 5 goes into all the numbers, that is our common factor. Now, we use 5 to distribute the equation:

10a - 15b + 25 —> 5(2a - 3b) + 25

Hence, the distributed expression would be:

5(2a - 3b) + 25

Answers

Answer:

To find the answer to all questions do this....

Step-by-step explanation:

Solving problem #1 as an example:

-Set up an equation with two "fractions" equal to eachother.

-have the total amount (196) equal 100

ex. ?/196 = ?/100

-then find the percentage asked b placing the percent over 100

ex. 5/100

- from there solve by multiplying the percent (5) to the total amount (196) and divide that answer by 100.

-finally you should get your answer of 9.8

*** to check your work simply set up your answers

ex. 9.8/196 = 5/100

and multiply the numbers diagonally from eachother

ex. 9.8×100 and 196×5

If your answer is correct, you should get the same number on both sides

980=980

Number 1 9.8
Number 264.5
Number 3 .8
Number 4 4.4
