When you add 18 to 1/4 of a number you get the number itself

Answers

Answer 1

Answer:
-- Then when you only have 1/4 of the number, 18 must be
the missing 3/4 of it.

-- If 18 is 3/4 of it, then each quarter of it is 6 .

-- When you have all 4 quarters in the same place, if each one is 6,
then the whole thing must be 24.

Julia is saving money for the down payment on a car. She plans to save for one year. Her parents have offered to contribute $50 a month to her savings. How much does Julia need to save each month in addition to her parents' contribution if she wants to have a $2700 down payment on a car at the end of the year? Define a variable and write an equation to represent this situation.

Answers

Answer:

$12x+600=2700$

$175

Step-by-step explanation:

Let x represent money saved by her in one month.

So money saved by her in one year (12 months) would be $12x$ .

We can represent our given information as:

$12x+600=2700\n12x=2700-600\n12x=2100\nx=(2100)/(12)\nx=175$

Therefore, she needs to save $175 per month.

How do you " find, to the nearest tenth of an inch, the diagonal of a square whose perimeter is 28 inches ?"

Answers

Well if the perimeter is 28 inches, each side of the square is 7 inches. 28/4 = 7 because all sides of a square are the same.

If we split the square in half to create 2 triangles we can find the length of the diagonal. The two sides are the bases of 7 inches.

Use the Pythagorean theorem to solve for the hypotenuse or the diagonal.

7^2 + 7^2 = diagonal ^ 2

Therefore, the diagonal equals 9.9 inches.
