If x is the number,

\sqrt{x} -(- \sqrt{x} )=30

(The difference or distance between two numbers is the larger one minus the smaller one.)

2 \sqrt{x} =30 \\  \sqrt{x} =15 \\ (\sqrt(x))^2=15^2 \\ x=225

Eliza bought 2 2/4 yards of fabric. She cut off 3/4 yards to make an art project. What fraction offabric is left?
mina [271]

Answer:

7/4 or 1 3/4

Step-by-step explanation:

Think of 2 2/4 to be 10/4 because you need to multiply the 2 to the 4 which makes 8 and then add 2 to get 10/4.

When you get 10/4 subtract it with 3/4 to get 7/4.

You can leave it as 7/4 or 1 3/4.

The dashed-lined figure is a dilation image of EFGH. Is D(n,H) an enlargement or a reduction? What is the scale factor n of the
alexandr1967 [171]

Answer:

n = 3; enlargement

Step-by-step explanation:

The dashed-line figure is larger. That is the meaning of "enlargement."

Points on the dashed-line figure are 3 times the distance from point H as the corresponding point on the sold-line figure, so the scale factor is 3.

Can someone help me with the steps to solving<br> 22-5(6v-1)=-63
faust18 [17]
22 - 5(6v - 1) = -63 First, you distribute 5 to the parentheses.

22 - 30v + 5 = -63

27 - 30v = -63

-30v = -90

v = 3

           A circle's radius is 0.3 yd. What is its area?

\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}

   

Formula for Area of a Circle:-

⇒ A=πr²

<u>Where</u>

  • A = area
  • π = pi, 3.14
  • r = radius, 0.3 yd

Substitute:-

A=π(0.3)²

On simplification,

A=0.09π

On further simplification,

⇒ A=0.283 yd²

<h3>Good luck.</h3>

sergij07 [2.7K]
If you are given $10 every 3.5 hours and you want to find the unit rate per hour, you want to solve for how much money you make every hour. You do this by dividing the $10 by the 3.5 hours, which will result in about $2.86 per hour. (This is a rounded value)
