Take all Sara's money that she saved and add it together. Then minus 20.20 and 40.70 from Sara's saved money. With the rest of the Sara's money you have to subtract it from 130.10.

What is the inverse of y=(x+3)2<br><img src="https://tex.z-dn.net/?f=y%20%3D%20%28x%20%2B%203%29%20%7B%20%7D%5E%7B2%7D%20" id="T

Switch x and y
So
$x = {(y + 3)}^{2}$

Solve for y
$\sqrt{x} = y + 3 \\ y = \sqrt{x} - 3$
Inverse is
${f}^{ - 1} (x) = \sqrt{x} - 3$

The volume of a prism is 378CM2 one of the faces are 27cm 2 the edge is x, x=?<br> mathswatch.

olga_2 [115]

The length of the prism is 14 cm if the volume of the prism is 378 cubic cm and face area is 27 square cm.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

The question is incomplete.

The complete question is in the picture please refer to the attached picture.

We know the volume of the prism can be calculated:

Volume = base area×length

378 = 27x

x = 378/27 = 14 cm

Thus, the length of the prism is 14 cm if the volume of the prism is 378 cubic cm and face area is 27 square cm.

PLEASE HELP ME!!!!<br><br> (if you don’t know don’t answer)

Sergio039 [100]

Answer:

Here are my answers

hope this helps

Step-by-step explanation:

1. isosceles triangle

2. 3x + 15 = 90 x = 25

x + 25 = 90 x = 65

x + 55 = 90 x = 35

3. The size for DAB is 84

My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.

Robert wants to build a square sandbox that has an area of 25 feet. How long will each side be?

vova2212 [387]

Area = SxS
So sqaure root 25 = 5ft.
