Answer:

11+ 9 = 20

Step-by-step explanation:

=> 21-9=11

21 - 9 equals to 11 is actually a wrong answer

So in order to find the subtraction problem that will help us truly know whether the equation is wrong

=> 11+ 9 = 20

OR THE SECOND EQUATION IS

=> 21 - 11 = 10

Answer:

1350 cm^2

A=6a^2= 6 x 15^2 = 1350^2

Answer:

B. 1350 cm^2

Step-by-step explanation:

Hello!

To start, let's understand what surface area is. The surface area is all the space on the outside of the shape.

In this case, we see that the entirety of the outside of the shape is made up of 6 different faces.

We know that this is a cube, so all the measurements of length and width are the same. We are given 15 for one of those, so we know that length and width are all 15.

Because we already determined that the surface area is all the face areas added up, we can now follow that pathway.

We know that there are 6 faces that are equal in the area (due to it being a cube). We also know that the width is the same as the length. That means the area of one face in the cube would be 225 cm^2. Since there are 6 of those faces, we multiply that by 6. 22*6 = 1350 cm^2

That's your answer.
Let me know if you have any questions.

Step-by-step explanation: 3x+2x=-2x+5+2x

Answer:

The answer is f^-1(x)=0^3[tex]\sqrt{x}[/tex]+2

Step-by-step explanation: Now we just change y back to f(x) and add a 0−1 to write it in inverse notation We begin with f(x)= x 3−2 . To find the inverse of any equation, just switch x and y No, before we do that, I'm going to change the equation. I'm going to rename f(x) to y , just so that I don't have to deal with the parentheses or anything. Now, all I have to do is change what f (x) is called, not it's actual value. Anyways, we have y = x 3 − 2 Now we switch x and y and then solve for y Now we've got x = y 3−2 If we add 2 on both sides we have x + 2 = y 3 Now we just need to get y as simple as possible, which we'll do by cube rooting both sides of the equation. That leaves us with y=0 3√x+2 Now we just change y back to f(x) and add a 0−1 to write it in inverse notation

The percentage increase in average miles flown per passenger from 1966 to 1976 is 16.9%.

An equation is an expression that shows the relationship between two or more numbers and variables.

In 1966, the average miles flown per passenger was 711 while in 1976, the average miles flown per passenger was 831. Hence:

Percentage increase = [(831 - 711) / 711] * 100% = 16.9%

The percentage increase in average miles flown per passenger from 1966 to 1976 is 16.9%.

Answer:

The surface area of the raised flower bed is 499 feet. The volume of the solid it holds is 300.

Answer:

Step-by-step explanation:

First, let's find the surface area of both the triangles

5x3=15

So, the surface area of the triangles is 15 sq.cm

Now, let's find the surface area of the base (large rectangle in the middle)

12x8=?

10x8=80

2x8=16

80+16=96

12x8=96

So, the surface area of the base, is 96sq.cm

Now, let's find the surface area of both of the side rectangles

12x5=60

60x2=120

So, the surface area of the two side rectangles is 120sq.cm

Now, let's find the total surface area by adding all of our answers.

120+96=216

216+15=231
