Answer: 20.48

Step-by-step explanation:

use the pythagorean theorem for the diagnal sides

3^2+3^2=c^2

9+9=c^2

18=c^2

[tex]\sqrt{18}[/tex]

this gives you 4.24

now add 6+6+4.24+4.24 to get 20.48

Answer:

x ≤ 40

Step-by-step explanation:

Given:

[tex]\displaystyle \large{\dfrac{x}{-8} \geq -5}[/tex]

Multiply both sides by -8 to get clear out the denominator:

[tex]\displaystyle \large{\dfrac{x}{-8}\cdot (-8) \geq -5\cdot (-8)}\\\displaystyle \large{x\geq 40}[/tex]

Because the LHS (Left-Handed Side) expression is in negative, make sure not to forget to swap the sign from ≥ to ≤

Hence, the solution is x ≤ 40

Option A

Answer:

Count the distance across from point A to point B

To make this easier, bring point B to the same height level as point A then count the units over.

If we bring point B two units up, we can see that the distance between point B and A is 6 units apart.

Answer:

I think the answer will be 32,768 cubic units..

Step-by-step explanation:

The volume formula is length times width times height and you say that the area of the shaded face is 96 square cm is better we divide

96/3 =32

So, we took the colume formula like this:

V= L x W x  H

  = 32 x 32 x 32

  =  1,024    x  32

  =   32,768 cubic units

Now, substituting the values :

⠀

[tex]{\longrightarrow \qquad \sf{ 2 \times 3.14 \times r = 122}}[/tex]

⠀

[tex]{\longrightarrow \qquad \sf{ 6.28 \times r = 122}}[/tex]

Answer:    Find the area of the trapezoid!

= 1012 meters

Step-by-step explanation:

Surface Area = 2×(12×13 + 12×14 + 13×14)

Hopefully this helps you!

-Keira

Answer:

169 mi²

Step-by-step explanation:

To find the area of a trapezoid, use this formula:

[tex]A=\frac{a+b}{2} h[/tex]

"a" and "b" represent the two bases (12 mi and 14 mi), and the "h" stands for height (13 mi). Insert these values into the equation.

[tex]A=\frac{12+14}{2} 13[/tex]

[tex]A=\frac{26}{2} 13[/tex]

[tex]A=13 * 13\\= 169[/tex]

Therefore, A = 169. :)

Answer:

0.6796875

Step-by-step explanation:

1. We assume, that the number 9.375 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 9.375 is 100%, so we can write it down as 9.375=100%.

4. We know, that x is 7.25% of the output value, so we can write it down as x=7.25%.

5. Now we have two simple equations:

1) 9.375=100%

2) x=7.25%

where the sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

9.375/x=100%/7.25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7.25% of 9.375

9.375/x=100/7.25

(9.375/x)*x=(100/7.25)*x       - we multiply both sides of the equation by x

9.375=13.793103448276*x       - we divide both sides of the equation by (13.793103448276) to get x

9.375/13.793103448276=x

0.6796875=x

x=0.6796875

now we have:

7.25% of 9.375=0.6796875

The percentage of the mile 7.25% of 9.375 =0.6796875.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have to find percentage of the mile times range from 7.25 to 9.375.

let 9.375 represents 100% and x represents 7.25%.

Then, using proportion we can write

9.375/x=100%/7.25%

9.375/x=100/7.25

9.375 (7.25)= 100x

100x = 67.96875

x= 0.6796875

Thus, 7.25% of 9.375 =0.6796875

Answer:

4 problems

Step-by-step explanation:

(I'm going to type a lot, but it isn't at all hard when you really understand and get the hang of it) If you are assigned 32 math exercises for homework and you complete 87.5% of them, this means that the problem is not asking for 87.5 % of 32, but what is left after you finish 87.5%, which means we should subtract 87.5 from 100. 100-87.5=12.5. 12.5% now represents the percent of the 32 original questions we have left to do after dinner. So, now we need to create a proportion. 12.5% means 12.5% out of 100%, with the 100% meaning 32, because that is the total amount of questions we have. so, this means we have [tex]\frac{12.5}{100}[/tex]. To use this to solve our problem, we have to act as if the 32 also represents 100%. So, we have to multiply this fraction ([tex]\frac{12.5}{100}[/tex]) by [tex]\frac{x}{32}[/tex] so that the 12.5% out of 100 lets us see how many problems 12.5% out of 100% would represents the remaining questions out of 32. so, we would solve for x (x representing the questions left to do after dinner.) So, we would form this equation and solve for x. -->[tex]\frac{12.5}{100} =\frac{x}{32}[/tex]. Now, we would cross multiply, then divide. So we would first multiply 12.5 times 32. This would give us 400. Then, we divide 400 by the 100, which gives us 4, which means that we have 4 problems left to do after dinner.
