From the triangles given, ∆ DEF was dilated to ∆ ABC

The dilated triangle is = ∆ ABC

To find the scale factor uses for the dilation of the triangle, the length of the triangle AC and DF are considered.

AC from the scale= -2 -(-7)

= 7-2= 5

DF= 9-6.5

= 2.5

Therefore the scale factor = 5/2.5 = 2

And since the scale factor of dilation is 2 this means that ∆ A' B' C' can be translated to the 0.5 by 2 units.

Answer:

The perimeter is 380 ft^2.

Step-by-step explanation:

To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.

To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.

Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

Answer:

9 days

Step-by-step explanation:

1 day: 5/6        2 days:  10/6       3 days:   15/6        4 days:  20/6   5  days: 25/6

6 days:  30/6        7 days:  35/6         8 days:  40/6       9 days: 45/6

If you divide 45 and 6 by 3 you get 15/2.  If you put 15/2 into a mixed number you would get 7 1/2.  So 9 days would be your answer.

Answer:

7 1/2 bottles will last 9 days

Step-by-step explanation:

To answer this, divide '7 1/2 bottles' by '5/6 bottle per day:"

 7 1/2 bottles

-----------------------

 5/6 bottle/day

The unit "bottle"/"bottles" cancel, and so we are left with

 7 1/2 day

-------------------  and this is equivalent to   15 days/2  divided by 5/6 OR

    5/6

 15 days/2 times 6/5:

15(6)

--------- days = 18/2 days = 9 days (answer)

2(5)

7 1/2 bottles will last 9 days.

The total cost of the cleaning service is $180

Step-by-step explanation:

We have, 30% × x = 54

or,

30/100 × x = 54

Multiplying both sides by 100 and dividing both sides by 30,

we have x = 54 × 100/30

x = 180

If you are using a calculator, simply enter 54×100÷30, which will give you the answer.

Answer: 4 inches

Step-by-step explanation: 1,944 / 18/ 9 / 1/3 = 4

Based on the calculations, the height of this pyramid is equal to: D. 36 inches.

Given the following data:

Mathematically, the volume of a pyramid is calculated by using this formula:

Volume = 1/3 × b × h

Where:

For the base area, we have:

Base area = length × breadth

Base area = 18 × 9

Base area = 162 square inches.

Substituting the given parameters into the formula, we have;

1,944 = 1/3 × 162 × h

1,944 = 54h

h = 1,944/54

Height, h = 36 inches.

Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.

To find x, we can use some facts from geometry and trigonometry.

• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.

• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.

• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.

• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have

tan(70°) = 12 / (x/2)

and solving for x gives

tan(70°) = 24/x

x = 24/tan(70°)

x = 24 cot(70°) ≈ 8.7

Then the total area of the nonagon is

54x = 54 • 24 cot(70°) ≈ 471.7

you get 84.  Then you divide this amongst all of the students.

7+5+7+3+2=24

Answer:

I believe the answer is about 95 percent.

Step-by-step explanation:

The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...

22 1/5 over 100 = 21 over x

Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer

What I just wrote is the rule of proportions

Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.
