can some one help me please what is %75 to $25

Answers

The answer you are looking for is .

To find this answer, you first make 75% into a decimal. To do so, simply divide 75 by 100 to get 0.75. Finally, you multiply 0.75 to 25. This will give you 1875 which you add a decimal point between the 8 and the 7, because .75 has 2 digits behind the decimal (as should the answer. Thus getting 18.75 as an answer. Here's an image to show the multiplication of 0.75 and 25.

Given △ FDR≅△ TGH, what is the value of x? Please make sure to show all your work.

(please help me)

Answers

2x+6=8x-30
(add 30)
2x+36=8x
(subtract 2x)
36=6x
(divide by 6)
6=x

Answer:

x = 6

Step-by-step explanation:

Since triangle FDR is congruent to triangle TGH, you will put them to equal each other and solve for x.

triangle FDR = 2x + 6

triangle TGH = 8x - 30

2x + 6 = 8x - 30

2x + 6 - 6 = 8x - 30 - 6

2x = 8x - 36

2x - 8x = 8x - 8x - 36

-6x = -36

-6x / - 6 = -36 / -6

x = 6

Now that you have find x, we will check if the statement is true that triangle FDR is congruent to triangle TGH. Plug 6 in the x place.

triangle FDR :-

2x + 6

2(6) + 6

12 + 6

18

triangle TGH :-

8x - 30

8(6) - 30

48 - 30

18

So this makes the statement true that triangle FDR is congruent to triangle TGH. Hope this helps, thank you :) !!

3^3-17
and show how you got the answer​

Answers

10

Step-by-step explanation:

3*3 = 9.

9*3 = 27.

27-17 = 10.

Answer:

To solve this problem, we have to remember PEMDAS, which states the order of operations.

We see that we have to simplify the exponents before we add or subtract so we have:

3^3-17

3(3)(3)-17 <-- Remember that 3^3 is equal to 3 times 3 times 3

27-17

10

So, 10 would be your answer.

You are selling candy bars. It cost $140 for

income is based on the fact that you are
selling the candy bars for $4.00 each.

1) What is the profit from selling 40 candy bars? The profit is $ ........

2) What is the profit selling 100 candy bars? The profit is $ .......

3) In order to break even you must sell .......... candy bars.

4) The minimum of candy bars you must sell in order to start making positive profit is .......... candy bars.

Answers

Answer:

Profit = price charged  -  cost of goods

$10  =  Price - 30.00

$40 = Price of one box

So, they have to charge $40 per box. Since there are 50 bars in each box, the price per bar has to be:

$40.00/50 bars = $0.80 per bar

You can check this....

0.80  x  50 bars  = $40.00 <<< this is the total income from the sale of one box.

since each box costs $30.00, they've made $10.00 on each box.
