The ratio of girls to boys would be  16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)

After a 15% price reduction, a boat sold for $15,200. what was the boats price before the reduction?
lora16 [44]

Given that after a 15% price reduction, a boat sold for $15,200. Now we have to find the boats price before the reduction.

Let the boats price before the reduction = x

Reduction = 15% of original price = 15% of x = 0.15x

Then selling price will be difference of original price and reduction

Selling price = Origina price - Reduction

15200 = x - 0.15x

15200 = 0.85x

\frac{15200}{0.85}=x

17882.3529412=x

Hence origina price before reduction is approx $17882.35

Find the ratio of cans of fruit to the total number of food items collected.
Butoxors [25]
First add all the items together:

6 + 4 + 7 + 4 = 21

then we compare 6 and 21 and look for common factors, 6 and 21 have the common factor 3 so we divide them both by 3 to get 2 and 7. since 2 and 7 have no common factors our answer is

2:7

This means for every 2 cans of fruit there are 7 total items and vice versa.

If 80% of M is equal to 50% of N and N≠0, what is N M equal to?
asambeis [7]

Answer:

0.625N

Step-by-step explanation:

                                        0.50N

0.80M = 0.50N, so M = ------------

                                          0.80

and so:

                0.50N

N*M = N*------------ = (5/8)N, or 0.625N

                   0.80

Find the measure of ZB.
RoseWind [281]

The sum of the inside angles of a triangle, always sum up to 180 degrees. Using this information, we can create the following equation for this problem:

(3x-2)\text{ +(6}x\text{+11)+(5}x\text{ +3) = 180}

Adding up all terms with 'x' and adding the other together, we have the following equation:

\begin{gathered} (3x+6x+5x)+(11+3-2)=180_{} \\ 14x+12=180 \\ 14x=180-12=168 \end{gathered}

Solving this last equation for 'x', we have the following:

\begin{gathered} 14x=168 \\ x=\frac{168}{14}=12 \end{gathered}

Then, the final answer for the 'x' value is twelve!
