Answer:

3

15. 8

Step-by-step explanation:

The man and the son form similar triangles, so the lengths of corresponding sides of the triangles are proportional.

6/8 = x/4

8x = 24

x = 24/8

x = 3

Answer: 3

Question 15

Triangles SCA and STR are similar, so the lengths of corresponding sides are in proportion.

SA + AR = SR

SA + 3 = 9

SA = 6

SA/SR = SC/ST

6/9 = SC/12

2/3 = SC/12

3SC = 2 * 12

3SC = 24

SC = 8

Choose the correct comparison for the numbers below.
Alexandra [31]

Answer:

A

Step-by-step explanation:

In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.

The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.

Since 0.85 is already in decimal form, leave it as it is.

3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:

\frac{3}{4} * \frac{25}{25} = \frac{75}{100}

Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.

91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.

Now that you can see the numbers, just rearrange them from least to greatest

0.75<0.85<0.91

equal to A

Emma has 7 bottles: 3 bottles that contain juice, 2 bottles
UNO [17]

Answer: Out of 7 bottles, 2 bottles contain soda. This means that 2 bottles= 29% out of 100%. 7/2 (7 divided by 2) = 0.285. 0.285 can be rounded up to 0.29, meaning that the approximate percentage of the bottles that contain soda is 29%.

It has two what y equals so idk which one to solve or plug in(...I'm running out of points...)
Virty [35]
Just plug in one of the other (doesn't matter which one) so it will look like
-3x+6=5x+38
or
5x+38=-3x+6 (it's the same thing as the first one)
Then you solve for x and you substitute that value so you can get y.
Hope this helped :)
