Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15
schepotkina [342]

Answer:

30 to 48, 40/64

Step-by-step explanation:

Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.

For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is <u>equal</u>.

For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are <u>not equal</u>.

For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is <u>equal</u>.

For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is  <u>not equal</u>.

Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it <u>won't be equal.</u>

A software store has put some of its inventory on sale. Games are marked down by 15%, and security programs are marked down by 1
Katyanochek1 [597]

Answer:

Option D. \$11.34

Step-by-step explanation:

Let

x -----> the original price of one game

y ----> the original price of one security programs

Remember that

100\%-15\%=85\%=85\100=0.85

100\%-18\%=82\%=82\100=0.82

The total pay with discount is

\$35.70+\$22.96=\$58.66

we have that

0.85(2x)=35.70\\1.70x=35.70\\x=\$21

0.82y=22.96\\y=\$28

Find the total pay without discount

2x+y=2(21)+28=\$70

The amount saved is the difference

\$70-\$58.66=\$11.34
