Can anyone help me out with this question

Answers

Answer 1

Answer:

Step-by-step explanation:

The % itself stands for a ratio of 100, so 70% would be 70/100

Answer 2

Answer:

70/100

Step-by-step explanation:

This is because if you break down a percantage, it is just a fraction or decimal. The numerator is 70 because 70/100 = 0.7

0.7 is just the decimal form of the percent "70%"

Answers

Answer:

Step-by-step explanation:

We know the following:

[tex]OE=5\\\\FG=4\\\\EF=8\\\\[/tex]

so the segment EF is equal to

[tex]EF=EG+GO+OF\\\\[/tex]

and here we can do a trick :)

[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]

you see it's the same

[tex]EF=EO-GO+FG\\\\[/tex]

now we plug the values given

[tex]8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1[/tex]

so it's option A

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?

Answers

Answer:

I think the answer is 171.

Step-by-step explanation:

Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)
