I need help understanding this homework. I am totally lost. It says Solve the problem, show your work and PQPA your answer. My daughter has to turn this paper in tomorrow morning.

Answer 1

Answer:

Step-by-step explanation:

I'm guessing that "PQPA" means like Problem Question, Problem Answer (so what you are trying to find, and what it is (I think)).

That means the first problem is (3/4)+(7/8) = 13/8 and "How much water is collected in two hours?"

This means the second problem is (2 1/3) - (1 3/4) = (7/3)-(7/4) = 7/12 and "How many pounds of beef are left"

This means the third problem is (1 -(1/6))(2/5) = (5/6)(2/5) = 1/3 and "What fraction of her paycheck is saved"

This means that the fourth problem is (3/4)(2/3) = 1/2 and "How long did it take Megan to do her HW?"

how do you do percent proportions? I'm learning those right now, and I have no idea what to do. my teacher isn't the best at explaining things. an example of what I don't get is "4% of what number is 10?" also things such as "16 is what percent of 64?"

Answers

Remember these tips:

=> To turn apercent into a decimal, move the decimal point 2 places to the left.
4%means 0.04 , and 50% means 0.5 .

=> To turn a decimal into percent, movethe point 2 places to the right.
0.062 means 6.2% .

=> Inmath, whenever you see the word "of", it almost always means "times".
So your 2nd example means

16 = (mystery number) x (64).

Divide eachside by 64 : 16/64 = mystery number = 1/4 = 0.25 .

Move the point 2places to the right. 0.25 = 25% .

Artificial turf in on athletic fields was first introduced in the 1960s. Its safety has been controversial since then. One issue that has been investigated is whether injuries of football players tend to be more serious on artificial turf than grass. A study followed 24 NCAA division 1A college football teams over three seasonsIn total there were 1050 injuries that occurred on field turf. Of the field turf injuries, 83.3333% were minor and 10.857% were substantial.

77.972% of grass injuries were minor.

4.26% of injuries occurred on grass were severe.

(There is a total of minor injuries on grass and on field turf is equal to 1813.

How many injuries were severe and occurred on field turf? Write your answer as an integer.

How many injuries were severe? Write your answer as an integer.

Answers

1. Out of 1050 injuries that occurred on field turf:
$(1050)(0.8333) = 875$ were minor and $(1050)(0.10857) = 114$ were substantial. This leaves 1050 - 875 - 114 = 61 severe injuries.

2. If there were 1813 total minor injuries, and 875 were on field turf, then 1813 - 875 = 938 were on grass. This is 77.972% of all grass injuries, so $0.77972x = 938$ gives $x = 1203$ total grass injuries.

Since 4.26% of grass injuries were severe, this is (1203)(0.0426) = 51 severe grass injuries. Adding this to the 61 severe turf injuries gives a total of 112 severe injuries.
