Uncle percy sold t-shirts at the show. Now he only have 10% of the t-shirts he started with. If he has 25 t-shirts now, how many

Nikitich [7]

Percy used to have 100% of the shirts (before he started selling them). Since then, he has given away 90% of the shirts and is now left with only 10% of what he used to have. He currently has 25 shirts, meaning that 25 is 10% of what he had.

Lets set up a proportion:

25 shirts : 10%
x shirts : 100%

x = 25*100 / 10
x = 2500 / 10
x = 250 shirts
Percy started off with 250 shirts.

Joan waters her plants each day with gallons of water. With a new irrigation system in place, she uses gallons of water each day

vampirchik [111]

Answer:

$172\frac{1}{2}$ gallons

Step-by-step explanation:

Considering she waters her plants with 25 1/2 gallons i.e 51/2

and with the new system, she does it with 19 3/4 i.e 79/4

taking the difference:

$\frac{51}{2} - \frac{70}{4}$ = $\frac{23}{4}$ gallons per day

For 30 days:

30 x $\frac{23}{4}$ = 172.5 or $172\frac{1}{2}$ gallons

A farmer wants to plant peas and carrots on no more than 400 acres of his farm. If x represents the number of acres of peas and

levacccp [35]

Answer:

Step-by-step explanation:

It doesn't make sense for either x or y to be negative because we are talking about x representing the number of acres and y representing another number of acres and that they should add up to no more than 400.

So I'm not going to look at A or C.

B looks good 250+150=400

D almost looks good 1+400=401; the problem with this answer is that is more than 400

Parker has a part-time job picking apples. Let the random variable A represent the number of baskets of apples picked each day.

makkiz [27]

Answer:

The correct answer is B. μ = US$87.50 and σ = US$6.50

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of baskets of apples picked each day by Parker = A

Mean of A = 4.5 baskets

Standard deviation = 1.3 baskets

Daily payment received by Parker = US$ 65 + US$ 5 per basket

2. What are the mean μ and standard deviation σ of Parker’s daily pay?

Let's find out the mean and standard deviation of Parker's daily pay:

Daily payment received by Parker = US$ 65 + US$ 5 per basket

Daily payment mean received by Parker = 65 + 5 * 4.5

Daily payment mean received by Parker = 87.5

Standard deviation in US$ = 1.3 * 5

Standard deviation in US$ = 6.5

The correct answer is B. μ = US$87.50 and σ = US$6.50
