         (45 gal/day) x (31 day/Dec) =

               (45 x 31) (gal/Dec) = 1395 gallons per December .

Choice-B is closer to that figure than Choice-A is,
but they're both poor estimates.

 to add fractions you need the denominators to be the same, so you multiply the values in the fractions to get a denominator of 6.--> 4/6+3/6. 
Then we add the numerators.--> 7/6. 
Then we simplify 7/6, which is 1 1/6.

QUESTION POSTED AT 06/12/2019 - 01:17 PM

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November. What is the new class average for number of siblings? Round your answer to the nearest hundredth.

Answer: The new class average for number of siblings is 3.19

Initially the number of students was 25:
n1=25
And the average number of siblings for each student is 3
avg1=3
avg1=T1/n1
where the total number of siblings: T1
Replacing in the equation of avg1 the known values:
3=T1/25
Then, we can solve for T1: Multiplyng both sides of the equation by 25:
25(3)=25(T1/25)
75=T1
T1=75
Initially the total number of siblings was 75

A new student with 8 siblings joins the class in November:
The number of students will be: n2=n1+1=25+1→n2=26
And the total number of siblings will be: T2=T1+8=75+8→T2=83

What is the new class average for number of siblings? Round your answer to the nearest hundreth:
avg2=T2/n2=83/26=3.192307692
Rounded to the nearest hundreth:
avg2=3.19

Answer: The new class average for number of siblings is 3.19

What is 45 1/2% as a fraction in simplest form?

 For this case we have the following expression:
 45 1/2%
 Rewriting in decimal form we have:
 45.5%
 Then, the percentage in its numerical and decimal form is:
 45.5 * (1/100) = 0.455 

 We now write the decimal in the form of a fraction.
 We have then:
 0.455 * (1000/1000) = 455/1000 

 Simplifying the fraction we have:
 (455/1000) * ((1/5) / (1/5)) = 91/200 

 Answer:
 The expression given in the form of fraction is:
 91/200

A used automobile dealership recently reduced the price of a used compact car by 6%. If the price of the car before discount was 18,400, find the discount and the new price

Answer:  Discount Price = $1104

New Price = $17296

Step-by-step explanation:

Given : A used automobile dealership recently reduced the price of a used compact car by 6%, which can be written as 0.06.

The price of the car before discount was 18,400.

Formula for Discount = Discount percentage× Original price

Then , Discount =0.06\times18400=\$1104

New Price after Discount = Original Price - Discount price

=\$18,400-\$1104=\$17296

Hence, Discount Price = $1104

New Price = $17296

In a class of 24 students 13 students sold over 150 raffle tickets each and the rest of the class sold about 60 raffle tickets each. The class goal was to sell 2000 tickets. Did they reach their goal? Explain.

Yes. 
First we need to find out what the number of the rest of the class is. 24-13 is 11. So since 13 kids sold 150 each, we would need to multiply them, that would give us 1950. Then we need to find out the total of the 11 kids that sold 60 each. 60 times 11 is 660. Then we need to add 1950 and 660. That gives us 2610 tickets. That is more than 2000, so they reach their goal.

QUESTION POSTED AT 06/12/2019 - 11:27 AM

Most Americans throw away about 1,365 pounds of trash each year. Is it reasonable to estimate that Americans throw away over 10,000 pounds of trash in 5 years? Explain.

The correct answer is:

No it is not.

Explanation:

Since the average amount thrown away per year is 1,365, to estimate we can round. 1365 would round to 1000, or if we were estimating high, we could use 1500, since it is close.

1000(5) = 5000 in 5 years' time;

1500(5) = 7500 in 5 years' time.

To have an estimate of over 10,000 in 5 years' time, we would need a number that would round to 2000. 1365 is nowhere near 2000, so our estimate would not be that high.

A circular swimming pool holds 1.22 x 10^6 cubic inches of water. It is being filled at a rate of 1.5 x 10^3 cubic inches per minute. How many hours will it take to fill the swimming pool?

You can set up a proportion:
1.5*10^3/1=1.22*10^6/x
Cross multiply:
1.22*10^6=1.5*10^3x
Solve for x:
x=(1.22*10^6)/(1.5*10^3)
x≈813.33
Now, Divide 813.33 by 60 because the question asks for hours, not minutes:
813.33/60≈13.56
So it will take approximately 13.56 hours for them to finish filling up the swimming pool.
