Answers

Answer 1

Answer:

2, 10%, 15, 42

Step-by-step explanation:

18 / 9 = 2

Total number of students = 60

6 / 60 = 1/10 or 10%

1/3 ride the bus, so a sample of 45 would give 15

7/60 ride a bike so multiply by 360 = 42

Larry invests $100 in a savings plan. The plan pays 5 1/2% interest each year on
his $100 account balance. The following chart shows the balance on his account
after each year for the next 5 years. He did not make any deposits or
withdrawals during this time.

Answers

Answer:

100*1.055^5 = $130.70

Step-by-step explanation:

the simple way to work this out is to think about how much the savings increase by each year.

Balance * (1+interest)^years

So convert the interest rate to decimals and add it to one. This is the amount the balance is multiplied by each year. Raise it to the power of the years of interest and you get the result.

For 5 years it is

100*1.055^5 = $130.70

A zoo keeper was in charge of determining the population of meerkats at the zoo. He observed the meerkats and noted 8 of them and the special markings are on their face. The next day he went back out and observed the meerkats again. Out of the 20 that he saw, 4 of them were the same meerkats that he saw yesterday. How many meerkats can he assume are living at the zoo?

Answers

Answer:

16

Step-by-step explanation:

The zoo-keeper saw 8 special meerkats the day before and then only saw 4 special meerkats out of 20 the day after so 4 - 20 = 16.

Your answer would simply be 16

A survey of high school students with jobs asked whether the students saved some of the money they earned. 80% of the students said they saved some money. Out of 340 students, predict how many would save some of their earnings.

Answers

Answer:

272

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 340.

Step 2: We represent the unknown value with x or anything you'd like.

Step 3: From step 1 above, 340 in this case would equal 100% as a percent since that's the total value

Step 4: Just a reminder , x=80%

Step 5: This results in a pair of simple equations:

340= 100% (1)

x= 80% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

340/x (340 over x) = 100%/80% (100% over 80%)

Step 7: Again, the reciprocal of both sides gives

x/340 (x over 340) = 80/100 (80 over 100)

x=272$

Therefore, 80% of 340 equals 272

Btw sorry if it's a bit confusing, but the answer is 272.

First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.

A storage box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches.

What is the height of the box?

Answers

The height of the box is 3.5in or 3 1/2in
Ok, so first we need the equation. So we know that v=b*w*h. We know that the base is 4 inches and the width is 4 inches as well. So we get the equation v=4*4*h. The volume is also given so the equation changes to 56=4*4*h. So first we multiply the numbers we have to get 56=16*h. Then we divide 16 on both sides. 56/16 is 3.5. We end up with 3.5=h. So the answer is 3.5 inches. You can also put this back in to make sure it is right. To 56=4*4*3.5 is true. So therefore, the answer is 3.5 inches.
