Two kindergarteners participated in a fundraiser event "Walk
Backwards for Hunger" last weekend. John walked 2/3 of a mile and Mary
walked 3/4 of a mile. Together, they raised $93.50. How much money, each, did
John and Mary raise? Just so you know, the amount raised is proportional to
distance walked

Answers

Answer:

John = $44   Mary = $49.50

Step-by-step explanation:

2/3 + 3/4 = 17/12

17/12x = 93.5

17/12x x 12 = 93.5 x 12

17x = 1122

17x/17 = 1122/17

x = 66

2/3x = 66 x 2/3

2/3x = 44

3/4x = 66 x 3/4

3/4x = 49.5

44 + 49.5 = 93.5

John earned $44 while Mary earned $49.5.

Answers

Answer:

If 1 inch represents 10 miles on a map, then how many inches will represent
120 miles?

Answers

Answer:

12 inches

Step-by-step explanation:

120/10 * 1 = 12 inches

Answer:

12 inches

Step-by-step explanation:

This question is asking for us to find the amount of inches that is represented to the amount of miles given (120 miles). In order to do this, let's divide the amount of miles that we need to find out for inches, over what information we already have. By dividing 120 over 10, that will give us the amount of inches that 120 miles represents. So:

120 miles / 10 miles = 12 inches.

This is true, because fractions are basically like division. As our example shows, 120 ÷ 10 = 12, which is true.

I hope that this helps.

Answers

Answer:

20,000

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

\

Answer:

the company's total budget is 20,000

Step-by-step explanation:

A company spends 13% of its month budget on rent which total $2600

Let x be the month budget on rent

13% of the month budget is 2600

13% can be written as 13/100

Now we solve for x

multiply both sides by 100

divide both sides by 13

x=20000

So, the company's total budget is 20,000

MF lent $5,000 to Amit on January 01, 2020. (For simplicity, we assume there is no interest.) At the time of loan issuance, MF estimated that $500 of loans receivable would probably be uncollectible, based on their knowledge of historical credit losses.

Answers

From the information given regarding the loan, the amount that will be expected is $4500.

What is an uncollectible loan?

It should be noted that an uncollectible loan or account uncollectible are the receivables or loans that have no chance of being paid.

From the question, the amount lent is $5000 and the uncollectible is $500. Therefore, the amount that will be expected to be collected will be:

= $5000 - $500.

= $4500

In conclusion, $4500 will be expected.

What is the amplitude of the function shown in the graph?

Enter your answer in the box.

Answers

Answer:

1.5

Step-by-step explanation:

Amplitude: the height from the center line to the maximum or minimum point.

We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.

From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5

Therefore, the distance between them = -0.5 - -3.5 = 3

Divide by 2 = 3/2 = 1.5

Therefore, the amplitude = 1.5
