3: A car travels 120 miles in 3 hours at a steady speed. (a) How far does the car travel in 1 hour? (b) How far does the car travel in 8 hours? How far does the car travel in 1 hour ?


pls give me explanation and working out
thnx :)

Answers

Answer 1

Answer:

The car travels 40 miles per hour. In 8hrs, the car will have droven 320 miles. In one hour the car will have have driven 40 miles. Step-by-step explanation:

Excuse me, but I believe this is a unit rate, so the first thing I did was was divide 120 by 3 to get the answer 40 for A. Then, since I knew that the car goes 40 miles per hour, I multiplied that by 8 to get 320 for B.

Answers

Answer: Look at explanation for the answer please, I am too exhausted to type the answer here

Step-by-step explanation:

y = 10sqrt(5) from the pythagorean theorem

The angle opposing z is arctan(2)

So, find z by the equation

z/y = tan(arctan(2)) = 2

z = 20sqrt(5)

And finally, find x by the pythagorean theorem

x = sqrt(1600) = 40

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.

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.

There are 1213 registered voters in Paul's village. During the last election 887 people actually voted. Which of the following is approximately the ratio of the number of the people who voted to the total number of registered voters in the village?

Answers

Answer:

3 : 4

Step-by-step explanation:

Given:

1213 = total number of registered voters887 = people who voted

ratio of people who voted to total number of registered voters:

To find the approx ratio, round both numbers to the nearest hundred:

887 ≈ 9001213 ≈ 1200

Therefore, 887 : 1213 ≈ 900 : 1200

The greatest common factor of 900 and 1200 is 300,

so we can reduce the ratio further by dividing both sides by 300:

⇒ 900 : 1200 = 3 : 4

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

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.
