Answer 2

The number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

What is the exponent power with base 10?

To write the big number in short form, we write them in the positive power of 10.

To write the very small number, we write them in the negative power of 10.

Tyler’s math class found that it would take 2.5×10^8 dollar bills to cover a square mile area.

The surface area of the United States is about 3.8×10^6 square miles.

To find the number of dollar bills are needed to cover the United States, we have to multiply 3.8×10^6 square miles with 2.5×10^8 dollar bills.

Let suppose it needed n dollar bills. Thus,

[tex]n=3.8\times10^6\times2.5\times10^8\\n=3.8\times2.5\times10^6\times10^8[/tex]

When the base is same in multiplication operation, add the power. Thus,

[tex]n=3.8\times2.5\times10^6\times10^8\\n=3.8\times2.5\times10^{6+8}\\n=9.5\times10^{14}[/tex]

Thus, the number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

What would be the perimeter of an image if a scale factor of 5 was applied?

Answers

Answer:

Step-by-step explanation:

So first if it was a scale factor 5 you would multiply it by 5 for each side. So for the side of 8 you would multiply it by 5 which is 40 so that side and the other side across from it would also be 40 units. Then for the next one there is 12 units so you do the same 12x5 is equal to 60 so will the one below it.

Then it would be (40 * 2) + (60 * 2)= 80 + 120= 200

So then the perimeter would be 200 units.

First, multiply the length and width each by 5.
12 x 5= 60
8 x 5= 40
For perimeter, add length + length + width + width.
60+60+40+40= 200.
200 ft.

Another way would be to find the perimeter
12+8+12+8= 40
40 x 5= 200
200 ft.

The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?

5.2 ⋅ 107 kilometers
4.7 ⋅ 108 kilometers
5.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers

Answers

Answer:

5.2

Step-by-step explanation:

distance(Mercury, Sun) = 5.8 x 10^7

distance(Venus, Sun) = 1.1 x 10^8

distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7

The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.

This gives us a result of 5.2 x 10^7.

Answer is 5.7 hope that helps

Amber earned $15.50 delivering newspapers on Saturday. On Sunday, he spent $6.95 when he purchased a movie ticket. He needed to borrow money from a friend to complete his purchase of a snack. How much money did Simon pay for the snack if he owes his friend $5?

$ ___________

Answers

Answer: Simon paid $13.55 for the snack.

Plz mark brainliest ;)

Answer:

$13.55

Step-by-step explanation:

ok, so we know that Amber earned $15.50 on saturday and then he spet $6.95 on a movie ticket. so now we need to subtract $6.95 from his orgininal amount which was $15.50.

so $15.50 - $6.95 = $8.55

and then it says that he borrowed money from his friend to purchase a snack and that he now owes $5.00 to his friend so we add the amount of money he had plus the money he now owes his friend.

so $8.55 + $5.00 = $13.55

so in conclution, simon lent amber $5.00 and in total, they paid $13.55 for the snacks.

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 16 minutes of initial set-up time. If it takes 31 minutes to screen-print a batch of shirts, how many shirts are in the batch?

Answers

Answer:

The 16 comes from the fact that we take 16 minutes to set up

Step-by-step explanation:

Answer:

The answer is 5 shirts per batch.

Step-by-step explanation:

If you subtract 16 from 31 you get 15.

And because you make 1 shirt per 3 mins, you can divide 3 from 15 and that would get you to 5.

A mountain road is 5 miles long and gains elevation at a constant rate. After 2 miles, the elevation is 5500 feet above sea level. After 4 miles, the elevation is 6200 feet above sea level.
What would be the equation of this line?

Find the elevation of the road at the point where the road begins.

Describe where you would see the point in part (a) on a graph where represents the elevation in feet and represents the distance along the road in miles.

Answers

Answer:

I hope this helps

Step-by-step explanation:

The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.

A linear equation is in the form:

y = mx + b;

where m is the rate of change, b is the initial value of y and y, x are variables.

Let y represent the elevation of the road after x miles.

After 2 miles, the elevation is 5500 feet above sea level. Hence:

5500 = 2m + b (1)

After 4 miles, the elevation is 6200 feet above sea level. Hence:

6200 = 4m + b (2)

Solving equation 1 and 2 simultaneously gives:

m = 350, b = 4800

The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.

Step-by-step explanation:

Answer:

m = 9h

Step-by-step explanation:

you can see that in 5 hours she earns 45 dollars

divide 5 hours by 5 and 45 dollars also by 5

you then find that in 1 hour she earns 9 dollars

so in h hours she earns 9 times h

which is h = 9h

but in this case it asks for money so it is m = 9h (h is how much hours she worked)

Paloma draws triangle ABC on a grid. She applies a rule to make the

Answers

Answer: Dilation with scale factor 1/2 = 0.5

===========================================

Explanation:

The image is not the same size as the preimage. This means a dilation has occurred. Specifically, the image has been shrunk. The scale factor k must be in the interval 0 < k < 1.

-----------

Point B is at (2,2)

It then moves to (1,1)

The scale factor is 1/2 = 0.5

To find the scale factor, you divide the image x coordinate over the preimage x coordinate.

So the triangle is now half as tall and wide compared to from before.

Point A is the center of dilation. The origin is often the default center. The center of dilation is the only point that doesn't move (fixed point).

Dilation with scale factor 1/2 = 0.5
