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.

Answer:

+90°

p(x,y,)=p'(-y,x)

-90°

p(x,y)=p'(y,-x)

180°

p(x,y)=p'(-x,-y)

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).

Answer:

Dilation with scale factor 1/2 = 0.5

Answer:

No.

Step-by-step explanation:

Let's verify that the left-hand-side and -right-hand-side are different, when we replace x by 6:

(6)^2-4=36-4=32

5(6)=30

As 32 is different from 30, then 6 is not a solution of the equation.

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.

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.

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.

Answer:

10h=m or if you not at that math level yet it would times Hx10=M

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)

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.

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.
