30 in each bus. 17 in each van

To solve this problem, we first have to create a system of equations. After that, you set the equations equal to each other, and use that to simplify and find the value of one variable. Once that is found that answer can be plugged into one of the two original equations to find the other variable.

Draw the image of the figure with the given vertices under a dilation with the given scale factor centered at the origin j(-2,2)
Elenna [48]

Answer:

See Attachment.

Step-by-step explanation:

To create the new figure, we must multiply each coordinate by the scale factor, which is 1/2 in this case.

So j(-2,2) becomes j'(-1,1)

K(4,2) becomes K'(2,1)

L(4,-2) becomes L'(2,-1)

and M (-2,-2) becomes M'(-1,-1)

The scale factor is between 1 and 0 which means that this dilation is a reduction that will shrink the original figure to a smaller one.

A sweater is marked 30% off during an end or season sale. If the sweater was originally $56.00, what is the sale price of the sw
Ludmilka [50]

Answer:

Sweater costs 56.00

To calculate the discounted price of the sweater

56 * (30/100) = 16.8

We used (30/100) to find out the 30 percent of the sweater which will be on discount/reduced.

56-16.8=39.2 is the discounted price

Then we subtract the amount of discount from the original price of sweater to find out the discounted price.

Make six prime numbers using the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 once each.
lana [24]

Answer:

2, 3, 5, 7, 11, 13.

Step-by-step explanation:

A prime number is a number that you don't get a whole number when divided by 2 but you do get a whole number when divided by prime numbers such as 3,5,7,11... Basically a number with two factors, it can only be divided by 1 or themselves. for example:

9/2 = 4.5 (this is not a whole number so it might be a prime.

9/3 = 3 (it works when divided by a prime number.

another:

8/2 = 4 (it gives a whole number when divided by 2 therefor, it can't be a prime number.

Answering:

There are 6 prime numbers at the top^^^^.
