How many centimeters is a piece of paper that measures 12 in​
lakkis [162]
<h2>Hello!</h2>

The answer is:

The piece of paper measures 30.48cm (centimeters)

<h2>Why?</h2>

We need to convert from inches to centimeters, we can do it using the following convertion factor:

1in=2.54cm

Now, calculating we have:

12in*\frac{2.54}{1in}=30.48cm

Hence, we have that the piece of papers measures 30.48cm (centimeters)

HURRY NEED HELP NOW 42 POINTS NEED 1 PARAGRAPH FOR EACH QUESTION there are 2 photos I put up and that where the questions are.
Shtirlitz [24]
1. All you have to do to find the area of the figure. IS first find the area of the rectangle. This is easy because all you have to do is base times height. 

22 x 17 =  374

Now to find the area of the triangle all you have to do is  do base times height like a rectangle, but then divide it by 2 afterwords.
19 x 12 = 228 ÷ 2  = 114.

Now add the two area's together:

374 + 114 = 488.

Just do the same with the one below, I've altered the pic a bit to make it easier.

Given the preimage: A(3, 2), B(3, 6), C(11, 6), D(11, 2). Translate down 4 units. What is B'?
Vilka [71]

Answer:

B' is (3,2)

Step-by-step explanation:

In the original B coordinate pair, 6 is the y-coordinate.  When we talk about shifting images or points up or down, we will normally see a change in the y-coordinate.  In this case, the image is being translated 4 units down, so subtract 4 from 6 to get 2 as your y-ccoordinate for B'.  Since no horizontal shift is being made, the x-coordinate from the original B point stays the same and B' becomes (3,2).
