<h3>Answer: -4</h3>

Explanation:

Move the decimal point to the right one spot for each value

-3.2 turns into -32

0.8 turns into 8.0 which is the same as 8

That means the given fraction is the same as -32/8 which simplifies into -4

Answer:

Your answer is 306 units^2!

Step-by-step explanation:

Let's work this out together!

First let's find the top and bottom square's area.

6 x 15 = 90

Since there are not only two of those shapes but THREE, 90 x 3= 270.

So 270 is the surface area of the middle rectangles.

Step 2! Let's find the area of these triangles. We know that both of the triangles are 6 on each side.

Think back to geometry formulas. The formula for finding the area of a triangle is different then a square.

Triangle formula: Base x Height / 2 = A

Rectangle formula: Base x Height = A

So 6 x 6 is 36, now we have to divide it by two; which equals 18.

Since there are TWO triangles, we multiply 18 by two giving us the total surface area of the triangles, 36.

Now let's add our products together!

36 + 270 = 306

Thus the total surface area being 306 units^2

Last one lol Thx for helping if u do

The answer is A.

We know that p must be larger than d since a discount means something will be cheaper. Then we know that $2.50 is essentially what p-d should equal to (p-d =2.50)

Then you work through the various tables and find which values will consistently give you 2.50 as the difference between p and d.

For example in table A:

3.00-0.15=2.50
4.00-1.50=2.50
5.00-2.50=2.50
6.00-3.50=2.50

A girl's feet are negative 4 over 5 yards from the surface of a pool. A boy's feet are negative 2 over 5 yards from the surface

ANTONII [103]

There are many ways you can do this. To me, the easiest way is cross multiplying, but since the denominators are the same, there is no need to do that. Also, the fractions are negatives, the one closest to 0 is closer to the surface of the pool
-4/5 = -2/5 in this case -2/5 is closer to the surface of the pool.

Answer: the boy's feet are closer to the surface of the pool

a couch ,a love seat,and a chair cost $1565.the couch costs twice as much as the chair,and the love seat costs $ 400 more than t

Art [367]

I'm guessing you are having a problem with translating the problem into an equation you can solve. To help this what you can first do is underline the important parts of this problem. twice as much, 400 more,
Lets look at this
First Let the chair=x
Next we know the couch cost twice as much as the chair
So now we know we should let the couch=2x
Lastly the love seat is 400 more than the couch. couch+400is the same thing as saying 2x+400
NOw 1565=chair(x)+couch(2x)+love seat(2x+400)
So that means 1565=x+2x+2x+400
Combine like terms and you now have 1565=5x+400
Now you isolate the variable by subtracting 400 from both sides which is 1165=5x Then you divide both sides by 5 and get 223=x
