You can reflect a square onto itself across ___ different lines of reflection.

1 answer:

8 0

The answer is c because if you have a square and you look at a reflection you can see that a square has 4 sides so if you look at the reflection you would see another of the square. So what you would do is 4+4 which equals to 8.

I would say solve each diameter equation and order them fromleast to greatest, for example

1 Venus- 7.52×10 to the power of 3
So first simplify 10 to the power of 3 which is, 1000. Then you multiply 7.52 by 1000 which gets you 7520.

So solve each equation and order it

Answer:

8/15

Step-by-step explanation:

you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1

then you multiply across

2/15 * 4/1

you first multiply 2 and 4 and your answer will be 8 which is the numerator

then multiply 15 and 1 which is 15, the denominator

then you get

Your next math test is worth 111 points and contains 32 problems. Each problem is worth either 4 points or 3 points. How many 3

Dafna11 [192]

We call x the 4 points-worth problems and y the 3 points-worth problems

You know that x+y = 32

4x+3y = 111

You know that the difference from the x and y is 32 so write:

x = 32-y

Substitute at x the value of 32-y

4(32-y)+3y = 111

128-4y +3y = 111

-4y+3y = 111-128

-y = -17

y = 17
