Help I don't know what to choose
Lunna [17]

Answer:

Step-by-step explanation:

We know a triangle adds up to 180 so:

75+36+ ? = 180

111+ ? =180

? = 69

To find out x, we know that a straight line adds up to 180 so again:

x +69 = 180

x = 111

Shona is buying a rug for her room. Store A has the rug for $45 with a 10% discount. Store B has the same rug for $46 and is off
Rudik [331]
Store A :
0.90(45) = 40.50......40.50 + .06(40.50) = 40.50 + 2.43 = 42.93

store B :
46 - 10 = 36......36 * .06(36) = 36 + 2.16 = 38.16

she would have to purchase the rug from store B...because she doesn't have enough money to purchase it from store A. She would have (40 - 38.16) = $ 1.84 in change.

I find this question to be a little misleading....because on a rebate, u dont get the discount right away....u first pay full price, and then later u get the discount mailed back to you. So actually, she wouldn't have enough money at either store.

How do you simplify the square root of 48
noname [10]
When you simplify the square root of a number, you are looking for factors of the number that are perfect squares that you can remove from under the radical.  For example sq root of 8... it's not a perfect square but factors of 8 include 2 x 4... 4 is a perfect square so we can take it out of the radical by taking it's square root.  Now you are left with 2* sq root of 2.

For sq root of 48

48 = 12 x 4 

12 = 3x4  so we can say 48 = 3x4x4

so... sq root 48 = sq root 3x4x4

we have two 4's under the radical.  Sq root x^2 = x    so sq root 4^2 is 4

Pull it out from the radical and we are left with 4 * sq root 3

The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
