10. 4:5....added = 9
     4/9 (1800) = 7200/9 = 800 (red)
     5/9 (1800) = 9000/9 = 1000 (green)
     there were (1000 - 800) = 200 less red ones then green ones.

11. 7/4 = 21/r
      cross multiply
      (7)(r) = (4)(21)
      7r = 84
       r = 84/7
       r = 12....Rod has 12 stickers

12. 14/4 = 3.5 eggs per cup
      for 16 cups...16 * 3.5 = 56 eggs

It cost Allison $5.80 to send 58 text messages. How much would it cost to send 40 text messages?
Vitek1552 [10]

Answer:

4$

Step-by-step explanation:
The ratio between the $5.80 spent for 58 text messages is $0.10. This means that each text message sent is $0.10. So you just multiply $0.10 and 40 text messages to find that it costs $4 to send 40 messages.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
strojnjashka [21]

Answer:

P(X = 3) = 0.14680064

Step-by-step explanation:

Formula=============================

p\left( X=k\right)  =C^{k}_{n}p^{k}(1-p)^{n-k}\ \ ;\ k\in \left\{ 0,\ldots ,n\right\}

……………………………………………………………………..

Given :

n = 8

p = 0.2

1 - p = 1 - 0.2 = 0.8

k = 3

Then

p\left( X=3\right)  =C^{3}_{8}(0.2)^{3}(0.8)^{5}

               =0.14680064

Factor each linear expression.if expression can not be factored write cannot be factored.<br> 36x-9
almond37 [142]

Answer:

9(4x - 1)

Step-by-step explanation:

The given linear expression is:

36x - 9

Since, 36 can be written as 9 times 4, we can rewrite the above expression as:

9(4x) - 9

Taking 9 as common, the expression changes to:

9 (4x - 1)

This linear expression can no linger be factorized further.

So,

36x - 9 = 9(4x - 1)

I needddd helppp please
Montano1993 [528]

Answer:

X=66°

Step-by-step explanation:

Because it is an isosceles triangle, the 2 missing angles are going to be the same size.

Subtract  48 from the total degree of the triangle which is 180.

180-48= 132

now you di ed that by 2 and you’ll know the missing angle.

132/2= 66
