What is -1/2 (-5/6 plus 1/3) simplified

Mathematics

Anton [14]3 years ago

Answer:

0.25 or 5/12 - 1/6

Step-by-step explanation:

-1/2(-5/6+1/3), do PMDAS. (-5/6) = -0.833 (repeated) and (1/3) = 0.333 (repeated) and you add them both (-0.833 + 0.333) = -0.5 and -1/2 = -0.5 and when you multiply them both it would equal 0.25. or another explanation for the answer is 5/12 = 0.41666666666 and 1/6 = 0.16666666666 and when you subtract them both you get 0.25, I hope this was helpful.

1. f(x) = x2 - 21<br> f(5)

matrenka [14]

Answer:

x=13

Step-by-step explanation:

if you will substitute the value of f(x) with 5, you will get the following equation:

5=2x-21

2x=26/÷2

x=13

(I didn't know what you ment when you wrote x2, is it x square or 2X)

I really hope it was the second one, cause that's how I solved it.

If you roll two number cubes ,what is the probability of their sum being 9 or higher?

bija089 [108]

Answer:

5/18

Step-by-step explanation:

When two cubes are rolled there are 36 possibilities

Each dice has 6 equally like outcomes so possibilities are

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Now we look at the pair that has sum equal to 9

(3,6) (4,5) (5,4) (6,3) that has sum of 9

Probability of sum is 9 = $\frac{4}{36}$

we look at the pairs that has sum greater than 9

(4,6) (5,5)(5,6) (6,4)(6,5)(6,6)

Probability of sum greater than 9 = $\frac{6}{36}$

Probability of sum 9 or higher = P(sum 9) + P(greater than 9)

= $\frac{4}{36}+\frac{6}{36}= \frac{10}{36}=\frac{5}{18}$

Mr. and Mrs. Parker's bed is 2 1/3 yards wide. That also have 2 nightstands that are 22 inches wide. The bedroom wall is 12 1/2

vampirchik [111]

Conversions: to smallest (inches)
n= 22 inches
b= 2 1/3 yard = 84 inches
t= 12 1/2 feet = 150 inches

total space = t
night stand = n (2n for two nightstands)
bed=b

b+2n has to be < or = to t

84+2(22)=x
84+44=128
128 is < 150

therefore the answer is yes they will fit with 22 inches left over.
