Radda [10]

Answer:

It takes 32 Minutes for 12 people to paint 12 walls

The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27

Joey had 40 words to study for a spelling quiz, but he only learned 10 of them. His teacher surprised the class by telling them

Natasha2012 [34]

Answer:

The probability of choosing a word randomly which is one of the words Joey learned = 1/4

Step-by-step explanation:

Total number of words to be memorized = 40 words

The number of words memorized by Joey = 10

Let E: Event of randomly choosing a word that Joey has learned.

P(E) = $\frac{\textrm{The total words learned by Joey}}{\textrm{Total Words in the quiz}}$

$\implies P(E) = \frac{10}{40} = \frac{1}{4}$

Hence, the probability of choosing a word randomly which is one of the words Joey learned = 1/4

I added 3/4 + 1/5 and got 4/9 " does it make sense?

masya89 [10]

<h3 /><h3> $\frac{3}{4} + \frac{1}{5} = \frac{4}{9} \\ \frac{3 \times 5}{4 \times 5} + \frac{1 \times 4}{5 \times 4} = \frac{4}{9} \\ \frac{15 + 4}{20} = \frac{4}{9} \\ \frac{19}{20} ≠ \frac{4}{9}$ </h3>

THIS SHOWS THAT YOUR ANSWER IS NOT CORRECT.
