Answer:

Together they can wash  139 windows  in 12 hours

Step-by-step explanation:

t= windows they can  wash together

25/4 +32/6 = t/12

Find common denominator

150/24  + 128/24 = t/12

278/24=t/12

Cross multiplication:

24t = 3,336

Divide both sides by 24

t=139

iris [78.8K]
8\times10^9=2^{12}\times5^9

1) Since in the USA 8 x 10 ^9 messages are sent every month, that means that approximately 8 billion messages are sent.

2) We can Prime factorize it:

Note that on the right side we've picked only prime numbers. In this case, 2 and 5.

So we can rewrite 8 x 10^9 as prime factors.

8\times10^9=2^{12}\times5^9

3) Hence, the answer is:

8\times10^9=2^{12}\times5^9
