Answer:

C. log 10m is the correct answer.

Step-by-step explanation:

The laws of logarithm states that if you have:

log(a)  +  log(b )  =  log(a \times b)  =  log(ab)

So, comparing that to your question,

log(m)  +  log(10)  =  log(10m) .

Mailyn loves cookies. She can eat 32 in an hour. Her brother Juan, however, needs 3 hours to eat the same amount of cookies. How
bezimeni [28]

we know that

1) Mailyn can eat 32 cookies in an hour

1 hour  is equal to 60 minutes

<u>Find how cookies eats Mailyn in one minute</u>

by proportion

\frac{32}{60} \frac{cookies}{minutes}= \frac{x}{1} \frac{cookie}{minutes} \\\\ x=32/60\\x=0.53 \ cookies

2) Juan needs 3 hours to eat 32 cookies

<u>Find how cookies eats Juan in one minute</u>

by proportion

\frac{32}{180} \frac{cookies}{minutes}= \frac{x}{1} \frac{cookie}{minutes} \\\\x=32/180 \\x=0.18\ cookies

<u>3) Find how long will it take them to eat 40 cookies together</u>

we know that

Maylin and Juan eats in one minute together ---------> (0.53+0.18)=0.71 cookies

so

by proportion

\frac{0.71}{1} \frac{cookies}{minutes}= \frac{40}{x} \frac{cookie}{minutes} \\\\0.71*x=40\\x=56.34 \ minutes

therefore

<u>the answer is</u>

56.34\ minutes
