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

Find how cookies eats Mailyn in one minute

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

Find how cookies eats Juan in one minute

by proportion

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

3) Find how long will it take them to eat 40 cookies together

we know that

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

by proportion

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

therefore

the answer is

$56.34\ minutes$

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.
