Answer:
$0.5
Step-by-step explanation:
formula ; y = kx
where ; y = $1.5
x = 3 pounds of bananas
k = constant of proportionality
Step 1. Do the equation based on the data given
y = kx
$1.5 = k3
Step 2. Compute the mathematical equation. Divide both sides by the coefficient of 3.
<u>$1.5</u> = <u>k3</u>
3 3
k = .5
Answer; $0.5 is the constant of proportionality cost in dollars per pound of banana.

Answer:
6-10b
Step-by-step explanation:
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

2) Juan needs 3 hours to eat 32 cookies
<u>Find how cookies eats Juan in one minute</u>
by proportion

<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

therefore
<u>the answer is</u>

Answer:
A Yes
Step-by-step explanation:
the ratio is 2:1
