Answer:

1\frac{1}{4}\ liters

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

1\frac{3}{5}=\frac{1*5+3}{5}=\frac{8}{5}

step 2

Using proportion

\frac{2}{(8/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=2/(8/5)\\ \\x=10/8\ liters

step 3

Convert to mixed number

\frac{10}{8}\ liters=\frac{8}{8}+\frac{2}{8}=1\frac{1}{4}\ liters

What is P(A and B)?
Wittaler [7]

Answer: the fraction 3/7

=====================================================

Explanation:

We have 7 places: India, Tokyo, Houston, Peru, New York, Tijuana, Canada

Out of these 7 places, 3 of them are both a city and in North America. Those three places are: Houston, New York, Tijuana

We divide the two values (smaller over larger) to get the final answer 3/7

writing P(A and B) is shorthand for asking for the probability of getting a city AND that place is also in north america as well.

PLEASE HELP! WHOEVER ANSWERS FIRST AND EXPLAINS IS BRAINIEST!!!
inna [77]

Answer:

The answer is A

Step-by-step explanation:

Writing the equation, it would look like (4/5) divided by (3/8) which gives you the answer 2 2/15 which is a mixed number btw. Only two of the answers uses this number, either A or C. C doesn't make any sense because the question already states that Sean has 4/5 pounds of honey. A makes sense because technically what you are doing is dividing the amount of honey Sean got into groups each holding 3/8 pounds.
