Paul's bathtub is clogged. He has to empty 30 liters of water by hand. Paul has a 3-liter, a 4-liter, and a 5-liter bucket. If Paul carries two buckets each trip, what combinations of sizes allow him to empty the bathtub in exactly four trips?

Answers

Answer 1

Answer:

The combinations of sizes allow him to empty the bathtub in exactly four trips is a 5-liter bucket with the 3-liter bucket twice, a 3-liter bucket and the 4-liter bucket.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Paul's bathtub is clogged. He has to empty 30 liters of water by hand.

Paul has a 3-liter, a 4-liter, and a 5-liter bucket.

If Paul carries two buckets each trip, we need to find the combinations of sizes that allow him to empty the bathtub in exactly four trips.

5 and 3 = 8 liters ,

5 and 4 = 9 liters,

3 and 4 = 7 liters.

8 + 7 + 8 + 7 = 30 liters,

So,

He can take the 5-liter bucket with the 3-liter bucket twice, and then he can use the 3-liter bucket and the 4-liter bucket twice.

Answer 2

Answer: 5 and 3 = 8 liters , 5 and 4 = 9 liters, and 3 and 4 = 7 liters.

8 + 7 + 8 + 7 = 30 liters, so he can take the 5 liter bucket with the 3 liter bucket twice, and then use the 3 liter bucket and the 4 liter bucket twice.

why does the multiplication property of equality not allow us to divide both sides of an equation by zero

Answers

Answer:

Yeah, it doesn't...and it won't happen

Step-by-step explanation:

Because dividing with zero isn't a "thing" in math. Let's say you have 12 cookiesbut you're saying you are going to divide among zero people? See? It doesn't even have a real answer because no action happens, but if you said you would split the 12 cookies among 6 people that would means each person would get 2. So multiplying and dividing with zero isn't real math, that's why it doesn't work with equations and math in general.

Which two points have a undefined slope A.(-1, 1) and (1, -1)

B.(-2, 2) and (2,2)

C.(-3, -3) and (-3,3)

D.(-4,-4) and (4, 4)

Answers

Answer:

C.(-3, -3) and (-3,3)

Step-by-step explanation:

When we have a vertical line the slope is undefined.

That means the x values stay the same

C.(-3, -3) and (-3,3)

This has the same x values

m = (y2-y1)/(x2-x1)

=( 3- -3)/(-3 - -3)

(3+3)/(-3+3)

6/0
