Answer:

26

Step-by-step explanation:

W = ∫ f(x) dx

W = ∫₁³ (3x + 7) dx

W = (1.5x² + 7x) |₁³

W = (1.5(3)² + 7(3)) − (1.5(1)² + 7(1))

W = 26

If i have 6 bottles of water and each weigh 3/5 pounds how much do i have
Katen [24]

You have 3 and 3/5 pounds of water.

To find this, simply multiply 3/5 by 6/1 (multiplying straight across). 6 times 3 is 18 and 5 times 1 is 5. Thus meaning you have 18/5 pounds, which simplified is 3 and 3/5 pounds.

I hope this helps!

PLEASE I NEED HELP

Answer: 0.25 feet


Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips=12x=3\ feet

\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
