Refer to the question below:

irakobra [83]

∛(2x + 5) - 3 = 0
Add 3 to both sides
∛(2x + 5) = 3
Cube both sides
2x + 5 = 27
Subtract 5 from both sides
2x = 22
Divide both sides by 2
x=11
There's your answer. Have an awesome day! :)

a rain gutter is 24 feet long, 4 inches in height, 3 inches at base and 6 inches at top. how many gallons of water will it hold?

Lubov Fominskaja [6]

Answer:1.8701

Step-by-step explanation:

Area (A) of trapezium as marked is = $\frac{1}{2}$ $\left ( sum\ of\ parallel\ sides\right )\times height$

A= $\frac{1}{2}$ $\left ( 3+6\right )\times 4$

A=18 $in^2$

Now for Volume we have to multiply by length because area is same across the length.

volume(v)= $A\times length$

Volume(v)= $18\times 24$

Volume(v)=432 $in^3$

Volume(v)=1.8701 gallon

tangare [24]

The expected value of business profit is the sum of probability times profit:

... 0.2×(-10,000) + 0.4×0 + 0.3×5,000 + 0.1×8,000

... = -2000 + 1500 + 800

... = 300 . . . dollars

The expected value of the business return is slightly positve, so Claire should invest in the business.
