Daniel [21]

Answer:

The volume of diamond is 20 cubic inches.

Step-by-step explanation:

We are given the following in the question:

Triangular base:

Base = 4 inches

Height = 5 inches

Height  of the pyramid = 6 inches

Area of triangular base =

A = \dfrac{1}{2}\times \text{Base}\times \text{Height}\\\\A = \dfrac{1}{2}\times 4\times 5\\\\A = 10\text{ square inches}

Volume of diamond = Volume of pyramid

V=\dfrac{1}{3}\times \text{Area of triangular base}\times \text{Height}\\\\V=\dfrac{1}{3}\times 10\times 6\\\\V = 20\text{ cubic inches}

Thus, the volume of diamond is 20 cubic inches.

Suppose your car gets 28 miles per gallon of gasoline, and you are driving at 55 miles per hour. Using unit analysis, find the a
pentagon [3]
<h3>Answer:</h3>

1 27/28 ≈ 1.964 gallons/hour

<h3>Step-by-step explanation:</h3>

You want gallons in the numerator of your unit rate, but that unit is in the denominator of the mileage rate. So, the computation must involve division by 28 mpg. Hours is already in the denominator of 55 mph, so the computation will involve multiplication by that rate.

... (55 mi/h)/(28 mi/gal) = (55 mi/h)·(1 gal/(28 mi)) = 55/28 gal/h

... = 1 27/28 gal/h
