Is 3/12 less than 2/3

2 answers:

8 0

Yes, because 3/12 can ne simplified to 1/4 and one fourth is less than 2/3 so therefore 3/12 is less than 2/3. Think of it as a pizza, if you cut the pizza into twelve pieces and eat three and then you take another pizza and cut it into three pieces and eat two, which pizza has less eaten?

Well, when you simplify 3/12 it equals 1/4 so if you multiply that by 3 and multiply 2/3 by 4 to get common denominators, you have 3/12 and 8/12, so yes, 3/12 is less than 2/3. I hope this helps cx

An aerodynamic three-wheeled automobile (the Dart) runs on compressed natural gas stored in two cylinders in the rear of the veh

pogonyaev

Answer:

a) 7702.88 miles

b) If we drive more than 7702.88 miles per year, the dart would be more economical.

Step-by-step explanation:

Assuming a useful life of 7 years.

Let's calculate EUAC dart:

(15000)(A/P, 10%, 7) + (X/100mpg)(8)

= 15000 * 0.2054 + 0.08

= 3081.15 + 0.08X

EUAC For other automobile:

(12000)(A/P, 10%, 7) + (X/50mpg)(8)

= 12000 * 0.2054 + 0.16X

= 2464.92 + 0.16X

a) To solve for X, we have:

EUAC dart = EUAC other automobile

3081.15 + 0.08X = 2464.92 + 0.16X

0.08X - 0.16X = 2464.92 - 3081.15

-0.08X = - 616.23

X = 7702.88 miles

b) The range of annual miles driven is the Dart more economical.

EUAC dart < EUAC other automobile

3081.15 + 0.08X < 2464.92 + 0.16X

X > 7702.88 miles

If we drive more than 7702.88 miles per year, the dart would be more economical.

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface

never [62]

Answer:

$2\sqrt{2}\ ft\ longer$

Step-by-step explanation:

Suppose a cube with side length s, the area of one side is

$A_s=s^2$

Since the cube has 6 sides, the total area is

$A=6A_s=6s^2$

But if we have the area, we can solve the above formula for s to get

$A=6s^2$

$\displaystyle s=\sqrt{\frac{A}{6}}$

We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths

$\displaystyle s_1=\sqrt{\frac{1,200}{6}}=\sqrt{200}$

$\displaystyle s_1=10\sqrt{2}\ ft$

$\displaystyle s_2=\sqrt{\frac{768}{6}}=\sqrt{128}$

$\displaystyle s_2=8\sqrt{2} ft$

The difference between them is

$10\sqrt{2}\ ft-8\sqrt{2}\ ft=2\sqrt{2}\ ft\approx 2.83\ ft$

The side of the cube with area 1,200 square inches is $2\sqrt{2}\ ft$ longer then the side of the cube with area 768 square inches

What is the volume of the metal in this heavy-duty pipe? (It is not drawn to scale and the inside of the pipe is empty space.) S

Jlenok [28]

The volume of the pipe is about 282.6 cubic feet.

First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).

pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7

The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6

You are asked to calculate gas mileage for a car, and your answer comes out with units of gal/mi. This means that

Lynna [10]

If you were to calculate the gas mileage of your car and the answer turns out to be in units of gallons per mile, then that simply means your car uses a gallon of gas per mile. So for every one mile of traveling on the road that you do, you would make use of an entire gallon. This is the standard unit of measuring gas (also known as MPG). If you have a lower amount, then that means your car uses less gallons per mile which means that it is more fuel efficient. The opposite can be said for when it is higher.
