Answer:

A.)  V = 160π

B.)  V = 502.4 inches^3

Step-by-step explanation:

Part A:

<u>Formula for the volume of a cylinder:  V = π * r^2 * h</u>

r^2 can be broken into r * r

π can be represent by 3.14

It is the same as:  <u>V = r * r * h * 3.14</u>

V = 4 * 4 * 10 * π

V = 160π

Answer:  V = 160π

Part B:  

<u>Step 1:  Plug in</u>

V = 4 * 4 * 10 * 3.14

V = 16 * 31.4

V = 502.4 inches^3

Answer:  V = 502.4 inches^3

Answer:

Step-by-step explanation:

Remark

These two angles are supplementary. They make up the horizontal line. Supplementary angles add to 180 degrees.

Equation

x + 134 = 180

Solution and Answer

x + 134 = 180                    Subtract 134 from both sides

x + 134 - 134 = 180-134    Combine

An aquarium has dimensions 2x feet, (x – 1) feet, and (x + 2) feet. The aquarium volume must be no more than 280 cubic feet.
Lina20 [59]

Answer:

x^3+x^2-2x\leq140

Step-by-step explanation:

This is an algebra problem, and we are expected to inequality for the volume of the aquarium.

Given that the

length= 2x

width=(x – 1)

heigth=  (x + 2)

and the volume= 280 ft^3

the inequality expression for the volume is

2x*(x -1) * (x + 2) \leq 280\\\\

open the brackets

2x*(x -1) * (x + 2) \leq 280\\\\(2x^2-2x)*(x+2)\leq 280\\\\\2x^3+4x^2-2x^2-4x\leq 280\\\\\2x^3+2x^2-4x\leq280

divide through by 2 we have

x^3+x^2-2x\leq140

Which is the more reasonable measurement of the distance between the tracks on a railroad:
nataly862011 [7]

If you're comparing 1.435 * 10^(-3) mm to 1.435 * 10^3 mm, then the more reasonable measurement is 1.435 * 10^3 mm since,

1.435 * 10^3 mm = 1435 mm = 1.435 meters

1 meter is about 3.28 feet approximately

So 1.435 meters is slightly larger (about 4.708 feet) which is a fairly reasonable distance between the tracks on a railroad.

-------------------

Something like 1.435 * 10^(-3) mm is equal to 0.001435 mm, which is far less than 1 mm.
