Solve<span> A = </span>bh<span> for b. Since </span>h<span> is multiplied times b, you must divide both sides by </span>h<span> in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2. Then you have to subtract c from both sides in order to isolate d.</span>

A cylinder has a height of 7 in. and a diameter of 6 in. What is the volume of the cylinder to the nearest cubic inch? V = 66 in

Natalija [7]

Answer:

The answer is

Step-by-step explanation:

Volume of a cylinder = πr²h

where

h is the height

r is the radius

From the question

h = 7 in

To calculate the radius from the diameter we use the formula

radius = diameter/2

From the question

diameter = 6

radius = 6/2 = 3 in

Volume of the cylinder is

(3)²(7)π

= 9(7)π

= 63π

= 197.9203

We have the final answer as

<h3>V = 198 in³ to the nearest cubic inch</h3>

Hope this helps you

Two-thirds of the buses in the transit system run on natural gas, and the rest run on diesel. If 738 of the buses run on diesel,

Sergeu [11.5K]

Answer:

2214 buses

Step-by-step explanation:

Diesel buses constitute 1/3 of the total, so the total number of buses is 3 times the number of diesel buses.

total = 3·738 = 2214

The transit system has 2214 buses.

The graph below shows the cost C for bowling g games at Strike King. Another bowling center, Thunder Alley, charges $2.25 per ga

Lunna [17]

Answer:

They intersect when the Strike king is at (9,15.75) and Thunder Alley is at (7, 15.75). But only the X axes intersect. The X and Y axes intersect at (0,0) that's where they start and that is where they meet. Its a proportional relationship because their ratios are equivalent. It represents the constant of proportionality.
