A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The amount of paint needed to paint 20 pillars is 9.874 gallons.

<h3>What is a cylinder?</h3>

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

The curved surface area of a single-cylinder with a diameter of 2.5 feet and a height of 22 feet will be,

Curved surface area = πDh = π × 2.5 × 22 = 172.7875 ft²

The total area of 20 pillar = 20 × 172.7875 ft² = 3,455.75191 ft²

Since a gallon of paint can cover only 350 ft², therefore, the amount of paint that will be needed to paint 3,455.75191 ft² can be written as,

$\text{Amount of paint needed} = \dfrac{3,455.75191\rm\ ft^2}{350\rm\ ft^2} = 9.874\rm\ gallons$

Hence, the amount of paint needed to paint 20 pillars is 9.874 gallons.

We compute the productivity percentage change of each category using the formula:

$\text{\% Change }=\frac{\text{ Value now - Value last year}}{\text{Value last year}}\cdot100\%.$

Productivity percentage change for each category

1) Units produced:

$\frac{1,000-1,000}{1,000}\cdot100\%=0\cdot100\%=0\%.$

2) Last (hours)

$\frac{275-300}{300}\cdot100\%=-\frac{25}{300}\cdot100\%=-8.33\%.$

3) Resin (pounded)

$\frac{45-50}{50}\cdot100\%=-\frac{5}{50}\cdot100\%=-10\%.$

4) Capital invested ($)

$\frac{11,000-10,000}{10,000}\cdot100\%=\frac{1,000}{10,000}\cdot100\%=10\%.$

5) Energy (BTU)

$\frac{2,850-3,000}{3,000}\cdot100\%=\frac{-150}{3,000}\cdot100\%=-5\%.$

2) Improvement for labour hours

From the previous computations, we see that the percentage change of the category "Last (hours)" has a negative value of -8.33%, which means that this value decreased by 8.33% with respect to the last year.

Answer

1) Productivity percentage change for each category

0. Units produced: ,0%

,

1. Last (hours): , -8.33%

,

2. Resin (pounded):, -10%

,

3. Capital invested ($): ,10%

,

4. Energy (BTU): ,-5%

2) Improvement for labour hours

The percentage change of the category "Last (hours)" has a negative value of -8.33%, which means that this value decreased by 8.33% with respect to the last year.

Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in s

Usimov [2.4K]

Answer:

y = -1/2x + 1/2

Step-by-step explanation:

perpendicular lines have slopes that are opposite signs and reciprocal

therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)

-4 = -1/2(9) + b

-4 = -9/2 + b

-4 + 9/2 = b

-4 + 4 $\frac{1}{2}$ = b

b = $\frac{1}{2}$
