A cylindrical pillers has a diameter of 56 cm and is of 35 m high there are 16 pillers around the building find the cost of painting the curved surface area of all the pillars at the rate of 5.50 per 1m square ​

Answers

Answer:

Answer:

Total cuŕved surface area of the pillars = 985.6m²Total cost of painting = Rs.5420.8

Explanation:

Given,

A cylindrical pillar with dimènsions,

r(radius) = 56/2 = 28cm. [ Since d = r/2]h(height) = 35m

There are 16 such pillars. Find the cost of paiñting the the curved surface area of all pillars 5.50/m²

Conversion of the dimensioñs in same units.

Radius = 28cm

= 28 ÷ 100 [Since 1m = 100]

= 0.28m

Cuŕved surface area of the pillar is given by,

→ 2πrh

Where,

Taking ‘π’ as 22/7

→ 2*(22/7)*(0.28)*(35)

3a + 6 = 24                                  Subtract 6 from both sides.

3a = 24 - 6                                   Combine

3a = 18                                         Divide both sides by 3

3a/3 = 18/3

a = 6

Answer:

1.

3a + 6 OR 3(a + 2)

2.

a = 6

Step-by-step explanation:

1.

(a + 2) + (a + 2) + (a + 2) = a + a + a + 2 + 2 + 2

= 3a + 6 or 3(a + 2)

2.

A community theater sells about 150 tickets to a play each week when it charges $20 per ticket.
For each $2 decrease on price about 25 more tickets per week are sold. Write a quadratic function to
find how the theater can maximize weekly revenue. What should the theater charge to maximize
revenue? What is the maximum weekly revenue? (6 pts) (Show all work.)

What is the equation:
What should the theater charge?
What is the maximum revenue?



Answers

Answer:

r = 12.5p(32 -p)$16 per ticket$3200 maximum revenue

Step-by-step explanation:

The number of tickets sold (q) at some price p is apparently ...

  q = 150 + 25(20 -p)/2 = 150 +250 -12.5p

  q = 12.5(32 -p)

The revenue is the product of the price and the number of tickets sold:

  r = pq

  r = 12.5p(32 -p) . . . . revenue equation

__

The maximum of revenue will be on the line of symmetry of this quadratic function, which is halfway between the zeros at p=0 and p=32. Revenue will be maximized when ...

  p = (0 +32)/2 = 16

The theater should charge $16 per ticket.

__

Maximum revenue will be found by using the above revenue function with p=16.

  r = 12.5(16)(32 -16) = $3200 . . . . maximum revenue

_____

Additional comment

The number of tickets sold at $16 will be ...

  q = 12.5(32 -16) = 200

It might also be noted that if there are variable costs involved, maximum revenue may not correspond to maximum profit.

Answers

Answer:

a) UT² = ST · (RS + ST)

b) UT = 6 in

Step-by-step explanation:

Secant : a line that intersects the circle at two pointsTangent : a line that touches the circle at one point

If a secant and a tangent of a circle are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.

UT² = ST · (RS + ST)

Given:

RT = 9 inST = 4 inRS + ST = RT
⇒ RS + 4 = 9
⇒ RS = 5

Using:  UT² = ST · (RS + ST)

⇒ UT² = 4(5 + 4)

⇒ UT² = 36

⇒ UT = √36 = 6 in

solve for w. 5 + 2w = 17

Answers

Answer:

w=6

Step-by-step explanation:

5 + 2w = 17

Subtract 5 from each side

5-5 + 2w = 17-5

2w = 12

Divide each side by 2

2w/2  = 12/2

w = 6

Solution:

Note that:

Given equation: 5 + 2w = 17

To solve this problem, isolate the variable by subtracting 5 to both sides of the equation.

=> 5 + 2w = 17=> 5 - 5 + 2w = 17 - 5=> 2w = 12

Then, divide 2 both sides to further isolate the variable.

=> 2w = 12=> 2w/2 = 12/2=> w = 6

The solution to the equation is 6.

City Park is a right triangle with a base of 40 yd
and a height of 25 yd. On a map, the park has a
base of 40 in. and a height of 25 in. What is the
ratio of the area of the triangle on the map to
the area of City Park?

Answers

Answer:

Let's Convert yards into inches

Base = 40 yards = 1440 inches

Height = 25 yards = 900 inches

Base (Map)/Base (Actual)

40/1440 = 1 : 36

Height (Map)/Height (Actual)

25/900 = 1 : 36

I hope it helps you!

Step-by-step explanation:

Let's expand our knowledge even more by explaining.

The scale of the height and the width is 1 inch equals 1 yard.

the scale of the area would be 1 square inch equals 1 square yard.

for example:

the area of a triangle is equal to 1/2 * base * height.

the base on the map is 40 inches and the height on the map is 25 inches.

the area on the map is therefore 1/2 * 40 * 25 = 500 square inches.

the base in the real world is 40 yards and the height in the real world is 25 yards.

the area in the real world is therefore equal to 1/2 * 40 * 25 = 500 square yards.

the ratio of the area on the map to the area in the real world is 500 square inches / 500 square yards equals 1 square inch / 1 square yard.

that's 1 square inch to 1 square yard.

in general, if the scale in the linear measurements were a/b, then the scale in area would be (a/b)^2.

since your scale in linear measurements is 1/1, then the scale in area would be (1/1)^2 which is equal to 1/1.

assuming the scale in linear measurements were 1/2, then the scale in area would be (1/2)^2 = 1^2/2^2 = 1/4.

Find the area of the circle. Give your answer in terms of x. C= pie over 7

Answers

Answer:

Assuming C stands for Circumference we will assume the circum is pi/7

Therefore x = 1/196pi

Step-by-step explanation:

First find the radius with C = 2  * r * pi

1/7pi = 2 * r * pi

r = (1/7pi)/2pi

r = 1/14

Now for the area we have A = r^2 * pi

A = (1/14)^2 * pi

A = 1/196 * pi

$4.00 and $0.40
$2.00 and $0.40
$2.00 and $4.00

Answers

Answer:

$4.00 and $0.40

Step-by-step explanation:

Preferred dividend = $100 x 4% = $4 per share

$4 x 10,000 shares = $40,000

$80,000 paid - $40,000 preferred = $40,000 common dividend

$40,000 / 100,000 common shares = $0.40 per share

The dividends per share for preferred and common stock for the year is: $4.00 and $0.40.

Dividends per share for preferred and common stock

Dividends per share for preferred = $100 x0.04

Dividends per share for preferred = $4 per share

Common dividend=$80,000 -($4 x 10,000 shares)

Common dividend=$80,000 - $40,000

Common dividend=$40,000

Dividends per share for common stock=$40,000 / 100,000

Dividends per share for common stock = $0.40 per share

Inconclusion the dividends per share for preferred and common stock for the year is: $4.00 and $0.40.
