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
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)

Answer:
Step-by-step explanation:
a + 2 + a+2 + a + 2 = 24 Combine the left
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.
24 = 3a + 6
24 - 6 = 3a
18 = 3a
18/3 = 6
a = 6

Devon is making table runners for his niece's wedding. The short tables are 6 feet
(ft) long, and the long tables are 10 ft long. Each runner will overhang its table by 8
inches (in.) on each end. Devon was told there will be 12 small tables and twice that
number of long tables. How many total yards (yd) of fabric will he need to make the
table runners, assuming no waste? (Note: 12 in. = 1 ft and 3 ft = 1 yd.)
The sum of the lengths of the tables and the total length of overhang
give the length of fabric that Devon needs.
Response:
The total yards of fabric needed to make the table runners is 12 yd.How can the given dimensions be added to obtain the length of fabric needed?The given parameters are;
Length of the small tables = 6 feet
Length of the long tables = 10 feet
Length of overhang on each end = 8 inches
Number of small tables = 12
Number of long tables = 2 × 12 = 24
Required:
The yards of fabric needed to make the table runners.
Solution;
The total number of tables = 12 + 24 = 36
Length of overhang for each table = 8 inches + 8 inches = 16 inches
Sum of the length of the overhang = 36 × 16 inches = 576 inches
From the given unit conversion factors, we have;
Sum of the length of overhang = 576 inches ÷ 12 inch/feet = 48 feet
Length of the tables = 12 × 6 feet + 24 × 10 feet = 312 feet
Total length of table runner = 312 feet + 48 feet = 360 feet
Length of table runner needed = 360 feet ÷ 3 feet/yd = 120 yd.

solve for w. 5 + 2w = 17
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 = 17To solve this problem, isolate the variable by subtracting 5 to both sides of the equation.
=> 5 + 2w = 17=> 5 - 5 + 2w = 17 - 5=> 2w = 12Then, divide 2 both sides to further isolate the variable.
=> 2w = 12=> 2w/2 = 12/2=> w = 6The solution to the equation is 6.
helpp pleass love you if you answer meeee
Answer:
C. No solution.
Step-by-step explanation:
Due to the y-intercepts (When the equation is in slope-intercept form: 1.5, and 3.5) we can identify that the equations are parallel from each other.
The slopes are the same, but the y-intercepts are different, the equations will be 2 (y) apart since each will intersect at different values. This means that both equations can't intersect with each other, making it impossible to find a solution.

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?
Answer:
r = 12.5p(32 -p)$16 per ticket$3200 maximum revenueStep-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.

-100 on both sides
50w ≥ 17,900
Divide both sides by 50
w ≥ 358

what is the remainder when you divide 2x^3+4x^2 - x +3 by x+2
Answer: The required remainder is 5.
Step-by-step explanation: We are given to find the remainder when we divide the following cubic polynomial by (x+2 :
3 f(x)=2x^ 3 +4x^ 2 - 6^ 2 -x+
(i)
We have the following theorem:
Remainder theorem: If a polynomial p(x) is divided by the factor (x-a), then the remainder is p(a).
So, for the given linear factor, we have
x + 2 = 0
Rightarrow x=-2
Substituting x = - 2 in equation (i), we get
f(- 2)
=2(-2)^ 3 +4(-2)^ 2 -(-2)+3
=-16+16+2+3
=5 .
Thus, the required remainder is 5.

(i) Find the factors of the given polynomial.
(ii) if she purchase 5kg papaya, what money she have to pay?
Answer:
p ( x ) = ( x- 6 ) ² - 256
Step-by-step explanation:
1- Add the same value to both sides
2- Add 36 to the expression
3- Add 36 to the left-hand side
4- Factor the expression
5- Move the constant to the right
6- Calculate
The factors of the given polynomial is (x-10) (x+22) and the price of 5 kg papaya is 5x²-60x-1100.
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Given:
p(x) = x² – 12x – 220
i) These two terms are 22x and -11x.
p(x) = x²-12x-220
p(x) = x²+22x-10x-220
Taking x common from the first two terms and -10 from the last two terms,
x(x+22)-10(x+22)
(x-10) (x+22)
ii) We are given that the rate of papaya per kg is p(x) = x²-12x-220.
1 kg = x²-12x-220
5 kg = 5(x²-12x-220)
5 kg = 5x²-60x-1100

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?
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.
