Answer: [tex]249.48\ m^2; 369.168\ m^3[/tex]

Step-by-step explanation:

Given

Cost of white-washing =Rs. 4989.60

Rate =20 per meter square

So, inside area of = [tex]\dfrac{4989.60}{20}=249.48\ m^2[/tex]

The surface area of dome= [tex]4\pi\ r^2=249.48[/tex]

[tex]4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m[/tex]

The volume of air in the dome [tex]V=\frac{4}{3}\pi r^3[/tex]

[tex]V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3[/tex]

Answer:

It took Mr. Holloway 28 weeks to make 7 guitars.

Step-by-step explanation:

The question is incomplete, but if we are trying to find out how many weeks it would take him to make 7 guitars then the answer would be 28.

First you have to find out how many weeks it takes him to make 1 guitar.

8 ÷ 2 = 4 (4 weeks to make 1 guitar)

Then you have to multiply 4 by 7 since it takes 4 weeks to make 1 guitar.

4 * 7 = 28 (28 weeks to make 7 guitars)

Answer:

28 weeks

Answer:

XY=13

Step-by-step explanation:

From the triangles, you can see XY=PR

XY=(2x+3)

PR=(4x-7)

plug in the values into the equation

2x+3=4x-7

solve

-2x=-10

x=5

Don't forget to substitute x into 2x+3

2(5)+3=XY

13=XY

Answer:

E) 613.9 m2

Step-by-step explanation:

sum of measures of interior angles of a polygon of n sides:

(n - 2)180

For a pentagon:

(5 - 2)180 = 3(180) = 540

measure of one interior angle of a regular pentagon:

540/5 = 108

Draw a segment from the center of the pentagon to the top vertex. Now you have a right triangle.

The triangle has a 90 deg angle where the segment in the figure meets the side of the pentagon. Let half of the side of the pentagon be x. x is a side of the right triangle.

For the 54 deg angle in the triangle, 13 m is the opposite leg, and x is the adjacent leg.

tan A = opp/adj

tan 54 = 13/x

x = 13 m/tan 54 = 9.445 m

x is half of the side of the pentagon.

2x is the side of the pentagon.

2x = 2(9.445 m) = 18.89 m

The given 13 m segment is the apothem of the pentagon.

A = nsa/2

where n = number of sides, s = length of 1 side, a = length of apothem

A = (5)(18.89 m)(13 m)/2

A = 613.9 m^2

Answer: E) 613.9 m2

Answer:okkk

Step-by-step explanation:

If you want to simplify the expression, combine like terms

x and 3x go together, so they make 4x.

and 4 is just 4

So, the answer is

4x + 4

Answer:

4x+4

Question 1: 28.50 - 3x = 12

Question 2: $5.50

Answer:

Step-by-step explanation:

Question 1: 28.50 - 3x = 12

Question 2: $5.50

Answer:

(4/25)^1/2 = 2/5

(4/25)^-1/2 = 5/2

Step-by-step explanation:

(4/25)^1/2 and (4/25)^-1/2

recall that a^1/x = x√a and a ^-1/x = 1/ x√a

Hence (4/25)^1/2

Applying the laws of indices stated above

(4/25)^1/2 = √(4/25)

Recall that √a/b = √a/√b

Hence √4/25 = √4/√25

= 2/5

(4/25)^-1/2

Applying the laws of indices stated above

(4/25)^-1/2 = 1/√(4/25)

= √(25/4)

= √25/√4

= 5/2

Answer:

5

Step-by-step explanation:

since the sides are the same size, then the equation should be combined into x+2=2x-3

then subtract an x from both sides: 2=x-3

then add 3 to both sides: 5=x

and you have your answer

hope this works

Answer:

x=5

Step-by-step explanation:

x+2=2x-3

-x on both sides=

2= x-3

then -2 on both sides

0= x-5

this means that x must be 5 so that positive 5- negative 5 equals 0 :)

Answer:

26

Step-by-step explanation:

Let 10 be a, and 24 be b, and the undefined hypotenuse be c.

[tex]a^2 + b^2 = c^2[/tex]

[tex]10^2 + 24^2 = c^2[/tex]

100 + 576 =  c

c = 676

[tex]\sqrt{100} + \sqrt{576} = \sqrt{676}[/tex]

[tex]10^2 + 24^2 = 26^2[/tex]

c = 26

The value of the undefined line is 26.

Tank A capacity = 550 gallons       66% x 550 gallons = 363 gallons in Tank A

How about the water in tank B?

ratio of  11: 15      11/15 = 550/x          550 * 15/11 = cap B = 750 gal       53% 0f 750 = .53 x 750 = 397.5 gal in tank B

Answer: 840 people

Step-by-step explanation:

They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.

The percentage of people who prefer sausage pizza is therefore:

= 21/40 * 100%

= 52.5 %

If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:

= 52.5% * 1,600

= 840 people

Answer:

answer=7

Step-by-step explanation:

Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7
