Answer:

The answer is 24501.42

Step-by-step explanation:

Diameter=34m

Radius=34÷2 = 17m

Height=27m

Volume=πr^2h

Volume= 3.14×(17)^2×27

Volume= 3.14×289×27

Volume= 24501.42m^2

Answer:

x = 40

Step-by-step explanation:

x + 100 +  x = 180 {Straight line angles}

2x   + 100 = 180      {subtract 100 from both sides}

         2x = 180 - 100

         2x = 80      {Divide both sides by 2)

           x = 80/2

          x = 40

Answer:

x=40

Step-by-step explanation:

2x+100=180

2x=180-100

2x=80

x=40

Answer:

the pythagoream theorem, a^2+b^2=c^2

1. 13in.

2. 31.6 yd.

3. 16.1 m.

Step-by-step explanation:

c is the hypotonus (the diagonal line on a right triangle)

if you are trying to find c, you square the two sides that are given and then add them up.

For example number 1:

So 5x5=25   and    12x12=144

add those two values together, 25+144=169

the last step is to find the square root of that last sum (169)

√169 = 13.

Step-by-step explanation:

Answer:

B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.

Step-by-step explanation:

The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide

[tex] \frac{fe}{ab} [/tex]

[tex] \frac{1}{3} [/tex]

The scale factor is 1/3.

The new points are at A'(-2,0) B'(-2,1) C'(-1,0).

Then we apply reflection.

Since FED is in the 4th quadrant, we are going to reflect across the y axis.

That becomes using formula

(x,y) goes to (-x,y) when reflecting across yaxis.

A''(2,0) B''(2,1) C''(1,0)

Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.

Answer:

b

Step-by-step explanation:

Answer:

s = 17 units

Step-by-step explanation:

In triangle ABD,

(AB)² + (BD)² = (AD)² (by Pythagoras Theorem)

=> 8² + 15² = s²

=> 64 + 225 = s²

=> s = [tex]\sqrt{289}[/tex]

=> s = 17 units

The values of x and y in the following equation system are 20 and 110, respectively.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.

given a system of equation:

30x + 4y = 1,040.....(1)

12x + 16y = 2,000...…(2)

We will solve it by using substitution method,

Multiply with 2.5 in equation (2) and subtract it from equation (1)

30x + 4y - 30x - 40y = 1040 - 5000

36y = 3960

y = 110

Substitute this value of y in equation (1)

30x + 440 = 1040

30x = 600

x = 20

Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.

The equation representing the total number of students in the class: b+g=36

The equation representing the total number of boys in the class: b=2g-3

Sentence representing solution: The number of boys in the class is 13 and the number of girls in the class is 26

Step-by-step explanation:

x=33 y= -22

52 -33

-22=33m+b

-33=52+b

-11=19m

m=-11/19

-22= 19.105+ b

b= -41.105

y=-11x/19 -41.105

x intercept when y=0

0=-11x/19 -41.105

41.105=-11x/19

-11x= 780.995=781

x= - 71

Distance travel by Monica = 628 ft

Step-by-step explanation:

Given:

Radius of whee l = 1 ft

Number of revolution = 100

Find:

Distance travel by Monica

Computation:

Distance travel by Monica = 100[Circumference of wheel]

Distance travel by Monica = 100[2πr]

Distance travel by Monica = 100[2(3.14)(1)]

Distance travel by Monica = 100[6.28]

Distance travel by Monica = 628 ft
