Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

233445.54 gallons  (from conversion tables)

Answer: 5x

Step-by-step explanation:

5x + 3x = 8x

Answer:

5x + 10y + 5z

Step-by-step explanation:

Given the expression

[tex]\frac{1}{2}(10x+20y+10z)\\[/tex]

Expand the parenthesis using the distributive law;

[tex]\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z[/tex]

Hence the required solution is 5x + 10y + 5z

Answer:

Step-by-step explanation:

The equation of the circle is ( x + 6 )² + ( y - 4 )² = 36 and the radius is r = 6 units and the center of circle is P ( -6 , 4 )

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the equation of circle be represented as A

Now , the value of A is

Let the radius of the circle be r = 6 units

The point of center of the circle is at P ( x , y )

The coordinates of the point P is = P ( -6 , 4 )

And , standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

On simplifying , we get

( x - ( -6 ) )² + ( y - 4 ) = 6²

( x + 6 )² + ( y - 4 )² = 36

Therefore , the value of A is ( x + 6 )² + ( y - 4 )² = 36

Hence , the equation of circle is ( x + 6 )² + ( y - 4 )² = 36

Answer:

C

Step-by-step explanation:

We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71  we can check our work by doing

42 + 67+ 71 = 180. We also know 67 + 42 = 109.

Lets look at our answers;

A. 109 = 180 + x  When solved it gave me; x = -71. We got a positive 71 so this is incorrect.

B. x + 42 = 67   When solved it gave me;  x = 25, which is incorrect.

C. x = 180 - 109 When solved it gave me; x = 71

D. 42 + 67 - x = 180 When solved it gave me; x =  - 71

Therefore the answer is C.

8a. 0 8b. -1/3

Step-by-step explanation:

slope formula: [tex]\frac{y_{2} - y_{1}}{x_{2} - x{1}}[/tex]

8a. => (8 + 12)/(17 - 17) = 20/0 = 0

8b. (1 + 2)/(-3 - 6) = 3/-9 = - 1/3

Answer:

8a: 0 8b: -1/3

Step-by-step explanation:

slope is y2-y1/x2-x1

8a: 8+12/0=0

8b: 1+2/-3-6=3/-9=-1/3

[tex] \sf{}b_{1} = - 72 \: \: \: or \: \: \: b_{2} = 72[/tex]

.

[tex] \sf{65}^{2} + {b}^{2} = {97}^{2} [/tex]

[tex] \sf{}4.225 + {b}^{2} = 9.409[/tex]

[tex] \sf {b}^{2} = 9.409 - 4.225[/tex]
