Answer:

x² + y² - 8x -14y - 105 = 0

Step-by-step explanation:

The centre of the circle is (-7,0) and the radius is (4,7) . Firstly let's find the radius using Distance formula .

=> D = √{ (-7-4)²+(0-7)²}

=> D = √ 11² + 7²

=> D = √ 121 +49

=> D = √170

Now using the standard equation of circle ⭕ ,

=> ( x - h)²+(y-k)² = r²

=> ( x - 4)²+(y-7)²= (√170)²

=> x² + 16 -8x + y² + 49 -14y = 170

=> x² + y² -8x -14y = 170 -65

=> x² + y² - 8x -14y - 105 = 0

total surface area of cylinder=?

we have

total surface area of cylinder=2πr²+2πrh

total surface area of cylinder40π or 125.66cm².

Find the surface area of the cylinder.

Substituting the values given in the formula, We get,

⇒ Area of Cylinder = 2 × 3.14 × 2 ( 2 + 8 )

⇒ Area of cylinder = 2 × 3.14 × 2 ( 10 )

⇒ Area of cylinder = 2 × 3.14 × 20

Calculating further, We get,

⇒ Area of cylinder = 125.66 cm²

Answer:

12.5 is your answer buddy

Answer:

Step-by-step explanation:

So, lets think of this a simpler way.

What is 1/2 of 50?

Well, thats 25. That is 50%. We want 25%, which is 1/4 of 50.

So lets divide the 25 we got in half:

25/2

=

12.5

So this is your answer!

Answer:

4 l

the total ml of milk for 20 people is 4000ml and not 400 ml. 4000ml converted to litres is 4l

Step-by-step explanation:

total amount of milk for 20 people = 200 x 20 = 4000ml

1000 ml = 1 liter

4000ml /1000 = 4 l

Answer: 36

Step-by-step explanation: Keep multiplying 15 until you get 540. 36 * 15 is 540

Answer:

36 Crew members

Step-by-step explanation:

Divide 540 by 15, to find how much the new amount of passengers had increased. It should be 36.

Now to keep the ration even, you need to multiply the amount of Crew members by 36 too.

1/15=0.06666666667...

36/540=0.06666666667...

There's probably other ways to solve this, this is just how I did it.

Step-by-step explanation:

Sand needed can be determined by calculating the volume of a pyramid

Volume of a pyramid = 1/3 x ( length base x height)

1/3 x ( 4.5 x 4 x 2.5) = 15 ft^3

Answer:

true im not sure tho but trust me

Step-by-step explanation:

Answer:

a. 3/10

b. 25 people

Step-by-step explanation:

a. 12/40

simplify

3/10

b. 40 people so multiply everything by 5

5 x 5 =25 people

Answer:

a) 30%   & b) 25

Step-by-step explanation:

16+7+5+12 = 40

a) 12/40 = 0.3 = 3%

b) 5/40 = .125

    200 x .125 = 25

Answer:

[tex] \displaystyle 53.6ft[/tex]

Step-by-step explanation:

refer the attachment

let the height be h

since we are given the adjacent side and want to figure out opposite side we'll use tan function

so our equation is

[tex] \displaystyle \tan( {15}^{ \circ} ) = \frac{h}{200} [/tex]

cross multiplication:

[tex] \displaystyle h = 200\tan( {15}^{ \circ} ) [/tex]

by using calculator we acquire:

[tex] \displaystyle h \approx 53.6ft[/tex]

hence,

about 53.6ft high in the tree ate monkeys

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that  [tex]cos(x)=\frac{28}{39}[/tex]

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side

[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

Answer:

{aUb}' = {4, 12, 16}

Step-by-step explanation:

GIven S= { 2,2,4,6,8,8,8,10,10,12,14,16,16,16,16,18,18,20}

a= { 2,6,8,8,10,18}

b = { 2,8,10,14,18,20}

Required

(aUb)'

aUb = {2, 6, 8, 10, 14, 18, 20}

{aUb}' are values of the set S that are not in aUb. The required values are;

{aUb}' = {4, 12, 16}

Answer:

242

Step-by-step explanation:

Circles have a total of 360°

mDBG does not include mBA or mGA

This means that mDBG = 360 - ( mBA + mGA )

mBA = 28° ( this is given )

mGA = 90° ( this is also given; it's indicated by the right angle )

Thus, mDBG = 360 - ( 28 + 90 )

28 + 90 = 118

mDBG = 360 - 118

360 - 118 = 242

Hence, mDBG = 242

Answer:

Y = 15x + 30 and 8 hours

Step-by-step explanation:

She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.

She gets a solid $30 every week that is straight forward

To solve the function

150 = 15x + 30

subtract 30 from both sides

120 = 15x

divide 15 from both sides

8 = x

or

x = 8

You got this :)

Answer:

A. y = -3/2x + 9

Step-by-step explanation:

In slope intercept form (y = mx + b), b represents the y-intercept. Therefore, simply look on the graph where the line intersects with the y-axis. In this case, that is all that was needed since we can clearly see that equation A is the only one with a y-intercept of 9.

Answer:

a

Step-by-step explanation:

any two points on the line are

(0,9 ) and (4,3)

slope=(3-9)/(4-0)=-6/4=-3/2

y intercept is 9

so eq. of line is y=-3/2x+9
