Given:

A triangle with vertices A(0,0), B(6,0), and C(0,9) is rotated 360 about the y-axis.

To find:

The volume of the figure.

Solution:

Points A(0,0) and C(0,9) lies on the y-axis. Length of AC is 9 units.

Points A(0,0) and B(6,0) lies on the x-axis. Length of AB is 6 units.

If a triangle with vertices A(0,0), B(6,0), and C(0,9) is rotated 360 about the y-axis, then it will form a cone with radius 6 units and height 9 units.

Volume of a cone is

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

where, r is radius of the base and h is vertical height of the cone.

Putting r=6 and h=9, we get

[tex]V=\dfrac{1}{3}\pi (6)^2(9)[/tex]

[tex]V=\pi (36)(3)[/tex]

[tex]V=108\pi[/tex]

Therefore, the volume of the figure is [tex]108\pi[/tex] sq. units.

Answer:

20 Mystery DVD’s

Step-by-step explanation:

32/8=4

4*5=20

Answer:

There are 20 Mystery DVD's.

Step-by-step explanation:

Since the ratio of Drama to Mystery is 8:5, then we can conclude that 32:x is another equivalent form of the ratio, given that 32 represents drama, and x represents the unknown number of mystery.  

Set up the ratios as 8/5 as one fraction, and 32/x as another, but make them equal each other.  Cross multiply the numerators and denominators, then you will get 8x=160

divide both sides to solve for x.

x=20

Answer:

18

Step-by-step explanation:

basic math :/

Answer:

6

Step-by-step explanation:

2x + 3y = 18 can be simplified into an y = mx + b equation, where b is the y intercept.

First, subtract 2x from both sides to get 3y alone.

3y = 18 - 2x

Then, divide both side by 3 to get y completely alone.

y = 6 - 2x

Rearrange the equation to be in the form of y = mx + b;

y = -2/3x + 6

6 is our Y intercept.

You can also use a graphing calculator if you want to check your answer, desmos is a great graphing calculator you can use.

Answer:

6

Step-by-step explanation:

Y=mx+c

C is y intercept

2x+3y=18

3y=18-2x

Y=(-2x+18)/3

Y=-2/3x+6

Answer:

  ∆KAF, by rule LA

Step-by-step explanation:

The angle bisector divides angle FAP into two equal angles KAF and KAP. The two right triangles share side KA, so we have a leg KA and an angle KAF, KAP that are the same in the two triangles. That is enough to invoke rule LA (leg, angle) to claim congruence.

  ∆KAP ≅ ∆KAF by rule LA

Answer: d) $1,432.50​

Step-by-step explanation:

Sales price = $35

25% rush charge = 35 * 25% = $8.75

Rush charge is taxable = (35 + 8.75) * 8% = $3.5

Total purchase price per unit = 35 + 8.75 + 3.5 = $47.25

Total cost = Total Purchase + Shipping

= (47.25 * 30) + 15

= $1,432.50

Answer:

​x + 49 + 28 = 180​

Step-by-step explanation:

​The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.

Therefore, since angles on a straight line is 180°, thus:

​x + 49 + 28 = 180​

Answer:

​x + 49 + 28 = 180​

THIS ANSWER IS CORRECT

The unit price of 12 gallons of gasoline that costs $39.48 is $3.29 per gallon

The given parameters are:

Gallons = 12

Cost = $39.48

The unit price is calculated as:

Unit = Cost/Gallon

So, we have:

Unit = $39.48/12

Divide

Unit = $3.29

Hence, the unit price of 12 gallons of gasoline that costs $39.48 is $3.29 per gallon

Answer:

can u show me a pic of the question so it is easier

The healthy ice cream Jeremy is making has 30 bananas and requires 18 tablespoons of peanut butter.

The ratio describes the amount of quantity in simplest form, a:b can be written as 'a/b' for convenience.

Given the healthy ice cream, Jeremy is making requires 5 bananas and 3 tablespoons of peanut butter.

From the given question itself, we can conclude that bananas and peanut butter are in direct proportion as the increase in one quantity will result in an increase of another quantity and we can write this in proportion and let the no. of tablespoons of peanut butter requires for 30 banans is x.

∴ 5 : 3 : : 30 : x.

Or

5/3 = 30/x.

5x = 90.

x = 18.

So, Jeremy needs 18 tablespoons of peanut butter for the 30 bananas he has.
