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

Answers

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.

Jeremy is making a healthy ice cream using only ripe bananas and peanut butter, the recipe makes 4 servings and calls for a ratio of 5
bananas to 3 tablespoons of peanut butter if Jeremy has 30 bananas, how many tablespoons of peanut butter does he need
Tablespoons

Answers

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.

What is a ratio?

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.

The y-intercept for the line 2x + 3y = 18 is (0, y). What is the value of y

Answers

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

QUESTION 10 of 10: You have a need to purchase 30 units of a product and have them delivered to your company in five days. The sale price is $35 each. Sales tax on the product is 8%. Shipping price is $15. But there is also a 25% rush charge on the sales price added for deliveries less than seven days, which is also taxable. What will be the total cost of this purchase? O a) $1,050.00 b) $1,327.50 Oc) $1,396.50 O d) $1,432.50​

Answers

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

Answers

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:
