Answer:

Cone A, Cone C, Cone B

Step-by-step explanation:

The volume of a cone is V=πr^2h/3 where V represents the volume, r represents the radius, and h represents the height.

That means the volume of cone A would be:

V = π * 5^2 * 6/3

V = π * 25 * 2

V = 50π

And the volume of Cone B would be:

V = π * 7^2 * 4/3

V = π * 49 * 4/3

V = 65.33π (about)

Lastly, the volume of Cone C would be:

V = π * 6^2 * 5/3

V = π * 36 * 5/3

V = 60π

65.33π > 60π > 50π

Therefore, Cone B has the largest volume, then Cone C, and, lastly, Cone A.

Answer:

t = 1

Step-by-step explanation:

16 - 2t = 5t + 9

1) First move 5t to the left side

16 - 2t - 5t = 9

2) Then move 16 over to the right side

-2t -5t = 9 - 16

3) simplify both sides

-7t = -7

4) divide both sides by 7

-t = -1

5) divide both sides by -1

t = 1

Answer: The answer is 4

Step-by-step explanation:

P, Q, and R are collinear points.

Q lies between P and R

Therefore ,

PR = PQ + QR

5x = 10 + 3x-2

5x - 3x = 8

2x = 8

x = 8/2

x =4

Answer:

it is the second option. answer is x[tex]\leq[/tex]-8/3 or x>4

Step-by-step explanation:

we have the inequality 3x+8/x-4=0

we first multiply both sides by 4 the 4 cancels out on the left-hand side and  4*0 is 0 so we now have 3x+8=0 then we subtract both sides by 8 and get 3x=-8 then we divide both sides by 3 and get x=-8/3  

x[tex]\leq[/tex]-8/3 works in the original inequality

-8/3[tex]\leq[/tex]x[tex]\leq[/tex]4 does not work

x>4 does work

To find the following product

[tex] \sqrt[3]{4} \times \sqrt{3} [/tex]

we can rewrite the radicals and then replace them into the multiplication, as follows:

[tex] \sqrt[3]{4} = 4^{\frac{1}{3}} = 4^{\frac{1}{3} \times \frac{2}{2}} = 4^{\frac{2}{6} = \sqrt[6]{16}[/tex]

[tex] \sqrt{3} = 3^{\frac{1}{2}} = 3^{\frac{1}{2} \times \frac{3}{3}}} = 3^{\frac{3}{6}} = \sqrt[6]{27} [/tex]

[tex] \sqrt[3]{4} \times \sqrt{3} = \sqrt[6]{16} \times \sqrt[6]{27} = \sqrt[6]{16 \times 27} = \sqrt[6]{432} [/tex]

Answer:

1. 50

2. 12

Step-by-step explanation:

Answer:

2. 50 stamps

3. 12 minutes

Step-by-step explanation:

2. Darius had 15 stamps, then he ordered 3 rolls. You can determine how many he got from the rolls by subtracting the total from 15. 165 - 15 = 150.

Now we know that there were 150 stamps in the rolls Darius ordered. Divide 150 by 3 (3 rolls) to find the number of stamps in each roll!

150/3 = 50.

3. First, remember that 1 hour = 60 minutes.

We want to find how long America played soccer on Monday, which is the same amount of time she played on Tuesday and Wednesday as well. This means we can subtract Thursday and Friday's time from 60 minutes, then divide that time by 3, to find the time she played on Monday.

60 - 14 - 10

= 36 minutes

Now, we divide 36 minutes by 3 to get 12 minutes.

Good luck on your assignment

The coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).

Let C be the mid-point of the line segment AB.

A = (x₁, y₁)

B = (x₂, y₂)

C = (x, y)

Then the midpoint will be

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

AB has endpoints at A(2, 6) and B(6, 8). Then we have

(x₁, y₁) = (2, 6)

(x₂, y₂) = (6, 8)

Then the mid-point will be

x = (2 + 6) / 2

x = 8 / 2

x = 4

y = (6 + 8) / 2

y = 14/2

y = 7

Then the coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).

Answer:

[tex]\frac{21.05}{0.2}=105.25[/tex]

Step-by-step explanation:

you have to do long division, but there is a number of steps, too many to put in here, but just check on calculator if you want to make sure

21.05 divided by 0.2 equals to 105.25

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.

The process of dividing a number up into equal parts, and finding how many equal parts can be made.

Division is a process of splitting a specific amount into equal parts. For example, we can divide a group of 20 members into 4 groups of 5 members.

Given that, 21.05 divided by 0.2

So, 21.05 ÷ 0.2 = 21.05/0.2

Multiply by 100

= 21.05 x 100 / 0.2 x 100

= 2105/20

= 421/4

= 105.25

Hence, 21.05 divided by 0.2 equals to 105.25
