Answer 1

Answer:

22π cm³

Step-by-step explanation:

Let's start with the formulas for volume:

volume of cylinder = πr²h

volume of cone = (1/3)πr²h

Notice the formulas above for the volume of a cylinder and the volume of a cone. The only difference is that the volume of the cone has the fraction 1/3 multiplying the rest, and the rest is exactly the same as in the volume of the cylinder.

That means that if a cylinder and a cone have the same radius and height, the volume of the cone is 1/3 the volume of the cylinder.

Here, the cylinder and cone do have the same radius and height. That means the volume of the cone is 1/3 the volume of the cylinder.

The volume of the cylinder is 66π cm³.

The volume of the cone is 1/3 of that volume, so divide 66π cm³ by 3 to find it.

volume of cone = 66π cm³ / 3 = 22π cm³

Answer: 22π cm³

Step-by-step explanation:

Li has t toy bricks.
She only has red bricks and blue bricks.
Li picks two bricks, one after the other.
If the first brick she picks is red, the probability that the second brick is red is
is 23
is 1 0
7
If the first brick she picks is blue, the probability that the second brick is red is
10
Calculate the value of t.

Answers

Probabilities are used to determine the chances of events

The value of t is 16

How to determine the probability

The number of bricks is given as t

Let the number of red bricks be x.

So, the number of blue bricks would be t - x

So, the probability values are:

[tex]\frac{x -1}{t - 1} = \frac 13[/tex] --- when the both bricks are red

[tex]\frac{x}{t - 1} = \frac 25[/tex] --- when only the second brick is red

Divide both equations

[tex]\frac{x -1}{t - 1} \div \frac{x}{t - 1} = \frac 13 \div \frac 25[/tex]

Divide

[tex]\frac{x -1}{x} = \frac 13 \div \frac 25[/tex]

This gives

[tex]\frac{x -1}{x} = \frac 13 *\frac 52[/tex]

Evaluate the product

[tex]\frac{x -1}{x} = \frac 56[/tex]

Cross multiply

[tex]6x - 6 = 5x[/tex]

Collect like terms

[tex]6x - 5x = 6[/tex]

[tex]x = 6[/tex]

Recall that:

[tex]\frac{x -1}{t - 1} = \frac 13[/tex]

So, we have:

[tex]\frac{6 -1}{t - 1} = \frac 13[/tex]

[tex]\frac{5}{t - 1} = \frac 13[/tex]

Cross multiply

[tex]t -1 =15[/tex]

Add 1 to both sides

[tex]t = 16[/tex]

Hence, the value of t is 16

Answers

Answer:

m=0.7404, b=3.9117m=0.7404,b=3.9117

y=0.7404x+3.9117y=0.7404x+3.9117

x=18x=18

y=0.7404(18)+3.9117=17.2389y=0.7404(18)+3.9117=17.2389

Residual

16-17.2389= -1.238916−17.2389=−1.2389

The residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Now, We know that;

Equation is,

y = bx + a

Where,

b = (xy) - (x) (y) / x² - y²

Here, We have;

x = 12.5

y = 13.17

(xy) = 211.17

Hence, We get;

b = (211.17 - 164.625) / (219.17 - 156.25)

b = 0.74

So, We get;

y = bx + a

13.17 = 0.74 × 12.5 + a

a = 3.92

So,

y = 0.74x + 3.92

y = 0.74 × 18 + 3.92

y = 17.24

Thus, the residual value for x = 18 is,

⇒ 16 - 17.24

⇒ - 1.24

Rhea sold 6 boxes of blueberry muffins and 8 boxes of corn muffins at the bake sale. Each box contained 18 muffins. The muffins cost $0.50 each. What is the total amount raised by the sale of the muffins?

Please help me (and thanks if you are, I very much appreciate it :))

Answers

Answer:

$126.00

Step-by-step explanation:

1 you Multiply .50×18=9

so the ratio is 9 per box

you add 6+8=14 and then 14×9=126

The answer is $126.00.

First, you want to add together how many boxes of muffins she sold (8+6= 14)

Then, you need to multiply the amount of boxes by how many muffins are in each box (18*14 = 252)

Lastly, you multiply the amount of muffins sold by how much each muffin cost (252*0.50 = 126)

And that’s how you get $126.00.

ABCD is an 8 by 6 rectangle. AC is a diagonal with length 10. Point E is on AC such that BE is perpendicular to AC . What is the length of BE

Answers

Answer:

The length of BE is 5 units.

Step-by-step explanation:

ABCD is rectangle

AC is a diagonal and BD is a diagonal too.

Diagonals of rectangle are equal and bisect each other perpendicularly.

So, AE = BE

AE = 1/2 × AC

= 1/2 × 10

= 5

BE = 5

Hence the length of BE is 5 units.

Answers

The lengths JL and PM are the lengths that make up the triangle JMP

The length of JL is 78 unitsThe length of PM is 47.5 unitsThe measure of angle MLK is 105 degrees

How to calculate side length JL?

The side length JL is twice the side length PN.

So, we have:

JL = 2 * PN

This gives

JL = 2 * 39

JL = 78

Hence, the length of JL is 78 units

How to calculate side length PM?

The side length PM is half the side length KL.

So, we have:

PM = 0.5 * KL

This gives

PM = 0.5 * 95

PM = 47.5

Hence, the length of PM is 47.5 units

How to calculate angle MLK?

The angle MLK is congruent to the angle JMP.

So, we have:

MLK = JMP

This gives

MLK = 105 degrees

Hence, the measure of angle MLK is 105 degrees

Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

The diagram is shown.

We know that when two lines intersect each other then the vertically opposite angles are equal.

Then

x = 52° because they are vertically opposite angles.
