If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters. True False​

Answers

Answer:

True

Step-by-step explanation:

The Answer is 75.36 cm

2 x (pi)3.14 = 6.28

6.28 x (r)3 = 18.84

18.84 x (h)4 = 75.36

The statement, "If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters." is true.

What is cylinder?

"A cylinder is a three-dimensional geometrical structure which consists of two circular bases connected with a curved surface."

Formula to calculate the area of the lateral surface of a cylinder:

For a cylinder with radius r and height h,

the curved / lateral surface area is,

A = 2 × π × r × h

Given: r = 3 cm, h = 4 cm

Using the formula for area of lateral surface of a cylinder:

⇒ A = 2 × π × 3 × 4

⇒ A = 24 × π

⇒ A = 24 × 3.14

A = 75.36 sq.cm.

Therefore, given statement is true.

Step-by-step explanation:

All we have to do for this equation is cross multiply. This means we multiply 7 and 5 together and 5 and x+2 together. This will make the equation 35=5(x+2). Simplify this to get 35=5x+10. Subtract 10 from both sides to get 5x=25. You want to isolate x so you have to divide both sides by 5. This will make the equation x=5.

From a standard deck of cards, your first draw is a black card. You replace the card, and the second draw is a diamond. Which THREE statements are correct for the outcome of the event?

Answers

A, B, D

A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.

B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4

D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8

900% of what number is 7,470

Answers

Answer:

830

Step-by-step explanation:

7470/9 = 830

Answer:

900% of 7470=67230

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 7470 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 7470 is 100%, so we can write it down as 7470=100%.

4. We know, that x is 900% of the output value, so we can write it down as x=900%.

5. Now we have two simple equations:

1) 7470=100%

2) x=900%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

7470/x=100%/900%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 7470

7470/x=100/900

(7470/x)*x=(100/900)*x       - we multiply both sides of the equation by x

7470=0.11111111111111*x       - we divide both sides of the equation by (0.11111111111111) to get x

7470/0.11111111111111=x

67230=x

x=67230

now we have:

900% of 7470=67230

Eight eagle stamps and two raccoon stamps cost $2.80. Three eagle stamps and four raccoon stamps cost $2.35. Find the cost of each kind of stamp

Show work please

Answers

Answer:

Cost of each eagle stamp = $0.25

Cost of each racoon stamp = $0.4

Step-by-step explanation:

Given:

Cost of 8 eagle stamp and 2 racoon stamp = $2.80

Cost of 3 eagle stamp and 4 racoon stamp = $2.35

Find:

Cost of each stamp

Computation:

Assume;

Cost of each eagle stamp = e

Cost of each racoon stamp = r

So,

8e + 2r = 2.80........... Eq 1

3e + 4r = 2.35 ........... Eq 2

Eq 1 x 2

16e + 4r = 5.6 .........Eq3

Eq 3 - Eq 2

13e = 3.25

e = 0.25

Cost of each eagle stamp = $0.25

8e + 2r = 2.80

8(0.25) + 2r = 2.80

2 + 2r = 2.80

r = 0.4

Cost of each racoon stamp = $0.4

PLEASE HELP !!!

Answers

Answer:  4

============================================================

Explanation:

Refer to the table below (attached image). I've copied your table and added a third row at the bottom. This new row is the result of multiplying each payout value with the corresponding probability.

Example: for the first entry of this row, have 2*0.45 = 0.9

Once that third row is filled out, you add up everything in that row. That will lead to the expected value.

The expected value is: 0.9+1.2+0.6+0.8+0.5 = 4

Interpretation: You expect, on average, to win $4 each time you play the game. This assumes that the cost to play the game is 0 dollars. If the cost is something else, then it will affect the expected value.

Because the expected value is not 0, this game is not mathematically fair (the bias is leaning in favor of the player).

the perimeter of the rectangular window glass is 26 dm. if the area is 36 sq dm, what are the dimensions of the window glass?

Answers

The dimensions are 9x4. 9+4 adds up to 13, which is half of 26, or half of the perimeter, and 9x4 is equal to 36.

Answer:

w = 4 and l = 9 or

l = 4 and w = 9

Step-by-step explanation:

let l = length

let w = width

2l + 2w = 26

lw = 36

l = 36/w

2(36/w) + 2w = 26

72/w + 2w = 26

(72 + 2w²) ÷ w = 26

cross-multiply:

2w² + 72 = 26w

2w² - 26w + 72 = 0

factor:

2(w² - 13w + 36) = 0

2(w - 4)(w - 9) = 0

w = 4 and l = 9 or vice versa

Which equation in rectangular form describes the parametric equations x=2-3 cos t and y=1+4 sin t?​

Answers

Answer:

The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].

Step-by-step explanation:

We proceed to use the following trigonometric identity to derive an expression in rectangular form:

[tex]\cos^{2} t + \sin^{2} t = 1[/tex] (1)

Where:

[tex]\cos t = \frac{2-x}{3}[/tex] and [tex]\sin t = \frac{y-1}{4}[/tex]

Then, we expand the expression as follows:

[tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex] (2)

The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].
