Answer:
1.797 mm
Step-by-step explanation:
The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.
The volume of a cylinder equation is:
V = hπr^2
- We want to find h
- We are given diameter and we will want the radius so we divide
21.17/2 = 10.585
r = 10.585
So to find h we manipulate the equation by dividing both sides by pi and r^2
resulting in the following:
h = [tex]\frac{V}{\pi r^2}[/tex]
now substitute given values and we get
h = [tex]\frac{28470}{\pi10.585^{2} }[/tex] = 80.883
Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).
Thickness = 80.883/45 = 1.797 mm

What is the sum of the 15th square number and the 4th cube number?
Answer:
289
Step-by-step explanation:
Simply find the fifteenth square number (225) and add it to the fourth cube number (64)
*You can find the cube by multiply 4 three times as we are looking at thr fourth cube number
The sum of square of number 15 and cube of number 4 is 289.
What is square?Square is a mathematical operation in which a number multiply with itself 2 times.
The square of number 15 = (15)²=225
The cube of number 4= 4³=64

9x +25+3x = 34 + 54
HELP!!!
Answer:
9x + 25 + 3x = 34 + 54
9x + 3x = 12x
34 + 54 = 88
12x + 25 = 88
- 25 - 25
12x = 63
x = 5.25
Answer:
x = 21/4 = 5 1/4
Step-by-step explanation:
9x +25+3x = 34 + 54
Combine like terms
12x+25 = 88
Subtract 25 from each side
12x+25-25 = 88-25
12x =63

Answer here
I
Answer:
We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.
Answer:
x = -7
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Add 11 to both sides:
x + (-11) = -18
x - 11 = -18
x - 11 (+11) = -18 (+11)
x = -18 + 11
Simplify. Combine like terms:
x = -18 + 11
x = -7
x = -7 is your answer.

You pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose 1 point. 2 lines connect and go up to the right and down to the right. The line that goes up to the right points to Ace, and the line that goes down to the right points to Not an ace. StartFraction 4 Over 52 EndFraction is above the lines, and StartFraction question mark Over 52 EndFraction is below the lines. Write the equation for the expected value. E(V) = 4 52 (a) + b 52 (c) a = b = c =
The equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
How to determine the equation of the expected valueIn a standard deck of cards, there are:
Ace = 4
Cards = 52
So, the probability of selecting an ace is:
[tex]p = \frac{4}{52}[/tex]
Simplify
[tex]p = \frac{1}{13}[/tex]
The probability of not selecting an ace is calculated using the following complement rule
[tex]q = 1 - \frac{1}{13}[/tex]
Simplify
[tex]q =\frac{12}{13}[/tex]
The expected value is then calculated as:
[tex]E(x) = \sum x * P(x)[/tex]
This gives
[tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
Hence, the equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]

Answer:
32 degrees.
Step-by-step explanation:
So every triangle =180 degrees.
Firstly, 14 + 45 = 59
Secondly, 180 - 59 = 121
so angle AEB = 121 degrees.
Using vertical angles theorum, angles AEB and CED are equal to each other
so CED = 121 degrees.
121 + 27 = 148
then 180 - 148 = 32
Angle D = 32 degrees

If ABC is reflected across the y-axis, what are the coordinates of A? A (1-3)
B. (-1, -3)
C. (5,-3)
D. (-1,3)
Answer:
d. (-1, 3)
Step-by-step explanation:
Reflecting across y axis means the x coordinate will change.
Imagine a mirror image of the triangle on the other side of Y axis.
A's coordinates on the right are (1, 3)
So if we flip across Y the coordinates will now be (-1, 3)
3 stays the same because it is still in the same position vertically.
The correct option will be Option B: When ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).
What is reflection?Reflection is the transformation of the picture about an axis so that the distance of the reflected image from the axis is the same as the distance of the original image from the axis.
When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Given that the triangle ΔABC is reflected across the y-axis.
The coordinate of point A is (1,-3).
When point A of triangle ΔABC is reflected by the y-axis, then the coordinate of y will not change. The mirror image of the triangle will be on the other side of the y-axis.
As we know When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Then the coordinate of the reflected point A will be (-1,-3).
Therefore when ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).

A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?
Answer:
The height of the hovercraft at the time of takeoff is 33 meters.
Step-by-step explanation:
Height of hovercraft x seconds after takeoff = h(x) = -(x - 11)(x + 3)
Height after takeoff is = h(0) = -(0 - 11)(0 + 3) = -(-11)(3) = 33
So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.

First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.
[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]
Now let's find the area.
