A right triangle has a hypotenuse with length 13 in. and a leg with length 12 in. Find the area of triangle
Answer:
[tex]30 {in}^{2} [/tex]
Step-by-step explanation:
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.
[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 5 \times 12 \\ = \frac{60}{2} \\ = 30 {in}^{2} [/tex]

Answer:
58.9 ft²
Step-by-step explanation:
The horse is constrained to 3/4 of a circle that has a 5 ft radius. Then the area is ...
A = (3/4)πr²
A = (3/4)π(5 ft)² = 75π/4 ft²
A ≈ 58.9 ft²
The horse has a maximum grazing area of 58.9 ft².
_____
In the real world, a 5 ft rope is awfully short. The grazing area would depend on how high on the barn it is tied, and where on the horse it is tied.

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4pi units. The base of cylinder B has an
area of 9pi units.
The dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B?
4/9 2/3 3/2 9/4
Answer:
d) 9/4
Step-by-step explanation:
Explanation:-
Given circumference of cylinder A = π r² = 4π units
Given circumference of cylinder B = π r² = 9π units
The dimensions of cylinder A are multiplied by [tex]\frac{9}{4}[/tex]
circumference of cylinder A = π r² = 4π([tex]\frac{9}{4})[/tex] units = 9 π units
circumference cylinder A= 4π([tex]\frac{9}{4})[/tex] units = 9 π units = circumference of cylinder B
Final answer:-
The dimensions of cylinder A are multiplied by 9/4 produce the corresponding dimensions of cylinder B

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

Step-by-step explanation:
if u want to find the width u need to divide
area equals l times w
w equals area divided by l
l equals area divided by w
we need to find width
so w= 5451 divided by 79

The list below shows all of the possible outcomes for flipping four coins. HHHH HHHT HHTH HHTT HTHH HTHT HTTH HTTT THHH THHT THTH THTT TTHH TTHT TTTH TTTT What is the probability of at least two coins landing on heads? StartFraction 5 over 16 EndFraction StartFraction 3 over 8 EndFraction One-half StartFraction 11 over 16 EndFraction
Answer:
d
Step-by-step explanation:
The solution is Option D.
The probability of at least two coins landing on heads is given by the equation P = 11/16
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability of at least two coins landing on heads be P
Now , the equation will be
Let the coin landing on its head be represented as = H
Let the coin landing on its tail be represented as = T
The possible outcomes of flipping a coin be represented by set A
Set A = { HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , HTTT , THHH , THHT , THTH , THTT , TTHH , TTHT , TTTH , TTTT }
So ,
The total number of outcomes = 16 outcomes
The number of outcomes where at least 2 coins land on their heads is given by set B
Set B = { HHHH , HHHT , HHTH , HHTT , HTHH , HTHT , HTTH , THHH , THHT , THTH , TTHH }
The number of outcomes of set B = 11
So , the probability of at least two coins landing on heads be P = number of outcomes of set B / total number of outcomes
Substituting the values in the equation , we get
Probability of at least two coins landing on heads be P = 11/16
Therefore , the value of P is 11/16
Hence , the probability is 11/16

which linear inequality is represented by the graph?
Answer:
the second one
Step-by-step explanation:
The y-intercept is -4 so we can eliminate the third and fourth options. Substitute (0,0) into the equation and from that we can say that it is not true (0 is not less than -4). Because it isn't true, we shade in the side that doesn't have the origin in it.
Seven different names were put into a hat. A name is chosen 106 times and the name Josh is chosen 19 times. What is the THEORETICAL probability of the name Josh being chosen?
HELPPPPPPPP
We will see that the theoretical probability that the name Josh is chosen is P = 1/7.
How to find the theoretical probability?7 names are put on a hat, theoretically, we assume that all the names have the same probability of being randomly drawn from the hat. So it does not depend on the given information, that would give us the experimental probability.
Then, for the theoretical probability we will have the quotient between the number of names in the hat that are Josh (there is only one) and the total number of names in the hat, this gives:
P(Josh) = 1/7

The length of the hypotenuse of a 30-60-90 triangle is 4. find the perimeter
Answer:
Answer is B
Step-by-step explanation:
The hypotenuse of a triangle is always twice the length of the shorter side in a 30 60 90 triangle. So if the hypotenuse is 4 the shortest side must be 2. Meaning the sum will be 6. The medium side is the shortest side times the square root of 3. So we have 2[tex]\sqrt{3}[/tex]. Our final equation is 6+ 2[tex]\sqrt{3}[/tex].

A microscope dilates the image of an organism 4 times its original dimensions. If the radius of a circular organism seen by the microscope is 8 cm, find the radius of the actual organism. Question 17 options: A) 4 cm B) 8 cm C) 2 cm D) 32 cm
Answer: 2cm
Step-by-step explanation:
From the question, we are informed that a microscope dilates the image of an organism 4 times its original dimensions and that the radius of a circular organism has seen by a microscope is 8 cm.
Since the microscope makes the objects 4 times bigger, then the original radius will be:
= 8cm/4
= 2cm
The radius of the actual organism is 2cm.

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).

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]
