Find sin(b) in the triangle.
A.4/3
B.3/5
C.3/4
D.4/5
The value of [tex]\sin \beta[/tex] in the given triangle ABC is [tex]\dfrac{4}{5}[/tex]. Option D is correct.
What are the trigonometric ratios?Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.
Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.
In the given figure, the side opposite to the angle [tex]\beta[/tex] is AC = 4 and the hypotenuse is AB = 5.
So, the sine ratio will be equal to,
[tex]\sin \beta=\dfrac{4}{5}[/tex]
Therefore, the value of [tex]\sin \beta[/tex] in the given triangle ABC is [tex]\dfrac{4}{5}[/tex]. Option D is correct.

The length of a log of wood is 90 in. How many cuts do you need to make to obtain
the greatest number of pieces, where each piece will have a different length and the
length of each piece is a whole number, in inches?
The greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
The total length of the wood = 90 in
We have to cut it into the greatest number of pieces, where each piece will have a different length and the length of each piece is a whole number, in inches.
We can cut it like:
1 in, 2 in, 3 in, 4 in, and so on
The above shows the arithmetic sequence,
The sum of the n natural number is given by:
[tex]\rm S_n = \dfrac{n(n+1)}{2}[/tex]
[tex]\rm 90 = \dfrac{n(n+1)}{2}[/tex]
After solving, we will get a quadratic equation:
n² + n -180 = 0
After solving, we will get:
n = 12.92 and n = -13.92(term can not be negative)
n = 12 (taking whole number)
Thus, the greatest number of pieces will be 12 where each piece will have a different length and the length of each piece is a whole number, in inches and the remaining piece length will be 12 in(90 - 78).

What is the solution to this system of equations?
3x + 2y = -10
y = -x - 4
A. (-2,-2)
B. (-2,2)
C. (-18,14)
D. No solution
3x + 2y=-10 equation 1
y=-x -4 equation 2
use the substitution method of elimination to get the answer to the question.
*using substitution
substitute equation 2 in one and we get
3x +2(-x-4)=-10
3x- 2x-8=-10
x=-2 and y=-2
Answer:
B
Answer: Choice A
(-2, -2)
=============================================================
Explanation:
I'll use the substitution method to solve this system.
Replace y in the first equation with -x-4. This is because y = -x-4 is mentioned in the second equation.
So,
3x + 2y = -10
3x + 2( y ) = -10
3x + 2( -x-4 ) = -10 .... substitution
3x - 2x - 8 = -10
x - 8 = -10
x = -10+8
x = -2
Then use this to find y
y = -x-4
y = -(x) - 4
y = -(-2) - 4
y = 2 - 4
y = -2
We have x = -2 and y = -2 pair up together
They form the ordered pair solution (x, y) = (-2, -2)
This shows why Choice A is the answer.
Another way to see this is to graph each equation given using a tool like Desmos. It's a free graphing app.
See below.
The two lines intersect at (-2, -2) which is the solution.

Given the following: f(x) = 3x - 7; g(x) = 13- 2x; and h(x) = 6x
h(g(g(x))) equals 13æ - 9.
True
False
We will see that:
h(g(g(x)) = -78 + 24x
Which means that the statement is false.
Is the statement true?
Here we have that:
g(x) = 13 - 2x
h(x) = 6x
Now we want to find the composition of functions:
h(g(g(x))
First, let's find g(g(x)) = 13 - 2*g(x) = 13 - 2*(13 - 2x) = 13 - 26 + 4x
g(g(x)) = -13 + 4x
Now let's evaluate h(x) in that:
h(g(g(x)) = 6*g(g(x)) = 6*(-13 + 4x) = -78 + 24x
This is not equal to what we have in the question, so we conclude that the statement is false.

An elementary class consists of 8 boys and 10 girls. A child is chosen at random and it is a girl. A second child is randomly chosen again from the remaining children, and it is a boy. Was the probability of choosing the boy dependent on choosing a girl first
Answer:
Yes
Step-by-step explanation:
So we know the second child was a boy however if the first child was a boy, the probability of getting a second boy would be 7/17 since one boy is missing and one person is missing from the total.
However, if a girl was chosen as the first child, the probability of getting a boy second would be 8/17 since no boys would be missing but one person would be missing from the original total.
A recipe calls for 1 ¼ cups of sugar and 1 ¾ cups of flour to make one batch of cookies. How much sugar and flour would it take to make 3 batches of cookies?
Answer:
It will take 3 3/4 cups of sugar and 5 1/4 cups of flour.
Step-by-step explanation:
Multiply 1 1/4 and 1 3/4 by three, because 3 batches of cookies are being made.
1 1/4x3= 3 3/4 cups of sugar
1 3/4x3= 5 1/4 cups of flour
Rachel found that 20 out of 48 cars that entered a parking lot were red. What is the experimental probability that the next car that comes in is red? What is the experimental probability that the next car that comes in is not red?
In the observation of Rachel the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.
What is experimental probability?Experimental probability of an event is the ratio of number of favorable outcome which appeared while conducting an event to the total number of outcome of that event is occurred.
Rachel found that 20 out of 48 cars that entered a parking lot were red. In this observation, the probability of a car to be red is,
[tex]P=\dfrac{20}{48}\\P=\dfrac{5}{12}[/tex]
Thus, the experimental probability that the next car that comes in is red is 5/12.
The experimental probability that the next car that comes in is not red is,
[tex]P^{-1}=1-\dfrac{5}{12}\\P^{-1}=\dfrac{12-5}{12}\\P^{-1}=\dfrac{7}{12}[/tex]
Hence, In the observation of Rachel, the experimental probability of the next car which comes in is red is 5/12 and the experimental probability of the next car which comes in is not red is 7/12.

The supplement of each interior angle has measure
180° - 165° = 15°
and so

since the exterior angles add up to 360° and are all congruent.

What is the solution to the equation ?
p = –6
p =
p = –4
p =
The solution to this equation is p = -6
This expression is related to a First Degree Equation.First degree equation is a mathematical expression and sentence, which is defined by having only one unknown. Its representation is given by: ax+b=0.
— To solve this expression, let's eliminate these square root symbols:
√-5p = √24-p
-5p = 24 - p
— Move the p term before the positive sign equality, thus also shifting the 24th term:
-5p = 24 - p
-5p + p = 24
-4p = 24
— Finally, let's divide the second to the first term of this equation:
-4p = 24
p = 24 ÷ (-4)
p = -6
Therefore, the correct result of this expression will be p = -6

The area of a circle is 60.12cm find the length of the radius rounded to 2 dp.
Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi.
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
[tex]A = \pi r^2[/tex]
[tex]A[/tex] stands for Area, and [tex]r[/tex] stands for Radius
Now, plug in the given values:
[tex]60.12 = \pi r^2[/tex]
Next, replace 3.14 for pi:
[tex]60.12 = (3.14)r^2[/tex]
Then, divide both sides by 3.14 ,which gives us:
[tex]19.15 = r^2[/tex]
Please note: 19.15 is rounded
Anyway, to isolate [tex]r[/tex], we take the square root of both sides:
[tex]\sqrt{19.15} = \sqrt{x^2}[/tex]
The square root and square on the right side of the equation cancel out, and we are left with:
[tex]4.38 = r[/tex]
Please note that 4.38 was rounded
