Answer:
C.) 5.1
Step-by-step explanation:
First, solve for J's angle of degrees
180 - (120 + 40) = 20
Second, fill in all the information that you know in the equation
sin(20) / 2 and sin(120) / k
Third, cross multiply
k x sin(20) = 2 x sin(120)
Fourth, solve for k
k x sin(20) / sin(20) = [2 x sin(120)] / sin(20)
k = [2 x sin(120)] / sin(20)
k = 5.0641777.....
Fifth, round to the nearest tenth
k = 5.1

How does -1.125 + 1.2 = 0.075 instead of 0.925?
Answer:
.0075 (hope this help; let me know if not)
Step-by-step explanation:
The operation is + and the signs of the numbers are opposite so we have to subtract. The bigger number has positive sign in front if so we do 1.2-1.125=1.200-1.125
I'm going to line up

What is the slope of (-1, 6) and (2, -3)
Answer:
Slope = -3
Step-by-step explanation:

20 Points! if pencils cost $2.40 for twelve, what is the unit price per pencil?
Answer:
$0.20
Step-by-step explanation:
A dozen of pencils = $2.40
1 pencil = $2.40 ÷ 12 = $0.20
PLEASE DO MARK ME AS BRAINLIEST UWU
ALSO, DO HAVE A GREAT DAY ;)
The unit price per pencil is determined by dividing the total cost of the pencils ($2.40) by the total number of pencils (12), giving a result of $0.20 per pencil.
Explanation:To find the unit price per pencil, you would divide the total cost by the total number of items.
In this case, the total cost is $2.40 and there are twelve pencils, so the calculation is $2.40 ÷ 12.
This will give you the unit price per pencil.
Using the numbers provided, $2.40 (the total cost) divided by 12 (the total number of pencils) equals $0.20.
So, the unit price of a pencil is $0.20.

When solving for x, the sine of 44º is used. What other angle and trigonometric function could be used to solve for x? a. tan 46º c. tan 44º b. cos 46º d. cos 44º
Answer:
cos46°
Step-by-step explanation:
Using the co function identity
sin x° = cos(90 - x)°, hence
sin44° = cos(90 - 44)° = cos46°
Answer: The correct option is (b) cos 46°.
Step-by-step explanation: Given that when solving for x, the sine of 44º is used.
We are to select the other angle and trigonometric function that could be used to solve for x.
We know that,
the sine of any acute angle is equal to the cosine of its complement.
That is,
if y denotes the measure of any acute angle, then we have
[tex]\sin y=\cos(90^\circ-y).[/tex]
Therefore, if y = 44°, then we get
[tex]\sin 44^\circ=\cos(90^\circ-44^\circ)=\cos 46^\circ.[/tex]
Thus, the other angle and the trigonometric function that could be used to solve for x is cos 46°.
Option (b) is CORRECT.

Which of the following constants can be added to x^2 - 3x to form a perfect square trinomial?
A. 1 1/2
B. 2 1/4
C. 4 1/2
Answer:
B.2 1/41
Step-by-step explanation:
In a perfect square trinomial of the form ax+bx+c where a, b and c are constants, the value of (b/2)²=ac
In the provided equation the value of a=1, b=-3 c=?
Therefore, (-3/2)²=c since a-the coefficient of x²=1 and 1×c=c
c=2.25= 2 1/4
Thus the trinomial x² - 3x + 2 1/4 is a perfect square.

Please help I’m stressed and I wanna cry MATH IS ANOTHER LANGUAGE TO ME
Answer: X+5
Step-by-step explanation:
When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.
I hope this helps :)
The greatest common factor (GCF) of the numerator 9x+45 and the denominator x^2 +9x+20 of the provided rational expression is x+5.
Explanation:The greatest common factor (GCF) is found by factoring both the numerator and the denominator and then identifying the largest factor that appears in both. For the provided rational expression 9x+45 over x2 +9x+20, let's factor both parts:
Numerator: 9x+45 can be factored out as 9(x+5).Denominator: x2 +9x+20 can be factored into (x+4)(x+5).Comparing both factored forms, we can see that x+5 appears in both the numerator and the denominator, and it is the largest factor common to both. Therefore, the GCF of the numerator and the denominator is x+5.
The product of a fraction and the sum of 5 1/3 and 6 1/3 is 3. What is the fraction?
Answer:
The fraction = 9/35
To find the fraction, calculate the sum of 5 1/3 and 6 1/3, which is 35/3, then divide the final product, 3, by this sum. The fraction that when multiplied by the sum equals 3 is 9/35.
The question asks us to find the fraction when the product of the fraction and the sum of 5 1/3 and 6 1/3 is 3.
First, let's calculate the sum of 5 1/3 and 6 1/3:
5 1/3 can be written as (5*3 + 1)/3 = 16/3.
6 1/3 can be written as (6*3 + 1)/3 = 19/3.
Adding these fractions, we get (16/3) + (19/3) = (35/3).
So, we have the equation:
Fraction imes (35/3) = 3
To find the unknown fraction, we divide both sides by 35/3:
Fraction = 3 / (35/3) = 3 imes (3/35) = 9/35
Therefore, the fraction we are looking for is 9/35.

What’s the median of the data 24,2,13,12,2,5,10,18
Answer:
11
Step-by-step explanation:
arrange from smallest to greatest:
2,2,5,10,12,13,18,24
The median is the middle name.
If you have two middles, the median is the average of them.
So you have 2 middles, 10 and 12.
The average of 10 and 12 is given by (10+12)/2=11
Hello There!
The median is the middle number of the data set so let’s find it!
Step 1. Order your numbers from least to greatest so after we have done that, our numbers would be 2,2,5,10,12,13,18,24
Step 2. We want to cross of a number at the beginning so Starting with 2 and the last number 18 and do that either until we get to one number in the middle or two numbers.
Step 3. There is no one number in the middle but we have the numbers 10 and 12 so we add them together which gives us a sum of 22 and then divide 22 by 2 and we get a quotient of 11.
Our median is 11.

Answer:
D. 76.5
Step-by-step explanation:
The summation sign means that it is the sum of the expression for all values of n upto 6.
n = 2 below the summation sign means that n starts from 2.
∑(n-1)!/2 from n= 2 to n=6
= (2-1)!/2 + (3-1)!/2 + (4-1)!/2 + (5-1)!/2 + (6-1)!/2
= 1!/2 + 2!/2 + 3!/2 + 4!/2 + 5!/2
= 1/2 + 2*1/2 + 3*2/2 + 4*3*2/2 + 5*4*3*2/2
= 1/2 + 2/2 + 6/2 + 24/2 + 120/2

What is the frequency of the function f(x)?
f (x) = 3 cos (TX) – 2
Express the answer in fraction form.
Answer:
Frequency = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
We are given the following function and we are to find its frequency:
[tex]f (x) = 3 cos (\pi x) -2[/tex]
We know that the standard form of cosine function is [tex]y=Acos (Bx)+c[/tex]
where [tex]A[/tex] is the amplitude, [tex]B=\frac{2\pi}{\text{Period}}[/tex] while [tex]c[/tex] is the mid line.
Frequency is given by:
[tex]F=\frac{1}{P}[/tex] where [tex]F[/tex] is frequency and [tex]P[/tex] is the period.
Finding period by comparing the given function:
[tex]y=3cos(\pi x)-2[/tex]
[tex]Period - B = \pi[/tex]
Substituting B to get:
[tex]\pi =\frac{2\pi}{\text{Period}}[/tex]
[tex]\text{Period}=\frac{2\pi}{\pi}=2[/tex]
So, Period = 2.
Since frequency is [tex]\frac{1}{P}[/tex], therefore
Frequency = [tex]\frac{1}{2}[/tex]
The frequency is T / (2π).
To find the frequency of the function f(x) = 3 cos(T x) – 2, start by recognizing the standard form of a cosine function, which is f(x) = A cos(Bx + C) + D. Here, A, B, C, and D are constants with specific roles.
The frequency is found using the parameter B in the form Bx. The angular frequency B is equal to T in our function. Frequency (f) is related to angular frequency (ω) by the formula:f = ω / (2π)
Since ω = T:f = T / (2π)
Therefore, the frequency of the function f(x) = 3 cos(Tx) – 2 is T / (2π).

to create an all purpose cleaning product, 1.5 ounces of cleaner must be added to one gallon of water. How many ounces of cleaner will be added to 8.5 gallons of water?
Answer:
12.75 oz
Step-by-step explanation:
1 gallon is equivalent to 64 oz.
Writing and solving an equation of ratios, we get:
1.5 oz 1 gal
----------- = ------------
x 8.5 gal
Here we must cross-multiply to solve for x.
x(1 gal) = (1.5 oz)(8.5 gal) = 12.75 oz
Thus, x = 12.75 oz of cleaning product must be added to 8.5 gal of water to create the desired solution.
To make an all-purpose cleaner, you need 12.75 ounces of cleaner for 8.5 gallons of water.
This is determined by multiplying the ratio of 1.5 ounces per gallon by 8.5 gallons.
follow these steps:
First, determine the ratio of cleaner to water. The ratio is 1.5 ounces of cleaner per gallon of water.Next, multiply this ratio by the number of gallons to find the total amount of cleaner needed for 8.5 gallons of water.Calculate: 1.5 ounces/gallon * 8.5 gallons = 12.75 ounces.Therefore, 12.75 ounces of cleaner will be added to 8.5 gallons of water.
