Step-by-step explanation:
At BBQ Shack they only sell ribs, the cost of a half rack x is $10 and the cost of a full rack y is
$20. The manager's goal for the day is to have at least 25 customers buy ribs, and to have
total sales be greater than $300. Write a system to represent this situation.
Answer:
300=10x+20y
Step-by-step explanation:
You are trying to get the sales to equal 300 so the 10x and 20y added together will get you 300

What is the measure of angle z?
137 because they are 180 angles so you subtract 180-43=137.
Answer:
so in this figure the 43°=y°(by vertical opposite angle)
y°+z°=180°(by linear pair)
43°+z°=180°
z=180°-43°
z=137°

Jane drew a point that was 3 units to the right of the y-axis and 5 units above x-axis what ordered pair for this location
Answer:
(3,5)
Step-by-step explanation:
If you imagine a grid in your head, moving 3 units to the right is the same as 3 on the x axis, and 5 units above the x axis is the same as 5 on the y axis. X goes before y in an ordered pair, so the answer would be (3,5). Hope this helps!!

Answer:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big) = \frac{7\sqrt{58} }{ 58 }[/tex]
[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\frac{3 \sqrt{58}}{58}[/tex]
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=-\frac{7}{3}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \sin(x)=-\frac{21}{29}[/tex]
Where x is in QIII.
First, recall that sine is the ratio of the opposite side to the hypotenuse. Therefore, the adjacent side is:
[tex]a=\sqrt{29^2-21^2}=20[/tex]
So, with respect to x, the opposite side is 21, the adjacent side is 20, and the hypotenuse is 29.
Since x is in QIII, sine is negative, cosine is negative, and tangent is also negative.
And if x is in QIII, this means that:
[tex]180<x<270[/tex]
So:
[tex]\displaystyle 90 < \frac{x}{2} < 135[/tex]
Thus, x/2 will be in QII, where sine is positive, cosine is negative, and tangent is negative.
1)
Recall that:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\pm\sqrt{\frac{1 - \cos(x)}{2}}[/tex]
Since x/2 is in QII, this will be positive.
Using the above information, cos(x) is -20/29. Therefore:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{1 + 20/29}{2}[/tex]
Simplify:
[tex]\displaystyle \sin\Big(\frac{x}{2}\Big)=\sqrt{\frac{49/29}{2}}=\sqrt{\frac{49}{58}}=\frac{7}{\sqrt{58}}=\frac{7\sqrt{58}}{58}[/tex]
2)
Likewise:
[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =\pm \sqrt{ \frac{1+\cos(x)}{2} }[/tex]
Since x/2 is in QII, this will be negative.
Using the above information, cos(x) is -20/29. Therefore:
[tex]\displaystyle \cos \Big( \frac{x}{2} \Big) =-\sqrt{ \frac{1- 20/29}{2} }[/tex]
Simplify:
[tex]\displaystyle \cos\Big(\frac{x}{2}\Big)=-\sqrt{\frac{9/29}{2}}=-\sqrt{\frac{9}{58}}=-\frac{3}{\sqrt{58}}=-\frac{3\sqrt{58}}{58}[/tex]
3)
Finally:
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big) = \frac{\sin(x/2)}{\cos(x/2)}[/tex]
Therefore:
[tex]\displaystyle \tan\Big(\frac{x}{2}\Big)=\frac{7\sqrt{58}/58}{-3\sqrt{58}/58}=-\frac{7}{3}[/tex]

the set of all possible input values for a function is called the domain of the function, and the set of all output values for a function is called the range. ... The y variable is the dependent variable and represents the corresponding output value f (x) in the rang
The population of a small town was 10,800 in 2003. Since then, the population has
decreased at a rate of 2.5% each year. What is the population of the town in 2021?
Answer: 5940
Step-by-step explanation: I don't know if it's for sure right but here
First I knew 10,800 was 100% and I wanted to find 2.5%
So I did:
10,800 divided by 100 and I got 108 = 1%
Than you want to do
108 x 2.5 = 270 ( 2.5% )
After that you wanted to find out how much years apart so
2021 - 2003 = 18
Then
18 x 270 = 4,860
Last of all you have to do
10,800 - 4,860 = 5940

The triangles shown are congruent. What is a correct congruence statement for the triangles shown? Enter your answer in the box. △ ≅△NKW A triangle U Z E is made. Another triangle N K W is drawn. The sides Z E and K W are marked equal. The angle U Z E and angle N K W are labeled with a single tick mark. The angle Z E U and angle K W N are labeled with a double tick mark.
ΔUZE ≅ △NKW by angle side angle postultue of congrency.
What is congruence?If two figures are exactly the same in sense of their length side all things then they will be congruent.
In other meaning, if you can copy a figure then that copy and the original figure will be congruent.
As per the given △NKW.
m∠K = m∠Z
Side KW = side ZE
m∠W = m∠E
Thus, by angle side angle theorem both triangles will be congruent.
Hence "ΔUZE ≅ △NKW by angle side angle postulate of congruency".
