Answer:
x=14
Step-by-step explanation:
The angles inside a triangle add up to 180 degress all the time, therefore
58+80+3x=180
simplify
138+3x=180
subtract 138 from both sides of the equation
3x=42
divide both sides by 3
x=14

234 students in 9 different classrooms. What is the ratio of students to classrooms?
Answer:
26 students per classroom
Step-by-step explanation:
To solve this, the ratio 234 students:9 classrooms must be converted to:
s students:1 classroom
To convert the ratio, 9 was divided by 9 to get 1, and so you must also divide 234 by 9 to maintain the same ratio, which gives us the answer:
26 students: 1 classroom

Answer:
R=34
Step-by-step explanation:
As, pythoreon therom states = a2 + b2= c2
a= 16, 16^2 = 256
b= 30, 30^2 = 900
c2= 900+256
c2 = 1,156
c= 34
So, 16^2 + 30^2 = 34^2

PLEASE HELP Find the product of( -3-2i ) and it’s conjugate.
the question is in the picture. it’s math.
Answer:
Step-by-step explanation:
1). (8x - 49)° = (5x + 23)°
8x - 49 = 5x + 23
3x = 72
x = 24
2). m∠VST + m∠SVU = 180°
(5(24) + 23)° + m∠SVU = 180°
m∠SVU = 180° - 143°
m∠SVU = 37°
m∠SVT = 37° - 20° = 17°

Part 2
Answer:
Before we graph [tex]y = -\frac{1}{2}x,[/tex] we know that the slope, mx, could be read as [tex]\frac{rise}{run}[/tex]. To graph the the equation of the line, we begin at the point (0,0). From that point, because our rise is negative (-1), instead of moving upwards or vertically, we will move downards. Therefore, from point 0, we will vertically move downwards one time. Now, our point is on point -1 on the y-axis. Now, we have 2 as our run. From point -1, we move to the right two times. We land on point (2,-1). Because we need various points to graph this equation, we must continue on. In the end, the graph will look like the first graph given.
For the equation y = 2, the line will be plainly horizontal. Why? Because x has no value in the equation. The variable [tex]x[/tex] does not exist in this linear equation. Therefore, it will look like the second graph below. We graph this by plotting the point, (0,2), on the y-axis.
factor completely6x2+8x+2. Fill in the blanks using the correct sign: 2(3x+ )(x+ )
Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
2(3x + 1)(x + 1)
Step-by-step explanation:
Given
6x² + 8x + 2 ← factor out 2 from each term
= 2(3x² + 4x + 1) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × 1 = 3 and sum = 4
The factors are + 3 and + 1
Use these factors to split the x- term
3x² + 3x + x + 1 ( factor the first/second and third/fourth terms )
= 3x(x + 1) + 1(x + 1) ← factor out (x + 1) from each term
= (3x + 1)(x + 1) , then
3x² + 4x + 1 = (3x + 1)(x + 1)
and
6x² + 8x + 2 = 2(3x + 1)(x + 1) ← in factored form
A program was created to randomly choose customers at a shoe store to receive a discount. The program claims 15% of the receipts will get a discount in the long run. The manager of the shoe store is skeptical and believes the program's calculations are incorrect. She selects a random sample and finds that 12% received the discount. The confidence interval is 0.12 ± 0.05 with all conditions for inference met.
Part A: Using the given confidence interval, is it statistically evident that the program is not working? Explain.
Part B: Is it statistically evident from the confidence interval that the program creates the discount with a 0.15 probability? Explain.
Part C: Another random sample of receipts is taken. This sample is six times the size of the original. Twelve percent of the receipts in the second sample received the discount. What is the value of margin of error based on the second sample with the same confidence level as the original interval?
Part D: Using the margin of error from the second sample in part C, is the program working as planned? Explain.
Answer:
A: There is no statistical evidence that the program is not working as intended because 0.15 is between the range of 0.12 ± 0.05 = (0.07,0.17)
B: 0.15 is between the range of (0.07,0.17) so it is statistically probable.
C: margin of error=0.05/((6)^(1/2))=0.0204
D: No the program is not working as planned because 0.15 is not within the range of 0.12±0.0204=(0.0996,0.1404)

Donte ordered the plans shown to build a skateboard ramp. Each unit represents one foot. He wants to keep the same slope of the ramp and extend the base of the triangle three feet. How tall will the ramp be
Answer:
3 feet
Step-by-step explanation:
The slope of line shows the steepness of that line. It is the ratio of the change in vertical distance to the change in horizontal distance.
The slope of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is:
[tex]slope=\frac{change\ in\ y}{change\ in\ x}=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the diagram of the ramp, we can see that:
The ramp passes through the point (0,0) and (6, 2). Therefore the slope is:
[tex]slope=\frac{2-0}{6-0}=\frac{1}{3}[/tex]
The base is at 6 ft tall, if we extend the base by 3 units, the base would be 9 ft (6 + 3). The new height would be:
height = slope * base = (1/3) * 9 = 3 feet
If the base is extended by 3 feet, the tall would be 3 feet tall.

How much would it cost to get exactly three bottles of lemonade using this offer?
Answer:
114p
Step-by-step explanation:
I did the math, I really hope it's correct
The cost to get exactly three bottles of lemonade using the offer will be [tex]190p[/tex] .
What is expression ?Expressions is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have,
Normal price of bottle [tex]=76p[/tex]
And,
Offer is buy one get one half price.
So,
According to the question,
Normal price of one bottle [tex]=76p[/tex]
Half price of one bottle [tex]=\frac{76p}{2}=38p[/tex]
So,
Price of three bottles [tex]=76*2+38[/tex]
