Solve for x
A )180
B)55
C)115
D)82.5
Answer:
55
Step-by-step explanation:
AB // DC
∠B + ∠C = 2x + 15 + x = 180
3x = 165
x = 55
Answer: B. 55
Step-by-step explanation:
You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.
---------------------------------------------------------------------------------------
Given
(2x+15)+x=180
Expand parenthesis
2x+15+x=180
Combine like terms
3x+15=180
Subtract 15 on both sides
3x+15-15=180-15
3x=165
Divide 3 on both sides
3x/3=165/3
x=55
Hope this helps!! :)

14. Write the equation in slope-intercept form that passes through the two points.
(1, 2) and (3,-8)
Answer: y=5x+7
Step-by-step explanation:
If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt form is y=mx+b. So the equation is y=5x+7.
Answer:
let (x1,y1)=(1, 2)
and(x2,y2)=(3,-8)
Step-by-step explanation:
we have
y-y1=(y2-y1)(x-x1)/(x2-x1)
y-2=(-8-2)(x-1)/(3-1)
y-2=-10(x-1)/2
y-2=-5(x-1)
y-2=-5x--5
y+5x=5+2
5x+y=7 is the required equation.note :-×-=+

Sandra wrote the sequence shown:
7, 14, 25, 40, 59
Complete each of the 2 activities for this Task.
Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.

PLEASE HELP, I need this test done and something not failed. I dont understand.
Answer:
XVW and WVT
Step-by-step explanation:
Two angles are supplementary angles when the sum of their measures is equaled to 180 degrees.
180 degrees = a line.
YVZ and WVU are Vertical Angles
YVZ and ZVT are not straight lines together.
XVW and WVU are on the same straight line but you have to add UVT in order to get 180.
XVW and WVT are the only ones that look like they can add up to 180 degrees.
XVW and WVT should be the answer, I really hope this helps!

The perimeter of a quadrilateral garden is 4x2+3x-4. The first side is represented by x2+2x+15. The second and third sides are each represented by x2-x-10. What expression represents the fourth side? Write a justification of your result.
Answer:
[tex]y = x^{2} + 3x + 1[/tex]
Step-by-step explanation:
Perimeter equals the sum of the lengths of the sides.
Let y = the length of the fourth side
[tex]4x^{2} + 3x - 4 = x^{2} + 2x + 15 + x^{2} -x - 10 + x^{2} - x - 10 + y[/tex]
[tex]4x^{2} + 3x - 4 = 3x^{2} - 5 + y[/tex]
[tex]x^{2} + 3x + 1 = y[/tex]
A bakery uses 44 cups of flour to make 10 loaves of bread. How many cups of flour are there per loaf?
Answer: 4.4
Step-by-step explanation:
44 divided by 10
Answer:
4.4 cups of flour
Step-by-step explanation:
You would have to divide 44(cups of flour) by 10(loaves of bread) to get the amount of cups of flour for each loaf. 44/10=4.4
Find the equation of the line whose slope is 1/3
and goes through the point (3, 1).
A. y= 1/3x
B. y= 1/3x + 1
C. y= 1/3x + 2
D. y= 1/3x + 8/3
Answer:
It means that when x = 3, y = 1, obviously when the first function expression takes 3, y = 1
Solve the inequality for x.
22 >x-5
Answer:
x < 27
Step-by-step explanation:
22 > x - 5
Subtract x from both sides.
-x + 22 > -5
Subtract 22 from both sides.
-x > -27
Divide both sides by -1. Remember that when you multiply or divide an inequality by a negative number, the inequality sign changes direction.
x < 27

Answer:
the fourth which passed through (0;2)
Answer:
graph 4
Step-by-step explanation:
If the slope is positive then the graph is linear increasing function.
If the slope is negative then the graph is linear decreasing function.
Graph 1) slope = 4/3
Graph 4) slope = -3/2
So, Graph 4 is linear decreasing function.

In a right angled triangke abc the perpendicular and the base measure 3 cm find hypotenus and three trignometrice ratios
Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Use Pythagoras theorem in triangle ABC.
[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]
[tex]Hypotenuse^2=9+9[/tex]
[tex]Hypotenuse=\sqrt{18}[/tex]
[tex]Hypotenuse=3\sqrt{2}[/tex]
The three trigonometric ratios are
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]
Similarly,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]
And,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\tan \theta=\dfrac{3}{3}[/tex]
[tex]\tan \theta=1[/tex]
Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].
An acting school claims that 71% of its graduates land major acting roles within one year of graduation. A random sample of 50 graduates was surveyed, and 30 of them had landed major roles within one year of graduation. Let p hat = the proportion of the sample who had landed major roles within one year of graduation.
The probability that 60% or fewer graduates land a major acting role within one year of graduating from this school is 0.043. Does this result provide convincing evidence against the school’s claim?
A. Yes, it is expected that at least 60 graduates from this school will land a major role within one year of graduation.
B. Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely (0.043 < 0.05).
C. No, the difference between the sample proportion and the parameter is 11%, which is greater than 5%.
D. No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely (0.043 < 0.05).
Answer:
B
Step-by-step explanation:
EDGE2021!! since the actual probability is smaller than .05, we have evidence against the acting school claiming that 71% of its graduates land major acting roles within one year of graduation.

Tory read her book and rate of 4/5 of a chapter her 2/3 of an hour. How many chapters can she read in one hour
Answer: She can read 1.2 chapters of her book in one hour.
Step-by-step explanation:
When we have a relation of: "doing something" in a given "amount of time"
The rate at which you can do that activity per unit of time is:
R = (how much you did)/(time it took)
In this case, we know that
"Tory reads 4/5 of a chapter in 2/3 of an hour"
Then the rate, in this case, could be calculated as:
R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.
This means she can read 1.2 chapters of her book in one hour.
