The legs are congruent , that is
BC = AD = 15 units
The upper base angles are congruent , so
∠ B = ∠ A = 145°
Any lower base angle is supplementary to any upper base angle, that is
∠ C + ∠ B = 180°
∠ C + 145° = 180° ( subtract 145° from both sides )
∠ C = 35°
The lower base angles are congruent , so
∠ D = ∠ C = 35°

Answer:
63 square inches
Step-by-step explanation:
You already have the polgygon divided into two rectangles, so we will use them.
The top rectangle has the dimensions of 5 and 9.
The bottom rectangle has the dimensions of 6 and 3.
To find the area of a rectangle:
area = length x width
A = lw
The area of the top rectangle:
A = 5 x 9
A = 45 square inches
The area of the bottom rectangle:
A = 6 x 3
A = 18 square inches
To find the total area, add the two areas together.
45 + 18 = 63 square inches

final answer
[tex]\rightarrow \sf \dfrac{1}{3}[/tex]
Answer:
the slope of the line passing through (-3,0) (3,2) is 1/3
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run. m=change in y/change in x. The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise). m=y2-y1/x2-x1. Substitute in the values of x and y into the equation to find the slope. m=2−(0)3−(−3)m=2-(0)3-(-3) Simplify. m=13

With the equation of the circle that has a center at the origin and passes through the point (1-6),
Answer:
[tex]\sf x^2+y^2=37[/tex]
Step-by-step explanation:
Equation of a circle: [tex]\sf(x-h)^2+(y-k)^2=r^2[/tex]
where (h, k) is the center and r is the radius
Given the center is at (0, 0)
[tex]\sf \implies (x-0)^2+(y-0)^2=r^2[/tex]
[tex]\sf \implies x^2+y^2=r^2[/tex]
Given the circle passes through point (1, -6):
[tex]\sf \implies (1)^2+(-6)^2=r^2[/tex]
[tex]\sf \implies r^2=37[/tex]
Therefore, the equation of the circle is:

When ranking candidates running for office, describe how it would or would not be possible for a voter to give two people the same rank.
It would be possible to give two people the same rank, as it is always possible to have a tie-breaker vote if two candidates are ranked the same by all voters.
It would be possible to give two people the same rank, as there are so many votes generated during the election that one vote giving two people the same rank would not make a difference.
It would not be possible to give two people the same rank, as ranking candidates means that one and only one candidate is given a specific rank.
It would not be possible to give two people the same rank, as the reason candidates are ranked is to make sure there are no ties.
Answer:
I believe it is Option C.
Step-by-step explanation:
There has only been one single tie since the passing of the 12th Amendment. It is a very low chance for a possible tie to take place, so they would have no reason to ensure it doesn't happen as it's already unlikely, ruling out option D. Giving two people the same rank would definitely make a difference as you are basically adding not 1, but two votes. Though it would even the count out, each person would gain 1 point, so it would make a difference. Option B is ruled out. This also potentially explains debunking A as there's no possible way to plan a tie to that extent. Again. ties happen very rarely, so it would be unlikely that voting for both candidates would impact the choice at all.
find the value of X to the nearest tenth
Answer:
x = 22.6 degrees
Step-by-step explanation:
The triangle is a right triangle which means that you can use trigonometry to find the values for each angle.
cos(x) = opposite / hypotenouse.
So cos(x) = 12/13.
You can then solve using a calculator and find that the angle is 22.6 degrees.
The table below shows the number of people that attended a family reunion each year. (Need help ASAP)
The table of attendees in the family reunion is a linear regression
The equation of the line of best fit is y = 4.9x + 112186 attendees are expected in the 15th yearHow to draw the scatter plot?To do this, we represent the years on the x-axis and the attendees on the y-axis
See attachment for the scatter plot
The equation of the line of best fit?The scatter plot passes through the points
(0, 112) and (5, 136.5)
Start by calculating the slope, m using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (136.5 - 112)/(5 - 0)
m = 4.9
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 4.9 * (x - 0) + 112
y = 4.9x + 112
Hence, the equation of the line of best fit is y = 4.9x + 112
The attendees in the 15th yearThis means that x = 15.
So, we have:
y = 4.9 * 15 + 112
Evaluate
y = 186
Hence, 186 attendees are expected in the 15th year

Which equation has a graph that is a parabola with a vertex at (–2, 0)?
y = –2x2
y = (x + 2)2
y = (x – 2)2
y = x2 – 2

y = (x + 2)²
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:

The discounted price for milk is $____(Round to the nearest cent.)
Answer:
$2.25
Step-by-step explanation:
You have to set up a proportion to show how much the cost of milk is when discounted per gallon. 0% off, the milk would be $3.75. 40% off, the milk would be x. Now I flipped the percents because that is how much you are actually paying.
Proportion would look something like this:
3.75/100 = x/60
solve for x:
225 = 100x
x= 2.25

Under his cell phone plan, Oliver pays a flat cost of $45 per month and $3 per gigabyte. He wants to keep his bill under $60 per month. Use the drop-down menu below to write an inequality representing g, the number of gigabytes he can use while staying within his budget
Answer: g < 5
5 is the amount of gigabytes
Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.
The inequality representing the number of gigabytes Oliver can use while staying within his budget of $60 per month is:
3g + 45 ≤ 60.
where,
"g" represents the number of gigabytes used.
$3 is the cost per gigabyte.
$45 is the flat monthly cost.
$60 is the maximum budget.
Oliver pays a flat cost of $45 per month, which is represented by the constant term 45 in the inequality.
He also pays $3 per gigabyte, so the cost for the gigabytes used is 3g, where "g" represents the number of gigabytes.
The total cost (3g + 45) must be less than or equal to $60, as he wants to keep his bill under $60 per month.
Hence, the inequality is 3g + 45 ≤ 60.
Now, solve for g:
45 + 3g ≤ 60
Subtract 45 from both sides:
3g ≤ 15
Divide both sides by 3:
g ≤ 5
So, Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.

A bag contains an unknown number of marbles. You know that P(red) = 1 and P(green) = 1. What can you conclude about how many marbles are in the bag?
The number of marbles in the bag illustrates probability
The conclusion about the number of marbles in the bag is that the bag can only contain one type of marble
The number of marbles in the bag?The probabilities are given as:
P(Red) = 1
P(Green) = 1
For a distribution, the sum of all probabilities must equal to 1.
This means that:
P(Red) + P(Green) = 1
So, we have:
1 + 1 = 1
This gives
2 = 1
The above equation is false because 2 does not equal to 1.
So, the conclusion about the number of marbles in the bag is that the bag can only contain one type of marble i.e. either red marbles are in the bag or blue marbles are in the bag

Step-by-step explanation:
find x for -3 + x = 2 (x+3)
-3 + x = 2 (x + 3) <== distribute
-3 + x = 2x + 6 <== subtract 1x from both sides

Solution :

Using Distributive property for the right side we get :

Now, subtracting 2x from both sides we get :
