Answers:
y = 50
angle AOB = 100
=========================================
Explanation:
Angle x is an inscribed angle that subtends or cuts off minor arc AB. This is the shortest distance from A to B along the circle's edge.
Angle y is also an inscribed angle that cuts off the same minor arc AB. Therefore, it is the same measure as angle x. We can drag point D anywhere you want, and angle y will still be an inscribed angle and still be the same measure as x.
-------------------
Point O is the center of the circle. This is because "circle O" is named by its center point.
Angle AOB is considered a central angle as its vertex point is the center of the circle.
Because AOB cuts off minor arc AB, and it's a central angle, it must be twice that of the inscribed angle that cuts off the same arc.
This is the inscribed angle theorem.
Using this theorem, we can say the following
central angle = 2*(inscribed angle)
angle AOB = 2*(angle x)
angle AOB = 2*50
angle AOB = 100 degrees

In the figure below, triangle ABC is similar to triangle PQR, as shown below.
What is the length of side PQ? (1 point)
a-33
b-34
c-35
d-36
Answer: 36
Step-by-step explanation:
As you can see, side AB is similar with side PQ.
Also, side BC is similar with side QR.
If you divide the length of side QR (34.5) by the length of side BC (11.5)
you get 3.
3 is the ratio that you will use to find the other side. The ratio of triangle ABC to PQR is 1:3
Multiply the side of AB (12) by 3 and you will get 36.
The measure of side PQ in triangle PQR is 35 units. Therefore, option D is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle ABC is similar to triangle PQR.
By similar triangles statement, we have
AB/PQ = BC/QR
12/PQ = 11.5/34.5
12×34.5=PQ×11.5
11.5PQ=414
PQ=414/11.5
PQ=36
Therefore, option D is the correct answer.

rs. Young is buying tshirts for her students in a class. There are 24 students in her class. Each student will pay $9.50 for their shirts. During the first week, 15 students paid. The remaining students paid the second week. How much money will be collected on the second week?
Answer:
The answer is $85.50
Step-by-step explanation:
You have to multiple the number of students that are paying on the second week, which is 9 by $9.50, then you'll get $85.50
WEEK ONE --
9.50 x 15 = $142.5 (15 out of 24 students)
--
WEEK TWO --
9 x 9.50 = $85.5 (9 out of 24 students)
--
$85.5 will be collected on the second week.
10. What are the break-even points of the profit function (the values of x where profit equals 0)? Use the quadratic formula. (4 points: 2 points for each x-value)
Answer:
r = 50000
P (r) = 0.7r - 35000
Step-by-step explanation:
Given cost function is
C (r) = 0.85r + 35000
and revenue function is
R (r) = 1.55r
At break even point, revenue is equal to cost
R(x)= C(x)
1.55r = 0.85r+35000
Subtract 0.85 from both sides
0.7r = 35000
divide by 0.7 on both sides
r = 50000
Profit function
P(x)= R(x)- C(x)
P(r) = 1.55r - (0.85r+35000)
P(r) = 1.55r - 0.85r - 35000
P(r) = 0.7r - 35000
State the equation that results when both sides of 2x - 3y = -4 are multiplied by -3.
Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation

A recipe calls for 2/3 of cups of milk for 11 cookies. How many cups of milk are needed to make 165 cookies?
Answer:
10 cups of milk
Step-by-step explanation:
Make a proportion, where x is the number of cups of milk for 165 cookies:
[tex]\frac{2/3}{11}[/tex] = [tex]\frac{x}{165}[/tex]
Cross multiply and solve for x:
11x = 110
x = 10
So, 10 cups of milk are needed to make 165 cookies

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form. (-6,6), (6,2)
Point-Slope form = y-y1=m(x-x1)
Y-6 = -1/3 (x+6)
Slope-intercept form = Y=mx+b
y = -1/3 + 4
The equation of line is y= -2/3x + 2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
Points: (-6,6), (6,2)
Slope= (-2 - 6)/( 6 -(-6))
slope= -8 / 12
slope= -2/3
Now, using slope intercept form
y-b = m(x- a)
y- 6 = -2/3( x + 6)
y -6 = -2/3x - 4
y= -2/3x + 2
Hence, the equation of line is y= -2/3x + 2.

Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Find one possibility for the number of nickels and number of dimes that could be in Priya's pocket. Write an equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. Explain what the point (13,6) means in this situation. Is the point (13,6) a solution to the equation you wrote? Explain your reasoning.
Answer:5x + 10y = 125
Step-by-step explanation
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent
Total value = $1.25
Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
