Answer:
3. ASA (Angle Side Angle)
4. CPCTC (Congruent Parts of Congruent Triangles are Congruent)
Step-by-step explanation:
Since angle Q is congruent to angle T, side QR is congruent to side TR, and angle R is congruent to angle R, we can say that the triangles are congruent because of the Angle Side Angle Postulate.
With that being said, the other parts of the triangle are congruent, which is proved by the CPCTC theorem.

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee. Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee. After how many months are the costs for the girls’ cell phone plans the same?
Given:
Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.
Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.
To find:
The number of months after which the costs for the girls’ cell phone plans the same.
Solution:
Let x be the number of months.
Total cost = Fixed cost + Variable cost
According to the question, cost equation for Anna’s cell phone is
[tex]y=150+30x[/tex] ...(i)
Cost equation for Evelyn's cell phone is
[tex]y=450+20x[/tex] ...(ii)
Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.
[tex]150+30x=450+20x[/tex]
[tex]30x-20x=450-150[/tex]
[tex]10x=300[/tex]
Divide both sides by 10.
[tex]x=\dfrac{300}{10}[/tex]
[tex]x=30[/tex]
Therefore, the costs for the girls’ cell phone plans the same after 10 months.
Light bulbs cost £2.90 each.
Yasmin buys as many as she can with £20.
How much change should she get?
Answer:
$2.60
Step-by-step explanation:
first you need to see how many time 2.90 goes into 20 it is 6, so then you multiply 2.90 times 6 and get 17.40. Lastly you subtract 17.40 from 20 to get 2.60

1. Define y-intercept of a line?
2. In the slope intercept form: y=mx+b, what do the variables x, y, m, b stand for?
3. Define Slope of a line. Define Rise and Run. What are the four types of slope?
1. The y-intercept of a line is on a graph where a line crosses through the y axis.
2. b is the y- intercept and m is the slope. For example something using y=mx+b could be written like y=3x+2 if the y-intercept is 2 and the slope is 3.
3. The slope is what describes the direction and steepness of a line on a graph. Rise and run mean that when you find a slope you must first find the rise over run. You must go from one dot on a graph to the next by first going up or down to where that you are on the same number on the y axis that the next point is, next go on the x axis and go left or right until you have reached the next point. For example if you went up 3 and over 2, the rise would be 3 and the run would be 2. The slope in that situation would be 3/2.
Hope this helps you.

Answer:
Step-by-step explanation:
Given
A line has a slope = 2
point = (5,2)
Solution
y-y1=m (x-x1)
Where y1=2,X1=5,m=2
y-2=2(x-5)
Y-2=2x-10
2x-y=-8
Equation of the line is 2x-y=-8

Step-by-step explanation:
You operate a gaming website, www.mudbeast.net, where users must pay a small fee to log on. When you charged $4 the demand was 520 log-ons per month. When you lowered the price to $3.50, the demand increased to 780 log-ons per month.
(a) Construct a linear demand function for your website and hence obtain the monthly revenue R as a function of the log-on fee x.
R(x) =
(b) Your Internet provider charges you a monthly fee of $30 to maintain your site. Express your monthly profit Pas a function of the log-on fee x.
P(x) =
Determine the log-on fee you should charge to obtain the largest possible monthly profit.
x = $
What is the largest possible monthly profit?
$
Answer:
a)[tex]R(x)=-520x^2+2600x[/tex]
b)[tex]P(x)=-520x^2+2600x-30[/tex]
c)x=2.5
d)P(x)=3220
Step-by-step explanation:
Let Demand function be D=Ax+B
We are given that When you charged $4 the demand was 520 log-ons per month
So, D = 520 , x = 4
So, 520=4A+B ----1
We are also given that When you lowered the price to $3.50, the demand increased to 780 log-ons per month.
So, D=780 , x = 3.50
So, 780=3.5A+B ----2
Substract 2 form 1
4A+B-3.5A-B=520-780
0.5A=-260
[tex]A=\frac{-260}{0.5}[/tex]
A=-520
Substitute value of A in 2
780=3.5(-520)+B
780-3.5(-520)=B
2600=B
So, D=-520x+2600
Revenue = Demand (x)=(-520x+2600)(x)
a) [tex]R(x)=-520x^2+2600x[/tex]
b) Profit = Revenue - cost
[tex]P(x)=-520x^2+2600x-30[/tex]
c)to obtain the largest possible monthly profit.
Equate the first derivative of profit to 0
P'(x)=-1040x+2600=0
[tex]x=\frac{2600}{1040}[/tex]
x=2.5
d)Now to find the largest possible monthly profit
Substitute x = 2.5 in Profit function
[tex]P(x)=-520(2.5)^2+2600(2.5)-30[/tex]
P(x)=3220
6. Solve the problem. A carousel has a radius of 18 feet and takes 31
seconds to make one complete revolution. What is the linear speed of
the carousel at its outside edge? Express the answer in feet per second.
If necessary, round the answer to two decimal places.
Answer:
v = 3.64 ft/s
Step-by-step explanation:
Given that,
Radius of a carousel, r = 18 feet
It takes 31 seconds to complete revolution.
We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.
d = 2πr
d = 2π × 18 = 113.09 feet
Let v is the linear speed. It can be given by :
[tex]v=\dfrac{D}{t}\\\\v=\dfrac{113.09}{31}\\\\v=3.64\ ft/s[/tex]
So, the linear speed of the carousel is 3.64 ft/s.

Determine whether the graph represents a proportional relationship. (4 points) A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 15. Four points are shown on the graph on ordered pairs 0, 2 and 1, 6 and 2, 10 and 3, 12. These points are joined by a line. The label on the x-axis is Number of cars. The title on the y-axis is Number of wheels. Group of answer choices Yes, it is a proportional relationship because the graph goes through the origin Yes, it is a proportional relationship because the graph is a straight line No, it is not a proportional relationship because the graph is not a straight line No, it is not a proportional relationship because the graph does not go through the origin

The table shows the prices of some candy items at a store. Jake selected 1.6 pounds of Fruit Chews and 2.6 pounds of Jelly Beans. The sales tax for his purchase was $0.52.
.Item. .Price Per Pound.
.Fruit Chews. - $4.70
.Jelly Beans. - $2.35
.Chocolate. - $3.50
.If Jake had $25 to spend at the candy store, how much money did Jake have left after his purchase?
Answer : 11.80$
Step-by-step explanation:
He spends 8.70$ on Fruit chews and..
4.50 $ on jelly beans
add them up then subtract them by the amount of money he already has
BRAINLIST ???
Answer:
He had 10.85 left
Step-by-step explanation:
Fruit chews 4.7 x 1.6 = 7.52
Jelly beans 2.35 x 2.6 = 6.11
7.52 + 6.11 + 0.52 = 14.15
25 - 14.15 = 10.85

Answer:
CV of Bank A = 6.4
CV of Bank B = 7.1
CV of Bank B is more than CV of Bank A
Step-by-step explanation:
Bank A

Happy Paws charges $19.00 plus $4.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $5.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the varlable h to represent the number of hours.
Answer: its 20.5 i think i hope its right
Step-by-step explanation:
Answer: The equation is: 11+5.75h=19+4.5h The total cost of the services will be equal at 6.4 hours
Step-by-step explanation:
11 + 5.75h = 19 + 4.5h
-11 from both sides
5.75h = 8 + 4.5h
-4.5h from both sides
1.25h = 8
8 / 1.25 = 6.4,
Therefore, h=6.4
