Answer:
Chase and his brother will both have a score of 31 points by making 4 successful shots.
Step-by-step explanation:
Given that initially Chase has 19 points and his brother has 27 points.
In one successful flip, Chase get 3 points and in one successful flip, his little brother get 3 points
Assuming that both have the same score after n number successful flip of the coin.
So, points earned by Chase in n successful flip [tex]= 3\times n =3n[/tex]
and points earned by his little brother in n successful flip [tex]= 1\times n=n[/tex].
Total points of Chase [tex]= 19+3n\cdots(i)[/tex]
Total points of his little brother [tex]= 27 + n\cdots(ii)[/tex]
As the brothers have tied scores in the game, that means both have the same score, so from equations (i) and (ii), we have
[tex]19+3n = 27 + n \\\\\Rightarrow 3n-n = 27-19 \\\\\Rightarrow 2n=8 \\\\\Rightarrow n=8/2=4[/tex]
So, after n successful throw, both have the same score.
Hence, each brother made 4 additional successful shots.
Now, put n=4 inequation (i) or (ii) to get the total points, i.e
Total points of each brother [tex]= 19+ 3\times 4 = 31.[/tex]
Hence, each brother has 31 points.

Jenna works in an ice cream shop. When she starts her shift the tub of chocolate ice cream is 2/3 full. When she finishes her shift 6 1/2 h later,
there is only 1/6 of the tub left. What was the average hourly change in tub fullness?

Answer:
1/13
Step-by-step explanation:
Ice cream
starting = 2/3 full
After Jenna's shift = 1/6 of the tub
Total Time = 6.5hours
Amount of ice cream consumed = [tex]\frac{2}{3} - \frac{1}{6}[/tex]
= [tex]\frac{1}{2}[/tex] = 0.5
Rate per hour = amount of ice cream consumed -=/ total time
= 0.5/6.5 = 1/13 ice cream consumed per hour

The slash is the fraction bar jsyn :)) pls help
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]p - \frac{19}{6} = - \frac{15}{6} \\ [/tex]
Add sides 19 / 6
[tex]p - \frac{19}{6} + \frac{19}{6} = - \frac{15}{6} + \frac{19}{6} \\ [/tex]
[tex]p = \frac{19 - 15}{6} \\ [/tex]
[tex]p = \frac{4}{6} \\ [/tex]
[tex]p = \frac{2 \times 2}{2 \times 3} \\ [/tex]
[tex]p = \frac{2}{3} \\ [/tex]

Angela is riding a scooter around her neighborhood. The front wheel has a diameter of 10 inches and the back wheel has a diameter of 5 inches. The scooter is moving at a speed of 10 inches per second.
As she is riding her scooter, a spider hops onto the front wheel. Angela looks down and thinks that if the praying mantis has a good grip that he will go all the way around the wheel in just 1 second. Is Angela right or wrong? Why?
If she is wrong find the amount of time it will take to go all the way around
Answer:
i. Angela is wrong. Because the diameter of the wheel is not the distance covered all the way round.
ii. The time is 3.14 seconds.
Step-by-step explanation:
The font wheel has a diameter of 10 inches. Thus;
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{10}{2}[/tex]
= 5 inches
Circumference of a circle = 2[tex]\pi[/tex]r
⇒ The circumference of the front wheel = 2[tex]\pi[/tex]r
= 2 x [tex]\frac{22}{7}[/tex] x 5
= 31.4286
The circumference of the front wheel is 31.43 inches.
The total distance to be covered by the mantis = circumference of the front wheel
= 31.43 inches
But,
speed = [tex]\frac{distance}{time}[/tex]
The scooter moves with a speed of 10 inches per second, so that;
10 = [tex]\frac{31.43}{time}[/tex]
⇒ time = [tex]\frac{31.43}{10}[/tex]
= 3.143 s
The time taken to complete a revolution by the mantis is 3.14 seconds.
Therefore,
i. Angela is wrong. Because the diameter of the wheel is not the distance covered all the way round.
ii. The time is 3.14 seconds.

Step 1: Define
P(x) = x³ + 4x² - 3x + 1
P(1) is x = 1
P(-2) is x = -2
Step 2: Evaluate
P(1)
Substitute: P(1) = 1³ + 4(1)² - 3(1) + 1Exponents: P(1) = 1 + 4(1) - 3(1) + 1Multiply: P(1) = 1 + 4 - 3 + 1Add: P(1) = 5 - 3 + 1Subtract: P(1) = 2 + 1Add: P(1) = 3P(-2)
Substitute: P(-2) = (-2)³ + 4(-2)² - 3(-2) + 1Exponents: P(-2) = -8 + 4(4) - 3(-2) + 1Multiply: P(-2) = -8 + 16 + 6 + 1Add: P(-2) = 8 + 6 + 1Add: P(-2) = 14 + 1Add: P(-2) = 15Answer:

1. What is the solution of the system of equations shown below?
y = 3x + 7
y = x-9
Answer:
x= -8
y= -17
Step-by-step explanation:
Answer:
If you trying to find x and y is the answer is:
x=-8 and y=-17
or
(-8,-17)
Step-by-step explanation:
First you need to subtract the two equations which becomes 2x+16=0
Now you move the 16 to the other side by subtracting 16 on both sides:
2x=-16
Now divide 2 on both sides to eliminate the 2 on 2x
x=-8
Now that you got -8 as x you can replace x on the two equations any one of them you only need to get one but I am going to use both of them to show you that it is the same:
y= 3(-8)+7
y=-17
y=-8-9
y=-17
Hope this helps!
Hanna is plotting a point in coordinate space. She starts at the origin and moves backward eight units along the x-axis. Then she moves right one unit parallel to the y-axis. Finally, she moves down five units parallel to the z-axis and plots the point. What are the coordinates of the point that she plots?
Answer:
( -8,0, 0) , ( -8, 1, 0) and ( -8, 1, -5)
Step-by-step explanation:
We need to visualize the given situation in 3D
Coordinates is in the form of (x, y, z)
Henna starts from origin moves back 8 units Negative x-axis
x = -8 point will be ( -8,0, 0)
turning 1 unit right will be parallel to the y axis in positive y-axis direction
y = 1 point will be ( -8, 1, 0)
Moving down by 5 units, Negative z-axis
Z = -5 point will be ( -8, 1, -5)
Answer:
(-8,1,-5)

what are the solutions to the quadratic equation 6x^2 + 24X = 0?
Answer: {0, -4}
Step-by-step explanation: Notice that the two terms on the left side
of the equation have a greatest common factor of 6x.
So start by factoring out a 6x to get 6x(x + 4) = 0.
So either 6x = 0 or x + 4 = 0.
Eventually we find that x = 0 or x = -4.
So our solution set is {0, -4}.

Answer:
7) nth term a₁₈ is 160
8) nth term a₃₆ is 128
Step-by-step explanation:
7) Find nth term of each arithmetic sequence
[tex]a_1=7, d=9, n=18[/tex]
The formula used to find nth term is: [tex]a_n=a_1+(n-1)d[/tex]
Putting values and finding nth term n=18
[tex]a_n=a_1+(n-1)d\\a_{18}=7+(18-1)9\\a_{18}=7+(17)9\\a_{18}=7+153\\a_{18}=160[/tex]
So, nth term n₁₈ is 160
8) Find nth term of each arithmetic sequence
[tex]a_1=-12, d=4, n=36[/tex]
The formula used to find nth term is: [tex]a_n=a_1+(n-1)d[/tex]
Putting values and finding nth term n=36
[tex]a_n=a_1+(n-1)d\\a_{36}=-12+(36-1)4\\a_{36}=-12+(35)4\\a_{36}=-12+140\\a_{36}=128[/tex]
So, nth term n₃₆ is 128

Which of the following correctly demonstrates a verb tense shift? a. Kurtis is moving to a new city to start the job he was hired for. b. Kurtis moved to a new city and is started the new job he was hired for. c. Kurtis moved to a new city to starting the job he was hired for. d. Kurtis will be moving to a new city to started the job he was hired for. D is wrong
Answer: a. Kurtis is moving to a new city to start the job he was hired for.
Step-by-step explanation: "is moving" is present progressive tense.
"was hired" is passive past tense.
"to start" is an infinitive.
These are correct verb forms.
b is almost correct. Kurtis "moved" is OK in the past tense. *is started* should be "has started"
c is partly correct. *to starting* is ungrammatical here.
d is wrong because *to started* is always ungrammatical.
