Answer:
Abraham
Step-by-step explanation:
Abraham used the correct equation because if we represent the original size as 100% and decrease that by 20 it would be 80% or 0.8
Nasser's equation will solve for the change in price
Kathleen's equation solves for if the popcorn size was increased by 20%
Answer:
nasser
Step-by-step explanation:
0.20 = 20/100=20%
What is 0.0492 in standard form?
Answer: How to write numbers in standard form:
Write the first number 8.
Add a decimal point after it: 8.
Now count the number of digits after 8. There are 13 digits.
So, in standard form: 81 900 000 000 000 is 8.19 × 10¹³

...........
Step-by-step explanation:
-2x² + 5x - 3 - (-7 - 9x + 5x²)
= -2x² + 5x - 3 + 7 + 9x - 5x²
= -7x² + 14x + 4.
Hence the coefficient of the x term is 14.

Step-by-step explanation:
The two given equations have slope -1/2 and 2 and are perpendicular lines.
The lines on the graph are different from the equations at left.
Their slopes are 2 and 1/2. Since they are not opposite reciprocals, they are not perpendicular.

2. Lorena is trying to choose between two different savings accounts at H-Town Bank. She will deposit $3,500 dollars and will leave the money in the account for 12 years. There will be no additional money deposited or withdrawn from the account.
Answer:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Choice 1 = X = Final Amount after 12 years = $5600
Choice 2 = Y = Final Amount after 12 years = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.
Step-by-step explanation:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Initial Deposit Amount = $3500
Time period = 12 years
Let's Suppose Lorena has two X and Y choices of accounts at H-town Bank.
X = simple interest of 5% over the initial amount for 12 years.
Y = Compound interest 5% over the initial amount for 12 years.
Solution:
Let's calculate the profit for choice 1 = X
Simple interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P (1 + rt)
where, A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
Plug in the values to get the total amount.
A = 3500(1+0.05x12)
A = $5600 = final amount Lorena will get after 12 years.
Let's calculate the profit for choice 2 = Y
Compound interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
where,
A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
n = number of times interest rate is applied or compounded. = 12
Plug in the values to get the total amount.
A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
A = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.

how many solutions does the system of equations have?(1 point)
3x=-12y+15 and x+4y=5
A-one
B-two
C-infinitely many
D-none
Answer:
c
Step-by-step explanation:
First, I'll isolate the x in x+4y=5 to match with the other equation.
The new equation would be x= -4y+5
Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.
-1(-12y + 15 = 3x )
3(-4y + 5 = x)
The new equations would be :
12y - 15 = -3x
-12y + 15 = 3x
Add the equations and you get
0 = 0
The equation has an infinite amount of solutions

Sonya made a graph showing the first ten minutes of her drive to the movies.
A graph with time on the x-axis and speed on the y-axis. The graph increases, increases rapidly, and then remains constant.
Which description is the best interpretation of the graph?
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
Sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. She stopped the car.
Sonya drove down her driveway at a constant speed until she reached the street. She turned and drove down the street at a constant speed. Her car went slower as she drove up a hill. At the top of the hill she drove into the parking lot of the movie theater.
Sonya accelerated as she drove down her driveway. She accelerated on the street on her way to the highway entrance. She waited for a red light, then accelerated onto the highway.
Answer:
A
Step-by-step explanation:
A. because the first point shows her acceleration and you can see her speed increasing when she hits the second point, so we can say that see accelerated up the ramp and after it hits the third point her speed becomes constant all the way when she reached the highway

Answer:
x > 1
Step-by-step explanation:
15 - 1 = 14
The inequality is 15 - 1 < 14, but this is incorrect. 14 can not be less than 14. In order for the left side to be less than 14, the x value (currently representing 1) should be larger than what it currently is to make the statement true.
Therefore, x>1

Given: 5x + 3 > 4x + 7.
Choose the graph of the solution set.
[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]
Step-by-step explanation:For the number line refer to the attachment :
A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-
[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]
This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .
Hence the first graph of the solution set represents the given linear inequality.Answer: B is correct
Step-by-step explanation: Tried a on the test, got it wrong, then tried b and got it right.
Oak Street and Elm Street run parallel to each other. When Main Street
intersects them, it forms interior 26, measuring 70°. What is the measure of
24?
Answer:
110°
Step-by-step explanation:
The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).
Therefore:
∠4 and ∠6 are consecutive interior angles. Hence:
∠4 + ∠6 = 180° (sum of co-interior angles)
∠4 + 70 = 180
∠4 = 180 - 70
∠4 = 110°
Answer:
110°

Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0 whitch function represents the amount in Olivias savings account after x weeks
Answer:
y = 127 + 5x
Step-by-step explanation:
Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0
Let x = number of weeks Olivia deposits money.
y = Total pint of money that Olivia has in her account after x weeks
Hence, the function represents the amount in Olivias savings account after x weeks is ;
y = $127 + $5 × x
x < 0
y = 127 + 5x

Maria is planning a party for her friends. Sally's Kitchen charges a fee of
$60 to set up and then $12 per plate. Jimmy's BBQ and Steak charges a fee
of $100 to set up and then $10 per plate. At how many plates will the cost
of Sally's and Jimmy's be the same? How many plates will the cost of
Sally's and Jimmy's be the same? *
Answer:
20 Plates
Step-by-step explanation:
Given that :
Sally's kitchen :
Setup cost = $60
Cost per plate = $12
Jimmy's BBQ :
Setup cost = $100
Cost per plate = $10
Let number of plates = x
Equate both and solve for x :
Sally's kitchen = Jimmy's BBQ
60 + 12x = 100 + 10x
12x - 10x = 100 - 60
2x = 40
x = 40/2
x = 20
20 plates
