Answer:
Vicki takes 12 minutes.
Step-by-step explanation:
Call the time that Dennis takes to read; D
The time that Vicki takes to read is; V
As per the question;
Dennis takes 3 times as long as Vicki takes to read a paper, hence the equation formed is;
D = 3V
It is given that Dennis takes 36 minutes to read, hence
36 = 3V
Solve with inverse operations;
36 = 3V
/3 /3
12 = V

*sigh* help me *sigh again*
Answer:
3 and 6 and 24 top to bottom
Step-by-step explanation:
For the middle 18 divided by 6 is 3 so therefore you have to multiply 3 to 2 to get the answer for the first one. For the bottom one you have to do 8/2 and that equals 4 so you multiply 6 by 4 and 4 times 6 is 24, and the for the first one it’s pretty straight forward just divide the second column in half
A cab company charges a $4 boarding rate in addition to its meter which is $1.50 for every mile. Write a linear equation which models this. Use the equation to determine the total fare for a trip that is 2 miles, 3 miles and 5 miles.
Answer:
2 miles = 7$
3 miles = 8.50$
5 miles = 11.50$
Step-by-step explanation:
1.50$ per mile + 4$ boarding fee
2 miles
1.50 × 2 + 4 = 7
3 miles
1.50 × 3 + 4 = 8.50
5 miles
1.50 × 5 + 4 = 11.50
The linear equation of the question will be $4 + $1.50(x) where x is the number of miles.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
According to the data provided in the question,
The boarding charge of cab company = $4
Additional charge per mile = $1.50
So, the linear equation will be : ($4 + $1.50x)
Here, x represents the number of miles.
The fare for the trip of 2 mile : $4 + $1.50 (2) = 7
The fare for the trip of 3 mile : $4 + $1.50 (3) = 8.5
The fare for the trip of 5 mile : $4 + $1.50 (5) = 10

QUESTION 1 of 10: A Stadium sold 4,000 tickets at $75 ticket, 5,350 tickets at $62/ticket and 7,542 tickets at $49/ticket. What was the total
ticket sales revenue?
a
$16.392
Answer:
£1,001,258
Step-by-step explanation:
(75x4000)+(62x5350)+(49x7542)=£1,001,258
The total sales revenue of the tickets is required.
The total ticket sales revenue was [tex]\$1001258[/tex]
AlgebraNumber of $75 tickets sold = 4000
Number of $62 tickets sold = 5350
Number of $49 tickets sold = 7542
We multiply the number of tickets and the cost of tickets and add them.
[tex]4000\times 75+5350\times 62+7542\times49=\$1001258[/tex]

Find the principal of interest!! random answers will be reported
1. Interest: $640
Rate: 4%
Time: 1 year
2. Interest: $2,016
Rate: 12%
Time: 3 years
Answer:
4: $16,000
5: $4978.66
6: .086278 or 8.62%
Step-by-step explanation:
For the entirety of this problem I am going to assume that the interest is compounding annually
4: to find the interest earned in a period you have the following equation
(principle*(1+i)^n)-Principle
We can plug in the values we know
principle=p
(p*1.04)-p=640
This means that p=640/.04
p=16000
5: This is the same deal as the other one
2016=(p*(1.12)^3)-p
Solve this and get 1.404928p-p=2016
This means that .404928p=2016
Which means that p=4978.66
6: This one is slightly different but we can still use the same formula
720=4000((1+i)^2)-4000
We can add 4000 and then divide by 4000 to get
1.18=(1+i)^2
Take the square root of both sides and subtract 1 to solve for i
i= .086278 or 8.62%

Nellie took a total of 27 quizzes over the course of 3 weeks. After attending 4 weeks of school this quarter, how many quizzes will Nellie have taken in total?
Answer:
The answer is 36
Step-by-step explanation:
If you do 27÷3 you get 9. So if it's 4 weeks you just add 9 which is 36
Answer:
36
Step-by-step explanation:
First, we need to know how many quizzes she takes in 1 week.
27 /3 = 9
So, what is missing here is the number of quizzes is 4 weeks, so we will multiply 4 x 9.
4 x 9 = 36

Whose orange juice mixture tastes stronger? Explain or show your reasoning.
Answer: clare
Step-by-step explanation:
because you make denomenatior same i made mine 12
both can go to 12
hans mix would be: 8/12 water and 3/12 oranage
clare 6/12 water and 4/12 orange
hope you have a good day
Answer:
Han's Orange Juice
Step-by-step explanation:
Clare: 2 1/2 cups water and 1/3 cups concentrate
Han: 1 2/3 cups water and 1/4 cups concentrate
The way to solve this is to make one of the variables is by using the total:
Clare:
2 1/2 + 1/3 = 5/2 + 1/3 = 15/6 + 2/6 = 17/6 cup
(2/6)/(17/6) = (2/6)(6/17) = 2/17 (two parts in 17), or 11.8%
Han:
1 2/3 + 1/4 = 5/3 + 1/4 = 20/12 + 3/12 = 23/12 cup
(3/12)/(23/12) = (3/12)(12/23) = 3/23 (three parts in 23), or 13.04%
We can see Han's orange juice has more concentrate (the higher percentage).

Victor bought a handbag that was marked down 60% from an original price of $50. If he paid 15% sales tax, what was the total cost of the handbag
Answer:
$23
Step-by-step explanation:
first you find 60% of 50
50 x .6 = 30
then you subtract 30 from 50
30 - 50 = 20
since they paid $20 for the hand bag we need to find 15% of 20
20 x 0.15 = 3
finally we add 20 and 3
20 + 3 = 23
