Answer:
The $3485.52 money did Meg have at the end of the account term.
Step-by-step explanation:
Formula for compounded monthly
[tex]Amount = P(1+\frac{r}{365})^{365n}[/tex]
Where P is the principle , r is the rate of interest in the decimal form and n is the number of years.
As given
Meg deposited a $3,000 bonus check in a new savings account. The account has an interest rate of 3% for 5 years.
Principle = $3000
3% is written in the decimal form
[tex]= \frac{3}{100}[/tex]
= 0.03
Time = 5 years
Put in the formula
[tex]Amount = 3000(1+\frac{0.03}{365})^{365\times 5}[/tex]
[tex]Amount = 3000(1+\frac{0.03}{365})^{1825}[/tex]
[tex]Amount = 3000(1+\frac{0.03}{365})^{1825}[/tex]
[tex]Amount = 3000(1+ 0.0000822)^{1825}[/tex]
[tex]Amount = 3000(1.0000822)^{1825}[/tex]
[tex]Amount = 3000\times 1.16184[/tex]
Amount = $ 3485.52
Therefore the $ 3485.52 money did Meg have at the end of the account term.

Ratio represents partial data as some multiplies from numerator and denominator are lost due to simplification. You can assume them to be variables.
The ratio of dogs to cats is 3:5
How to get real quantity of ratio of first quantity to second quantity = a:b?We actually cannot get real quantities but we can use variables to partially get the information of how much their quantities were.
I said 'partially' since we don't get real values but with variables only.
Since the ratio is a:b, thus let the cancelled multiple during simplification was x.
Then we have:
First quantity = ax
Second quantity = bx
How to calculate the ratio of dogs to cats?It is given that:
Ratio of dogs to fish = 1:10
Then let number of dogs = 1x = x and number of fishes = 10x
Similarly,
Ratio of fish to cats = 6:1
Then let the multiple was y, then
Number of fishes = 6y,
Number of cats = 1y = y
But we have number of fishes = 10x and 6y both
Since number of fishes is constant, thus, they are equal. Or
[tex]10x = 6y\\\dfrac{x}{y} = \dfrac{6}{10} = \dfrac{3}{5}\\[/tex]
The ratio of dogs to cats = [tex]\dfrac{\text{Numbers of dogs}}{\text{Number of cats}} = \dfrac{x}{y} = \dfrac{3}{5}[/tex]
Thus, the ratio of dogs to cats is 3:5

after 8% discount from the list price, the sale price price of a poster was $17.48. what was the list price of poster.
Final answer:
To find the list price of the poster after an 8% discount, subtract 8% of the list price from the list price and set it equal to the sale price.
Explanation:
To find the list price of the poster, we need to first calculate the original price before the discount. Let's assume the list price is 'x' dollars. After an 8% discount, the sale price of the poster is $17.48.
We can set up an equation to solve for the list price: x - 8% of x = $17.48. To calculate 8% of x, we multiply x by 0.08.
So the equation becomes: x - 0.08x = $17.48. Combining like terms, we get 0.92x = $17.48. Dividing both sides by 0.92, we find that x = $19.

A line has a slope of -1/2 and a y-intercept of –2.
What is the x-intercept of the line?
a.–4
b.–1
c.1
d.4
Answer:
a.-4
Step-by-step explanation:
I pictured it as a graph and since the slope is negative, the line goes down and to the right. Since the slope is -1/2, for every 2 you move horizontally, you move one vertically. You have to move two up and unless the y intercept is 0, when the line intercepts y, you have 0 as x. You move two up and 4 backwards so the x intercept is -4

The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points E(2, 2), C(0, 3) and G(4, 1), C(0, 3).
Substitute:
[tex]\dfrac{3-2}{0-2}=\dfrac{3-1}{0-4}\to\boxed{D}[/tex]
Answer: The correct option is (D) [tex]\dfrac{3-2}{0-2}=\dfrac{3-1}{0-4}.[/tex]
Step-by-step explanation: Given that ΔCDE and ΔCFG are similar right triangles.
We are to select the correct proportion that can be used to show that the slope of CE is equal to the slope of CG.
We know that the slope of a line passing through two points (a, b) and (c, d) is given by
[tex]m=\dfrac{d-b}{c-a}.[/tex]
From the given figure, we note that the co-ordinates of the points C, E and G are
C(0, 3), E(2, 2) and G(4, 1).
So, the slope of line CE is given by
[tex]m_1=\dfrac{2-3}{2-0},[/tex]
and the slope of line CG is given by
[tex]m_2=\dfrac{1-3}{4-0}.[/tex]
Since the lines CE and CG are same, they must be parallel and hence they have equal slopes.
Therefore,
[tex]m_1=m_2\\\\\\\Rightarrow\dfrac{2-3}{2-0}=\dfrac{1-3}{4-0}\\\\\\\Rightarrow \dfrac{3-2}{0-2}=\dfrac{3-1}{0-4}.[/tex]
Thus, (D) is the correct option.

Addison plays 1/2 of a song in 1/4 of a minute. How minutes will she need to play a full song?
Answer:
30 minutes
Step-by-step explanation:
She plays 1/2 of a song in 1/4 of a minute so that would be 15 minutes because if you divide 60 by 4 you would get 15. You would multiply 15 by 2 because if she plays a full song you multiply 1/2 by 2 to get a whole. So she will need 30 minutes to play a full song
I spent 3/4 of my money and then I spent 1/5 of what was left.
a) What part of all my money did I spend?
b) What part of all my money do I have left?
Answers:
a) 4/5
b) 1/5
================================================
Let's say you start off with $100. If you spend 3/4 of that, then you spend 75 dollars (because 75/100 = 3/4). Think of it like 75 cents = 3 quarters. If you spend 75 dollars out of 100 total, then you have 100-75 = 25 dollars left after the first round of spending.
If you spend 1/5th of what is left, then you spend $5 on the second round leaving 25-5 = 20 dollars left at the end of the day.
Total up what you spend for both rounds: 75+5 = 80, which divides over the original amount 100 to get 80/100 = 8/10 = 4/5
If you had 20 dollars at he end of the day, out of 100 initially, then 20/100 = 2/10 = 1/5 is the fraction of what you have left.
note how 4/5 and 1/5 add to 5/5 = 1.00 = 100%. This is because the amount you spend and the amount you have left over must add to 100% of all the money you started with

Answer:
y+9 =-5(x-2) point slope form
y = -5x-1 slope intercept form
Step-by-step explanation:
If we have a slope and a point, we can use the point slope form of a line
y-y1 = m(x-x1)
y--9 = -5(x-2)
y+9 =-5(x-2)
If you want to write it in slope intercept form, distribute the -5
y+9 = -5x+10
Subtract 9 from each side
y+9-9 = -5x+10-9
y = -5x-1
How do i graph the equation -x + 2y = 2
Step-by-step explanation:
Firstly, set the x value as 0:
-0 + 2y = 2
2y = 2
y = 1
So when x = 0, y = 1
Now set y to 0:
-x + 2(0) = 2
-x = 2
x = -2
So when y = 0, x = -2

Deena decides to mark down prices at her jewelry store 20% for a clearance sale. She must add 6% to the sale price for state sales tax. Suppose an item was originally priced at x dollars. Which expression does not represent the total sale price, including sales tax, of the item?
The expression that does not represent the total sale price, including sales tax, of the item is x * (1 - 0.20 + 0.06). Hence the correct option is c.
1. Calculate the sale price after the markdown:
Original price: x dollars
Markdown rate: 20%
Sale price after markdown: x * (1 - 0.20) = 0.8x dollars
2. Calculate the amount of sales tax:
Sales tax rate: 6%
Sales tax amount: 0.06 * 0.8x = 0.048x dollars
3. Calculate the correct total sale price:
Sale price after markdown + Sales tax amount = 0.8x + 0.048x = 0.848x dollars
4. Analyze the given expressions:
x * (1 - 0.20) + 0.06x: This expression correctly calculates the discount and adds the sales tax to the original price, so it represents the total sale price.
x * (1 - 0.20) + 0.06 * 0.8x: This expression also correctly calculates the discount and adds the sales tax to the discounted price, so it represents the total sale price.
x * (1 - 0.20 + 0.06): This expression combines the discount and sales tax into a single percentage (14%), but it applies this percentage to the original price (x) instead of the discounted price (0.8x). This leads to an overestimation of the final sale price, so it does not represent the correct total price.
0.8x + 0.048x: This expression correctly calculates the sum of the discounted price and the sales tax amount, so it represents the total sale price.
Therefore, the expression that does not represent the total sale price, including sales tax, of the item is x * (1 - 0.20 + 0.06). Hence the correct option is c.

The point (2,-2) and (-4,13) on the graph of a linear function of x. Which point also lies on the graph of this function?
A. (-6,18)
B. (-1,5)
C. (7,14.5)
D. (13, -4)
Answer:
A. (-6,18)
Step-by-step explanation:
The point (2,-2) and (-4,13) on the graph
First we frame an equation of the line using two points
y = mx + b where m is the slope and b is y intercept
slope = [tex]\frac{y_2-y_2}{x_2-x_1} =\frac{13+2}{-4-2} = \frac{15}{-6} = -2.5[/tex]
m = -2.5
Lets find out b
y = mx+b
y= -2.5x + b
Plug in (2,-2) and find out b
-2 = -2.5(2) + b
-2 = -5 + b (add 5 on both sides)
b = 3
so equation of line is y = -2.5 x + 3
Now we check with each option
(-6,18)
Plug in the x and y in our equation and check it
y = -2.5 x + 3
18 = -2.5(-6) + 3
18 = 15+3
18=18 true
So (-6,18) lies on the graph

The compass must be flexible and at the same time it must be able to stay at one radius unless changed by the owner. It's only property is that it can draw a perfect circle once the radius of the circle has been chosen,
The U.S. produces about 5.5 million tons of apples each year. Of the total, $20\%$ is mixed with other products, with $50\%$ of the remainder used for apple juice and the other $50\%$ sold fresh. How many million tons of apples are used for apple juice? Express your answer as a decimal to the nearest tenth.
Answer:
2.2 million tons
Step-by-step explanation:
20% of 5.5 million tons is 1.1 million tons. That is how many are mixed with other products. So that would leave you 4.4 million tons of apples.
50% of 4.4 is 2.2 so 2.2 million tons are used for apple juice.
Answer:
2.2 Million
Step-by-step explanation:
First, we wish to determine what percentage of the tons of apples are used for apple juice. After 20% is mixed with other products, 80% remains. Half of this is used for apple juice; therefore, 40% of the tons of apples is used for apple juice. To calculate 40% of 5.5 million tons, we find 10% and then multiply by four. 10% = 0.55, and 0.55* 4 = 2.2. Thus, 2.2 million tons are used for apple juice.
Year 1 number sold 725
Year 2 number sold 579
Year 3 number sold in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number of scooter sold in year 4
Answer:
2, 240
Step-by-step explanation:
In the table, the values should be
Year 1 725
Year 2 579
Year 3 696
Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.
[tex]\frac{112}{100} =\frac{x}{2000}[/tex]
We solve through cross multiplication of numerator and denominator of the opposite fraction.
[tex]112(2000)=100(x)\\224000=100x\\2,240=x[/tex]
