3. Susan invested $10,000 in an account that earned 3% interest, compounded monthly.
a. Write an exponential growth/decay formula to model the situation.
b. What is the value of this account after 5 years? Express your answer rounded to the nearest cent.
A) total = 10,000 *(1+0.03/12)^(12*t)
B) t = 5 years
10,000 *(1+0.03/12)^(12*5 ) = $11,616.17
The value of Susan's account after 5 years, compounding monthly with a 3% interest rate, is approximately $11,593.74.
To model the situation, we can use the formula for Compound Interest: A = P(1+r/n)^(nt), where A is the amount after time t, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per time period, and t is the time in years.
In this case, P = $10,000, r = 3% or 0.03, n = 12 (compounded monthly), and t = 5.
Substituting these values into the formula, we get:
A = $10,000(1+0.03/12)^(12*5)
Calculating this expression gives us an amount of approximately $11,593.74 after 5 years.
Rounded to the nearest cent, the value of the account is $11,593.74.

Bethany is baking cookies for her school's bake sale. She plans to bake more than 185 cookies, in batches of 12 cookies. So far, Bethany has baked a total of 48 cookies. What inequality describes this situation, if b represents the number of batches of cookies Bethany has left to bake?
The inequality that describes this situation is "b > 12", where b represents the number of batches of cookies Bethany has left to bake.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the question, we can start by subtracting the number of cookies that Bethany has already baked (48) from the total number of cookies she plans to bake (185).
This gives us a difference of 185 - 48 = 137 cookies.
Dividing this number by the number of cookies per batch, we get 137 / 12 = 11.41.
Since Bethany is baking whole batches of cookies, the number of batches she has left to bake must be at least 12.
This means b > 12
Therefore, the inequality "b > 12" accurately describes the situation, where b is the number of batches Bethany has left to bake.

opposite angle equal each other so you have:
6x+34 = 8x +14
subtract 14 from each side:
6x+20 = 8x
subtract 6x from each side
20 =2x
divide both sides by 2
x = 20/2
x = 10

On a circle graph, a section with an angle measuring 180 represents A:18%, B:50%, C:90% of the whole.
Consider the two functions which statement is true
The slope of the line in the graph is 1/2, and for the table the slope is 2.
Which is true about the two functions?We can se two linear functions, remember that if a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of the line is given by the formula:
a = (y₂ - y₁)/(x₂ - x₁)
For the first line we can see it passes through (-4, 0) and (0, 2), then the slope is.
a = (2 - 0)/(0 + 4) = 1/2
For line b we can use the first two pairs in the table (2, 3) and (3, 5)
So the slope is:
a = (5 - 3)/(3 - 2) = 2
These are the slopes of the lines.

7 berries are 5 less than twice the number of berries Mickey had for lunch.
The subject of this question is Mathematics.
Explanation:To define the subject of the question, we can see that it involves a mathematical problem. The question asks about the relationship between the number of berries a student has and the number of berries Mickey had for lunch. Therefore, the subject of this question is Mathematics.
7 berries are 5 less than twice the number of berries Mickey had for lunch can be represented as 7 = 2m - 5. Therefore, the correct option is c.
The problem states: "7 berries are 5 less than twice the number of berries Mickey had for lunch."
Let's represent the number of berries Mickey had for lunch as 'm'.
Now, translate the problem into an equation based on the information given:
"7 berries are 5 less than twice the number of berries Mickey had for lunch."
Twice the number of berries Mickey had for lunch is 2 times 'm', which is 2m.
"5 less than twice the number of berries Mickey had for lunch" means subtracting 5 from twice the number, so it's 2m - 5.
And finally, the equation becomes:
7 = 2m - 5
So, the correct representation of the situation in an equation is option C: [tex]$7 = 2m - 5$[/tex].
The complete question is given below:
7 berries are 5 less than twice the number of berries Mickey had for lunch. Choose the correct linear equation.
A. [tex]$7=5-2 m$[/tex]
C. [tex]$7=2 m-5$[/tex]
B. [tex]$5=2 m-7$[/tex]
D. [tex]$12=\frac{m}{2}$[/tex]
a piece of yellow yarn was 230 inches long. After 90 inches had een cut from it,,, the piece of yellow yarn was twice as longas a piece of blue yarn. How much longer than the blue yarn was the yellow yarn at first?
Answer:
160 inches longer.
Step-by-step explanation:
Let x represent the length of the blue yarn.
We have been given that a piece of yellow yarn was 230 inches long. After 90 inches had been cut from it, the piece of yellow yarn was twice as long as a piece of blue yarn.
Twice the length of blue yarn would be [tex]2x[/tex].
We can represent this information in an equation as:
[tex]2x+90=230[/tex]
[tex]2x+90-90=230-90[/tex]
[tex]2x=140[/tex]
[tex]\frac{2x}{2}=\frac{140}{2}[/tex]
[tex]x=70[/tex]
Therefore, the length of blue yarn is 70 inches long.
Now, we will subtract 70 from 230 as:
[tex]230-70=160[/tex]
Therefore, the yellow yarn was 160 inches longer than the blue yarn.
