Answer:
18 ferrets
Step-by-step explanation:
From the statement you can write the following:
c+r+f= 108
c=cats
r= rabbits
f= ferrets
Then, you have that one third of the animals are cats:
c= 108*(1/3)= 36
Next, three fourths of the remaining animals are rabbits:
r= (108-36)*(3/4)= 72*(3/4)= 54
Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:
f=108-c-r
f=108-36-54
f= 18
According to this, the answer is that there are 18 ferrets.

Answer:
9 /16 cups
Step-by-step explanation:
Take the number of cups and divide by the number of servings
2 1/4 ÷ 4
Change to an improper fraction
9/4 ÷4
Copy dot flip
9/4 * 1/4
9 /16
Answer: 9/16
Step-by-step explanation: First, take the number of cups and divide by the number of servings. So we have 2 and 1/4 ÷ 4.
Now, rewrite 2 and 1/4 as the improper fraction 9/4 an 4 as 4/1.
So we have 9/4 ÷ 4/1.
Now, dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division sign to multiplication and flip the second fraction. So 9/4 ÷ 4/1 can be rewritten as 9/4 × 1/4.
Now, multiply across the numerators and denominators to get 9/16.
So there are 9/16 cup of raisins in each serving.
The graph of y = f '(x), the derivative of f(x), is shown below. Given f(-4) = 2, evaluate f(4).
The options are:
0
2
8
10
Answer:
2
Step-by-step explanation:
f'(x) is an odd function (symmetrical about the origin), therefore f(x) is an even function (symmetrical about the y-axis). So f(x) = f(-x).
Since f(-4) = 2, f(4) = 2.
We can also show this using integrals:
f(-4) = ∫₀⁻⁴ f'(x) dx + C
2 = ½ (-4)(-2) + C
2 = 4 + C
C = -2
f(4) = ∫₀⁻⁴ f'(x) dx − 2
f(4) = ½ (4)(2) − 2
f(4) = 4 − 2
f(4) = 2
Cost to store: $75
Percent of Markup:
Selling price: $112.50
Answer:
15%
Step-by-step explanation:
pretty sure thats right
Final answer:
The student's question involves a business math concept of calculating the percent markup from the cost and selling price, resulting in a 50% markup for this example.
Explanation:
The question involves calculating the percent markup based on the cost to store an item and its selling price.
To find the percent of markup, you subtract the cost to store from the selling price and then divide by the cost to store.
Finally, multiply by 100 to get the percentage.
For example, if an item costs $75 to store and sells for $112.50, the markup is ($112.50 - $75) / $75 = 0.50, or 50%.
This is an example of a basic markup calculation commonly covered in business and economics classes in high school.

Amanda has a ribbon that is 6 feet long. She wants to cut it into 12 equal pieces. How long will each piece be? Write the steps, in order, you would take to solve the problem. * 2 points Your answer
Answer:
Each of the pieces will be 0.5 feet long
Step-by-step explanation:
In this question, we are asked to calculate the individual length Anita will cut a ribbon 6 feet long into to ensure that each of the piece has the same length.
To calculate this, since we don not know what length each of the piece would be, we can say let the length of each of the pieces be x feet
Now, we know that there are 12 pieces that are equal in length. The length of all these 12 pieces would be 12 * x = 12x feet
Now what do we know again?
We also know that these 12x feet equals a total of 6 feet
mathematically therefore;
12x = 6
x = 6/12
x = 0.5 feet
Answer: Each piece will be 1/2 feet long.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given.
We simply have to divide the length of the ribbon (6) by the number of pieces that she wants to cut (12).
Mathematically speaking:
6 /12 = 1/2
In conclusion, each piece will be 1/2 feet long.

David picks a card at random.
Without putting the first card back, he picks a second card at random.
Are these two events dependent or independent?
Answer:
dependent
Step-by-step explanation:
This question assumes that we're working with a standard full deck of cards. There are 52 unique cards in such a deck.
If David picks a card at random and doesn't put it back, then the number of unique cards left in his deck is 51.
These two events are dependent because the withdrawal of 1 card changes the probability of drawing any other of these 51 cards

solve each system by elimination 3x-y=-2 -2x+y=2
The solution to the system of equations is (x, y) = (0, 2).
To solve the system of equations using the elimination method, we'll eliminate one of the variables by adding or subtracting the equations. Let's proceed:
Given the system of equations:
3x - y = -2
-2x + y = 2
We'll add the two equations together to eliminate the variable y:
(3x - y) + (-2x + y) = (-2) + 2
This simplifies to:
3x - y - 2x + y = 0
x = 0
Now, substitute x = 0 into one of the original equations to solve for y. Let's use the first equation:
3(0) - y = -2
-y = -2
y = 2
So, the solution to the system of equations is (x, y) = (0, 2).
Your friend is investing in a 401(k) that promises 2% annual growth. He plans on investing $250 each month for 25 years. Excel returns a value of $97,205.28 for the balance in the 401(k) after 25 years. How much interest is earned in the account after 30 years?
Final answer:
After 30 years of monthly $250 contributions to a 401(k) with a 2% annual growth rate, the interest earned on the account is approximately $65,961.73.
Explanation:
To calculate the amount of interest earned in the 401(k) after 30 years with a 2% annual growth rate, we first need to figure out the future value of the account. We use the formula for the future value of an annuity, as the investments are made at regular intervals (monthly).
The formula is: FV = P *rac{(1 + r)^n - 1}{r}
Where:
FV is the future value of the annuity.
P is the payment amount per period.
r is the interest rate per period.
n is the total number of payments.
Since contributions are made monthly, the annual interest rate (2% or 0.02) is divided by 12 to get the monthly rate, and the total number of contributions is multiplied by 12 to account for monthly contributions over 30 years.
For an investment of $250 per month at a monthly rate of 0.02/12, over 360 months (30 years), we get:
FV = $250* rac{(1 + 0.02/12)^{360} - 1}{0.02/12}
Now we calculate the future value:
FV ≈ $250 * rac{(1 + 0.0016667)^{360} - 1}{0.0016667}
FV ≈ $250 * rac{(1.0016667)^{360} - 1}{0.0016667}
FV ≈ $250 * rac{2.0398873 - 1}{0.0016667}
FV ≈ $250 * 623.8469386
FV ≈ $155,961.73
The total amount invested over 30 years is $250 * 12 *30 = $90,000.
The interest earned is therefore:
Interest = FV - Total amount invested
Interest ≈ $155,961.73 - $90,000
Interest ≈ $65,961.73
So the interest earned on the account after 30 years is approximately $65,961.73.

James had a peach that was 98 mm in diameter. One day he watered it with a magical solution, and it grew to 188,869 mm
in diameter.
Approximately how many times as large did the diameter of the peach become after James watered it?
To determine how many times larger the peach got, you will divide the new diameter by the original diameter length.
188869/98 = 1927.2
The new diameter is approximately 1927 times longer.
To convert this to scientific notation, move the decimal point from the end (on the right) to between the 1 and the 9 to get 1.927.
Then count the number of decimal places you moved to get there, because this represents how many groups of 10 you adjusted your place value by and then becomes your exponent in scientific notation.
1.927 x 10^3 times is the answer in scientific notation.

A pedestal on which a statue is raised on is a rectangular concrete solid measuring nine
feet long, nine feet wide, and six inches high. How much is the cost of the concrete in the
pedestal, if concrete costs $70 per cubic yard?
Answer:
The cost of the rectangular concrete solid is $104.87Step-by-step explanation:
If the pedestal on which a statue is raised on is a rectangular concrete solid measuring nine feet long, nine feet wide, and six inches high, the volume of the rectangular concrete solid will be expressed as shown;
Volume of the rectangular concrete solid = Length * Width * Height
Given Length = 9ft, Width = 9ft and Height = 6inches
Converting all the units to yards
Given 1ft = 0.333yard
Length = 9 * 0.333 = 2.997yards
Width = 9* 0.333 = 2.997yards
Also given 1inch = 0.0278yard
Height = 6 * 0.0278yards = 0.1668yards
Volume of rectangular concrete solid in cubic yards = 2.997*2.997*0.1668
Volume of rectangular concrete solid in cubic yards = 1.4982cubic yards
If concrete costs $70 per cubic yard, the cost of the rectangular concrete solid will be 1.4982 *$70 = $104.87
