The cube and rectangular prism.
Step-by-step explanation:
The triangular prism has 5 and the other two both have 8.
None of the shapes mentioned in the question, a cube, a rectangular prism, or a triangular prism, have more than six faces. For more complex shapes like Icosahedron, they do carry more than six faces.
Explanation:The student's question is about understanding which among the shapes - a cube, a rectangular prism, and a triangular prism - has more than six faces. To answer this, we should first understand that a cube and a rectangular prism (or cuboid) both have 6 faces and a triangular prism also has 5 faces only. Hence, none of these shapes deliver more than 6 faces as specified in the question. For a three-dimensional shape to have more than 6 faces, one has to move towards more complex shapes. For example, the provided reference suggests Icosahedron, a shape with 20 faces is an example of a shape with more than six faces.

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

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).

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.

Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 7 years?
Answer:
$120.1355
Step-by-step explanation:
We can model this as an exponencial function:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
For this case, we have that Po = 900, r = -25% = -0.25 and t = 7, so we can find the value of P
P = 900 * (1 - 0.25)^7 = $120.1355
The price after 7 years will be $120.1355.
To calculate the value of Dan's computer after 7 years of 25% annual depreciation, we use the exponential decay formula. The approximate value of the computer after 7 years is $120.14.
To calculate the approximate value of Dan's computer after 7 years with a depreciation rate of 25% per year, we can use the formula for exponential decay:
[tex]V = P(1 - r)^t[/tex]
V is the future value of the computer.P is the original price of the computer ($900).r is the rate of depreciation (25% or 0.25).t is the time in years (7 years).Plugging in the values, we get:
[tex]V = $900(1 - 0.25)^7[/tex]
[tex]V = $900(0.75)^7[/tex]
V = $900 * 0.1334838867
Therefore, the approximate value of the computer after 7 years is:
V = $120.14
Dan can expect the computer to be worth approximately $120.14 after 7 years.

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

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
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.

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.

Topic: Volume
Focus on question 12
Answer: 0.6 meters cubed.
Step-by-step explanation:
To find the answer to this, first find the volume of the cube.
Volume is equal to the side cubed. In this case, 1 cubed is 1, so the area of the cube is 1 meter cubed.
The depth of the water is 0.4 meters, so the water makes a shape of a rectangular prism, where the length and width are 1 meter, and the height is 0.4 meters.
The volume of a rectangular prism is l*w*h, so the volume of this rectangular prism is 0.4 * 1 * 1, or 0.4 meters cubed.
As such, the volume of the air in the tank is 1 - 0.4, or 0.6 meters cubed.

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.
