It costs Marie $25 overhead and then an additional $1.25 to make each barrette. She charges $3.50 for each one. Write a function to model Marie's profit?
Given is the Overhead charges = 25 dollars.
Making charge of each barrette = 1.25 dollars.
Let's assume the number of barrette that she makes = x
So the Cost function would be, C(x) = 1.25x + 25.
She sell each piece for 3.50 dollars.
So the Revenue function would be, R(x) = 3.50x
We know the Profit function is given by the difference of Revenue function and Cost function.
Profit function = Revenue function - Cost function
P(x) = R(x) - C(x)
P(x) = 3.50x - (1.25x + 25)
P(x) = 3.50x - 1.25x - 25
P(x) = 2.25x - 25
Hence, Marie's Profit would be P(x) = 2.25x - 25.

The density of gold is 19.32 grams per cubic centimeters. Jimmy Jackson built a pyramid made out of pure gold about 2.13 meters tall with a mass of 298.7 kilograms. If the base of the pyramid is a square, what are the dimensions of the base of the pyramid?
Final answer:
By calculating the volume of the gold pyramid using the given mass and density of gold, and then applying the volume of a pyramid formula, we find that the dimensions of the square base are approximately 14.75 cm by 14.75 cm.
Explanation:
To find the dimensions of the base of the pyramid made out of pure gold, we need to calculate the volume of the gold pyramid using the known mass and density of gold then use that volume to find the base area and, consequently, the dimensions of the base.
The density (d) of gold is given as 19.32 g/cm³, and the mass (m) of the pyramid is 298.7 kg. First, we convert the mass from kilograms to grams (since the density is in grams per cubic centimeter):
m = 298.7 kg * 1000 g/kg = 298700 g
Next, we use the formula for density d = m/V to find the volume (V) of the gold pyramid. Rearranging the formula to solve for V gives:
V = m/d
V = 298700 g / 19.32 g/cm³
V ≈ 15461.8 cm³
Since the base of the pyramid is a square and the pyramid is 2.13 meters tall, we can use the volume of a pyramid formula V = (1/3) * base area * height to find the base area. We first convert the height from meters to centimeters:
height = 2.13 m * 100 cm/m = 213 cm
Now applying the pyramid volume formula and solving for the base area, we have:
base area = 3V / height
base area = 3 * 15461.8 cm³ / 213 cm
base area ≈ 218.2 cm²
To find the dimensions of the square base, we take the square root of the base area:
side length = √(base area) ≈ √(218.2 cm²) ≈ 14.75 cm
Therefore, the dimensions of the base of the gold pyramid are approximately 14.75 cm by 14.75 cm.

Aubrey is painting a mural of an ocean scene. The triangular sail on a sailboat has a base of 4 feet and a height of 6 feet. Aubrey will paint the sail using a special white paint. A can of this paint covers 10 square feet. How many cans of white paint will Aubrey need?
Final answer:
Aubrey requires 2 cans of white paint to cover the triangular sail with an area of 12 square feet, given that one can covers 10 square feet.
Explanation:
Aubrey is painting a triangular sail as part of a mural with a base of 4 feet and a height of 6 feet. To calculate the area of the triangle, the formula is 1/2 × base × height. Thus, the area is 1/2 × 4 × 6, which equals 12 square feet. One can of special white paint covers 10 square feet. Therefore, Aubrey will need to use 2 cans of paint to cover the entire sail, since you can't purchase a fraction of a can.

Convert the ratio of sheep to pigs below to the ratio of the pigs to total animals (sheep and pigs) 5:9
Answer:
The ratio of pigs to total animals is 9:14 or 9/14.
Step-by-step explanation:
Given that the total number of sheep = 5
The total number of pigs = 9
From that, the given ration of sheep to pigs is 5:9
Now, the total number of animals = no. of pigs + no. of sheep = 5+9 = 14.
So, to express the ratio of pigs to the total number of animals =
no. of pigs: total no. of animals = 9:14.
Therefore, the ratio of pigs to the total number of animals is 9:14.

Phineas is the lead research scientist in a lab and responsible for ordering supplies and equipment. The lab is out of petri dishes, so Phineas orders 185 of them. The lab uses 12 petri dishes each day.
Answer:
The relationship is between the days that have gone by and the number of petri dishes. The point (0, 185) means that if 0 days have gone by there are 185 petri dishes. The number of petri dishes decreases by 12 each day, so the slope is –12. Use the slope-intercept form to write the equation y = –12x + 185.

For a single roll of two dice, are rolling a sum of 6 and rolling doubles mutually exclusive events?
Answer: They are not mutually exclusive events.
Step-by-step explanation:
Let A be the event of getting a sum of 6 on dice.
Let B be the events of getting doubles .
A={ (1,5), (2,4), (3,3), (4,2), (5,1) }
B = { (1,1) , (2,2), (3,3), (4,4), (5,5), (6,6) }
Since we know that Mutaullty exclusive events are those when there is no common event between two events.
i.e. there is empty set of intersection.
But we can see that there is one element which is common i.e. (3,3).
So, n(A∩B) = 1 ≠ ∅
Hence, they are not mutually exclusive events.
Answer:
They are not mutually exclusive events.

Final answer:
Since the area of one side is 1.44 m², the total surface area is 8.64 m².
Explanation:
To find the total surface area that will be painted on a cube-shaped table with an edge length of 1.2 m, we use the formula for the surface area of a cube, which is 6 times the area of one side.
Calculating the area of one side (1.2 m × 1.2 m) gives us 1.44 m². Multiplying this by 6 (6 × 1.44 m²) gives the total surface area which is 8.64 m². Therefore, the correct answer to drag and drop into the box is 8.64 m².
