Please help put a bunch of points for this question do

Answers

Answer 1

Answer:

Answer:

Label: About 527.9 square centimeters

Aluminum: About 835.7 square centimeters

Step-by-step explanation:

Amount of paper needed for the label:

You can imagine taking off the label and unrolling it, forming a rectangle. The height of this rectangle will be the height of the cylinder, while the length of the rectangle will be the circumference of the cylinder. Therefore, the area of that rectangle will be $2\pi r h= 2 \cdot \pi \cdot 7 \cdot 12\approx 527.9$ .

Amount of aluminum needed for the can:

This time, you need to add in the top and bottom of the can as well, which each have area $\pi r^2$ . Together, they have area $2\pi r^2=2\cdot \pi \cdot 7^2\approx 307.9$ . Adding this to the area of the sides, you get a total of about 835.7 square centimeters.

Hope this helps!

Alfred is taking a trip. He drove 150 mi and then stopped to refuel. He will drive 60 mph to finish his trip. Let x represent the hours it takes for Alfred to complete the rest of his trip, and let y represent the total distance traveled.Complete the function equation that relates Alfred’s total distance traveled to his time.

y =
x +

Answers

Initial distance was 150miles, final distance was 60mph * x(hours it takes for Alfred to complete the rest of his trip)
Therefore y=150 + 60 x

I need an equation for this problem: A small golf club manufacturer is concerned about their monthly costs. The shop has fixed costs of $23,250 per month to run in addition to the $145 in materials per set of golf clubs produced. If the company wants to break-even making 100 sets of clubs per month, what should they charge for each set? Recall that the break-even point is when revenue equals costs. I solved it and the answer is 377.50 but i need a proper equation for my answer

Answers

100 = number of sets of clubs manufactured per month
S = sell-price for a set of clubs

Expenses per month = 23,250 + 145(100) = 37,750

Revenue per month = 100 S

Break-even when Expenses = Revenue

100 S = 37,750
