Your sports team needs to raise money for a trip to Canada for a tournament, and you decide to have a spaghetti fund fundraiser.

You spend $60 on utensils (plates, cups, silverware, napkins) and $140 on food. You charge $8 per ticket. You need to raise $400 (after paying for your meal expenses) for your trip.

A.) 600=8x where x equals the number of tickets

You spent $200 on utensils and food, so that needs to be added to the $400 dollars you need to raise.

b.) Solve for x using the above equation:

x=75 tickets

A graphing calculator is recommended. A grain silo consists of a cylindrical main section and a hemispherical roof. If the total
eimsori [14]

Answer:

11.28 ft

Step-by-step explanation:

The volume of a cylinder can be written as;

Volume V1 = πr^2 h

The volume of an hemisphere can be written as;

Volume V2 = (2/3)πr^3

The total volume of the silo is;

V = V1 + V2

V = πr^2 h + (2/3)πr^3

Given;

Volume of silo V= 15000 ft^3

Height of cylinder part h = 30 ft

Substituting the values;

V = πr^2 h + (2/3)πr^3

15000 = 30πr^2 + (2/3)πr^3

15000/π = 30r^2 + (2/3)r^3

2r^3 + 90r^2 - (15000×3/π) = 0

Solving the equation, we have;

r = 11.28 ft or -15.61 ft or -40.67 ft

Since the radius cannot be negative;

Radius r = 11.28 ft

It is recommended that one fire extinguisher be available for every 6000 ft.² in a building right and solve an equation to deter
irina [24]
6000x = 135000; x ≈ 23.

We are required to have one fire extinguisher for every 6000 ft of space in the building; this means we need to find out how many 6000-ft spaces we have in 135000.

Solving this equation, we divide both sides by 6000:
6000x/6000 = 135000/6000 = 22.5 ≈ 23

Difference of Squares gives which complex factors for the expression x² +11?
77julia77 [94]

Answer:

Step-by-step explanation:

Discussion

i has to appear somewhere. That lets D and B out. They are both wrong.

C has only one i. It can't be right either. You need 2 i-s which will multiply to +1 when squared. That leaves you with a.

The way a is written, it can't be the answer either. For one thing, that 2 makes the answer question at best.

I would say there is no correct answer. Could you check the question? Also it would be a good idea to ask your instructor how this works, in case I'm wrong.

If i got 10$ and spent it on a 2$ drink how much would i have
Marrrta [24]

Hi there!

This is very simple, so here's how to complete this math problem.

It looks like you're taking money away, so...

If you have 10$ and you spent 2 of them, the word 'spent' is a subtraction word, so we would subtract.

10$ - 2$ = 8$

So, therefore, you would still have 8 dollars left. :)

Hope this helps! :D
