M is directionly proptional to r squared

sergejj [24]

9514 1404 393

Answer:

A) 504

B) 8

Step-by-step explanation:

The statement of proportionality can be written as the equation ...

m = kr²

Then we can find k from ...

k = m/r² = 14/2² = 7/2

That is, ...

m = (7/2)r²

Using this relation, we can find m for r=12:

m = (7/2)·12² = 7·72

m = 504 . . . for r = 12

And, we can use the same equation to solve for r when m=224.

224 = 7/2·r²

r² = 64

r = √64

r = 8 . . . for m = 224

A furniture store is having a weekend sale and is offering a 20% discount on patio chairs and tables. The sales tax on furniture

dalvyx [7]

First, we subtract 20% of the amount from x, so the initial cost of the furniture should be 80% of x or 0.80x. Then, due to the sales taxs, this amount should be added with 6.25% of itself. Such that,
A = 0.80x + 0.0625(0.80x)
= 0.85x

A theater rents their space for $300 per night. If the company charges $9 per ticket, then what is the least number of tickets t

vitfil [10]

Answer:

Company needs to sell at least 34 tickets in order to make a profit.

Step-by-step explanation:

Given:

Rent for the space = $300

Cost per tickets = $9

Let the number of tickets sold be 'x'

We need to find the least number of tickets to be sold to make profit

Now total profit can be made if amount which is made after selling number of tickets is greater than 300.

Hence the equation can be framed as,

$9x\geq300$

Solving the equation to find the value of x we get;

We will use Division property and divide both side by 9 we get;

$\frac{9x}{9}\geq\frac{300}{9}\\\\x\geq33.33$

Tickets which need to be sell cannot be in point value hence rounding to whole number we get;

$x\geq34$

Hence Company needs to sell at least 34 tickets in order to make a profit.
