Answer:

C. a number whose square root is a whole number

Step-by-step explanation:

A number whose square root is a terminating decimal is not a perfect square.

A negative whole number cannot be a perfect square.

A number times itself is squared, the number itself is not a perfect square.

The correct answer is option C, a number whose square root is a whole number. For example: 4 is a perfect square.

\sqrt{4} =2

The square root of a perfect square is always a whole number.

When the admission price for a baseball game was $5 per ticket, 35,000 tickets were sold. When the price was raised to $6, only
zysi [14]

The profit function is P(x) = ( - x² / 5000 ) + 11.9x - 95000.

35,000 baseball game tickets were sold at $5 per ticket.

When the price is raised to $6, then 30,000 tickets were sold.

The variable and fixed costs for the ballpark owners are $0.10 and $95,000 respectively.

Let's say x is the number of tickets sold, and P is the profit.

Then,

P = ax + b

At P = 5,

5 = (35000)a + b                                                                                  ---------(1)

At P = 6,

6 = (30000)a + b                                                                                  --------(2)

Subtracting (2) from (1),

5 - 6 = (35000)a + b - (30000)a - b

- 1 = 5000(a)

a = ( - 1/5000)

So if a = ( - 1/5000),

Then,

5 = (35000)a + b

5 = (35000)( - 1 / 5000 ) + b

5 = - 7 + b

b = 12

Therefore,

P(x) = ( - x /5000) + 12

Now, the profit function is:

Profit = Revenue - Costs

P(x) = R(x) - C(x)

Now, R(x) =  xp(x)

R(x) = x[ ( - x/5000) + 12]

R(x) = ( - x² / 5000 ) + 12x

The fixed cost is F(x) = $95000

Hence, the costs will be:

C(x) = 95000 + (0.10)x

Therefore the profit function is:

P(x) = R(x) - C(x)

P(x) = ( - x² / 5000 ) + 12x - 95000 - (0.10)x

P(x) = ( - x² / 5000 ) + 11.9x - 95000

If a train travels at 80mph for 15 min, what is the distance traveled ?
VMariaS [17]

Answer:

20 miles

Step-by-step explanation:

The formula for distance is

d =rt  where r  is the rate and t is the time

We need to convert the time to hours since the rate is in mph

15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours

d = (80 mph) * .25 hours

d = 20 miles

Gavin agrees to buy a 6 month package deal of monthly gym passes, and in turn receives a 15% discount. Write an algebraic expres
dolphi86 [110]
15% off means 85% on so I would use .85x · 6 = total monthly cost  to represent this problem.  The dot represents times (I did not want to confuse things by using x)

Other ways to express this:

6 x .85x
6(.85x)
.85x (6)
