Answer:

The two options yield the same price at 25 days.

Step-by-step explanation:

With the information provided, you can say that the option A would be equal to option B, which would be:

225-1x=250-2x, where x is the number of days that the item does not sell

Now, you can solve for x:

-1x+2x=250-225

x=25

According to this, the answer is that the two options yield the same price at 25 days.

Which expression is NOT equivalent to 125.78 ÷ 1.23?
Viefleur [7K]

Answer:

Choice C.

Step-by-step explanation:

For an expression to be equivalent you need to multiply or divide the  2 numbers in the original expression by the same number.

For example A is equivalent because both 125.78 and 1.23 have been multiplied by 100.

The odd one out is C because 125.78 has been divided by 100 but 1.23 has been multiplied by 10.

Silver scooter finds that it costs $300 to produce each scooter and the fixed costs are $750. The price is given by p=900-x, whe
Nady [450]
Cost = 300 x + 750 , where x is the number of the scooters;
Price = 900 - x
Profit = x ( 900 - x ) - ( 300 x + 750 ) =
= 900 x - x² - 300 x - 750 = - x² + 600 x - 750
d (Profit) = - 2 x + 600
- 2 x + 600 = 0
x = 600 : 2
x = 300
The company must produce 300 scooters to maximize the profit.
The maximum profit is:
- 300² + 600 · 300 - 750 = $89,250

What is the probabiWhich value cannot represent the probability of an event occurring?
iren2701 [21]

Given problem:

   Which value cannot represent the probability of an event occurring?

      Values:

            \frac{1}{100}    0.29    \frac{85}{100}   Three-halflity

Probability is the likelihood of an event to occur.

For an event that we are sure of occurring, the probability value is 1, and those that cannot occur have a probability value of 0.

  The probability of any event is usually a fraction between 1 and 0.

So we can see that the odd one is the  Three-halflity which is clearly greater than 1.

RSTU is a kite m A. 120 <br> B. 60 <br> C. 80 <br> D. 140
Ket [755]

Answer:

B. 60

Step-by-step explanation:

a quadrilateral always adds up to 360°. so you add up all angles then subtract your sum from 360. 140+80=220, now add angle U which is a congruent angle to angle s so 220+80=300. now 360-300=60
