the management of a hotel found that they will sell all 800 tickets at 4 dollars per per person for a hour concert for one night
Lesechka [4]

Answer:

Step-by-step explanation:

Let x represent the rate at which the ticket is sold and let y represent the number of tickets sold at that rate.

When x = 4, y = 800

This means that the income from gate takings at this rate is 4 × 800 = $3200

For each 1 dollar increase in the gate fee,management expects 100 fewer customers to buy tickets. It means that the amount earned would be (x + 1)(y - 100)

For the amount to be $3500, it means that

(x + 1)(800 - 100) = 3500

700(x + 1) = 3500

x + 1 = 3500/700 = 5

Therefore, management should charge $5 per person for gate fee so that it collects 3500 dollars from gate takings.

Find X. <br> pls &amp; thank you :)
diamong [38]

Answer:

<u>The correct answer is D. 69</u>

Step-by-step explanation:

Let's recall that if an exterior angle has its vertex where two rays share an endpoint outside a circle, the measure of that exterior angle is found by dividing the difference between the measures of the intercepted arcs by two.

Therefore, we have:

x = (Measure of arch CD - Measure of arch BD)/2

Replacing with the real values:

x = (210 - 72)/2

x = 138/2 = 69°

<u>The correct answer is D. 69</u>
