Evgen [1.6K]

The complete question is;

A paintball court charges an initial entrance fee plus a fixed price per ball.

P represents the total price (in dollars) as a function of the number of balls used n.

P = 0.80n + 5.50

How much do 10 balls cost?

Answer:

Cost of 10 balls = 8 dollars

Step-by-step explanation:

We are told that;

total price in dollars is given as a function of the number of balls

p = 0.8n + 5.5

Where n is number of balls.

We are told that the price above is price of number of balls plus entrance fee.

Thus, 5.5 dollars is the entrance fee while 0.8n dollars is the price for n number of balls.

Thus,for 10 balls,

Price of 10 balls will be 0.8 x 10 = 8 dollars

The area of triangle PQR is 273 cm. Given that PQ = 12.8cm and PQR = 107°, find QR.​
storchak [24]

\text{Area of triangle} = \dfrac 12 \times PQ \times QR \times  \sin \angle PQR \\\\\\\implies  273= \dfrac 12 \times 12.8 \times QR \times \sin 107^{\circ}\\\\\implies 273 = 6.4 \sin 107^{\circ}  \times QR\\\\\\\implies QR = \dfrac{273}{6.4 \sin 107^{\circ}} = 44. 606~~ \text{cm}
