Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags

kirill [66]

Answer:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Price of one drink is $9.25

Step-by-step explanation:

Let the price of a bag of popcorn be p.

Let the price of a drink be d.

Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:

2p + 2d = 39 ____________(1)

Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:

8p + 10d = 174.50 _________(2)

We now have two system of equations which we can use to find the price of a bag of popcorn and drink:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Multiply (1) by 4 subtract from (2):

8p + 10d = 174.50 _______(2)

-<u> 8p + 8d = 156 </u> __________(1)

2d = 18.50

=> d = $9.25

The price of one drink is $9.25

Two pools are being filled with water. To start, the first pool contains 890 liters of water and the second pool is empty. Water

mars1129 [50]

<span>Let x=amount of time it takes both pipes draining together to empty the pool
First pipe empties at the rate of 540,000/150=3600 liters/min
Second pipe empties at the rate of 540,000/225=2400 liters/min
Together, both pipes empties at the rate of 3600+2400=6000 liters/min, so our equation to solve is:
6000*x=540000 </span>

Find the area of the regular 15-gon with radius 8 mm.

GalinKa [24]

A=(1/2)(r^2)(sin[360/n])(n)
A=(1/2)(8^2)(sin[360/15])(15)
A=(1/2)(64)(sin[24°])(15)
A=(1/2)(64)(0.40673664)(15)
A= 195.2335872
