Answer:
Answer:
Mary's ticket was less than the original price by 12 percent
Step-by-step explanation:
1. Let's calculate the 20% discount price Mary received:
75 - 0.2 * 75 = 75 - 15 = $ 60
The discounted price is $ 60
2. Let's calculate the 10% service fee to the discounted price:
60 + 0.1 * 60 = 60 + 6 = $ 66
The price including the service fee is $ 66
3. Finally, let's calculate the less percentage than the original price:
Let's use the Direct Rule of Three, this way:
Price Percentage
75 100
66 x
**************************
75x = 66 * 100
75x = 6,600
x = 6,600/75
x = 88
Less percentage = 100 - 88 = 12%
Mary ticket was less than the original price by 12 percent
Y= -3 . Plug the -2 into x. 8x-3y=-7
8(-2) -3y= -7

Kinetic energy, KE = 0.5 mv^2
Where m is the mass
V is the velcocity
First calculate the kinetic energy of the bullet
Ke = 0.5(0.008 kg) ( 370 m/s)^2
Ke = 547.6 J
547.6 J = 0.5( 74 kg) v^2
<span>V = 3.85 m/s</span>
Answer: $67.20
Step-by-step explanation:
56 × 0.2 = 11.2
11.2 + 56 = $67.20
