The answer is 15 distinct pairs of disjoint non-empty subsets.
Acceleration due to gravity is 32.2 ft/s^2
68=32.2t
t=2.11 seconds
h=68t-32.2/2*t^2
h(2.11)=68*2.11-32.2/2*2.11^2
h=71.8 feet
<span>Successive discounts of 20% and 10% are taken on an item priced at $16.
=> Let's find out how much is the discount in all.
=> 16 dollars * .20 = 3.2 dollars
=> 16 - 3.2 = 12.8 dollars.
then another 10% discount,
=> 12.8 * .10 = 1.28 dollars
=> 12.8 - 1.28 = 11.52 dollars is not the price minus the discounts,</span>
Answer:
Number of leashes Bob can make in 2 hours = 7
Number of leashes Bob can make in 1 hour = 7÷2 = 3.5
Let, Bob takes total x hours.
Number of leashes Nina can make in 1 hour = 4
Let, Nina takes total x hours.
∴ The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-
3.5x+4x = 60.
7.5x = 60
This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.
