Answer: Irrational</h3>
We cannot write sqrt(12) as a fraction of two whole numbers
Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).
Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
Answer:
The answer is below
Step-by-step explanation:
1. COST Mr. Rivera wants to purchase a riding lawn mower, which is on sale for 15% off the marked price. The store charges sales tax 6.5% on all sales. Write a function p(x) that represents the price after a 15% discount. Write a function t(x) that represents the total cost with sales tax. Write a composition of functions that represents the total cost of a riding lawn mower on sale. How much will Mr. Rivera pay for a riding lawn mower that has a marked price of $3000?
Solution:
a) Let x represent the marked price and p(x) represent the price after discount. Since a discount of 15% is given, the price would be:
p(x) =
b) If x = discounted price and t(x) = total cost with sales tax, then:
t(x) =
c) Let t(x) represents the total cost with sales tax
Answer:
26
Step-by-step explanation:
One person can pack 45 cartoons per hour
Therefore the number of people needed to pack 1200 cartons can be calculated as follows
= 1200/45
= 26.66
= hence 26 people are needed to pack 1200 cartoons
