Answer: False, there are actually 900 different three-digit numbers
========================================================
Explanation:
The three digit numbers span from 100 to 999, including both endpoints.
This means we have 999-100+1 = 900 different three-digit numbers.
You subtract the endpoints (large-small) and add 1 to include the lower endpoint.
Here's a smaller example of why this works: say you had the set {1,2,3,4} and we wanted to count the number of items in this set. Clearly there are 4 items. Note how subtracting the endpoints 4-1 gets us 3 instead, so we add on 1 to include that left endpoint.
Select three options. In a paragraph proof, statements and their justifications are written in sentences in a logical order. A two-column proof consists of a list statements and the reasons the statements are true.
Answer:
it is twice as long(10/12 inches longer
Step-by-step explanation:
1 4/6 make the 6 a 12 and the four a 8. 1= 12/12 so 8+12=20 so 20/12 and 20 is 10/12 more that 10/12 or twice as much.

Answer: Profit = 0.4x - 25
Step-by-step explanation:
Let x represent the number of cookies that he makes and sells.
Profit = Revenue - total cost
Manny purchased a set of cookie cutters for $25. The ingredients for his cookies will cost him $0.35 per Cookie. This means that his total cost of producing x cookies is
0.35x + 25
He plans to sell cookies for $0.75 each. This means that the revenue generated from selling x cookies is 0.75x
Therefore, the equation giving Manny's total profit per cookie as a function of the number of cookies he makes is
Profit = 0.75x - (0.35x + 25)
Profit = 0.75x - 0.35x - 25
Profit = 0.4x - 25
