Answer:
Step-by-step explanation:
A nickel is worth 5 cents. Converting to dollars, it becomes
5/100 = $0.05
A dime is worth 10 cents. Converting to dollars, it becomes
10/100 = $0.1
Let x represent the number if nickels.
Let y represent the number of dimes.
He has no more than 19 coins. This means that
x + y ≤ 19
He has no less than $1.30 combined. This means that
0.05x + 0.1y ≥ 1.3
If Nolan has 5 nickels, then, substituting x = 5 into x + y ≤ 19, it becomes
5 + y ≤ 19
y ≤ 19 - 5
y ≤ 14
substituting x = 5 into 0.05x + 0.1y ≥ 1.3, it becomes
0.05 × 5 + 0.1y ≥ 1.3
0.25 + 0.1y ≥ 1.3
0.1y ≥ 1.3 - 0.25
0.1y ≥ 1.05
y ≥ 1.05/0.1
y ≥ 10.5
Therefore, all possible values for the number of dimes that he could have would be
10.5 ≤ y ≤ 14

Answer:
Step-by-step explanation:
We have to find the points that are on the graph by finding the order pair (x, y) We are given the x value, so substitute x in the given equation f(x) and find y.
The graph is a line
Total tickets = 60
Tickets sold = 65% of 60 = 0.65 x 60 = 39
Answer: Marvy has sold 39 tickets.
Answer:
6.5in
Step-by-step explanation:
find the area of the shaded regions
fine the surface area of the square
A = 2×2
A = 4
find the area of the triangle
A = 1/2bh
A = 1/2×2×2.5
A = 2.5
add the areas
2.5+4 = 6.5
