Answer:
Step-by-step explanation:
total height, H = 113 inches
height of each stair case, h = 7.25 inches
Number of stair case, n = total height / height of each stair case
n = 113 / 7.25 = 15.6
Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714
10 n = C
Finding the total would simply be multiplying the cost of the tickets by number of students.
