Answer:
25 Inches
Step-by-step explanation:
Given the table:
We want to determine the missing value on the table.
Let the missing value be x.
1 inch = 2.54 cm
x inch = 63.5
Expressing the above as a ratio
Therefore, the missing value is 25.
The function h is defined by h(x)=60÷x−r, where r is a constant. Find r, if the graph of h passes through the point (−6,−20).
1 answer:
Answer:
r = 10
Step-by-step explanation:
You want to find r such that ...
-20 = 60/-6 -r
r = 60/-6 +20 . . . . . add 20+r
r = -10 +20 = 10
_____
If you mean h(x) = 60/(x -r), then the answer is different.
-20 = 60/(-6-r)
-6-r = 60/-20 . . . . . multiply by (-6-r)/(-20)
-r = -3 +6 = 3 . . . . . add 6, simplify
r = -3 . . . . . . . . . . . . multiply by -1

Answer:
The 3-day pass costs $16.67 more per day than the 7-day pass.
Step-by-step explanation:
The easiest way to do this is to find the cost of each pass for the same amount of days. To do this, we find the lowest common multiple of 3 and 7 which would be 21
Lowest common multiple =
Next we find the cost of each pass for 21 days by multiplying cost of the 7 day pass by 3, and the cost of the 3 day pass by 7
Cost of 7 day pass for 21 days =
Cost of 3 day pass for 21 days =
From this, we know that the difference between the two passes is $350 per 21 days. Since the question asks how much more would the 3-day pass cost <em>per a day</em> than the 7-day pass, we have to divide the difference by 21
We can round this to $16.67. As a result, the 3-day pass costs $16.67 more per day than the 7-day pass.
