An input-output table, like the one shown below, can be used to represent a function. Each pair of numbers in the table is related by the same function rule. That rule is multiply each input number
440 yards x 20 = 8800 yards.
8800 yards is equal to 5 miles.
You would use unit rate for this. If Austin makes $209 in 11 hours, then he makes 209/11 = 19 dollars in 1 hour.
Then, we can make a proportion:
$19/1 hour = $152/ x hours
Cross multiply:
152 = 19x
Solve for x to get:
x = 8 hours.
9m
It said the sides are 25m (x2) and 9m(x2). The width of a rectangle are shorter than the length so 9m.
