Hello!
Robin can clean 72 rooms in 6 days. How many rooms can Robin clean in 9 days?
We have a proportional magnitude (directly proportional), if we increase the number of days for cleaning, obviously we will have more rooms cleaned, then:
clean rooms __________ days
72 ----------------------------------- 6
y ------------------------------------- 9
multiply the means by the extremes
Answer:
108 clean rooms in 9 days

Answer:
-2
Step-by-step explanation:
using rise over run, we can see that the rise is two and the run is 1. that makes this 2/1 or 2. but since the line is deacreasing from left to right the slope is negative. this means that the slope is -2. hope this helped. :)
On that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
<h3>Define the term comparison of numbers?</h3>
- In arithmetic, comparing numbers is described as the process or method of determining whether one number is smaller, bigger, or equal to some other number based on their values.
The equation u = 0. 99c depicts the value of the US dollar in relation to the Canadian dollar on a specific day.
- c = the Canadian dollar's value
- u denotes the value of the US dollar.
From the equation,
For Australian dollar; (from table)
u = 0.95 c -->
a = 1/0.95 u
a = 20/19 u
(20/19u - u)/ u = 1/19 ....1
For Canadian dollar:
u = 0. 99c
c = 1/0.99 u --> c = 100/99 u
Thus,
(100 u / 99 - u)/ u = 1/99 .....2
From 1 and 2]
1/19 > 1/99
Thus, on that specific day, the US dollar was worth more than the Canadian dollar and less than the Australian dollar.
