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:

Step-by-step explanation:
One way would be to find the distance from the point to the center of the circle and compare it to the radius
for
the center is (h,k) and the radius is r
and the distance formula is
distance between
and
is
r=radius
D=distance form (8,4) to center
if r>D, then (8,4) is inside the circle
if r=D, then (8,4) is on the circle
if r<D, then (8,4) is outside the circle
so
the radius is
center is (-2,3)
find distance between (8,4) and (-2,3)
≈4.2
≈10.04
do r<D
(8,4) is outside the circle

Answer:
The cyclist will have traveled 72 kilometers with-in 3 hours.
Step-by-step explanation:
1 mile (s) = 1.60934 kilometer(s)
15 miles = 24.1402// 24 kilometers
by 3 hours:
45 miles = 72/72.4205 kilometers
