Answer:
Perimeter= 12y units
3y(4) = 12y
Step-by-step explanation:
3y + 3y + 3y + 3y= 12y

Step-by-step explanation:
Correlation describes the relationship between two quantitative variables and both variables are quantitative.
Answer:
3 hours
Step-by-step explanation:
To solve this we can first find out how many minutes is 1/5th of an hour which is: 12 mins.
Now we know it will take 15 sets of 12 minutes to water the full lawn so we can multiply 15*12 to get our answer.
15*12 = 180
Now we divide 180 (minutes) by 60 (minutes) to find out how many hours that is:
180/60 = 3 hours
Hope this helped! If possible please leave a thanks so I can continue to help out others :),
comment if you have any questions.
we know that
The measure of the external angle is the semidifference of the arcs that it covers
so
∠MLN=(1/2)*(mayor arc MN-minor arc MN)
Let
x------> minor arc MN
major arc MN=360-x
substitute in the formula above
∠MLN=(1/2)*(mayor arc MN-minor arc MN)
75.86=(1/2)*(360-x-x)------> 151.72=(360-2x)------>360-151.72=2x
x=104.14°
therefore
the answer is
the measure of arc MN (minor arc) is 104.14°
