Answer:
48 minutes
Step-by-step explanation:
Given that:
Time taken by Janet = 3 hours
Janet's rate = 1/3 job / hour
Time taken by Garry = 2 hours
Garry's rate = 1/2
Rate of working together :
1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour
If Janet works for one hour before Garry joins ;
1/3 of the job has been done by Janet
1 - 1/3 = 2/3 of the job left
Hence to finish the job together, it will take :
Fraction of JOB left ÷ rate of working together
(2/3 ÷ 5/6)
= 2 /3 * 6/5
= 12 / 15
= 4 / 5 hours
To minutes
(4/5) * 60
= 240/5
= 48 minutes
Answer:
y = −7x + 17
Step-by-step explanation:
y + 4 = -7 (x - 3)
add -4 to both sides
y + 4 + -4 = -7x + 21 + -4
y = -7x + 17
Answer:
Step-by-step explanation:
The area of a rectangle can be found with the following formula:
Where "l" is the length and "w" is the width.
In this case you can identify in the figure given in the exercise that:
You know that the area of that rectangle is the following:
Therefore, knowing those values, you can substitute them into the formula and then you must solve for "x" in order to find its value. You get that this is:
Either way you go 180 degrees clockwise or counter clockwise it will land in the same spot
