Answer:
3 hours + 5hours = 8 hours ÷ 2 =
4 hours is your answer.
Step-by-step explanation:
If you have 2 people working and need to know how long it would take them to finish a job. Working together on the same job, you add each of their total hours to do the job alone,, 5 + 3 = 8, then divide the 8 by 2 people
equals 4 hours for 2 people on 1 job.
Answer:
C, D, J
Step-by-step explanation:
Points to the left of the y-axis have a negative x- value
Points to the right of the y-axis have a positive x- value
Points on the y-axis have an x- value of zero
C(- 4, 5), D(- 9, 9 ), J(- 9, 0) ← are the coordinates of the points
All have a negative x- value
We know that
Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)
in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)
see the attached figure
the answer is the option

4/6 chance or 2/3 chance. i’m not sure if this is like probability i’m at a middle school level
