Answer:
Janice and Karen could do in 1 day:
Step-by-step explanation:
To identify how much of the job could janice and caren do in 1 day, first, we must find how much of the job make just 1 person at the same rate:
If three persons make a job in 3 1/3 days, 1 person make the job in x:
- 3 persons ⇒ 3 1/3 days or 10/3 days
- 1 person ⇒ x
Then:
(we cancel the unit "persons")
- x = 10 days
Just a person would need 10 days to complete a job, now, we're gonna divide this value in 2 to obtain the time that need two persons to complete a job:
- Time to complete a job between 2 persons =

- Time to complete a job between 2 persons = 5 days
How two persons need 5 days to complete a job (in this case, the two persons are Janice and Karen), we can make a simple rule of three to obtain the percentage made in 1 day:
- 5 days ⇒ 100% of a job
- 1 day ⇒ x
Then:
(you can use the % if you want, the result is the same)

As you can see, <u><em>Janice and Karen just in a day could do 20% of the job</em></u>.
The slope is undefined because it is a vertical line on the x axis at 0. Its a straight line going up
Answer:
Step-by-step explanation:
well... all the least common factor have to write in the increasing order.
So, following this picture, we have to write in this order:
2 x 2 x 2 x 3 x 5
Answer:
15
Step-by-step explanation:
Let Rama's current age be x.
Rama's Age 4 years ago = x - 4
3/5 of Rama's Age = 3/5 x
Difference = 0
(x - 4) - 3/5 x = 0
2/5 x = 4
x = 10
Rama's Age after 5 years = 10 + 5
= 15
Rama's Age After 5 Years is <u>1</u><u>5</u>
A shadow measures 88 m: d = 88 m.
The angle : α = 32°
We will use trigonometry:
h / d = tan α
h / 88 m = tan 32°
h / 88 m = 0.62489
h = 88 m * 0.62489
h = 54.9885 m ≈ 55 m
Answer: The approximate height of a building is 55 meters.
