By the information of all the graphs,
Take any two points from the axis in graph C,
Temperature variation would be: 4-3 / 2-0 = 1/2 = 0.5
It is same which was aked in the question, so that will be your answer.

Option C would be your answer.

Hope this helps!

If you take -3/10 of a number and add 1, you get 10. Write an equation to represent the situation. What is the original number?

Basile [38]

Equation - x = -3/10 + (10－1）

The original number is 9.3 because
x = -3/10 + (10－1）
x = -3/10 + 9
x = 9.3

Sheila, janice, and katen, working together at the same rate, can complete a job in 3 1/3 days. Working at the same rate, how mu

pychu [463]

Answer:

Janice and Karen could do in 1 day:

20% of the job.

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:

$x=\frac{1 person*\frac{10}{3}days }{3 persons}$ (we cancel the unit "persons")
$x=\frac{\frac{10}{3}days }{3}$
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 = $\frac{10}{2}days$
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:
