Write a story for this graph. ( Use the outline plz)
Katyanochek1 [597]

Answer:

Jack is evil.

Step-by-step explanation:

Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.

(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)

(80pts) The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people
allsm [11]

Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class (\frac{A's}{B's})

\frac{2}{5} = \frac{A}{40}

Cross multiply

2 * 40 = 5 * A

80 = 5A

Isolate A by dividing 5 to both sides

80/5 = 5A/5

16 = A

If 40 people in the class got B's then 16 people got A's

Hope this helped!
