In a recent year,the weather was pretty cloudy 2/5 of the days. Assuming there are 365 days in a year, how many days were partly
Mariana [72]
We can solve this pretty easily using a proportion where x equals the number of cloudy days in the year:

2/5 = x/365
Now cross multiply:
730 = 5x
And finally divide both aides by five:
146 = x
So 146 days of the year were cloudy.

Hope I helped, and let me know if you have any questions!

What is the equation of the line that contains the
slavikrds [6]

Answer:

B

Step-by-step explanation:

<em>y</em><em>=</em><em>kx</em><em>+</em><em>m</em>

<em>k</em><em>=</em><em>y2</em><em>+</em><em>y1</em><em> </em><em>/</em><em> </em><em>x2</em><em>+</em><em>x1</em><em> </em>

(3,5) and (7,9)

k=(9-5)/(7-3)=4/4=1

Now we want to find out what <em>m</em><em> </em>is. This is by inserting a point in the equation of the line y=kx+m.

so I'll pick (3,5)

5=1×3+m

m= 2

To check if it's correct we could try it with the other point, (7,9).

9=1×7+m

m=2

Therefor the equation would be. y=1x+2
