The total number of snowstorms is 60.

If 65% caused power outages, then the 21 storms that didn't represent 35% because 65%+35%=100%. You can set up a proportion (35/100=21/?) and use cross multiplication to find the total number of snowstorms. So, 21x100=2,100 and then 2,100 divided by 35 is 60.

if the area of a rectangle is represented by 25x^3y^6 and its width is represented by 10xy, express the length of the rectangle
iren [92.7K]

The length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.

The area of a figure is the total space enclosed in two dimensions within its boundary.

The area of a rectangle is given as, area = length*width.

In the question, we are given that the area of a rectangle is represented by 25x³y⁶ and its width is represented by 10xy, and are asked to express the length of this rectangle in terms of x and y.

We know that the area of a rectangle is given as, area = length*width.

Substituting the known values in the equation, we get:

25x³y⁶ = length*10xy.

Rearranging this equation, we get:

length = 25x³y⁶/10xy = (5x²y⁵)/2 = 2.5x²y⁵.

Thus, the length of the rectangle in terms of x and y, given that its area is represented by 25x³y⁶ and its width is represented by 10xy is <u>2.5x²y⁵</u>.
