A town has accumulated 4 inches of snow, and the snow depth is increasing by 6 inches every hour. A nearby town has accumulated
zimovet [89]

9514 1404 393

Answer:

  2 hours

Step-by-step explanation:

The initial difference in depth is 10-4 = 6 inches. The difference in snowfall rates is 6-3 = 3 inches per hour.

At that rate, the difference in depth will be made up in ...

  (6 in)/(3 in/h) = 2 h

In 2 hours the snowfall in the two towns will be equal.

_____

You could write equations for depth, then equate them.

  d1 = 4 +6h

  d2 = 10 +3h

  d1 = d2 . . . . . . . . . . for some value of h the depths will be equal

  4 +6h = 10 +3h

  h(6 -3) = 10 -4 . . . . . subtract 3h+4 from both sides

  h = 6/3 = 2

Snowfall will be equal in 2 hours.

A square is changed into a new rectangle by increasing its width by 2 inches and decreasing its length by 2
solniwko [45]

Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.

Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;

Area = L x W

The length and the width both measure 8 inches (all sides of a square are equal in length).

Area = 8 x 8

Area = 64

Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;

Area = L x W

Area = 10 x 6

Area = 60

Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.
