Let length = L m and width = W m. Then:-

LW = 350

2L + 2W = 90

from the above equation:-

L = (90 - 2W) / 2

Substituting for L in the first equation:-

W(90 - 2W) / 2 = 350

90W - 2W^2 = 700

2W^2 - 90W + 700 = 0

(2W - 70)(W - 10) = 0

W = 35 , 10

therefore L = 10, 35

Answer Length = 35m and width = 10 m

The circumference of a circle is 15ft. What is the length of the radius? Use 3.14 for pi. Round your answer to the nearest tenth
dybincka [34]
The circumference of the circle is determined by using the equation, C = 2πr. From this, the value of r may be solved by rearranging the equation to, r = C/2π. Substituting the given values,
                                          r = 15 ft / (2 x 3.14)
The value of r is 2.3885 ft. Thus, the answer to the question is 2.4 ft.

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3
