An isosceles triangle has legs that are each `x` inches long and a base that is `y` inches long. The perimeter of this triangle is 38 inches. The base is 8 inches shorter than the length of a leg. How long are the sides of the triangle?

15.333 inches

Step-by-step explanation:

First find the value of “y" which is the base and it is 8 inches shorter than the length legs of the triangle.

y = x - 8

Then substitute the values in the formula for the perimeter of an isosceles triangle.

Perimeter = 2 (L) + b

38 = 2 (x) + x - 8

38 = 2x + x - 8

38 = 3x - 8

38 + 8 = 3x

3x = 46

x = 15.333 inches

x is the length of the triangle and it's actual value is 15.333 inches

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
