A forest clearing is in the shape of an isosceles triangle with a base of 75 feet. The perimeter of the forest clearing is 235 feet. How long is each of the equal sides of the forest clearing?

The length of each of the equal sides of an isosceles triangle are 80.

Explanation:

Given that the forest clearing is in the shape of an isosceles triangle with a base of 75 feet.

The perimeter of the forest clearing is 235 feet.

We need to determine the length of each of the two equal sides.

Length of the two sides.

Let x denote the length of each of the equal sides.

The value of x can be determined using the perimeter formula.

Perimeter of the triangle = Sum of all the three sides of the triangle.

Thus, we have;

Thus, the value of x is 80.

Hence, the length of each of the equal sides of an isosceles triangle are 80.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
