Base of isosceles triangle is 1/4 the length of one of its legs. the perimeter of triangle is 16, what is the length of the base.

7.88 or 7 7/8

Step-by-step explanation:

Perimeter= sum of two equal sides + third side

; P= 2a + b

a = P/2 -b/2

a = 16/2 - 1/4/2

a = 16/2-2/4

a = 63/8

a= 7.88 or 7 7/8

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.
