In simplest form, what is the ratio of triangles to circles?

a set of shapes is arranged as follows: triangle, circle, square, circle, circle, square, triangle, circle.

Let

T-------> number of triangles in the data set

C-------> number of circles in the data set

S-------> number of squares in the data set

N------> number of total elements in the data set

we have

we know that

The ratio of triangles to circles is equal to

Divide by boths numerator and denominator

therefore

the answer is

the ratio of triangles to circles is equal to

yes yes yes yes yes yes yes yes yes

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.
