10.) Jamila is making a triangular wall
with building blocks. The top row has one
block, the second row has three blocks, the
third row has five, and so on. How many
rows can she make with a set of 100
blocks?

the amount of rows she can make with a set of 100 blocks is 10 rows

Step-by-step explanation:

this question is an example of a Arithmetic Progression

I.e 1, 3, 5, ............ 100

therefore,

1st term (a) = 1

common difference (d) = 2 (either 3 - 1 or 5 - 3)

from the formula

by taking the square root of both sides

N =

N = 10

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.
