Jack wants to fill a rectangular box with sand. the length of the sand box is 3 feet, width is 6 inches, and height is 2.4 inches. each bag of sand contains 0.15 cubic foot of sand. how many bags of sand will jack need to fill the box completely? [1 foot = 12 inches] numerical answers expected

3 feet = 36 inches

36 x 6 x 2.4 = 518.4 cubic inches

1 cubic foot = 1728 cubic inches

518.4/1728 = 0.3 cubic feet

0.3/0.15 = 2

 he will need 2 bags

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
