Answer 2

here is the last one (i hope) :

Zen wants to fill a window box with soil. The length of the window box is 5 feet, width is 6 inches, and height is 9 inches. Each bag of soil contains 0.625 cubic foot of soil. How many bags of soil will Zen need to fill the window box completely?

[1 foot = 12 inches]

Answer for Blank 1:

Answer 3

You are given that f(x) is less than 50 inches
so just solve f(x)<50 for x

Answer 4

for the first one i got c? @freckles

Answer 5

sounds fine since measurements aren't always in integer form

Answer 6

? what do you mean

Answer 7

oh i get never mind srry

Answer 8

how about the second one?

Answer 9

have you found the volume of the window box?

Answer 10

? for the second one

Answer 11

the only other question I see is the one with the window box?
is that not the right problem?

Answer 12

if you want to do the problem with the window box
you need to first find the volume of the window box
and then divide that by the volume of one bag to see how many bags you need

Answer 13

ok

Answer 14

and that is the right problem i got 3 for the answer but i am not sure

Answer 15

@freckles ?

Answer 16

well what did you get for the volume of the window box
and yes I'm still here

Answer 17

I assumed you converted all the lengths given to feet?

Answer 18

then you multiply the width, height, and length to find the volume of the box

Answer 19

so 3 is right?

Answer 20

ok yea sure
I just wanted to see your steps and see if you really understood it
but yea 3 is right

Answer 21

ok thank you
