Answer:
John need to remove <u>4760 cubic feet</u> of dirt.
Step-by-step explanation:
Given:
John is digging a hole for a swimming pool,the hole will be 28 feet long, 5 feet wide, 34 feet wide.
Now, to find the cubic feet of dirt John need to remove.
Length = 28 feet.
Width = 5 feet.
Height = 34 feet.
<u><em>As the swimming pool is in the shape of a rectangular prism.</em></u>
So, we put formula of volume to get the cubic feet of dirt need to remove:



Therefore, John need to remove 4760 cubic feet of dirt.
6 8/48 and 2 7/48 equal 8 15/48
Answer:
Given,
2 cups of yellow paint is needed for every 3 cups of red paint to make a batch of orange paint,
So, the ratio of yellow paint and red paint in a batch of orange paint = 2 : 3
Make two number lines,
First one represents the multiple of 2 and second one represents the multiples of 3,
By the double number line ( shown below ),
It is clear that,
For 3 batches of orange paint, 6 cups of yellow paint and 9 cups of red paint are needed.
x > -3
x < 3
<em><u>-3 < x < 3</u></em>
question didn't mention about "x is real number, or positive, or negative etc".. so we can't say anything more
for example: x can be -2,-1,0,1,2
but if only positive, x can be = 1,2
" " negative, x can be = -1, -2
Hope this helps ^-^
