Answer:
The sandbox can hold 36 cubic feet of sand .
He did not purchase enough sand to fill the sand box .
Step-by-step explanation:
Given : The sandbox measures 6 feet 5 feet by 1.2 feet.
Jodi purchases 20 cubic feet of sand to fill the sandbox.
To Find: How much will the sandbox hold? did Jodi purchase enough sand to fill the sandbox?
Solution :
Since he built a rectangular sand box .
So, Formula of volume of cuboid =
Volume of sandbox =
=
The sandbox can hold 36 cubic feet of sand .
Jodi purchases 20 cubic feet of sand to fill the sandbox.
So, he did not purchase enough sand to fill the sand box .
The amount of sand required more = 36-20
=16 cubic feet
Hence he did not purchase enough sand to fill the box . H e should purchase 16 cubic feet sand more to fill the box completely.
Answer:
Factoring the trinomial: we get the factors
Step-by-step explanation:
We need to factor the trinomial:
We can factor the trinomial by breaking the middle term i.e 13x
Such that adding or subtracting gets the both terms we get 13x and multiplying both terms we get 12x^2
We can break 13x as: 12x and x
Adding them we get 13x and multiplying them we get 12x^2
So,
So, Factoring the trinomial: we get the factors
Answer:
a) Not parallel to y-axis
b) Not parallel to y-axis
c) Parallel to y-axis
Step-by-step explanation:
The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.
The equation of line:
a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.
It is parallel to x-axis. Another two points that can lie on this line are : (5,12) and (,12).
b) The line joining the points is not parallel to y-axis.
Equation of line:
Another points that could be lie on this line are (0.6,2) and (0.25,1.475)
c) The line joining the points is parallel to y-axis because points have the same x-coordinate.
Another points that could be lie on this line are (0.8,2) and (0.8,2.1)
