product means multiply, at least means greater than or equal to
The product of a number and 5 is at least 45: 5n ≥ 45
If asked to solve, divide 5 from both sides: n ≥ 9
Answer: 5n ≥ 45
We have to calculate the volume of the right rectangular prism.
lenght=4 1/2 in=(4+1/2) in=9/2 in
width=5 in
height=3 3/4 in=(3+3/4) in=15/4 in
Volume (right rectangular prism = lenght x width x height.
volume=9/2 in * 5 in * 15/4 in=675/8 in³
we calculate the volume of this little cube.
volume=side³
volume=(1/4 in )³=1/64 in³
Now, we calculate the number of small cubes are needed to fit the right rectangular pris by the rule of three.
1 small cube----------------1/64 in³
x---------------------------------675/8 in³
x=(1 small cube * 675/8 in³) / 1/64 in³=5400 small cubes.
Answer: we need 5400 small cubes to fit the right rectangular prism.
x squared = 9 NOT x
x = square roots of 9 which is +3 or -3.
The slope of the line is three
81^1/3. We know that 81 is 3^4, meaning 3 x 3 x 3 x 3 is 81. So (3^4)^1/3 is 3^4/3, which is 3 * (cubed root of 3).
