Let s = #small notebooks
Let L = #large notebooks
We Can set up two equations from the info given.
s + L = 6 bought 6 notebooks total
8s + 10L = 56 spent $56
Solve equation 1 for one variable.
L = 6-s
Plug 6-s in equation 2 in place of L
and solve for s
8s + 10(6-s) = 56
8s + 60 - 10s = 56
-2s + 60 = 56
-2s = -4
s = (-4)/(-2)
s = 2
We know s+L = 6 and s=2
2+L = 6
L = 4

Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
Answer:
s≤4 cm.
Step-by-step explanation:
Let s be side of cube.
As we know that the volume of cube=side×side×side
Here, it is given that the volume of cube = 64 cubic centimeters.
or we can write
side×side×side=64 cubic centimeters
Taking cube root both sides
side= 4 cm
In order to build a cube with a minimum of 64 cubic centimeters,
we can take the value of s≤4 cm.
Hence, the reasonable range for s, the side length is s≤4 cm.
