Answer:
False
Step-by-step explanation:
We find the volumes of the two cubes and compare them.
volume of cube = side^3
The volume of the 10-cm cube is:
V = (10 cm)^3 = 1000 cm^3
The volume of the 5-cm cube is:
V = (5 cm)^3 = 125 cm^3
1000/125 = 8
The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.
The statement is false.
B - 13
Okay, we know that Mark brought 1 notebook and the totally is 6.91 while one pencil costs $0.42.
x= number of pencils he brought.
we know the price of 1 notebook + the cost of pencils times the numbers of pencils he brought = total cost.
So the equation will be:
1.45 + 0.42x = 6.91 subtract 1.45 on both sides.
0.42x = 5.46 Then we solve for x by dividing both sides by 0.42
x= 13
So the number of pencils he brought is 13.
Answer:
Are not one-to-one functions
Step-by-step explanation:
As m(x) has symmetry at the line x=0, it is not one-to-one
As n(x) has symmetry at the line x=-6, it is not one-to-one
There is no answer, the equation is false.
