Answer:
D
Step-by-step explanation:
Squaring 121 will still be a real number, a rational number, and an integer. Therefore, it is not an irrational number.
There is a rule:
One input(x-value) can only have one output(y-value) in order to be a function.
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
The 1st option is not a function because the inputs 9 and 10 have more than one output.
The 2nd option is not a function because the input 3 has more than one output.
The 3rd option is a function because each input only has one output.
The 4th option is not a function because the input 5 has more than one output.
Answer: No, she does not have enough.
Step-by-step explanation:
1. You have the following information given in the problem above:
- The measures of the three pieces are: 32 centimeters, 41.19 centimeters and 57.8 centimeters long.
- She need 200 centimeters of ribbon for the box.
2. Therefore, you must add the measures given in the problem to know if Marie has enough ribbon to decorate the gift box. Then:

3. As you can see:
130.99 cm<200 cm
Therefore, she does not have enough ribbon.
About 3.8 hours, if asking for a whole number round to 4
Surface area of a ball:
S=4πr^2=4*π*5^2=100π
Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π
The approximate surface-area-to-volume ratio would be 1:1,5
