In PEMDAS you do parentheses first
(32-20) equals 12
Now you divide
12/4 equals 3
The answer is 3
Answer:
1.2 miles
Step-by-step explanation:
Morning laps = 3.5 laps
Evening laps = 1 lap
Total miles jogged = 5.4 miles
Total laps made = (3. 5 + 1) = 4.5 miles
Number of miles per laps covered :
Total miles jogged / number f lapses hugged around pond.
= 5.4 miles / 4.5
= 1.2 miles
Therefore, number of miles per round around the pond is 1.2 miles
Answer:
The volume of the new can is ![V_2=160x^3\pi\ cm^3](https://tex.z-dn.net/?f=V_2%3D160x%5E3%5Cpi%5C%20cm%5E3)
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ----> the scale factor
In this problem
![z=x](https://tex.z-dn.net/?f=z%3Dx)
The volume of the original can is
![V_1=\pi r^{2}h](https://tex.z-dn.net/?f=V_1%3D%5Cpi%20r%5E%7B2%7Dh)
The volume of the new can is
![V_2=z^{3}V_1](https://tex.z-dn.net/?f=V_2%3Dz%5E%7B3%7DV_1)
![V_2=x^3(\pi r^{2}h)](https://tex.z-dn.net/?f=V_2%3Dx%5E3%28%5Cpi%20r%5E%7B2%7Dh%29)
we have
![r=4\ cm\\h=10\ cm](https://tex.z-dn.net/?f=r%3D4%5C%20cm%5C%5Ch%3D10%5C%20cm)
substitute
![V_2=x^3(\pi (4)^{2}10)](https://tex.z-dn.net/?f=V_2%3Dx%5E3%28%5Cpi%20%284%29%5E%7B2%7D10%29)
![V_2=160x^3\pi\ cm^3](https://tex.z-dn.net/?f=V_2%3D160x%5E3%5Cpi%5C%20cm%5E3)
The probability of picking two odd numbers would be 3 to 2 because you would have five cards left and you are left with 3 odds and 2 evens? I dont even know if I'm right. Sorry!
