<u>Given</u>:
Two cylinders are similar. The volume of one is 64 cm³ and the volume of the other is 729 cm³.
We need to determine the scale factor between them.
<u>Scale factor:</u>
Since, it is given that the volume of two cylinders, we need to take cube root.
Thus, we have;
![Scale \ factor=64:729](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D64%3A729)
Taking cube root, we get;
![Scale \ factor=\sqrt[3]{64} :\sqrt[3]{729}](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D%5Csqrt%5B3%5D%7B64%7D%20%3A%5Csqrt%5B3%5D%7B729%7D)
Simplifying, we have;
![Scale \ factor=4:9](https://tex.z-dn.net/?f=Scale%20%5C%20%20factor%3D4%3A9)
Thus, the scale factor between the two cylinders is 4 : 9
Hello! Haley has 7 pens, with 3 more of them being blue than black. If you do some mental math, you know that 5 is 3 more than 2 and 2 + 5 is 7. So Haley has 5 blue pens and 2 black pens.

Answer:
18$
Step-by-step explanation:
If you divide 12 by 2 then you will get 6 so 6 times 3=18.
sorry if I'm wrong.
Step-by-step explanation:
5c-2c is 3c
3-4 is -1
so the expression is 3c-1
