Interest = Pin = principal * interest rate * number of years
Let interest rate be i, then
600*i*2+150*i*4=90
1200i+600i = 90
i=90/(1200+600)=90/1800=1/20=0.05 or 5%
He may be wrong. If he was wrong, this is the example.
0 < -10x
If we were to divide both sides by -10, even though the answer would be undefined or just end up as zero, it is just a common rule to always flip the sign whenever you divide or multiply by a negative.
Don't quote me on it, but I think I'm right.
Hope this helped!
It would be x + 5.75 because the child ticket is 5.75 less than the adult ticket so to solve how to get the adult ticket you do the opposite
Answer: 1296 cm³
Step-by-step explanation:
Since, the volume of a square pyramid is,
![V = \frac{a^2h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7Ba%5E2h%7D%7B3%7D)
Where a = side of the square base,
h = height of the pyramid,
By the given diagram,
a = 18 cm,
h = 12 cm,
Hence, the volume of the given pyramid,
![V = \frac{18^2\times 12}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B18%5E2%5Ctimes%2012%7D%7B3%7D)
![= \frac{324\times 12}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B324%5Ctimes%2012%7D%7B3%7D)
![=\frac{3888}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3888%7D%7B3%7D)
cube cm.
⇒ First option is correct.
