-1\le\sin\theta\le1\implies(\csc\theta\le-1)\cup(\csc\theta\ge1)

which means \csc\theta=0 has no solution, and we can omit that factor.

This leaves us with

2\cos\theta-1=0\implies\cos\theta=\dfrac12

which occurs for \theta=\pm\dfrac\pi3+2n\pi.

when full the gas tank of a car holds 15 gallons. it now contains 12 gallons. what percent represents how full the tank is?
Masteriza [31]

Hello!

to find the percent of a whole, use this equation here:

(remaining) / (total) = X

X * 100 = %

in this case:

12 / 15 = 0.8

0.8 * 100 = 80

your answer is 80%

I hope this helps, and have a nice day!

mafiozo [28]

Answer:

She will thin she has 96 extra dollars.

Step-by-step explanation:

Since she recorded it as a credit she thinks that she added that to her account, and let´s say that in her account she had $100, now she has to pay $48, so in reality she has $100-$48=52, so she actually has $52 in her account, but in her checkbook she has that she had $100 and added$48, so she will have: $100+$48=$148, that a $96 deficit from her actual account to her checkbook.
