In the formula l=p+prt, what does l equal when p=500,r=20%, t=2
Juliette [100K]
Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

I=p+prt\\I=(500)+(500)(0.2)(2)\\I=500+200\\I=700

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.

Simply<br> tan 45°. sin 30° - cot 45°/sec 60°​
dusya [7]

If we want to write the given four numbers in another form, we can write it like this;

tan45=sin45/cos45=1

sin30=sin(\frac{\pi }{2}-60 )=cos60=\frac{1}{2}

cot45=cos45/sin45=1

sec60=1/cos60=\frac{1}{1/2} =2

Now let's rewrite the given expression and get the result.

(tan45.sin30)-(cot45/sec60)=(1.\frac{1}{2})-(\frac{1}{2} )=0
