183 x 194 = 35,502
you could use a calculator or put it into the overlap form
To find r, you need to isolate it. pi*r^2*60=18,840. divide 18,840 by 60, then pi, it comes out at 100. Now find the square root to get 10
r=10
Answer:
x = log 7
Step-by-step explanation:
10^x=7
Take the log base 10 on each side
log10 (10^x)=log10 (7)
We dont need to write the 10, it is implied
log(10^x)=log (7)
The exponent goes out front since log a^b = b log a
x log 10 = log 7
log 10 = 1 since the base is 10 log10(10) =1
x = log 7
Answer:
Step-by-step explanation:
11) 4x+2=5x-10 => 4x-5x=-10-2 => -x=-12 => x=12
12)25x=24x+4 => x=4
13)20x=21x-5 => -x=-5 => x=5
14)20x+10x=180 => 30x =180 =>x=6
