Repeating decimals are rational
Answer: 45 in squared
Step-by-step explanation:
To find area of a triangle, you have to find the area of a square, and divide it in half. A 90 inch high square with a 1 inch base would be 90 inches, however, if you are solving for a triangle, it would be 45 inches
Let r be the decay rate (time in minutes) 17 = 20 e^(5r) 0.85 = e^(5r) ln 0.85 = 5r similarly, ln 0.5 = hr ... where h is the half-life, so dividing the 2 equations, ln 0.85 / ln 0.50 = 5r / hr = 5/h h = 5 ln 0.50 / ln 0.85 h = 21.3 min b) 1/20 = 0.05, so ln 0.85 = 5r ln 0.05 = tr t = 5 ln 0.05 / ln 0.85 t = 92.2 min
The answer is the first choice, 3(w-4)=5.
3 times = 3
a number minus four = (w-4)
is five = 5
I hope this helps.
