Answer:
25.81%
Step-by-step explanation:
32/124 were homeruns, to make it into a percentage, multiply it by 100%
32/124 × 100 = 25.81%
Answer:
11
Step-by-step explanation:
We evaluate W(x)=3•3^x+3 + 2 at x = -2 by substituting -2 for each instance of x:
But first note that we must enclose x + 3 inside parentheses:
W(x)=3•3^(x+3) + 2.
Substituting -2 for x, we get:
W(-2)=3•3^(-2+3) + 2, or
W(-2)=3•3^(1) + 2, or
W(-2)=9 + 2 = 11
27.
18 divided by 2 = 9
40 divided by 2 = 20
20 x 3 = 60 min = 1 hour
9 x 3 = 27.
so 27 problems finished in 1 hour.
The number of bacteria at any time t where t is number of hours is given by the equation,
At = Ao(1/2)^t/4
where Ao is the original number of bacteria. Substituting the known values from the equation,
1500 = (75000)(0.5)^t/4
The value of t from the equation is equal to 22.57 hours.
