Answer:
Step-by-step explanation:
Red blood cells : Platelets = 680 : 40 = (680÷10) : (40÷10)
= 68 : 4 = (68÷4) : (4÷4)
= 17 : 1
Add the weight of both elephants then round to the nearest 100
Answer:
the slope is 4
Step-by-step explanation:
-you have to solve for y;keep y by itself on one side of the equation
-you start by subtracting 4x on both sides(to get rid of it on the left side of the equation). you end up with -y= -4x+6
-y must be positive when it is alone, so to make it a positive, you have to divide both sides of the equation by -1. you end up with y= 4x-6
-so now that we have y by itself and positive, we can identify the slope. (the slope will always be what is right next to x, in this case it is 4). so the slope is 4
Answer:
t = -24*log(2/3)
Step-by-step explanation:
The expression is:
V = 22,500*10^(-t/12)
Replacing with V = 10,000 and isolating t, we get:
10,000 = 22,500*10^(-t/12)
10,000/22,500 = 10^(-t/12)
4/9 = 10^(-t/12)
(2/3)² = 10^(-t/12)
2*log(2/3) = -t/12
-12*2*log(2/3) = t
t = -24*log(2/3)
