0.00356 is the standard form
Answer:
a=35°, b=55°, c=110°
Step-by-step explanation:
reason for a and b is that when 2 lines intersect, the opposite angles are equal.
well for c angles on a straight line add upto 180.
Answer:
B
Step-by-step explanation:
Answer:
The equation is 
at a rate of -23%.
Step-by-step explanation:
Decay can be represented by the equation 
. We can find the rate at which it decays by using t=3 hours and A=3000. This means 
in this context.
After substituting, we divided by 6000 to each side to get 0.5 on the left. Now to solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know 
so we were able to cancel it out and divide both sides by 3.
We solve with a calculator 
We change -0.23 into a percent by multiplying by 100 to get -23% as the rate.
The equation is
5% of the kids are in health. I got this from simplifying 3/60 which is 1/20
After that, i set up this equation: 1/20 times x/100
I would then divide 20 and 100 to get 5 and that’s basically what I did
