Answer:
The fence will cost $333.64
Step-by-step explanation:
In order to calculate how much it'll cost to build the fence around his garden we first need to know the length of material he'll need to buy. To do that we must find the length of the circle that surrounds the garden and then multiply by the price of each foot. The length of the circle is given by:
length = 2*pi*r
length = 2*pi*15
length = 30*pi
length = 94.25 feet
The cost of the fence, is:
cost = length*(cost per foot) = 94.25*3.54
cost = 333.64
The fence will cost $333.64
Answer:
−10x+3
Step-by-step explanation:
<span>(7 x 10^−12)(4 x 10^5)
= (7x4) x 10^-7
= 28 x 10^-7
= 2.8 x 10^-6</span>

Answer:
64
Step-by-step explanation:
<u>ASSUMING WE STARTED WITH ONE BACTERIA</u>
there are 3 20 minute marks in an hour.
3 x 2 = 6
So are going to do the following
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
...
So in two hours a bacteria that increases two times every twenty minutes would multiply into sixtyfour bacteria in 2 hours.
