Answer:
B. 
Step-by-step explanation:
We are told that the smallest object visible with our eyes is similar to the width of a piece of hair, which is 
meters wide.
Using an optical microscope, we can see items up to 
meters wide.
To find the objects we can see with our eyes are how much larger than the objects we can see with an optical microscope, we can set an equation as:
Using the exponent rule of quotient 
we will get,
Therefore, the objects we can see with our eyes are times larger than the objects we can see with an optical microscope and option B is the correct choice.

Step-by-step explanation:
Answer:
5 hours because 395.1/79=5 hours
Step-by-step explanation:
1) y=(7/2)x-2.
Slope is the coefficient of x, that is 7/2
Intercept x is the value of x when y = 0 ==> 0=(7/2) X - 2==> 7/2x=2 &x=4/7
so intercept x, (4/7,0)
Intercept y is the value of y when x=0 ==> y= (7/2).(0) - 2 ==> y = 2
and so intercept y, (0,-2)
Now you will follow the same logic to find the are same questions
2) y= -6x + 3 ==>Slope= -6, Intercept x =1/2 & intercept y=3
3) y=-5 has a slope 0 (it doesn't exist). The graph is a line // to x-axis at y=-5
4)y=(6/5)x + 1:==>Slope= -5/6, Intercept x =-5/6 & intercept y=1
5) y=(1/4)x + 2 ==>Slope= 1/4, Intercept x =-8 & intercept y=2
6) x=5, this ligne is // to y axis at x=-5
Total possible outcomes = 36
Total possible outcomes with sum equal to 4 = 3
{1, 3} {2, 2}, (3, 1}
P(sum equal to 4) = 3/36 = 1/12
If you throw it 1000 times,
Number of times expected to have a sum of 4 = 1/12 x 1000 = 83 times
Answer: About 83 times
