Answer:
38
Step-by-step explanation:
30 = X-8
+8 +8
38=x
After clarification we see the respective diameters are
![A = 2.3 \times 10^{-a}](https://tex.z-dn.net/?f=A%20%3D%202.3%20%5Ctimes%2010%5E%7B-a%7D)
![B = 2.3 \times 10^{-b}](https://tex.z-dn.net/?f=B%20%3D%202.3%20%5Ctimes%2010%5E%7B-b%7D)
We're asked about the ratio
![A:B = 2.3 \times 10^{-a} : 2.3 \times 10^{-b} = 10^{-a} : 10^{-b} = 10^b : 10^a = 10^{b-a} : 1](https://tex.z-dn.net/?f=A%3AB%20%3D%20%202.3%20%5Ctimes%2010%5E%7B-a%7D%20%3A%20%202.3%20%5Ctimes%2010%5E%7B-b%7D%20%3D%2010%5E%7B-a%7D%20%3A%2010%5E%7B-b%7D%20%3D%2010%5Eb%20%3A%2010%5Ea%20%3D%2010%5E%7Bb-a%7D%20%3A%201)
Now we can go through the choices.
A. If a = 4 and b = 6, then cell a is 100 times greater than cell b.
![A:B=10^{6-4}:1 = 100:1](https://tex.z-dn.net/?f=%20A%3AB%3D10%5E%7B6-4%7D%3A1%20%3D%20100%3A1)
It would be more proper to say the diameter of cell A is 100 times the diameter of cell B, but yes, this is TRUE.
B. If a = 4 and b = 6, then cell b is 100 times greater than cell a.
FALSE. 10 to the minus 4 is 100 times bigger than 10 to the minus 6, so a is bigger.
C. If a = 4 and b = 6, then cell a is 2 times greater than cell b.
FALSE. We already calculated its 100 times bigger.
D. If a = 4 and b = 6, then cell b is 2 times greater than cell a.
FALSE.
Answer:
a) f(x) = x^2
b) f(x) = x
c) any pair of numbers
Step-by-step explanation:
Answer:
216 cubic inches
Step-by-step explanation:
(9)(3)(3)=81
(3)(3)(9)=81
(3)(3)(6)=54
81+81+54=216
So, it's 216 cubic inches in volume.
Answer:
s = 22t or
, when s is students and t is teachers.
Step-by-step explanation:
I. Given t = teacher, s = student
When 1 teacher per 22 students so...
s = 22t
If there're 10 teachers
s = 22(10)
= 220 or ![\frac{t}{s} = \frac{1}{22}](https://tex.z-dn.net/?f=%5Cfrac%7Bt%7D%7Bs%7D%20%3D%20%5Cfrac%7B1%7D%7B22%7D)
Hope that help :)
