Answer:
61.90
Step-by-step explanation:
The numbers of choices in each category are multiplied together. We assume the order of paint choices matters: using color 1 in area A and color 2 in area B is not the same as using color 2 in area A and color 1 in area B.
P(7,2)*4*3*2 = 42*4*3*2 = 1008 ways
_____
P(n, k) = n!/(n-k)!
P(7, 2) = 7*6 = 42
8m + 2q = 18.00
3m + q =. 7.50
8m + 2q = 18.00
-6m - 2q = -15.00
2m = 3.00
m = $1.50 each muffin
3(1.50) + q = 7.50
4.50 + q = 7.50
q= $3.00 for each quarter of milk
Answer:
cm.
Step-by-step explanation:
We have been given that the average human body cell is about
cm in diameter. The diameter of a plant cell is
cm.
To find the combined diameter of the body cell and plant cell, we will add both diameters.
First of all let us convert our given diameters in standard notation.
![5.1\times10^{-4}=0.00051](https://tex.z-dn.net/?f=5.1%5Ctimes10%5E%7B-4%7D%3D0.00051)
![8\times10^{-3}=0.008](https://tex.z-dn.net/?f=8%5Ctimes10%5E%7B-3%7D%3D0.008)
![\text{The combined diameter of body cell and plant cell}=0.00051+0.008](https://tex.z-dn.net/?f=%5Ctext%7BThe%20combined%20diameter%20of%20body%20cell%20and%20plant%20cell%7D%3D0.00051%2B0.008)
![\text{The combined diameter of body cell and plant cell}=0.00851](https://tex.z-dn.net/?f=%5Ctext%7BThe%20combined%20diameter%20of%20body%20cell%20and%20plant%20cell%7D%3D0.00851)
Let us convert our answer in scientific notation.
![\text{The combined diameter of body cell and plant cell}=8.51\times 10^{-3}](https://tex.z-dn.net/?f=%5Ctext%7BThe%20combined%20diameter%20of%20body%20cell%20and%20plant%20cell%7D%3D8.51%5Ctimes%2010%5E%7B-3%7D)
Therefore, the combined diameter of the body cell and plant cell is
cm.
