Answer:
The correct answer is if you want no roots in the denominator, the correct answer is
* ![\sqrt[3]{2y^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E%7B2%7D%20%7D)
Step-by-step explanation:
The mistake is that you can't take a cube root of a square at step 3 when
is taken out.
How many booths and tables are there altogether?
Answer:
If we assume a temperature of 20ºc and the blood interfacial surface tension is similar to water interfacial surface tension, the diameter of the capillary tube should be 0.933mm.
Step-by-step explanation:
The Jurin law describes the height a fluid can reach in a capillary tube. This law can be written as:

where γ is the interfacial surface tension, θ is the contact angle with the fluid, ρ is the fluid density, g is the gravity acceleration and r is the tube radius.
If we assume that the interfacial surface tension of blood and water are almost the same, γ=0,0728 N/m at 20ºc. Therefore the diameter of the tube will be:

Answer:
x = 10
y = 14
Step-by-step explanation:
Here, we want to get the values of x and y
Since all sides are equal, the internal angle is 60 degrees for each internal angle
Since AC = 14
Then y is also 14 since what we have is an equilateral triangle
Secondly ;
6x = 60
x = 60/6
x = 10
