The correct answer is 1 7/15.
Answer: -3z+8
Step-by-step explanation: add -4z and z because they are like terms and then leave the 8 alone because it’s a term.
It's hard to have √2 points in a basketball game (or almost any game). The number of points scored is a discrete random variable, usually restricted to non-negative integers.
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:
