Answer: x=2
Step-by-step explanation:
first subtract 3x from both sides
then your equation will be 8x-7=9 then you will add 7 to both sides getting 8x=16 then divide both sides by 8 and x=2
Answer: you could do store A is $8 per hour, and thirteen $13 per day, store B can be $3 per hour, $18 per day
I'm not too confedent but I'm still happy to help!
Answer:
exactly
Step-by-step explanation:
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:

1.00 no problem, I tired thank you
