Braddock should prepare 6 test tubes.
Given:
cylinder:
height = 40mm
radius = 12 mm
pi = 3.14
volume of test tube = 3014 mm³
We need to get the volume of the cylinder to know how much saline solution it holds.
Volume = π r² h
= 3.14 * (12mm)² * 40mm
= 3.14 * 144mm² * 40mm
Volume = 18,086.40 mm³
To get the number of test tubes used: we need to divide the volume of the cylinder by the volume of the test tube.
18,086.40mm³ / 3014mm³ = 6 test tubes.
Answer:
Newtons 2nd law of motion
Step-by-step explanation:
Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.
Answer:
10x - 13.
Step-by-step explanation:
−3(6x+ 7) + 4(7x + 2)
= -18x - 21 + 28x + 8
= 10x - 13.
The solution is 3x^2
For solve the equation need to use the limit. I don’t know if you already study it
