Answer:
1 hour
Step-by-step explanation:
if he spends 2 hours on his math, then half of that is 1 hour. However, if it's saying that be spend 2 hours on math and english <em>combined</em>, then the answer would only be 30 minutes. Hope this helps (:
Solving the system of equations, it is found that a viable time that the trains are side by side is given by:
B. 15 sec
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the equations are:
They will be side by side when:
It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:
Time is a non-negative measure, hence option B is correct.

P(Getting # less than 3) = 2/6
P(Getting tails) = 1/2
P(Less than 3 and tails) = 1/2*2/6 = 1/6
Answer: 1/6
Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.
