S=0.6
Step by step explanation: subtract the greater number by the smaller number. Plug in the decimal after.
Answer:
Given the mass of the object = 15g
Given the volume of the object = 3 mL
Density = ?
Step-by-step explanation:
We have two values of an object that is mass of the object and volume of the object. Now we are required to find the Density of the object. In order to find the density of the object, we have to divide the given mass with the given volume. Below is the calculation of the density.
Density = Mass / Volume
Density = 15g / 3 mL
Density = 5 g/ml
Is there a picture to go with this problem?
We could factor the usual way but let's try Dr. Po Shen Loh's "new" method.
First step is to rewrite as a monic,
Now we need two numbers which add to 2/3m and multiply to -5/3m². If they add to 2/3m they average to 1/3m so they're 1/3m-u and 1/3m+u for some u. The product of those two is -5/3m² so we write:
So our equation
factors as
so has roots
The more standard factorization with the same result is
