The mass of substances left in a sample
professor190 [17]

This question tests one's knowledge of states of matter. Kim would have to classify the water as gaseous matter in this case.

<h3>Why should Kim classify the water as gaseous?</h3>

Remember, she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

Matter can exist in various states. They are:

  • Solids;
  • Liquids;
  • Gaseous;
  • Plasma; and
  • Bose-Einstein condensate. (which is Man-made).

Rewrite -4/15 as an equivalent fraction
timofeeve [1]

(\frac{-4}{5} ) in the form of Equivalent Fraction can be written as \frac{-4x}{15x}, where "x" is any integer.

As per the question statement, we are provided with a fraction, (\frac{-4}{5} ).

We are required to rewrite the above mentioned fraction in the form of a general Equivalent Fraction.

To solve this question, we need to know what an equivalent fraction is.

Equivalent fractions are those fractions that have different numerators and denominators but are equal to the same value, when simplified.

For example, (\frac{1}{2}, \frac{2}{4}, \frac{3}{6}, \frac{4}{8}) all equate to \frac{1}{2} when simplified.

Now, for this case, equivalent fractions of (\frac{-4}{5} ) are (\frac{-8}{30}, \frac{-12}{45}, \frac{-16}{60},...), where

\frac{-8}{30}=\frac{(-4)*2}{15*2}\\\frac{-12}{45}=\frac{(-4)*3}{15*3}\\ \frac{-16}{60}=\frac{(-4)*4}{15*4}

i.e., the equivalent fractions of (\frac{-4}{5} ) are in the form of  \frac{-4x}{15x}, where "x" can be any integer, (...-6, -5, -4, -3, -2, -1, 2, 3, 4, 5, 6...)

Solve T=C(5+ AB) for B.
Vaselesa [24]

Answer:

b =  \frac{t - 5}{a}

Step-by-step explanation:

t = c(5 + ab)

Simplify:

t = 5c + abc

Move 5c to the other side:

t - 5c = abc

Divide bother sides with AC:

\frac{t - 5c}{ac}  =  \frac{abc}{ac}

Simplify:

\frac{t - 5}{a}  = b
