<h3>Further explanation</h3>

<u>The Problem:</u>

  • Subtract 4 from \frac{1}{6} of 42.
  • Write an expression to match and then evaluate.

<u>The Process:</u>

Here are some early expressions that need attention.  

  • 1 sixth is \boxed{\frac{1}{6}}
  • 1 sixth of 42 is \boxed{\frac{1}{6} \times 42} or \boxed{\frac{1}{6}} multiply 42.

Let us write an expression to match for subtract 4 from \frac{1}{6} of 42.

\boxed{\boxed{ \ \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }}

And now we evaluate the expression.

\boxed{ \ = \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }

We cross out 6 and 42 because they both can be divided.

\boxed{ \ = 7 - 4 \ }

Thus the answer is \boxed{\boxed{ \ 3 \ }}

<u>Notes:</u>

  • Recall that \boxed{\frac{42}{6} \rightarrow 42 \div 6 = 7}
  • Since \boxed{ \ \boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 42 \ }, then one of six parts of 42 or \boxed{\frac{1}{6} \ of \ 42 \ equal \ to \ 7}
  • Since \boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1} = 7, then subtract 4 from 7 equal to 3, that is \boxed{1}\boxed{1}\boxed{1} = 3.

Rationalize the denominator of the fraction: √5/√8 - √3
Lana71 [14]

Answer:

Step-by-step explanation:

Remark

The editor must have brackets put around the denominator when there are 2 terms.

That means I think the question is (√5) / (√8 - √3). If this is incorrect, leave a note.

To rationalize the denominator, you must multiply numerator and denominator by the conjugate  (√8 + √3).

Solution

√5 *  (√8 - √3) /  ( (√8 - √3) *  (√8 + √3)  )  

I don't think there is any point in removing the brackets in the numerator. Just leave it.

The denominator is a different matter.

denominator = ( (√8 - √3) *  (√8 + √3)  )

√8 * √8 = 8

√8 * √3 = √24

- √3 * √8 = - √24

-√3 * √3 = - 3

Take a close look at the 2 middle terms. They cancel out because one of them is plus and the other minus.

What you are left with is 8 - 3 = 5

So the final answer is

√5 *  (√8 - √3)

ZA and ZB are complementary angles. If mZA = (7x + 23)° and
Marat540 [252]

Answer:

ZB= 39°

Step-by-step explanation:

complementary angles are angles that add up to equal 90

equation:  7x + 23 + 5x + 19 = 90

add like terms: 12x + 42 = 90

subtract 42 from both sides: 12x = 48

divide both sides by 12: x = 4

plug in the value of x to the equation for ZB: 5(4) + 19

simplify: ZB= 39°

Determine whether the data set is a population or a sample. Explain your reasoning. The salary of each teacher in a school. Choo
SVETLANKA909090 [29]

Answer:

D. ​Population, because it is a collection of salaries for all teachers in the school.

Step-by-step explanation:

In research, population refers to a complete set of subjects that share a characteristic and that the researcher is interested in. On the other hand, a sample is a subset of a population and it's usually the one the researcher takes to make a study with.

In this example, we have "The salary of each teacher in a school" since we are taking ALL the teachers of this school, this would be a population. If we were working with the salary of only a portion of the teachers of said school, it would be a sample.

Thus, the right answer is  D. ​Population, because it is a collection of salaries for all teachers in the school.
