Bracket OfDivision Multiplication Addition SubtractionIn the numerator:
the addition would be done first: 3² + 1 = 9 + 1 = 10
Then the subtraction would be done next = 14 - 10 = 4
Now determine the square of the term in the bracket : 4²= 16
In the denominator:
The multiplication would be solved first: 3 x 1/4 = 3/4
The next step is to solve the division : 1 ÷ 3/4 = 1 x 4/3 = 4/3

peruvian cafe bought ad time on radio station wkoi. during the first four weeks, 4,000 different people heard the spot six times, while 2,000 heard it only three times during the same period. what is the average frequency?
The average frequency of people hearing the spot on the radio station is equal to 5.
Average frequency can be defined as the average number of times an individual is exposed to an Advertising schedule.
Average frequency can be calculated by using the formula;
average frequency = total / n
As 4000 people heard the spot 6 times and 2000 people heard it three times; therefore
n = 4000 + 2000 = 6000
total = number × frequency = (6 × 4000) + (3 × 2000) = 24000 + 6000 = 30,000
Substituting these values in the equation;
average frequency = 30,000 / 6000
average frequency = 5
Hence the average frequency of people hearing the spot on the radio station wkoi is calculated to be 5.

The values of the angles m∠1 and m∠3 is equal to 73°.
A transversal may be defined as a line which cuts a pair of parallel lines and forms several angles. When transversal cuts parallel lines the alternate interior angles are equal as well as the corresponding angles are equal. Also, the pair of vertically opposite angles are equal. From the figure attached. ∠4 = ∠8 as they are corresponding angles. So, m∠8 = m∠4 = 107°. Now, we know that ∠1 and ∠4 formed a pair of linear angles and the sum of the measures of the linear angles is 180°. So,
m∠1 + m∠4 = 180°
We know, m∠4 = 107°
m∠1 = 180° - 107°
m∠1 = 73°
Now, ∠1 and ∠3 are vertically opposite angles, so they are equal as the parallel lines are cut by transversal. Therefore, m∠1 = m∠3
=> m∠1 = 73°
=> m∠3 = 73°

The value of the part of 20 that is 46% is 9.2.
How to determine the percentage of a number?Percentage is simply a number or ratio expressed as a fraction of 100.
It is expressed as;
Percentage = ( Part / Whole ) × 100%
Given the data in the question;
Percentage = 46%Whole = 20Part = ?Plug the given values into the above formula and solve for the part.
Percentage = ( Part / Whole ) × 100%
46% = ( Part / 20) × 100%
46/100 = ( Part / 20 ) × 100/100
46/100 = ( Part / 20 ) × 1
46/100 = Part / 20
Cross multiply
46 × 20 = Part × 100
920 = Part × 100
Part = 920/100
Part = 9.2
