Twenty added to the sum of a number and six is twenty-seven
Answers
-- Call the number 'N'.
-- The sum of the number and six is (N + 6).
-- Twenty added to it is 20 + (N + 6)
-- That whole thing is twenty-seven
20 + (N + 6) = 27
Subtract 20 from each side: (N + 6) = 7
Subtract 6 from each side: N = 1

What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A business center is about 3 3/4 times as tall as a monument.
Then, the conversion factor= 3 3/4 = 15/4 times
The monument is 444 feet tall.
Now, the business center is 3 3/4 times as tall as a monument.
So, the height of business center
= 444 x 3 3/4
= 444 x 15/4
= 111 x 15
= 16,665 feet
Hence, the businesscenter is 16,665 feet.

Answer: 1,665
To find the product rewrite 444 and 3 3/4 as fractions: 444 x 3 3/4= 444/1 x 15/4. Multiply 444/1 x 15/4= 6,660/4. Divide 6,660 x 4= 1,665. So the business man is about 6,660/4 or 1,665 feet tall.

==>t=4 or t=-7/2
Final answer:
The solution to the equation -2t^2 + t + 28 = 0 is found by applying the quadratic formula. Upon simplification, the possible values for 't' are 4 and -3.5.
Explanation:
The subject of the question is Mathematics and it is related to the concept of Quadratic Equations. Then, we are given the quadratic equation -2t^2 + t + 28 = 0 and asked to solve for 't'. We can solve quadratic equations using quadratic formula which is given by -b ± √(b^2 - 4ac) / 2a.
- First, identify the coefficients. In this equation the coefficients are: a=-2, b=1, and c=28
- Then Substitute these coefficients into the quadratic formula: t = [ -b ± sqrt (b^2 - 4ac) ] / 2a
- This gives: t = [ -1 ± sqrt ((1)^2 - 4*(-2)*28) ] / 2*(-2)
- Simplifying further gives: t = [ -1 ± sqrt (1 + 224)] / -4
- So, the possible values of t are: t = [ -1 ± sqrt ( 225 ) ] / -4
- Finally, we get the solutions: t = [ -1 ± 15 ] / -4
- This simplifies to t = 4 or t = -3.5

Let w represent employee's weekly sales and be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.

Conditional frequencies offer more specific information to analyse certain data set.
Step-by-step explanation:
A conditional frequency is a type of relative frequency which involves a condition to be defined.
For example, the conditional frequency of having a house given that the person is female. Notice that this example shows the condition "being female", so the conditional frequency would be all females who own a house.
On the other hand, the relative frequency is just a ratio between the frequency of the data and the total number of data. It's doesn't includes a condition to be defined, that's the difference.
Therefore, conditional frequencies offer more specific information to analyse certain data set.
