The quotient estimated value of 394.6/9 is 43.84
What is quotient?A quotient is the number which is generated when we perform division operations on two numbers. Basically, it is the result of the division method. There are four main terminologies used in the arithmetic division such as divisor, dividend, quotient and remainder. For example, 15/3= 5 .The number that is being divided ( 15) is called the dividend, and the number that it is being divided by (3) is called the divisor. The result of the division(5) is the quotient.
Therefore the quotient of 394.6/9= 43.84

In an election for a corporation seat, there were two candidates. A total of 9,791 votes were polled. 116 votes were declared invalid. The successul candidate got 5 votes for every 4 votes his opponent had. By margin did the successful candidate win?
Margin did the successful candidate win is 5375 - 4300 = 1075.
Given:
In an election for a corporation seat, there were two candidates. A total of 9,791 votes were polled.
116 votes were declared invalid. The successful candidate got 5 votes for every 4 votes his opponent had.
Number of valid votes = 9791 - 116 = 9675.
Let the number of votes of successful candidate = 5x
Let the number of votes of opponent = 4x
5x + 4x = 9675
9x = 9675
divide by 9 on both sides
x = 9675/9
x = 1075
Hence the votes for successful candidate = 5*1075 = 5375.
votes for opponent = 4*1075 = 4300.
Margin by which the successful candidate wins = 5375 - 4300 = 1075.

Step 2 of 2 : Determine the missing coordinate in the ordered pair (?,5) so that it will satisfy the given equation.
The equation of line s is y= – 4x– 5/3 . Line t includes the point ( – 3,3) and is parallel to line s. What is the equation of line t?
The equation of the parallel line t is y = -4x - 9
How to determine the line equation?The equation of line s given as
y = -4x - 5/3
Also, from the question
The point on line t is given as
Point = (-3, 3)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = -4
This means that the slope of y = -4x - 5/3 is -4
The slopes of parallel lines are equal
This means that the slope of the line t is -4
The equation of the parallel line is then calculated as
y = m(x - x₁) +y₁
Where
m = -4
(x₁, y₁) = (-3, 3)
Substitute the known values in the above equation
y = -4(x + 3) + 3
Evaluate
y = -4x - 12 + 3
Evaluate the sum
y = -4x - 9
Hence, the parallel line has an equation of y = -4x - 9

The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=26(4)−x5, find the revenue if 15 units are sold. Round to two decimal places.
If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.
How to calculate the amount of revenue at p(15)?From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):
R(x) = x × P(x)
Where:
x represents the number of units sold.p(x) represents the unit price.Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:
Revenue, R(x) = x × 26(4)^{-x/5}
Substituting the given parameters into the formula, we have;
Revenue, R(x) = 15 × 26(4)^{-15/5}
Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³
Revenue, R(x) = 15 × 26(0.015625) or 390/64
Revenue, R(x) = 6.09375 ≈ $6.09.

Calculate (A) amount to be credited and (B) balance outstanding: (Round your answers to the nearest cent.) Invoice: $3,000; Terms 2/10, n/30 Invoice date: July 5 Payment amount $600 Date paid: July 14
The amount to be credited, based on the invoice amount and the payment, is $612.24. The balance outstanding is $2, 387.76
How to find the balance outstanding?Credit terms of 2/10, n/30 mean that if a buyer pays their payables in 10 days, they get a 2% discount. If they don't, then they'd have to pay the full thing in 30 days.
The days till the partial payment was made was:
= July 14 - July 5
= 9 days
The discount of 2% would apply on the payment of $600 so the amount to be credited is:
= 600 / (1 - 2%)
= $612.24
The balance would then be:
= Invoice amount - credited amount
= 3, 000 - 612.24
= $2, 387.76

Answer:
Value of x = 7° & y = 45°
Step-by-step explanation:
According to the question m || n.
For x:
[tex] \rm \implies (7x + 13) \degree = (6x + 20) \degree \\ \\ \rm \implies 7x - 6x = 20 \degree - 13\degree \\ \\ \rm \implies x = 7 \degree[/tex]
For y:
[tex] \rm \implies (3y - 17)\degree + (6x + 20) \degree = 180\degree \\ \\ \rm \implies (3y - 17)\degree + (6 \times 7 + 20)\degree = 180\degree \\ \\ \rm \implies (3y - 17)\degree + (42 + 20)\degree = 180\degree \\ \\ \rm \implies 3y - 17\degree + 62\degree = 180\degree \\ \\ \rm \implies 3y + 45\degree = 180\degree \\ \\ \rm \implies 3y = 180\degree - 45\degree \\ \\ \rm \implies 3y = 145\degree\\ \\ \rm \implies y = \bigg( \frac{145}{3} \bigg) ^\degree \\ \\ \rm \implies y = 45\degree[/tex]

Using trigonometric ratios, tan a + cot a = (cos a + sin a) / sin a * cos a
Trigonometric RatioThe six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trigonometric ratios are evaluated with respect to sides and angles.
In the question given, the trig ratio is
tan a + cot a
We can simplify this as
tan a = sin a / cos a
cot a = 1 / tan a = 1 / sin a / cos a = cos a / sin a

A firm manufactured 1000 Tv sets during its first year.the total firms production during the 10 year of operationis 29035 sets .
For each the level of output for 15th year using per year constant increase in production .
Answer:
6922 TV sets
Step-by-step explanation:
You want the production in the 15th year if production in the first year is 1000 and it increases yearly by a constant amount. The total production in the first 10 years is 29035.
Arithmetic seriesAn arithmetic series is one that has a constant difference from one term to the next. If a1 is the first term of the series, and d is the common difference between terms, the n-th term is ...
an = a1 +d(n -1)
And the sum of n terms is ...
Sn = (2a1 +d(n-1))(n/2)
ApplicationTo find the 15th term, we can make use of the given values to find the common difference, then use the formula for the n-th term.
S10 = (2(1000) +d(10 -1))(10/2) . . . . . sum formula with a1=1000
29035 = 10000 +45d . . . . . . . . . . . simplified
d = (29035 -10000)/45 = 423 . . . . the increase in production each year
Production in the 15th year is ...
a15 = 1000 +423(15 -1) = 1000 + 5922 = 6922
The output in the 15th year was 6922 TV sets.
