Answer:

RS 146189.8

Step-by-step explanation:

let the price before tax be p

hence the final amount paid (i.e the actual bill)

= price before tax + tax

= p + (0.13% of p)   (convert percentage into fraction)

= p + [ (0.13/100) x  p] ---------------(eq 1)

we are given that the tax (i.e VAT) = 189.80

hence,

[ (0.13/100) x  p] = 189.8

0.13p = (100)(189.8)

p = (100)(189.8) / 0.13

p = 146000

hence our eq 1 above becomes:

p + [ (0.13/100) x  p]

= 146000 + 189.8

= 146189.8

Answer:

C

Step-by-step explanation:

We are given that:

[tex]a(x+b)<c[/tex]

Where a < 0.

To solve for x, we can divide both sides by a.

Since a < 0, a is negative. Hence, we must flip the inequality sign. This yields:

[tex]\displaystyle x + b > \frac{c}{a}[/tex]

Subtract b from both sides. Hence:

[tex]\displaystyle x>\frac{c}{a}-b[/tex]

In conclusion, our answer is C.

Answer:

$13,400

Step-by-step explanation:

We will first have to take account of the commuting cost, years at school, and total cost of tuition and books

It would cost $5,500 per year, she is studying at the school for 2 years, we will multiply 5,500 by 2

$5,500 * 2

= $11,000

The cost of commuting per month will be multiplied by 12 to represent a year and another 2 for two years

$100 * 12 * 2

= $2400

We all these together for the total cost of her education

$11,000 + $2,400

= $13,400

Answer:

If I'm understanding the question right it's -.05

Step-by-step explanation:

(2x - 3) = 2

There is no more simplifying to be done in the parentheses.

2x - 3 = 2

Subtract 3 on each side to get the x value by itself.

2x = -1

Divide each side by 2 so the x is by itself.

x = -.05

And that's it, hope I helped :)

Answer:

We conclude that the relation is a function but it is not a linear function.

Step-by-step explanation:

The given table represents a function because each input or x-value is related to exactly one output or y-value.

In other words, there is no repetition of 'x' values. This indicates that the given relation in the table represents a function.

In order to check whether the function is linear or not linear​, we need to check how x and y values change.

The table indicated that x increases by 2, now we need to determine whether the y-values increases at a constant rate or not. For this, we need to find the first difference between y-values.

-3 - (-8) = 5

3 - (-3) = 6

7 - 3 = 4

As the first difference between the consecutive y-values is not constant, meaning that y-values do not increase at a constant rate as x-values increase by 2.

Thus, it is not a linear function,

Therefore, we conclude that the relation is a function but it is not a linear function.

Answer:

[tex]\theta=251.6^\circ[/tex]

Step-by-step explanation:

Complex Numbers

They are expressed as the sum of a real part and an imaginary part:

[tex]Z = a+b\mathbf{ i}[/tex]

Complex numbers can also be expressed in polar form:

[tex]Z = r(\cos\theta+\sin\theta \mathbf{ i}) = r. cis(\theta)[/tex]

Where r is the modulus of the complex number and θ is the argument.

The argument can be calculated by:

[tex]\displaystyle \tan\theta=\frac{b}{a}[/tex]

The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.

The complex number is given as:

[tex]Z = -3 -9\mathbf{ i}[/tex]

Here: a=-3, b=-9

Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).

[tex]\displaystyle \tan\theta=\frac{-9}{-3}[/tex]

[tex]\displaystyle \tan\theta=3[/tex]

[tex]\theta=\arctan(3)[/tex]

The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus

[tex]\mathbf{\theta=251.6^\circ}[/tex]

Answer:

The series has 7 terms

[tex]\displaystyle S_7=\frac{4372}{243}[/tex]

Step-by-step explanation:

Geometric Series

In the geometric series, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the series:

-12, -4, -4/3, ..., -4/243

We can find the common ratio by dividing one term by the previous term:

[tex]\displaystyle r=\frac{-4}{-12}[/tex]

Simplifying:

[tex]\displaystyle r=\frac{1}{3}[/tex]

Sum of terms: Given a geometric series with first term a1 and common ratio r, the sum of n terms is:

[tex]\displaystyle S_n=a_1\frac{1-r^n}{1-r}[/tex]

We need to find how many terms the series has. Using the explicit formula of a geometric series:

[tex]a_n=a_1\cdot r^{n-1}[/tex]

The last term is an=-4/243 and the first term is a1=-12. Solving for n:

[tex]\displaystyle n= \frac{\log(a_n/a_1)}{\log r}+1[/tex]

[tex]\displaystyle \frac{\log(-4/243/-12)}{\log 1/3}+1[/tex]

[tex]\displaystyle \frac{\log(1/729)}{\log 1/3}+1[/tex]

n=7

The series has 7 terms

Thus, the sum of the 7 terms of the series is:

[tex]\displaystyle S_7=-12\frac{1-(1/3)^7}{1-(1/3)}[/tex]

[tex]\mathbf{\displaystyle S_7=\frac{4372}{243}}[/tex]

Answer:

2/5

Step-by-step explanation:

The answer is common sense.

The probability that no two consecutive flips have the same result is [tex]\frac{1}{16}[/tex].

If a coin is flipped then there are two possible outcomes Head(H) and Tail (T).

So each flip can have 2 possible outcomes. It means 5 flips have [tex]2^5=32[/tex] possible outcomes.

Among these 32 outcomes only 2 outcomes : HTHTH and THTHT have "no two consecutive flips have the same result".

So the probability that no two consecutive flips have the same result is = [tex]\frac{2}{32} =\frac{1}{16}[/tex].

Answer:

w= -4

Step-by-step explanation:

First we know 8 x 4 is 32 so then we make the 8 negative

and divide -8 by 32 which is -4

You can check it by doing -4 x -8 which is 32!

Remember-

1. When you multiply two negatives it equals a positive.

2. You can check by plugging -4 where w is  then solving.

3. If there is a subtraction next to a number  (w-8) then whichever number the subtraction sign is in front of is negative.

4. If a variable is next to a number it means to multiply the variable  by the number.

From the given question, the required answer is option D. It can be deduced that: Reflect ΔECD over segment AC. This establishes that ∠ACB ≅ ∠E'C'D'. Then, (translate point E' to point A). This establishes that (∠D'E'C' ≅ ∠BAC). Therefore, ΔACB ~ ΔECD by the AA similarity postulate.

Rigid transformation is a process of resizing a given shape or figure. This can be done by either increasing or decreasing its dimensions (size) or changing its orientation. Some of the methods required in rigid transformation are: reflection, translation, rotation etc.

From the given question,

if ΔECD is first reflected over (turned about) segment AC, it would be deduced that m∠ACB ≅ m∠E'C'D' = [tex]90^{o}[/tex](right angle principle).

Then, the next process is to translate (extend) point E' to point A, so that m∠D'E'C' ≅ m∠BAC.

This would also ensure that m∠E'D'C' ≅ m∠ABC due to the translation.

This implies that ΔACB ~ ΔECD by the AA similarity postulate.

Therefore, performing reflection and translation operations on ΔECD step-wisely can be used to prove that ΔACB ~ ΔECD by the AA similarity postulate.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Point D coordinates = (-3, -2)

The point is dilated with a scale factor of 2.
