Answer:

R93,750. (I have changed R to $ in explanation)

Step-by-step explanation:

To determine the cost of the car inclusive of VAT, trade-in, and other fees, we first need to calculate the VAT amount. Assuming the VAT rate is 15%:

VAT = 0.15 x $75,000 = $11,250

Next, we can calculate the total cost of the car, inclusive of VAT:

Total cost of car = Cost of car + VAT

Total cost of car = $75,000 + $11,250

Total cost of car = $86,250

We also need to take into account the trade-in and the other fees. The trade-in value of $9,500 and the other fees of $2,000 are subtracted from the total cost of the car:

Total cost of car inclusive of VAT and other fees = Total cost of car + Trade-in value - Other fees

Total cost of car inclusive of VAT and other fees = $86,250 + $9,500 - $2,000

Total cost of car inclusive of VAT and other fees = $93,750

Therefore, the cost of the car, inclusive of VAT, trade-in, and other fees, is $93,750.

Answer:

let x as hotdog and x + 42 as soda

x + x + 42 = 250

2x + 42 = 250

2x + 42 - 42 = 250 - 42

2x = 208

x = 104

sodas sold: x + 42 = 104 + 42 = 146 sodas

hotdogs sold: x = 104 hotdogs

Step-by-step explanation:

Answer:

104 hot dogs sold

146 sodas sold

Step-by-step explanation:

s=number of sodas. h=number of hotdogs

s+h=250

s=h+42  ==> there were 42 more sells for soda than compared to hot dog

h+42+h=250  ==> plugin h+42 for s

h+h+42=250 ==> simplify

2h+42=250 ==> solve for h

2h+42-42=250-42 ==> isolate h by subtracting 42 on both sides

2h = 208

h = 208/2

h = 104 hot dogs sold

s=104+42  ==> plug in 104 for h in s=h+42

s = 146 sodas sold

The required solutions of the situation of the function are  x = 3/4  or x = -1/4.

A unique connection where each input only produces one output. A common notation for it is "f(x)," where x denotes the input value. as in f(x) = x/2 ("f of x equals x divided by 2") Since there is only one output ("x/2") for each input ("x"), it is a function: • f(2) = 1.

We have,

f(x)=2x-1

g(x)=3/8x

To find the value of x for f(x) = g(x).

f(x) = g(x)

2x-1 = 3/8x

16x² - 8x = 3

16x² - 8x - 3 = 0

16x² - 12x + 4x - 3 = 0

4x(4x - 3) + (4x - 3) = 0

(4x - 3)(4x + 1) = 0

x = 3/4  or x = -1/4

Thus, required solution are  x = 3/4  or x = -1/4.

Answer:

sister = 6 years

John=18 years

Step-by-step explanation:

A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.

Answer:

1. 10

2. if x was positive

3. if x was negative

Step-by-step explanation:

1. he starts on -2. so -2 + 12 is 10, so he would be on the space number 10.

2. if he moved to the right, it would mean you added something to 3. so, if x was positive, then it would move to the right.

3. if he moved to the left, it would mean that you subtracted something from 3. so, if x was negative, then it would move to the left.

For the given sequence a(26) = 2

To find a(26), we can use the recursive definition of the sequence and work our way up from a(0) and a(1):

a(0) = -1
a(1) = 1

a(2) = a(1) - a(0) = 1 - (-1) = 2
a(3) = a(2) - a(1) = 2 - 1 = 1
a(4) = a(3) - a(2) = 1 - 2 = -1
a(5) = a(4) - a(3) = -1 - 1 = -2
a(6) = a(5) - a(4) = -2 - (-1) = -1
a(7) = a(6) - a(5) = -1 - (-2) = 1
a(8) = a(7) - a(6) = 1 - (-1) = 2

From this pattern, we can see that the sequence repeats with a period of 6, so we can find a(26) by finding the remainder when 26 is divided by 6:

a(26) = a(26 mod 6) = a(2) = 2

Therefore, a(26) = 2.

The number of times the diameter of Uranus is larger than the diameter of Mars is 7.5 times

From the question, we have the following parameters that can be used in our computation:

The diameters of Uranus and Mars

These diameters are given as

Diameter of Uranus: 5.11×10^4 kilometers

Diameter of Mars: 6.79×10^3 kilometers

Express the diameters properly

So, we have the following representation

Diameter of Uranus: 5.11 × 10⁴ kilometers

Diameter of Mars: 6.79 × 10³ kilometers

This means that

Number of times larger = Diameter of Uranus/Diameter of Mars

Substitute the known values in the above equation, so, we have the following representation

Number of times larger = 5.11 × 10⁴ kilometers/6.79 × 10³ kilometers

Evaluate the quotient

So, we have the following representation

Number of times larger = 7.5

Hence, the number of times is 7.5

There is a probability of 66.5 % chance of it landing on a 5 at least once in 6 dice.

Because there are six faces on a die, you have an even chance of the dice landing on one of these faces each time you roll:

This means that each time that you roll, there is a 5/6 chance that you will not roll a 5.

The probability of not rolling a 6 twice is 5/6 or 69.4%.

Roll the die six times, and the probability of not rolling a 5 is

(5/6) * (5/6) * (5/6) * (5/6) * (5/6) * (5/6) * (5/6)

= (5/6)⁶

= 33.5%

Therefore, the probability of rolling a 5 at least once in 6 dice

= 100%  - 33.5%

= 66.5%

  The ant's entire distance travelled along its semicircular journey is its total distance travelled overall. The ant is travelling around a circle with radius R, thus the distance it has travelled is equal to half of the circle's circumference, πR.

The change in the ant's position is represented by a vector quantity called the displacement of the ant. The ant in this scenario begins at one end of the semi-circular path and moves 2R away from the beginning point to reach the other end. The direction of the displacement vector is from the starting point to the ending point, and the displacement's magnitude is equal to the 2R distance between the two points.

    So, the option c is most suitable option.

Therefore, πR and 2R are the ant's displacement and the distance travelled, respectively.

Step-by-step explanation:

It will pie r squared is equal to area

/ take this sign as pie

/ ×r^2=50/

r^2=50/÷/

r^2=50

r =

\( { \sqrt{50} } \)

=

\(5 \sqrt{2} \)

The value of the radius of the given circle is 5√2, of which the area is 50π m².

The formula for the area of a circle is A = πr², where A represents the area and r represents the radius.

As per the question, given that the area is 50π m².

So, we can set up the equation as follows:

50π = πr²

To solve for r, we divide both sides of the equation by π:

50 = r²

Taking the square root of both sides, we get:

√50 = √(r²)

Simplifying the square root of 50 gives:

r = √50

r = √(25 x 2)

r = 5√2

Therefore, the value of the radius is 5√2.

A stem and leaf plot, often known as a stem plot, is a method for categorizing discrete or continuous data. Data are organized as they are gathered using a stem and leaf plot. A stem and leaf plot resembles a bar graph in appearance. As each integer throughout the database is divided into a stem and a leaf, thus the name fits.

The last digit of each data point serves as the "leaf" in a stem and leaf plot, which divides the data into numerical points (the leading digit or digits).

\( \displaystyle \: \frac{6}{17.5-x} = \frac{8 + 6}{17.5} \)

simplify addition:

\( \displaystyle \: \frac{6}{17.5-x} = \frac{14}{17.5 } \)

simplify fraction;

\( \displaystyle \: \frac{6}{17.5 - x} = 0.8\)

The present value of the sequence of annual payments of Rs 25000 each, the first being made at the end of the 5th year and the last being paid at the end of the 12th year, if money is worth 6% is Rs. 158620.39.

1: We can use the formula to calculate the present value of the annuity:

P = A x [1 - (1+i)^-n] / i

Where

P = Present Value

A = Annuity

i = Interest Raten = Number of payments

2: Calculate the present value of each payment using the formula:

P1 = 25000 / (1.06)⁵

P2 = 25000 / (1.06)⁶

P3 = 25000 / (1.06)⁷

P4 = 25000 / (1.06)⁸

P5 = 25000 / (1.06)⁹

P6 = 25000 / (1.06)¹⁰

P7 = 25000 / (1.06)¹¹

P8 = 25000 / (1.06)¹²

3: Substitute the values into the formula to find the present value:

P = P1 + P2 + P3 + P4 + P5 + P6 + P7 + P8

P = (25000 / (1.06)⁵) + (25000 / (1.06)⁶) + (25000 / (1.06)⁷) + (25000 / (1.06)⁸) + (25000 / (1.06)⁹) + (25000 / (1.06)¹⁰) + (25000 / (1.06)¹¹) + (25000 / (1.06)¹²)
