Dan buys a car for £700.
It depreciates at a rate of 5.5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answer:
£469
Step-by-step explanation:
So 6 years mean it has depretiatied to 5.5*6 = 33% meaning the car is worth 67% of what it was originally worth
First do 700 / 100 to find what the car is equal to when it's 1% which is 7, after than multiply its new value of 67%,
so 7*67 = £469
Answer:
$469
Step-by-step explanation:
To find the amount of money that the car loses in value every year, multiply the price of the car by the rate its value depreciates at in decimal form.
The car depreciates at a rate of 5.5% per year. To find 5.5% in decimal form, move the decimal point to left twice. So, 5.5% in decimal form is 0.055.
700 * 0.055 = 38.5
The car loses $38.50 in value every year, so the car's value will depreciate by 6 times that amount in 6 years.
$38.50 * 6 = $231, so the car will lose $231 in value after 6 years.
700 - 231 = 469
The car will be worth $469 in 6 years.

Answer:
[tex]\sqrt{273}[/tex] units
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2
you have that a = 16 and c = 23, so:
16^2 + b^2 = 23^2
256 + b^2 = 529
b^2 = 273
b = [tex]\sqrt{273}[/tex]
Suppose that a piano costs $5,000 and loses 20% of its value each year. What will be the value of the piano after 16 years? A. $219.90 B. $274.88 C. $140.74 D. $175.92
Based on the information given will be the value of the piano after 16 years is : C. $140.74.
Using this formula
Time=Principal(1-rate)^n
Where:
Principal=$5,000
Rate=20%
Number of year=16 years
Let plug in the formula
Time=5,000(1-0.20)^16
Time=5,000(.80)^16
Time=$140.737
Time= $140.74 (Approximately)
Inconclusion the value of the piano after 16 years is : C. $140.74.

Answer:
49.92
Step-by-step explanation:
Square = 30
5 x 6 = 30
Half Circle = 9.42
6 x 3.14 = 18.84 divided 2 since it’s a half circle equals 9.42
Triangle = 7.5
3 x 5 = 15 divided by 2 = 7.5
So, 30+ 9.42 + 7.5 = 49.42
5. The table below represents a quadratic function: draw a graph plot points
What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?
Answer:
The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

What is the mode of the data set (30,28,30,45,40,37,35)
28
30
45
37
Answer:
30
Step-by-step explanation:
mode is the number that occurs most of the time
since 30 appears twice in the data set
while the other numbers only appear once,
30 is the mode
▪︎Mode is the most frequently occurring element in a given data set.
The given data set :
[tex] =\tt 30,28,30,45,40,37,35[/tex]
Let us first arrange these numbers in ascending order :
[tex] =\tt 28,30,30,35,37,40,45[/tex]
As we can clearly observe, the number 30 occurs the most frequently.
Thus, the mode of this data set = 30
Therefore, the correct option is (b) 30

One afternoon, a student who is 5 feet 4 inches tall measured shadows to find the height of a telephone pole. The student's shadow was 5 feet long. At the same time, the shadow of the telephone pole was 18 feet 9 inches long. How tall is the telephone pole?
Please help
Answer:
19.9875 feet
Step-by-step explanation:
The formula is given as:
Shadow of the student/Height of the student = Shadow of the telephone pole/Height of the telephone pole.
1 inch = 0.0833 feet
Shadow of the student = 5ft
Height of the student = 5 feet 4 inches
4 inches to feet
= 4 × 0.0833 feet
= 0.33 feet
Hence: Height of the student = 5 + 0.33 = 5.33 feet
Shadow of the telephone pole = 18 feet 9 inches long
9 inches to feet
= 9 × 0.0833 feet
= 0.75 feet
Hence: Shadow of the telephone pole = 18 + 0.75 = 18.75 feet
Height of the telephone pole= x
Therefore:
5/5.33 = 18.75/x
Cross Multiply
5x = 5.33 × 18.75
x = 5.33 × 18.75/5
x = 19.9875 feet
The height of the telephone pole = 19.9875 feet
