Carolina, with the intention of investing money in real estate, acquired a plot of land for R$ 350,000.00. Over four years, the asset underwent changes in its commercial value, as follows variations:
First year: 12% appreciation
Second year: 10% appreciation
Third year: 8% devaluation
Fourth year: 6% appreciation
Having this information as a reference, it is correct to say that at the end of the analyzed period this plot of land
will have the value of:
(A) BRL 329,000.00.
(B) BRL 372,901.76.
(C) BRL 420,000.00.
(D) BRL 420,506.24.
(E) BRL 437,754.24.
At the end of the analyzed period this plot of land will have the value as given by: Option D: 420,506.24
What is appreciation and deprecation?Deprecation, also called devaluation, is the decrement in price of an asset. Appreciation is opposite of deprecation. This indicates increment in the price of the considered thing.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
It is given that:
Initial price of the plot of land = $350,000First year: 12% appreciationSecond year: 10% appreciationThird year: 8% devaluationFourth year: 6% appreciationNow, consider appreciation of an amount A by P%.
Then, we have:
Increased price = Initial price + P% of initial price
Increased price = [tex]A + \dfrac{A}{100} \times P = A \times \left(1 + \dfrac{P}{100} \right)[/tex]
Similarly, depreciated price by P% of an amount A is:
Decreased price = [tex]A - \dfrac{A}{100} \times P = A \times \left(1 - \dfrac{P}{100} \right)[/tex]
We've got: A = 350,000
After 1st year, which had 12% appreciation, we get:
[tex]A_1 =A(1 + 12/100) = A(1.12)\\[/tex]
After 2nd year, 10% appreciation we get:
[tex]A_2 =A_1(1 + 10/100) = A_1(1.1) = A(1.12)(1.1)\\[/tex]
After 3rd year, which had 8% devaluation effect on the price, we get:
[tex]A_3 = A_2(1 - 8/100) = A_2(1-0.08) = A_2(0.92) = A(1.12)(1.1)(0.92)[/tex]
After 4th year, which had 6% appreciation effect on the price, we get:[tex]A_4 = A_3(1 + 6/100) = A_4(1+0.06) = A_3(1.06) = A(1.12)(1.1)(0.92)(1.06)[/tex]
Thus, the final effect on A is:
[tex]A \rightarrow A(1.12)(1.1)(0.92)(1.06) = A(1.2014464)\\\$350,000 \rightarrow 350000(1.2014464) = 420506.24\: \rm dollars[/tex]
Thus, at the end of the analyzed period this plot of land will have the value as given by: Option D: 420,506.24

If the area of the rectangular base of Julian's tank is approximately 300 square inches, what is the approximate area of the rectangular base of his friend's tank?
302.5 square inches
468.75 square inches
750 square inches
375 square inches
The area of the rectangular base of his friend's tank is 468.75 square inches. So, Option D is correct.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
One of Julian's friends also has a rectangular aquarium.
The dimensions of his friend's tank are each exactly 1 1/4 times the dimensions of Julian's tank.
Let x be the length of Julian's tank.
Let y be the width of Julian's tank.
So, the Area of Julian's tank = length × Width
= xy
Since we are given
300 = xy
Now we are given that the dimensions of his friend's tank are each exactly times the dimensions of Julian's tank.
So, the length of his friend's tank = 5/4 x
So, the width of his friend's tank = 5/4 y
So, Area of his friend's tank = ( 5/4 x) (5/4 y)
= 25 / 16 xy
= 25 / 16 (300)
= 468.75
Hence the area of the rectangular base of his friend's tank is 468.75 square inches.
So, Option D is correct.

A plane and a sphere intersect in a circle that has an area of $48 \pi$. The distance between the plane and the center of the sphere is $3$ units. Find the surface area of the sphere.
The surface area of the sphere based on the information will be 2304π.
How to calculate the area?It should be noted that the radius of the circle will be 1/2 the length of the line. Therefore, the radius in the shape will be:
= 1/2 × 48
= 24 units.
Therefore, the area of the sphere will be:

What number comes
next in the pattern? The rule is "Multiply
the position number by itself." Describe a
feature of the pattern.
1,4,9,16,
Answer:
25 comes next
Step-by-step explanation:
okay so when it says "position" it means the numbers place in the order, for example "4" in this case would be the in the second position and "16" in the fourth position.
to get 1 you do: 1*1 because 1 is the first number and it is in the first (1) position.
To get the second number (4) you do: 2*2 because two is the second number (it comes after 1) and it is in the second position.
For 9, you do 3*3; the pattern here is squares, 1^2=1 2^2=4, 3^2=9, 4^2=16.
If we follow that pattern we will get 5^2=25

Step-by-step explanation:
a)
the total length of the outer or also only the inner perimeter ?
I assume the second case. but it is not difficult to change it to the outer perimeter case (per the information of b).
the total length consists of a straight side and 2 radius (left and right) of the end circles.
a radius is half the diameter, so 2×radius = 1 diameter.
so,
400 = length + 49
length = 400 - 49 = 351 m
the length of the straight sides is 351 m.
b)
the difference in length between both perimeters bases only on the difference in length of the circumference of the end circles. the lengths of the straight sides remain the same, not matter if outer or inner perimeter.
the circumference of 2 half circles is the circumference of 1 whole circle.
the circumference of a circle is
2×pi×r = pi×diameter
in our case for the inner perimeter
pi×49 = 153.93804... m
for the outer perimeter the radius and therefore the diameter changes : we have to add 6×1.5 m = 9 m on both sides of the circle
so, the radius of the outer circles is 9 m longer and the diameter 9×2 = 18 m longer : 49 + 18 = 67 m
so, we get for the outer circle perimeter
pi×67 = 210.4867078... m
therefore, the difference in the length of outer and inner perimeter is
210.4867078... - 153.93804... = 56.54866776... m
