The area of the forest decreases by 6.25% each year, and after 15 years, the area will be approximately 1089 km.
The area of a forest is a crucial aspect of understanding its size and its impact on the environment.
In this question, we are know that the forest with an initial area of 2500 km, which decreases by 6.25% each year. Our task is to find the area of this forest after 15 years. To do this, we need to perform a calculation that takes into account the decrease in area each year.
Mathematically, we can represent the area of the forest after n years as:
A = 2500 * (1 - 0.0625)ⁿ
Where n is the number of years that have passed. To find the area after 15 years, we can plug in n = 15:
A = 2500 * (1 - 0.0625)¹⁵
Using the calculator provided, we find that the area of the forest after 15 years is approximately 1089.38 km. Rounding this to the nearest square kilometer, we get 1089 km.

what is the probability that the first son of a woman whose mother's brother has lesch-nyhan syndrome will be affected?
If a woman's uncle has Lesch-Nyhan syndrome and her father carries the mutation, the probability of her first son being affected is 50%.
Lesch-Nyhan syndrome is an X-linked recessive genetic disorder, which means it is caused by a mutation on the X chromosome and is passed down through families primarily from affected fathers to their daughters. The probability that a son of a woman with an affected uncle (mother's brother) will be affected depends on the genetic status of the woman's father and the mother's X chromosome that she inherited from her mother.
If the woman's father does not carry the mutation, she will not carry the mutation herself and cannot pass it on to her children. In this case, the probability of her first son being affected is 0%.
If the woman's father carries the mutation, she has a 50% chance of inheriting the mutated X chromosome from her father and a 50% chance of inheriting a normal X chromosome from her mother. In this case, if the woman is a carrier of the mutation, her first son has a 50% chance of inheriting the mutation from her and being affected.
It's important to note that this is a simplified answer and that more complex genetic testing and counseling may be necessary to determine the specific risk in a particular family.

A company fee pays a fee to use a song in their advertisement. There are 3 people in the band: the writer gets 4/12 of the fee, the singer gets 1/12 of the fee and the guitarist gets 1/12 of the fee.
What fraction of the fee does the whole band get??
Can u please help me I really need answers by this evening!!!
The whole band gets 1/2 of the fee.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
The writer gets 4/12 of the fee, the singer gets 1/12 of the fee and the guitarist gets 1/12 of the fee, so the total fraction of the fee that the band members get is 4/12 + 1/12 + 1/12 = 6/12.

What is a chord of circle?In Mathematics, a chord of circle can be defined as a line segment that typically join any two (2) points of a circle.
Generally speaking, the inscribed angle of a circle is equal to half of the central angle of a circle. Mathematically, this is given by this mathematical expression:
m∠STR = 1/2(SYR)
m∠STR = 1/2(50)
m∠STR = 50°.
m∠TSU = 1/2(TYU)
m∠TSU = 1/2(72)
m∠TSU = 36°.
For m∠SZT, we have the following:
m∠SZT = 180° - (m∠STR + m∠TSU)

With the values sin x= 3/5 and sin y= 2/3 , where x and y are both in first quadrant, then after calculation sin(x + y) = (3 * √(7/9)) / 5 + 1/2.
To evaluate sin(x + y), we can use the identity sin(a + b) = sin a cos b + cos a sin b.
Given that sin x = 3/5 and sin y = 2/3, we have:
sin(x + y) = sin x cos y + cos x sin y
= (3/5) * √(1 - (2/3)^2) + (√(1 - (3/5)^2)) * (2/3)
= (3/5) * √(7/9) + (4/5) * (2/3)
= (3 * √(7/9)) / 5 + (8/15)
= (3 * √(7/9)) / 5 + (8/15)

A pin can contain 3 numerical digit and no digit can be repeated. To calculate the amount of pins possible, we use 3! (3 factorial), which is 3x2x1, equaling 6. Then, we multiply this by 10, as there are 10 digits, 0-9. Therefore, 6x10 = 720. In order to calculate 3! (3 factorial) we start by multiplying 3x2x1. This is because each digit has to be multiplied by the number of digits before it, as no digit can be repeated. The first digit has no digits before it, so it stays as 3. The second digit has one digit before it, so it is multiplied by 2. The third digit has two digits before it, so it is multiplied by 1. Therefore, 3x2x1 = 6. Then, we multiply 6 by 10, as there are 10 digits, 0-9. 6x10 = 720, which means there are 720 possible pins with no digit being repeated.

A) between 10 and 15
B) between 15 and 20
C) between 20 and 25
D) between 25 and 30
A reasonable number of pages Carlos can write in 5 hours is between 20 and 25 pages.
Therefore the answer is C.
First, we need to find the average number of pages Carlos can write in one hour by dividing the number of pages he can write in 3/4 hour by 3/4:
(3 to 4 pages) / (3/4 hour) = 4 to 5.33 pages per hour
So, we can see that Carlos can write between 4 to 5.33 pages in an hour.
Next, we'll multiply that number by 5 to find the number of pages he can write in 5 hours:
(4 to 5.33 pages/hour ) * 5 hours = 20 to 26.65 pages
Since we can say that, he reads between 20 and 26 pages.

What are Trigonometric Functions?Trigonometric functions are defined as the real functions which are simply the functions of an angle of a triangle. They are basically the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.
Given a right angled triangle and an angle 30°.
Length of hypotenuse = 50 units
Sine of an angle in a right angled triangle is the ratio of opposite side to hypotenuse.
sin (30°) = x / 50
x = sin (30°) × 50
x = (1/2) × 50
x = 25 units
Cosine of an angle in a right angled triangle is the ratio of adjacent side to hypotenuse.
cos (30°) = y / 50
y = cos (30°) × 50
y = (√3 / 2) × 50
y = 25√3 units
Hence the value of x is 25 units and the value of y is 25√3 units.

Please help me i need help with this
Answer:
Please send a clearer image so I can answer question 1 and 3
Step-by-step explanation:
2: "One of the parallel lines can be translated so that it lands on the other line. After that, you would notice that the angles of the two lines have exactly the same measurement. Therefore, the interior and exterior angles of two parallel lines cut by transversal are equal."
5: The angles congruent to <8 are <6, <4, and <2
6: The value of m<6 = 70°
7: The equation to find <8 = 180 - <1
The measure m<8 = 85°
8: The value of x must be equal to 34
