Answer:
Step-by-step explanation:
A)
A - the population after its decrease
x - the number of years in which there has been a decrease in population
Hence,
[tex]\displaystyle\\A=30000-475x\\A+475x=30000-475x+475x\\A+475x=30000\\A+475x-A=30000-A\\475x=30000-A[/tex]
Divide both parts of the equation by 475:
[tex]\displaystyle\\x=\frac{30000-A}{475}[/tex]
B)
[tex]\displaystyle\\x=\frac{30000-24300}{475} \\\\x=\frac{5700}{475}\\\\x=\frac{12*475}{475} \\\\x=12\ years[/tex]
What is 7[2.5 + 3(12 - 7)] and can you please show me how to do it
Answer: 122.5
Step-by-step explanation:
First, you have to do the distributive property for all numbers. In order to do that, you must first combine like terms.
Combining like terms are numbers that are in the parenthesis that don't have an exponent, variable, etc. In this case, you would combine 12 and -7 since they are in the same parenthesis case. 12-7 would be 5. Now, you have 7[2.5] + 3(5)]
Next, you use PEMDAS which means multiplication (parenthesis) is next which means you multiply 3 and 5. 3x5 - 15.
After that, you combine like terms again with the 2.5 and the 15 since the 15 is now out of the parenthesis. 2.5 + 15 = 17.5
Finally, you take the 7 and multiply that by 17.5 now that you have those 2 numbers left and they are in the brackets. 17.5x7 is 122.5!
However, if there is a variable to solve for, then the answer would be none/no solution because both sides are not equal.
The equation of line j is y+5=8(x+4). Perpendicular to line j is line k, which passes through the point (4, – 1). What is the equation of line k?
8x+y=31
perpendicular means the slopes are opposite reciprocals of each other. perpendicular to: y +5= 8(x +4) → m = 8 m⊥ = -8
Input the slope (m⊥ = -8) and the point (x₁, y₁) = (4, -1) into the Point-Slope formula: y - y₁ = m(x - x₁)
y - (-1) = -8(x -4)
y + 1 = -8 x + 32 simplified
8x+y =31

Show your work.
The number of students those who will most likely have their preference to do their classwork online is 238 out of 350
According to the question statement, A teacher surveys a random group of students about their preference for doing classwork online or on paper.
17 Preferred Online and 8 Preferred on paper.
We are supposed to find the number of students who will most likely have their preference to do their classwork online.
We will be using the concept of Probability for solving this.
[tex]Probability(Event)=\frac{Favourable Outcomes}{Total Outcomes}[/tex]
Probability(Event) = Favorable Outcomes/Total Outcomes
For the survey probability of students preferring online mode of classwork is = [tex]\frac{17}{17+8} =\frac{17}{25}[/tex]
= [tex]0.68[/tex]
Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68
Let the number students preferring online mode of classwork be "x"
so [tex]\frac{x}{350} =0.68[/tex]
or [tex]x=0.68*350\\x =238[/tex]
Therefore, the number of students those who will most likely have their preference to do their classwork online is 238 out of 350
Probability: P(A) = n(A)/n(S)where P(A) is the probability of an event “A”, n(A) is the number of favorable outcomes and n(S) is the total number of events in the sample space.

Multiplication is the opposite of division. When we multiply 4.15*3 we get 13.53.
What do you mean by multiplication?Multiplication is one of the four basic arithmetic operations, alongside the addition, subtraction, and division. In math, multiply means the repeated addition of groups of the equal sizes.
The symbols for multiplication are cross (x), asterisk (*), and dot (.). You seem to utilize the cross a lot when you write in your notebooks. In both algebra and computer languages, the asterisk and dot are symbols (higher mathematics).
Commutative Property: According to this property, when we multiply two numbers, the result will not change depending on the order.
Associative property: It states that if we multiply three or more numbers consecutively, the order is irrelevant.

Colton looks around at an assembly. he notices his younger sister to his right and his older brother 7 feet ahead of him. if colton's brother and sister are 8 feet apart, how far apart are colton and his younger sister? if necessary, round to the nearest tenth.
Colton is approximately 3.9 feet apart from his younger sister.
Pythagoras Theorem:
The statement o the Pythagoras theorem is, "if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides. "
Then it can be written as,
BC² = AB² + AC².
Where,
AB is the base,
AC is the altitude (height), and
BC is the hypotenuse.
Given,
Colton looks around at an assembly. he notices his younger sister to his right and his older brother 7 feet ahead of him.
And Colton's brother and sister are 8 feet apart.
Now, we need to find the distance between Colton and his younger sister.
Based on the given statement, we can draw their position like the following figure.
Here B represents the position of Colton, A represents the position of his older brother and C represents the position of his younger sister.
Now, we have to use the Pythagoras Theorem in order to solve it,
=> 8² = BC² + 7².
=> 64 = BC² + 49
=> 64 - 49 = BC²
=> BC² = 15
=> BC = √15
Therefore,
=> BC ≈ 3.9 feet
Therefore, the distance between Colden and his younger sister is approximately 3.9 feet.

Answer:
The answer is 2.72 * 10^8 sec.
Step-by-step explanation:
Distance between Earth and Sirius is 5.062 * 10^13 miles.
Time taken = Distance travelled/speed
5.062*10^13 miles/sec/1.86*10^5 miles.
=2.72 * 10^8 sec.
So this means that the time taken to travel light from Sirius to Earth is 2.72*10^8.

A yard has a perimeter of 190 feet. If four times the length of the yard equals 15 times the width, what are its dimensions
We get the dimensions of the park as length = 75 feet and width = 20 feet.
We are given that:
A yard has a perimeter of 190 feet.
Also, four times the length of the yard equals 15 times the width.
Now,
Let the length of the yard be x.
ATQ, we get the width of the yard as:
15 width = 4 x
Width = 4 / 15 x
Perimeter = 2 ( l + b )
190 = 2( x + 4 / 15 x )
95 = 19 x / 15
19 x = 95 × 15
19 x = 1425
x = 1425 / 19
x = 75 feet.
Length = 75 feet
Width = 4 / 15 x = 20 feet.
Therefore, we get the dimensions of the park as length = 75 feet and width = 20 feet.
