Answer:
[tex]y=110678.5x+420100[/tex]
Step-by-step explanation:
Given in the question that in ;
Year(x) salary y ($)
2000 420,100
2008 1305528
And x=0 in 2000, then in 2008, x=8 so you can form a table for values of x and y as
x y
0 420,100
8 1305528
To come up with a linear equation, you need to find the slope,m
m=change in y values/change is x values
m=(1305528-420100)÷ (8-0)
m=885428/8 =110678.5
To find the equation
Δy values ÷ Δx values =m
Δy values=y-420,100
Δx values= x-0
m=110,678.5
[tex]\frac{y-420100}{x-0} =110678.5\\\\\\y-420100=110678.5(x)\\\\\\\\y=110678.5x+420100[/tex]
To add or subtract fractions with different denominators first find the equivalent fractions with a _ denominator
Answer: Common
Step-by-step explanation:
The answer is with a multiplication of denominators, because when you multiply the denominator of one fraction with the denominator of the other fraction, we will get product which could divide between both denominator
for example if you have the following equation:
2/3+2/4
and you multiply 3*4 =12
and you can use it to complete the equation as a common denominator

Mrs. Zhang’s bee farm has a population that is about 1 tenth as large as Mrs. Acquino’s bee farm. If Mrs. Zhang’s bee population is about 48,000, about how many bees does Mrs. Acquino have?
Help me please i will give u 20 points
Mrs. Zhang's is 1/10 the size of Mrs. Acquino's.
Since you know Mrs Zhang's, divide the amount she has by the fraction of hers.
48,000 / 1/10
When you divide by a fraction, reverse the fraction and multiply:
48,000 x 10/1 =
48000 x 10 = 480,000 bees.
To estimate Mrs. Aquino's bee population, multiply Mrs. Zhang's bee population, which is 48,000, by 10. Mrs. Acquino has approximately 480,000 bees on her farm.
Since Mrs. Zhang’s bee population is 48,000 and her farm is said to be 1 tenth as large as Mrs. Acquino’s, to find the population of Mrs. Aquino's bees, we need to multiply Mrs. Zhang’s bee population by 10. Performing the calculation:
48,000 × 10 = 480,000
So, Mrs. Aquino's bee farm has approximately 480,000 bees.
On a number line, will the square root of 20 be closer to 4.4 or 4.5
Answer: 4.5 would be closer
Step-by-step explanation: 4.4x4.4 is 19.36 which is about 64 points away and 4.5x4.5 is 20.25 which is 25 points away
Answer:
4.5
Step-by-step explanation:
Nearest of square root of 20
[tex]\sqrt{20}[/tex]
To choose closer from two numbers 4.4 or 4.5
First we find the square of both number.
Square of 4.4
[tex]4.4^2 = 19.36[/tex]
Square of 4.5
[tex]4.5^2=20.25[/tex]
Now compare the closer number from 20
Difference of, 20.25 - 20 = 0.25
Difference of, 20-19.36 = 0.64
As we know, 0.25<0.64
Hence, On number line square root closer to 4.5
The supermarket is advertising double coupons up to $1.25 this Friday only. Which coupon can be doubled?
$1.30 off shaving cream
$1.20 off dog food
$2.25 off body wash
$1.50 off markers
Answer:
1.20 off dog food
Step-by-step explanation:
Inequalities help us to compare two unequal expressions. The coupon that can be doubled is $1.25. The correct option is B.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the supermarket is advertising double coupons up to $1.25. Therefore, every coupon that has a value less than or equal to $1.25 will be doubled. Therefore, we can write the inequalities as,
x ≤ $1.25
Now, if we look at the given options then the only option that is less than $1.25 is the coupon for dog food.
1.20 < 1.25
Hence, the coupon that can be doubled is $1.25.

You are competing in a race. The table shows the times from last year's race you want your time to be last year's median time with an absolute
deviation of at most 5 minutes. Complete the inequality to represent the time in minutes) you hope to achieve
Answer:
[tex]27\leq x \leq37[/tex]
Step-by-step explanation:
Let's arrange the numbers from least to greatest:
20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48
The median is the "middle" number when arranged from least to greatest.
There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.
6th term = 32
7th term = 32
Average = (32+32)/2 = 32
Hence, median = 32
Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.
So, 32 - 5 = 27 & 32 + 5 = 37
Hence [tex]27\leq x \leq37[/tex]
To find the inequality range for race times, we must first arrange the times and find the median, which is 32 minutes. The desired race time with an absolute deviation of at most 5 minutes from the median results in the inequality 27 ≤ x ≤ 37.
Explanation:
To solve this problem, we need to arrange the given race times in order and find the median. Once we find the median, we can set up an inequality that represents a race time within 5 minutes more or less than this median time.
First, we arrange the race times in ascending order: 20, 31, 27, 32, 25, 42, 48, 28, 40, 38, 32. After putting them in the proper order (20, 25, 27, 28, 31, 32, 32, 38, 40, 42, 48), we find that the median, which is the middle value, is 32 minutes since there are 11 times, and the 6th time is the median.
Next, we want to have a race time with an absolute deviation of at most 5 minutes from the median (32 minutes). This gives us the inequality 27 ≤ x ≤ 37. So, the time you hope to achieve in the race is between 27 and 37 minutes.

What is 7909+1044 using algorithm
Answer:
8,953
Step-by-step explanation:
line up 7,909 and 1,044 like this :
7,909
+ 1,044
then add everything
Using the addition algorithm, first you align the numbers by place value, then starting from the rightmost position, you add each place numbers together. Accordingly, 7909 + 1044 equals 8953.
Explanation:The process of adding two numbers using the additon algorithm begins with lining up the numbers by their place values. Starting from the rightmost digit, which is the one's place, you add the numbers in each corresponding place together.
In this case, Adding 7909 and 1044:
You begin with the ones place (9+4), which equals 13. You put down the 3 and carry over the 1 to the next place. After the first step the result would look like this: 790_3 with 1 carried over. Next, you add the numbers in the tens place (0+4) and the carried over 1, which equals 5. So the result after the second step would look like this: 79_53. You then move to the hundreds place. Since there is no number to add with 9, you simply carry it down. So the result after the third step would look like this: 7_953. Finally, you add the numbers in the thousands place (7+1), which equals 8. Therefore, the final result of 7909 + 1044 using the addition algorithm is 8953. Learn more about Addition Algorithm here:

Given the sequence below, and that sequence has a domain of n 2 1, find the third
term.
f(n) = 3n+2
Answer:
11Step-by-step explanation:
f(n) = 3n + 2, n ≥ 1
Substitute n = 3:
f(3) = 3(3) + 2 = 9 + 2 = 11
The third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2. This can be obtained by substituting 3 in the sequence since we have to find the third term.
What is a sequence ?Sequence is an ordered list of terms with a specific order.For example, 3, 7, 11, 15, ...Calculate the third term :
Given that, the sequence ⇒ f(n) = 3n + 2
Since n ≥ 1, first term will be ⇒ f(1) = 3(1) + 2 = 5
Second term will be f(2) = 3(2) + 2 = 8
Third term will be f(3) = 3(3) + 2 = 11
Thus the sequence is 5, 8, 11, ... and the third term is 11.
Hence the third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2.

A vector has an x-component equal to 0.15 and a y-component is equal to 1.22 calculate the vectors direction relative to the positive x-axis
Answer:
The vector direction is 83.0° relative to the positive x-axis
Step-by-step explanation:
* Lets explain how to find the direction of a vector
- A vector is a quantity which has both magnitude and direction
- The vector has two components x-component and y-component
- The x-component = v cos Ф , and the y-component = v sin Ф,
where Ф is the angle between the vector and the positive part
of the x-axis
- The magnitude of the vector = [tex]\sqrt{x^{2}+y^{2}}[/tex]
- The direction of the vector = [tex]tan^{-1}(\frac{y}{x})[/tex]
* Lets solve the problem
∵ x-component of the vector = 0.15
∵ y-component of the vector = 1.22
- Both x-component and y-component are positive
∴ Ф will be between 0° and 90°
∵ The direction of the vector = [tex]tan^{-1}(\frac{y}{x})[/tex]
∴ The direction of the vector = [tex]tan^{-1}(\frac{1.22}{0.15})[/tex]
∴ The direction of the vector = 83.0°
* The vector direction is 83.0° relative to the positive x-axis
two angels are complementary one angle measures 3more than twice the other.
Answer:
29° and 61°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other angles = 2x + 3
Sum the angles and equate to 90
x + 2x + 3 = 90, that is
3x + 3 = 90 ( subtract 3 from both sides )
3x = 87 ( divide both sides by 3 )
x = 29
and 2x + 3 = (2 × 29) + 3 = 58 + 3 = 61
The two angles are 29° and 61°
