Answer:
Step-by-step explanation:
Rudy's salary in terms of K notation is $80.6K if Rudy's job pays him $1,550 per week the answer is $80.6K.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Rudy's job pays him $1,550 per week.
As we know there are 52 weeks in one year.
The annual salary = $1,550x52
The annual salary = $80,600
In the K notation:
K = 1000
The annual salary in K notation = ($80,600/1000) K
The annual salary in K notation = $80.6K
Thus, Rudy's salary in terms of K notation is $80.6K if Rudy's job pays him $1,550 per week the answer is $80.6K.

Caroline needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 2. 75 hours and charged her $114 for parts. The total was $320. 25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answer:
$75 an hour - (320.25 - 114) / 2.75
Step-by-step explanation:
First, we have to deduct the amount for parts ($114) from the total ($320.25). Once we find the diffrence (206.25), we can divide it by the amount of hours it took (2.75). This leaves us with the answer, $75 an hour.
Consider the sequence of numbers: 2;5;2;9;2; 13;2;17 Calculate the sum of the first 100 terms of the sequence
A sequence of number can be arithmetic, geometric or neither
The sum of the first 100 terms is 29800
How to determine the sum of first 100 termsThe sequence is given as:
5, 9, 13, 17....
The above sequence is an arithmetic sequence, and it has the following parameters:
First term (a) = 5
Common difference (d) = 4
The sum of the first 100 terms is then calculated as:
[tex]S_n = \frac{n}{2} * (2a + (n -1)*d)[/tex]
Where n = 100
So, the equation becomes
[tex]S_{100} = \frac{100}{2} * (2*100 + (100 -1)*4)[/tex]
[tex]S_{100} = 29800[/tex]
Hence, the sum of the first 100 terms is 29800

Alina is an ecologist who studies the change in the bear population of Siberia over time.
The relationship between the elapsed time, t, in years, since Alina began studying the population, and the total
number of bears, N(t), is modeled by the following function:
t
N(t) = 2187 - (0.67)
Complete the following sentence about the yearly percent change of the bear population.
Every year,
% of bears are
added to / subtracted from
the bear population in Siberia.
Answer:
Subtracted from 33
Step-by-step explanation:
Every year, the bear population shrinks by a factor of 2/3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The exponential model is: N(t)=2187.(2/3)t
Let's analyze that function.
When t = 0, (2/3)⁰ = 1 and N(0) = 2,187 × 1 = 2,187
Thus, the population of bears starts with 2,187 individuals.
For t = 1, the population will be N(1) = 2,187 × (2/3).
For t = 2, the population will be N(2) = 2,187 × (2/3)²
And so on, every year the population of bears is multiplied by a factor of 2/3.
Since, 2/3 is less than 1, every year the population will be decreasing (decaying), by a factor of 2/3.
Thus, the answer, i.e. the complete sentence, is:
Every year, the bear population shrinks by a factor of 2/3.
Hence, Every year, the bear population shrinks by a factor of 2/3.

Find m∠LKM.
m∠LKM=
°
Answer:
∠ LKM = 125°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ LKM is an exterior angle of the triangle , then
3x - 70 = x + 60 ( subtract x from both sides )
2x - 70 = 60 ( add 70 to both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Then
∠ LKM = 3x - 70 = 3(65) - 70 = 195 - 70 = 125°
Four friends each brought matching necklaces and two pairs of earrings.The necklaces were priced at $25.00.If the total bill for all 4 friends was $156.00, what was the price of one pair of earrings?
Answer:
$7
Step-by-step explanation:
25x4=100
156-100=56
56/4=14
14 spent on earrings each earring was $7
If Four friends each brought matching necklaces and two pairs of earrings. The necklaces were priced at $25.00.If the total bill for all 4 friends was $156.00. Then 28 is the price of one pair of earrings
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Based on the conditions formulate
Four friends each brought matching necklaces
Cost of each necklace is 25
25x4=100
So for four necklaces it is 100.
Now with remaining amount they purchased two pairs of ear rings
156-100=56
With 56 they purchased earrings
56/2=28
Cost of one pair of ear rings is 28.
