Layla was offered a job that paid a salary of $52,000 in its first year. The salary was set to increase by 2% per year every year. If Layla worked at the job for 16 years, what was the total amount of money earned over the 16 years, to the nearest whole number?
Answer:
$969,243 (nearest whole number)
Step-by-step explanation:
Use geometric sum formula:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
where [tex]a[/tex] is the initial value and [tex]r[/tex] is the common ratio
We have been told that the initial value is 52000, so [tex]a=52000[/tex].
If Layla's salary increases by 2% per year, this means it is 102% of the previous year's salary. 102% = 102/100 = 1.02. Therefore, [tex]r = 1.02[/tex]
We need to calculate the sum of money earned over 16 years, so [tex]n = 16[/tex]
Inputting these values into the formula:
[tex]\implies S_{16}=\dfrac{52000(1-1.02^{16})}{1-1.02}=\$969,243 \ \textsf{(nearest whole number)}[/tex]

The length of a rectangle is
3
meters less than
3
times the width. The perimeter is
34
meters. Find the width.
Answer:
Step-by-step explanation:
Create a system of equation for this.
We know that the perimeter is 2L+2W so
2L+2W=34
And 3W+3=L
Replace L with 3w+3.
2(3w+3)+2w=34
Simplify.
6w+6+2w=34
8w+6=34
8w=28
w=3.5.
Width is 3.5 meters.

Find value x and z!!!!!!!!!!!!!!!!!!
Answer:
[tex]x[/tex] = 3°
[tex]z[/tex] = 106°
Step-by-step explanation:
Since the angles are opposite each other, we know that [tex]9x+47[/tex] = 74°. We can use this information to solve for [tex]x[/tex]:
74° = [tex]9x+47[/tex]
27° = [tex]9x[/tex]
3° = [tex]x[/tex]
Since we know the whole system has to add up to 360°, or one rotation we can find what [tex]z[/tex] + the angle opposite it is equal to, and from there find [tex]z[/tex]:
360° = 2(74°) + 2[tex]z[/tex]
360° = 148° + 2[tex]z[/tex]
212° = 2[tex]z[/tex]
106° = [tex]z[/tex]
Given the figure below , find the values of x and z
Given : -Angle 1 = 74°Angle 2 = z°Angle 3 = ( 9x + 47 ) °To find : -Values of x and zConcept : -For doing such types of questions we must have concept and knowledge of linear pairs of angles and vertically opposite angles .
So let's Starting the Solution : -As we know that Angle 1 and Angle 3 are vertically opposite angles . Therefore , we can equate them and easily find the value of x . So :
9x + 47 = 749x = 74 - 479x = 27x = 27/9x = 3°Therefore , value of x is 3° .
Now Verifying :
9 ( x ) + 47 = 749 ( 3 ) + 47 = 7427 + 47 = 7474 = 74L.H.S = R.H.SHence , Verified .Therefore , our value for x is correct .
Now , finding value of z :As we know that Angle 1 and Angle 2 are Linear pair . Therefore , there sum is equal to 180° . So :
z + 74° = 180°z = 180° - 74°z = 106°Therefore , value of z is 106° .
Now Verifying :
106° + 74° = 180°180° = 180°L.H.S = R.H.SHence , Verified .Therefore, our answer is correct .

Your Answer:
Answer
Answer:
$135,150.18
Step-by-step explanation:
We're gonna use the quarterly compound interest formula: P = A(1 + r/4)⁴ⁿ
P = final amount (?)
A = starting amount (77,000)
r = rate (0.063)
n = years (9)
P = 77000(1 + 0.063/4)⁴ ˣ ⁹
P = 77000(1 + 0.063/4)³⁶
P = 77000(1.01575)³⁶
P = 77000(1.7551972)
P = 135,150.1844

Garrett earned $634.10 in net pay for working 27 hours. He paid $156.61 in federal and state taxes, and $61.24 in FICA taxes. What is Garrett's hourly wage?
Show work for 100 POINTS!!!
Answer:
$31.55
Step-by-step explanation:
Net pay = $634.10
Hours worked = 27
Taxes = $156.61
FICA = $61.24
Gross pay = earnings before taxes, benefits and other deductions
Net pay = earnings after all withholdings are accounted for
⇒ Gross pay = net pay + deductions
= $634.10 + $156.61 + $61.24
= $851.95
⇒ hourly wage = gross pay ÷ number of hours
= 851.95 ÷ 27
= $31.55 (nearest cent)
Gross income:-
Total money earned=634.1+156.61+61.24

(PLEASE HELP TYSM) Identify which variable to isolate, then solve for the variable and set up an equation containing one variable using substitution. Do not solve your final equation.
Problem 1 (on the left)
We can solve for y in the second equation since the coefficient here is 1.
Having coefficients that aren't -1 or 1 means we'd likely end up with fractions.
Add 5x to both sides like so:
y - 5x = 19
y = 5x+19
Now plug this into the first equation.
-3x - 8y = 20
-3x - 8( y ) = 20
-3x - 8( 5x+19 ) = 20
At this point, we have only one variable.
We stop here because your teacher does not want you to solve the final equation.
-------------------
Answers:
Variable to isolate: y
It leads to y = 5x+19 after solving the second equation for y.
And further leads to -3x - 8( 5x+19 ) = 20 after substitution.
======================================================
Problem 2 (on the right)
This time we can solve for x in the second equation. The reasoning is the same (coefficient of 1). Subtract 3y from both sides to get:
x+3y = 1
x = -3y+1
Substitute this into first equation.
Everywhere you see an x, replace it with -3y+1.
-3x - 3y = -15
-3( x ) - 3y = -15
-3( -3y+1 ) - 3y = -15
Like before, we now have one variable left.
-------------------
Answers:
Variable to isolate: x
It leads to x = -3y+1 when you solve for x in the second equation.
And further leads to -3( -3y+1 ) - 3y = -15 after substitution.
Use the quotient rule to prove that the power rule is valid for negative whole number powers.

Terms, coefficients and factors are what make up an algebraic expression
The factors of the expressionThe expression is given as:
(39.87 + 2(x-5))(1/2)
For an expression ab, the factors are a and b.
Hence, the factors of the expression (39.87 + 2(x-5))(1/2) are 39.87 + 2(x-5) and (1/2)
The terms in the first factorIn (a), we have the first factor to be:
(39.87 + 2(x-5))
For an expression a + b, the terms are a and b
Hence, the terms in the first factor are 39.87 and 2(x-5)
The coefficient in the second term of the first factorIn (b), we have the second term to be 2(x - 5)
For an expression 5a, the coefficient is 5
Hence, the coefficient in the second term of the first factor is 2
The number of ridesThis part of the question cannot be solved due to missing information

In the graph on the right, the demand for hot dog buns has changed because the price of hot dogs has risen from $2.00
to $2.50 per package.
The cross-price elasticity of demand between hot dogs and hot dog buns is (Use the midpoint formula and enter your
response rounded to two decimal places. Be sure to include the minus sign if hecessary)
The calculation depicts that the cross elasticity of demand will be -0.625.
How to calculate the elasticityFrom the graph, the percentage change in the price of hot dogs will be:
= (3-2)/[(3 + 2)/2]
= 1/2.50
= 0.40
The percentage change in the quantity of hot dogs will be:
= (7000 - 9000) / (9000 + 7000) / 2
= -2000/8000
= -0.25
The cross elasticity of demand will be:
= -0.25/0.40
= -0.625
In conclusion, the cross elasticity of demand is -0.625.
