dougs monthly salary was $1250 when he recieved a 5% raise. Six months later he recieved another 2% raise. What is his annual salary after recieving both raise?
Final answer:
After receiving a 5% and then a 2% raise, Doug's annual salary becomes $16,065.
Explanation:
Let's calculate Doug's annual salary after receiving both raises. Initially, Doug's monthly salary was $1250. After a 5% raise, his new monthly salary becomes $1250 × 1.05 = $1312.50.
Six months later, he receives another 2% raise, which makes his monthly salary $1312.50 × 1.02 = $1338.75.
To find his annual salary after both raises, we simply multiply his final monthly salary by 12 (the number of months in a year).
Initial monthly salary = $1250
First 5% raise = $1250 + 0.05 × $1250
Second 2% raise = (first raise + 0.02 × first raise)
Multiply the final salary by 12 to get the annual salary
$1338.75 × 12 = $16,065.
Therefore, Doug's annual salary, after receiving both a 5% and 2% raise, is $16,065.

A rectangular room is 1.5 times as long as it is wide, and its perimeter is30 meters. find the dimension of the room.
Answer:
6 meters by 9 meters
Step-by-step explanation:
Step 1: Formula for perimeter of rectangle
Rectangle's perimeter = 2 (length) + 2 (width)
Rectangle's perimeter = 2 (length + width)
Step 2: Find the length and width in terms of x
Width = x
Length = 1.5 times width
Length = 1.5x
Step 3: Find x
Perimeter = 2(length + width)
30 = 2 (1.5x + x)
30/2 = 2.5x
15/2.5 = x
x = 6
Step 4: Find the length and width
Width = x = 6 meters
Length = 1.5x = 1.5(6) = 9 meters
Therefore, the dimensions of the room are 6 meters and 9 meters.
Answer:The dimensions of the room are...

An audio books club charges an initial joining fee of $20.00. The cost per audio book is $15.00. The graph shows the cost of belonging to the club as a function of audio books purchased. How will the graph change if the cost per audio book goes up by $1.00?
(The new function is shown by the dotted line.)
Answer:
The new function will have a steeper slope
Step-by-step explanation:
Let
x ----> the number of audio books purchased
y ---->the cost of belonging to the club in dollars
we know that
case 1 (Originally)
[tex]y=15x+20[/tex] ----> equation A
case 2 ( the cost per audio book goes up by $1.00)
The new equation is
[tex]y=(15+1)x+20[/tex]
[tex]y=16x+20[/tex]
The slope of the new function is greater than the slope of the original function
[tex]16\frac{\$}{audio\ book}>15\frac{\$}{audio\ book}[/tex]
The new function will have a steeper slope
The graph in the attached figure
If the cost per audio book goes up by $1.00, the graph will shift upward by $1.00 for every point on the graph.
Explanation:The graph represents the cost of belonging to an audio books club as a function of the number of audio books purchased. The x-axis represents the number of audio books and the y-axis represents the total cost. The initial joining fee of $20.00 is a fixed cost and stays the same regardless of the number of audio books purchased. The cost per audio book is $15.00. If the cost per audio book goes up by $1.00, the graph will shift upward by $1.00 for every point on the graph. This means the new function will be a parallel line to the original function, but shifted up by $1.00.

An architect designs a rectangular flower garden such that the width is exactly two-thirds if the length. If 240 feet of antique picket fencing are being used to enclose the garden, find the dimensions of the garden.
Answer:
The length of the rectangular flower garden is 72 feet and the width is 48 feet
Step-by-step explanation:
Let
L ----> the length of the rectangular flower garden in feet
W ---> the width of the rectangular flower garden in feet
we know that
The perimeter of the rectangular flower garden is
[tex]P=2(L+W)[/tex]
we have that
[tex]P=240\ ft[/tex]
so
[tex]240=2(L+W)[/tex]
Simplify
[tex]120=(L+W)[/tex] -----> equation A
[tex]W=\frac{2}{3}L[/tex] ----> equation B
Substitute equation B in equation A and solve for L
[tex]120=(L+\frac{2}{3}L)[/tex]
[tex]120=\frac{5}{3}L[/tex]
[tex]L=120(3)/5[/tex]
[tex]L=72\ ft[/tex]
Find the value of W
[tex]W=\frac{2}{3}(72)[/tex]
[tex]W=48\ ft[/tex]
therefore
The length of the rectangular flower garden is 72 feet and the width is 48 feet

-2x + 2y = 6 and 4x + 2y= -5 solve by substitution
The solution to the system of equations by substitution is [tex]\( x = -\frac{11}{6} \)[/tex] and [tex]\( y = \frac{7}{6} \)[/tex].
To solve the system of equations by substitution, we can solve one equation for one variable and then substitute that expression into the other equation.
Given the system of equations:
1) [tex]\( -2x + 2y = 6 \)[/tex]
2) [tex]\( 4x + 2y = -5 \)[/tex]
From equation (1), we can solve for [tex]\( y \)[/tex] in terms of [tex]\( x \)[/tex]:
[tex]\[ -2x + 2y = 6 \][/tex]
[tex]\[ 2y = 2x + 6 \][/tex]
[tex]\[ y = x + 3 \][/tex] ... (i)
Now, substitute [tex]\( y \)[/tex] from equation (i) into equation (2):
[tex]\[ 4x + 2(x + 3) = -5 \][/tex]
Expand and solve for [tex]\( x \)[/tex]:
[tex]\[ 4x + 2x + 6 = -5 \][/tex]
[tex]\[ 6x + 6 = -5 \][/tex]
[tex]\[ 6x = -11 \][/tex]
[tex]\[ x = -\frac{11}{6} \][/tex]
Now, substitute [tex]\( x = -\frac{11}{6} \)[/tex] into equation (i) to find [tex]\( y \)[/tex]:
[tex]\[ y = -\frac{11}{6} + 3 \][/tex]
[tex]\[ y = -\frac{11}{6} + \frac{18}{6} \][/tex]
[tex]\[ y = \frac{7}{6} \][/tex]
So, the solution to the system of equations is:
[tex]\[ x = -\frac{11}{6} \][/tex]
[tex]\[ y = \frac{7}{6} \][/tex]
One trail through the park is 6.45 miles long. Another trail is 2.08 miles longer than the first trail. What is the combined distance of both trails
Final answer:
To find the combined distance of both trails, add the lengths of the two trails together. One trail is 6.45 miles long and the other is 2.08 miles longer.
Explanation:
To find the combined distance of both trails, we need to add the lengths of the two trails together. We know that one trail is 6.45 miles long, and the other trail is 2.08 miles longer than the first trail. So, the length of the second trail is 6.45 + 2.08 = 8.53 miles. To find the combined distance, we add the lengths of both trails: 6.45 + 8.53 = 14.98 miles.

The straight line y=2x-2 meets the circle x^2+y^2=8 at the points A and B. Find the length of AB, giving your answer correct to one decimal place.
Answer:
(12/5)√5
Step-by-step explanation:
y = 2x - 2
x² + y² = 8
x² + (2x - 2)² = 8
x² + 4x² - 8x + 4 = 8
5x² - 8x - 4 = 0
(5x + 2)(x - 2) = 0
x = -2/5
x = 2
y = 4 - 2
y = 2
(2,2)
y = 2(-2/5) - 2
y = -4/5 - 2
y = -14/5
(-2/5,-14/5)
√((2 + 2/5)² + (2 + 14/5)²)
√((12/5)²+ (24/5)²)
√(144/25 + 576/25)
(1/5)√(144+576)
(1/5)√720
(1/5)√(16*45)
(4/5)√45

Write 1.888... as a mixed number in simplest form
The conversion of 1.888... as a mixed number in the simplest form is [tex]\dfrac{17}{9}[/tex].
The number that repeats itself periodically after decimals is called Repeating numbers.
They are also called recurring numbers or non-repeating numbers.
They may be in a particular pattern or a single number may repeat.
Example : 2.1414141414…….
Assign a variable, x, to the repeating decimal:
x = 1.888........ (1)
Multiply both side by 10 to shift the decimal point:
10x = 18.888... (2)
Subtract equation 2nd from equation 1st,
10x - x = 18.888... - 1.888...
9x = 17
Divide both sides of the equation by 9, to get the value of x:
[tex]x = \dfrac{17}{9}[/tex]
The simplest form of 1.888... is [tex]\dfrac{17}{9}[/tex].
