Rocky purchased a guitar and Guitar Mart that was originally priced at $145.00. After tax, the final cost was $152.25. What was the percent of tax?
Answers
Given:
Original price = $145.00
Final cost = $152.25
To find:
The percent of tax.
Solution:
The formula for tax is:
Tax = Final cost - Original price
[tex]\text{Tax}=\$152.25-\$145.00[/tex]
[tex]\text{Tax}=\$7.25[/tex]
Formula for tax percentage is:
[tex]\text{Tax percent}=\dfrac{\text{Tax}}{\text{Original price}}\times 100[/tex]
[tex]\text{Tax percent}=\dfrac{7.25}{145.00}\times 100[/tex]
[tex]\text{Tax percent}=\dfrac{725.00}{145.00}[/tex]
[tex]\text{Tax percent}=5[/tex]
Therefore, the percent of tax is 5%.

LHS = (cosA+cosB)²+(sinA+sinB)²
= (cos²A+2cosAcosB+cos²B)+
(sin²A+2sinAsinB+sin²B)
/* By algebraic identity:

Rearranging the terms, we get
= (cos²A+sin²A)+(cos²B+sin²B)+2(cosAcosB+sinAsinB)

Find the x- and y-intercept of the line.
2x + 3y = -18
Answers
Hi there!
»»————- ★ ————-««
I believe your answer is:
X - Intercept: (-9, 0)
Y - Intercept: (0, -6)
»»————- ★ ————-««
Here’s why:
The x and y-intercepts of a line is where a given function intercepts the x or y axes.
I have graphed the equation given on a program. The graph shows that the line passes through the points (0, -6) and (-9, 0).
Therefore:
[tex]\rightarrow\text{The x-intercept of the given equation is }\boxed{\text{(-9,0)}}.\\\\\rightarrow\text{The y-intercept of the given equation is }\boxed{\text{(0,-6)}}.[/tex]
See the graph attached below!
»»————- ★ ————-««
Another way to solve this problem is to do this algebraically.
[tex]\text{X-Intercept: Substitute the 'y' variable for zero and solve for 'x'.}\\\\2x + 3y = -18\\-------\\\rightarrow2x+3(0)=-18\\\\\rightarrow2x=-18\\\\\rightarrow\frac{2x=-18}{2}\\\\\rightarrow\boxed{x=-9}\\-------\\\boxed{\text{X-Intercept: (-9,0)}}[/tex]
----------------------------
[tex]\text{Y-Intercept: Substitute the 'x' variable for zero and solve for 'y'.}\\\\2x+3y=-18\\\-------\\\rightarrow2(0)+3y=-18\\\\\rightarrow3y=-18\\\\\rightarrow\frac{3y=-18}{3} \\\\\rightarrow\boxed{y=-6}\\\-----\\\\\boxed{\text{Y-Intercept: (0,-6)}}[/tex]

Describe the transformation (s) (x, y) ----> (x + 2, y - 3)
Answers
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to describe transformation
As we can see, we added a value to the initial x and subtracted a value from the initial y
By adding to the initial x value, we are simply moving towards the right of the coordinate plane i.e we move towards the positive x axis
for the y axis value, we made a subtraction
what this mean is that we are actually going towards the negative y axis
So we move right on the positive x axis and move downwards to the negative y axis

Surface Area Formula for a Rectangular Prism: A = 2( wl + hl + hw)
w = width
l = length
h = height
In this picture, it shows that the height is 4, the width is 2, and the length is 3. Therefore, we have:
A = 2 [ (2*3) + (4*3) + (4*2) ]
A = 2(6 + 12 + 8)
A = 2(26)
A = 52
Thus, the surface area is 52 cm^2.

The denominator of the resulting fraction is

Answers

Answer:
(b) 6(a+1)
Step-by-step explanation:
Common factors are cancelled from numerator and denominator.
[tex]\displaystyle\frac{a^2-2a+1}{6}\div(a^2-1)=\frac{(a-1)^2}{6}\cdot\frac{1}{(a-1)(a+1)}\\\\=\frac{(a-1)(a-1)}{6(a-1)(a+1)}=\boxed{\frac{a-1}{6(a+1)}}[/tex]
The denominator of the result is 6(a+1).

The series diverges because it does not have a sum option, fourth is correct.
What is the convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.
We have an infinite series:
[tex]\rm \sum ^{\infty}_{n=1}\dfrac{3}{4}(2)^n[/tex]
[tex]\rm \sum ^{\infty}_{n=1}3(2)^{n-2}[/tex]
The above series is geometric series with first term 2 and the common ratio is 2.
Here 2>1
By the ratio test, the series is divergent.
Since the common ratio is greater than 1 the sum will be infinite.
Thus, the series diverges because it does not have a sum option, fourth is correct.

A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot. The glass costs $12 per square foot. How much will it cost to replace the glass? Use 3.14 for π.
Answers
Answer:
The image of the window can be seen below:
In the image we can see that the window can be separated in:
One rectangle of 4ft by 5 ft
Two half-circles (that if we add we get a complete circle) of diameter D = 4in.
First, we know that for a rectangle of length L and width W, the area is:
A = L*W
Then the area of our rectangle is:
A = 4ft*5ft = 20ft^2
And for a circle of diameter D, the area is:
A' = 3.14*(D/2)^2
In this case we have D = 4in, then the area of the circle (that we get when we add the areas of the two half-circles) is:
A' = 3.14*(4ft/2)^2 = 3.14*4 ft^2 = 12.56 ft^2
Then the total area of the window is:
Area = A + A' = 20 ft^2 + 12.56 ft^2 = 32.56 ft^2
And we know that each square foot of glass costs $12, then 32.56 square foots of glass will cost 32.56 times $12
Then the total cost is:
C = 32.56*$12 = $390.72
