Answer: 500
Step-by-step explanation:
Given
The radius of the wheel is [tex]r=35\ cm\ or\ 0.35\ m[/tex]
Distance covered by wheel [tex]d=1100\ m[/tex]
Distance covered in one revolution is equal to the circumference of the wheel
Circumference of the wheel is [tex]2\pi r[/tex]
Insert the values
[tex]\Rightarrow 2\pi \times 0.35\\\Rightarrow 2.2\ m[/tex]
No of revolution is given by
[tex]\Rightarrow \dfrac{1100}{2.2}=500[/tex]
Thus, 500 revolutions is required.

Perform the indicated operation.
a^2 - 2a+1/6 divided by (a^2-1)= _________
The denominator of the resulting fraction is
→ 6(a - 1)
→6(a + 1)
→6
9514 1404 393
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).

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?
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%.

Answer: 680 cm^2
Step-by-step explanation:
The center inscribed triangle is congruent to the three other triangle it forms.
Since they are congruent, they share the same height value: 17.
The total height of the big triangle is twice the height of 2 smaller ones, so 34.
A=bh/2, 40*34/2= 680
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.
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

Draw a net to represent the three-dimensional figure indicated.
a. Right cylinder
answer:
you should be able to see the answer below.
step-by-step explanation:
imagine opening the actual shape and make sure the net diagram makes senseThe net is made up of two congruent rectangles and a circle. The rectangles are the bases of the cylinder, and the circle is the top.
The rectangles are connected by four flaps, which are the sides of the cylinder.
The dimensions of the net are as follows:
The length of each rectangle is equal to the circumference of the circle.
The width of each rectangle is equal to the height of the cylinder.
The radius of the circle is equal to the radius of the base of the cylinder.

Step-by-step explanation:
Describe the transformation (s) (x, y) ----> (x + 2, y - 3)
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

Find the x- and y-intercept of the line.
2x + 3y = -18
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]

Answer:
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.
(cosA+cosB)²+(sinA+sinB)²=4cos²(A-B/2)
