Naher has a mirror in a shape of a circle.
The circle has a diameter of 60 cm.
Naher buys metal strips to put around the edge of the mirror.
The metal strip is sold in lengths of one meter.
Each one meter length of metal strip costs £5.68
Work out the total amount Naher paid.
Answer: £323.76
Step-by-step explanation:
Circumference = 2πr
= 2 x π x 30^2
= 2 x π x 900
= 1800π = 5654.9 cm = 56.549 meters
Amount paid 57m x £5.68 = £323.76
Jake paid $40.50 per solar panel for eight panels and an additional installation fee for a total of $338.50. Jen paid $42.99 per panel for eight panels and an additional installation fee for a total of $354.42. Find the difference between the installation fees Jake and Jen paid.
Answer: $4.00
Step-by-step explanation:
$40.50 * 8 = $324.00
$338.50 - $324.00 = $14.50
Jake’s installation fee is $14.50
$42.99 * 8 = $343.92
$354.42 - $343.92 = $10.50
Jen’s installation fee is $10.50
To find the difference between the two fees, you subtract the larger fee by the smaller fee.
$14.50 - $10.50 = $4.00
What is the area of the triangle given below? 2 and 6
Answer:
6 sq. units
Step-by-step explanation:
The area of a triangle is base times height divided by 2.

Answer:
y = 96°
Step-by-step explanation:
The measure of the inscribed angle y is half the measure of its intercepted arc.
The whole circle = 360°
the intercepted arc = 360° - 168° = 192°
Thus
y = [tex]\frac{1}{2}[/tex] × 192° = 96°

D. 5.8
Answer:
B) 6 inches

10x = 60
Divide both sides by 10
x = 6 inches
Our answer is B) 6 inches
A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the square? Use 3.14 for π, and round your answer to the nearest hundredth. 38.47 units2 94.99 units2 153.86 units2 379.94 units2
Answer:
Answer choice A) About 38.47 square units
Step-by-step explanation:
Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:
[tex]\dfrac{22}{2\pi}\approx 3.503[/tex]
Since the area of a circle is [tex]\pi r^2[/tex], the area of this circle is:
[tex]\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47[/tex]
Hope this helps!

In the picture above, parallel lines p and q are cut by transversal line t. If the measure of angle 4 is 43 degrees, then the measure of angle 6 is 43 degrees and the measure of angle 5 is ______ degrees. The measure of angle 8 is 43 degrees and the measure of angle 1 is _____ degrees.
Answer:
angle 5 is 137 degrees
angle 1 is 137 degrees
Step-by-step explanation:
angle 5 and 6 are supplementary angles meaning together they add up to 180 degrees. to find angle 5 you must find the difference:
[tex]180-43=137[/tex]
so angle 5 is 137 degrees.
likewise, angle 1 and angle 4 are supplementary angles. find the difference:
[tex]180-43=137[/tex]
so angle 1 is also 137 degrees.
The cost of each white tile was £2 the cost of each blue tile was 4 pounds work out the ratio of the total cost of the white tiles to the total of the blue tiles
Answer:
2x/4y = x/2y = x : 2y
Step-by-step explanation:
The question only gave us the cost of each white tiles and blue tiles respectively . The cost of each white tiles is £2 while the cost of each blue tiles is £4. The total cost of the blue tiles and the white tiles can only be calculated if we know the number of blue and white tiles available.
Let us assume
the number of white tiles = x
the number of blue tiles = y
total cost of white tiles = 2 × x = 2x
total cost of blue tiles = 4 × y = 4y
Therefore, the ratio of the total cost of white tiles to the total cost of the blue tiles can be expressed as follows
2x/4y = x/2y = x : 2y
If the number of white and blue tiles is known it can be replaced in the ratio to find the ratio of the total cost of the white tiles to the total cost of the blue cost.

Compute the probability that exactly 8 of the 20 internet browser users use chrome as their internet browser (to 4 decimals). for this question, if you compute the probability manually, make sure to carry at least six decimal digits in your calculations.
Answer:
2.4%
Step-by-step explanation:
We make use of the binomial probability equation, which is as follows:
P = [n! / (n - r)! r!] p ^ r * q ^ (n - r)
where,
n total number samples = 20
r is the selected number = 8
p, sin este valor no se puede realizar el ejercicio y no lo mencionas, pero encontré una pregunta igual y era de 20.37%, es decir 0.2037
q = 1 - 0.2037 = 0.7963
reemplazando:
P = [20! / ((20 - 8)! * 8!)] * [0.2037 ^ 8 * 0.7963 ^ (20 - 8)]
P = 125970 * 1.92685405*10^-7
P = 0.024 = 2.4%
Because you are working a late shift, you will get an increase in your wage. You will get and additional 10% per hour from 6:00pm to 12:00 am and additional 15% from 12:00 am to 1:00 am
CHECK THE COMPLETE QUESTION BELOW:
Supervisor: "Because you are working a late shift, you will get an increase in your wage. You will get an additional 10% per hour from 6:00 PM to 12:00 AM and additional 15% from 12:00 AM to 1:00 AM." Employee: "I am working from 2:00 PM to 12:00 AM. Between 2:00 PM and 6:00 PM, I will make $12.00 per hour. Between 6:00 PM and 12:00 AM, I will make __________ per hour
Answer:
I will make $13.2 per hour
Explanation:
It can be deducted from the question that that the money Employee gets money for Working from 2.00 PM to 6.00 PM = $12per hour
Also the Employee gets additional 10% of money for working from 6.00 PM to 12.00 AM which implies that
10% = (10/100)*$12per hour
=$1.2per hour
Again, Employee gets additional 15% of the money for working from 12.00 AM to 01.00 AM which can be calculated as:
15% = (15/100)*$12per hour
=$1.8 per hour
which means that Employee gets additional $1.8 per hour
of the money for working from 12.00 AM to 01.00 AM
Therefore, if Employee works from 2.00 PM to 12.00 AM,
Employee will gets money for Working from 2.00 PM to 6.00 PM as well as the 10\% extra wage which
= $12 + $1.2 = $13.2
= \$ 12 + \$ 1.2 = \$ 13.2

Answer:
The 3rd option
Step-by-step explanation:
To prove that 2 triangles are similar, we need to prove that 2 pairs of their angle measurements are congruent.
This is because all triangles have 180 degrees, so if 2 pairs are congruent, the remaining angles will also be congruent
We know that m<D=m<E
We also know that m<DCA=m<ECB because they are vertical angles.
Vertical angles are always congruent.
Therefore, the triangles are similar.
The correct similarity statement would be 1, since <D corresponds with <E.
Now let's look at the 3rd Statement. To prove that two lines are similar, we would have to prove that their alternate interior angles are congruent.
A pair of alternate interior angles would be <D and B or or <E and <A
There is no way to prove this, since we do not know any of the angle or that measurements or if the triangles are isosceles triangles.
Hence, the correct choice would be 1 only.

What is the solution to log2 (9x)- log2^3=3?
x=3/8. x=8/3
x=3
X=9
Answer:
x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Using the rule of logarithms
log x - log y = log ([tex]\frac{x}{y}[/tex] )
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]
Given
[tex]log_{2}[/tex] (9x) - [tex]log_{2}[/tex] 3 = 3
[tex]log_{2}[/tex] ([tex]\frac{9x}{3}[/tex] ) = 3
[tex]log_{2}[/tex] 3x = 3
3x = 2³ = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]
Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. A square labeled 16 x squared minus 40 x + 25 What is the side length, in inches, of the pet shop sign?
Answer:
length of side of square = (4x - 5) inches
Step-by-step explanation:
We are given;
Area of square = 16x² – 40x + 25
Let's find the roots of this quadratic equation [-b ± √(b² - 4ac)]/2a
Thus;
x = [-(-40) ± √((-40)² - 4(16 × 25)]/(2×16)
x = [40 ± √(1600 - 1600)]/32
x = (40 ± 0)/32
x = 40/32
x = 5/4
Thus, the factors of the polynomial are;
(4x - 5)²
So,
Area = 16x² – 40x + 25 = (4x - 5)²
Since, the right hand side is (4x - 5)² and area of square is (length of side)², thus we can say that length of side of square is (4x - 5) inches
