Step-by-step explanation:
3/5 is the same as 6/10. All percentages are out of 100% so you have to change the denominater to 100. Do do that you just add a 0 to the numerator and demoninator. i.e. 60/100. which is translated to 60%.

Step-by-step explanation:
A good trick for fractions is to take the top number and divide it by the bottom number. This gives you the number version of the fraction. For example in question 4. 5/4 is 1.25. And 10/8 is 1.25. therefore they have the same value. Also another good trick. If the top number is more than the bottom number we know it will be 1 something because their is more than the bottom number. So if we have for example question 3 we know that 4 thirds will be at least 1 something if we divide it. And if we look at 8 ninths we know it will be less than 1 something since I is less than nine. Therefore if divided they will have different numbers

Answer:
(d) AE = (32√6)/3
Step-by-step explanation:
The side length ratios in a 30-60-90 triangle are 1 : √3 : 2. In a 45-45-90 triangle, they are 1 : 1 : √2.
So, we have the side length ratios ...
CE : CD = 2 : √3
BE : CE = √2 : 1
AE : BE = 2 : √3
Then the ratio AE : CE is ...
[tex]\dfrac{AE}{CD}=\dfrac{2}{\sqrt{3}}\cdot\dfrac{\sqrt{2}}{1}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{4\sqrt{2}}{3}[/tex]
Multiplying by the length of CD, we have ...
AE = (8√3)(4√2)/3
AE = (32√6)/3 . . . . . matches the last choice

How does Reflection work in real-life situations?
Answer:
reflection is defined as the change in the direction of a wavefront at the interface between two different media, bouncing the wavefront back into the original medium. A common example of reflection is reflected light from a mirror or a still pool of water, but reflection affects other types of waves beside light.

Answer:
Area of the shaded region = 51 cm²
Step-by-step explanation:
Area of the smaller pentagon ABKHG = 17 cm²
Since, B is the midpoint of side AC,
Scale factor used to enlarge the sides = [tex]\frac{\text{Measure of side AC}}{\text{Measure of side AB}}[/tex]
= [tex]\frac{AC}{\frac{AC}{2}}[/tex]
= 2
Therefore, area scale factor of both the pentagons = (Dimensional scale factor)²
2² = [tex]\frac{\text{Area of AFEDC}}{\text{Area of ABKHG}}[/tex]
4 = [tex]\frac{\text{Area of AFEDC}}{17}[/tex]
Area of bigger pentagon AFEDC = 4 × 17
= 68 cm²
Area of the shaded region = Area of the bigger pentagon - Area of the smaller pentagon
= 68 - 17
= 51 cm²

If a set of parallel lines contains the two points, (-2, 3) and (8, -5). If the lines are rotated 180 degrees clockwise, what would the two coordinates be after the rotation? Show or explain your work.
The two coordinates after the rotation are (2,-3) and (-8,5)
How to determine the coordinates after rotation?The points are given as:
(-2,3) and (8,-5)
The rule of 180 degrees clockwise rotation is:
(x,y) = (-x,-y)
This means that:
(2,-3) => (-2,3)
(-8,5) => (8,-5)
Hence, the two coordinates after the rotation are (2,-3) and (-8,5)

https://brainly.com/question/16691874

Answer:
(2, -3) and (-8, 5)
Step-by-step explanation:
If a point is rotated 180° clockwise about the origin (0, 0) then:
(x, y) → (-x, -y)
Therefore,
(-2, 3) → (-(-2),-3) = (2, -3)
(8, -5) → (-8, -(-5)) = (-8, 5)
So the two coordinates after rotation would be (2, -3) and (-8, 5).

It takes 3 cleaners 4 hours to clean a room, how long would it take 4 people to clean the same room at the same rate? (Ratio)
Answer:
3 hoursStep-by-step explanation:
Let the number of cleaners be x
Let the time taken be y
This relationship is inverse
x = k/y
If x = 3 and y = 4
3 = k/4
k = 3*4
k = 12
To get the time it will take 4 people, we will substitute k = 12 and x = 4 into the expression x = k/y
x = 12/4
x = 3
Hence it will take 4 people 3 hours at the same rate

A large quantity of waste material contains metal. At the successive passes through a recovery
process the mass of the metal recovered is:
32kg at the first pass,
24kg at the second pass;
18kg at the third pass;
13,5kg at the fourth pass, and so on, to form a geometric sequence,
1. How much metal would be recovered at the eighth pass?
(Round off the answer to TWO decimal places)
Answer:
The amount of metal recovered at the eight pass is approximately 4.27 kg
Step-by-step explanation:
The mass of metal recovered formed the following geometric sequence;
32 kg, 24 kg, 18 kg, 13.5 kg
∴ The first term, a = 32 kg
The common ratio in the geometric sequence is found as follows;
r = a·r/a = 24 kg/(32 kg) = 0.75
r = a·r²/a·r = 18 kg/(24 kg) = 0.75
r = a·r³/a·r² = 13.5 kg/(18 kg) = 0.75
The mass of the metal recovered in the eight pass will be the 8th term of the geometric series given as follows;
nth term = a·rⁿ⁻¹
a = 32, r = 0.75, n = 8
∴ 8th term = 32·(0.75)⁸⁻¹ = 32·0.75⁷ = 2187/512 ≈ 4.27
The amount of metal recovered at the eight pass ≈ 4.27 kg.
The eight term of the geometric sequence is 4.27.
Geometric sequenceA geometric sequence is in the form:
aₙ = ar⁽ⁿ⁻¹⁾
where aₙ is the nth term, a is the first term and r is the common difference.
Given that a = 32, r = 24/32 = 0.75
The eight term is a₈ = 32(0.75)⁸⁻¹ = 4.27
The eight term of the geometric sequence is 4.27.

go to (0, 2)
go to (7,0)
go to (-3,2)
Answer:
The answer is D
Step-by-step explanation:
1.Angle D is 90 becuase any angle inscribed in a semi circle is a right angle.
2.Since c and 76 form a semi-circle. They add up to 180 so c=104.
3.Angle A is a inscribed angle of arc 76. So that means angle A is half of the arc 76.
Angle A=38.
4. Angle B can be found two ways,
Using triangle interior theorem, since we know 90 and 38 as our given degree, a triangle has 180 degrees, so our third angle ,b will add up to 180 so it will be 52.Angle b is a inscribed angle of arc c so it is half of arc C or 104. Angle B=52D is the answer

Which is parallel to the following y=2x+1
a. Y=2x +5
B. Y- =4 (x+1)
C, Y=(-⅓)x +4
D. Y= 3x +7
Answer:
a. y = 2x + 5
Step-by-step explanation:
f two lines are parallel to each other, they have the same slope.
The first line is y = 2x + 1. Its slope is 2.
A line parallel to this one will also have a slope of 2.
a. y = 2x + 5
This line also has a slope of 2. It is a possible choice.b. y = 4(x + 1)
This line has a slope of 4. It will not be parallel.c. y = (-1/3)x + 4
This line has a slope of -1/3. It will not be parallel.d. y = 3x + 7
This line has a slope of 3. It will not be parallel.Therefore, your answer is a. y = 2x + 5.
