Rewrite 3:
/45
We know that one pair of factors of 45 is 9 and 5. 9 is a perfect square— 3x3. Therefore, you will write it as 3/5
The number inside the sign cannot be squared in a while number while the number outside is already squared.
So you will rewrite inside the radical sign 9 • 5. To simplify it, you will find the square root of the perfect square. 3 *radical sign* 5
I hope that makes sense, feel free to shoot me a message if you’re confused. I’ll write the rest of the answers down below. Again, I will use / as the radical sign and rewrite 3 to make it easier.
Rewrite 3
/45
= /9•5
= /3•3•5
= 3/5
Rewrite 2
/28
= /4•7
= /2•2•7
= 2/7
Rewrite 1
/20
= /4•5
= /2•2•5
= 2/5
Rewrite 4
/36
= /6•6
= 6
^— This one is different because 36 is already a perfect square. 6•6=36
I had written out the multiplications of the squares because that was the way we were taught. We would cross out the same numbers and then write it outside the radical sign. Hope that helps :)

Complete the square
to find the vertex
of this parabola.

х
- 16 Y-4 x-12=0
Answers
Answer:
Vertex coordinates; (h,k) = (2, -1)
Step-by-step explanation:
Vertex form of a parabola is;
y = a(x - h)² + k
Now, we are given;
x² - 16y - 4x - 12 = 0
Rearranging, we have;
x² - 4x = 16y + 12
Let's complete the square on the left hand side;
First add square of half of the coefficient of x to both sides;
x² - 4x + (-½ × 4)² = 16y + 12 + (-½ × 4)²
x² - 4x + 4 = 16y + 12 + 4
LHS can be expressed as;
(x - 2)² = 16y + 16
16y = (x - 2)² - 16
Divide both sides by 16 to get;
y = (1/16)(x - 2)² - 1
Comparing this with y = a(x - h)² + k, we have;
a = 1/16
h = 2
k = -1
(h,k) = (2, -1)
Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)
a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class
c
No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class
d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

Answer: d. No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)
Answers
Answer:
6
Step-by-step explanation:
I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3 This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6 Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.
I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.

when u divide fractions, u flip the second fraction around and multiply
4/5 divide by 2/25

A is false (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.
B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )
C is false (H is positive and E is negative. Positive times a negative equals a negative.)
D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)
The rectangular pyramid below has a volume of 200 m3. What is the height of the rectangular pyramid in meters? If the base is 6 by 5 meters
Answers
Answer:
6.67meters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid = Length × Width × Height
From the question
Volume = 200m³
Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m
To find the height of the pyramid = Volume/Length × Width
Height = 200m³/ 6m × 5m
Height = 6.67m
Height of the rectangular pyramid in meters = 6.67 m
