How high can Ron lift a feather with his magic?
Answer: 705 cm
Step-by-step explanation:
Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525
centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.
How high can Ron lift a feather with his magic?
Hermione = 3,525 cm
Hermione = 5 × Ron
Substitute Hermione = 3,525 cm into
Hermione = 5 × Ron
3,525 = 5 × Ron
Ron = 3,525 / 5
= 705
Ron = 705 cm

Write the quadratic equation the has the roots (-1-√2)/3 and (-1+√2)/3 if its coefficient with x^2 is equal to...1
Step-by-step explanation:
x1+x2 = (-1-√2)/3 + (-1+√2)/3
= -2/3
(x1) (x2) = (-1-√2)/3 × (-1+√2)/3
= -1/9
the equation :
x² -(-2/3)x + (-1/9) = 0
x² + ⅔ x - 1/9 = 0
Which of these is NOT discrete data:
A. toppings on a pizza
B. boys in a family
C. temperature outside
D. planks in a deck
Answer:
C. temperature outside
Step-by-step explanation:
Discrete data is information that can only take certain values. ... This type of data is often represented using tally charts, bar charts or pie charts. Continuous data is data that can take any value. Height, weight, *TEMPERATURE* and length are all examples of CONTINUOUS data. = not discrete data

√(112) - √(80) / √(20) - √(28) = ?
[tex]\large\underline{\sf{Solution-}}[/tex]
We need to solve,
[tex]\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}[/tex]
We can write the above mentioned expression as,
[tex]\sf\longmapsto\dfrac{\sqrt{2\times2\times2\times2\times7}-\sqrt{2\times2\times2\times5}}{\sqrt{2\times2\times5}-\sqrt{2\times2\times7}}[/tex]
So,
[tex]\sf\longmapsto\dfrac{\sqrt{4\times4\times7}-\sqrt{4\times4\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}[/tex]
So,
[tex]\sf\longmapsto\dfrac{\sqrt{4^2\times7}-\sqrt{4^2\times5}}{\sqrt{2^2\times5}-\sqrt{2^2\times7}}[/tex]
Hence,
[tex]\sf\longmapsto\dfrac{4\sqrt{7}-4\sqrt{5}}{2\sqrt{5}-2\sqrt{7}}[/tex]
Taking common in respective terms,
[tex]\sf\longmapsto\dfrac{4(\sqrt{7}-\sqrt{5})}{2(\sqrt{5}-\sqrt{7})}[/tex]
On cancelling 4 with 2,
[tex]\sf\longmapsto\dfrac{4\!\!\!/^{\:2}(\sqrt{7}-\sqrt{5})}{2\!\!\!/(\sqrt{5}-\sqrt{7})}[/tex]
[tex]\sf\longmapsto\dfrac{2(\sqrt{7}-\sqrt{5})}{(\sqrt{5}-\sqrt{7})}[/tex]
Taking (-) common,
[tex]\sf\longmapsto\dfrac{-2(\sqrt{5}-\sqrt{7})}{(\sqrt{5}-\sqrt{7})}[/tex]
So, (√5 - √7) gets cut,
Hence,
[tex]\longmapsto\bf\dfrac{\sqrt{112}-\sqrt{80}}{\sqrt{20}-\sqrt{28}}=-2[/tex]

Line j passes through the points (-5,-2)
and (5,4).
Line k passes through the point
(-3,6) and is perpendicular to line j.
Find an equation for line k.
**the answer is probably in slope intercept form.
Answer:
y = - 5/3x + 1
Step-by-step explanation:
Slope of line j = (-2-4)/(-5-5)
Slope = -6/-10 = 3/5
Slope of the perpendicular line k: -5/3
Point of line k: (-3,6)
y-intercept of line k = 6 - (-5/3)(-3) = 6 - 5 = 1

f(x)=
Answer:
y = -1/2x + b meaning f(x) = -1/2x + b
Step-by-step explanation:
Use two points on the graph that you can find the value of or use Slope = raise/run
let use points (2,0) and (0, 1)
slope = (change in the y-value)/(change in the x-value.
slope = (1 - 0)/(0 - 2)
slope = 1/-2 or -1/2
Or starting at point (2, 0) the run(x movement) = -2 and the raise is 1.
slope = raise/run
slope = 1/-2 or -1/2
Using one point (2,0) and the slope of -1/2, substitute into the slope intersect form, y = mx + b, and solve for "b" .
y= mx + b
0 = -1/2(2) + b
0 = -1 + b
1 = b
Now write your equation: y = mx +b where m = -1/2 and b = 1
y = -1/2x +b

These transformations move the shape without making any Changes to its shape or size. A Reflection flips a shape over to create a mirror image. The dotted line in the video is like a Mirror. The copied second shape we see across the line is called an Image. It is exactly Opposite the first shape.

What is the slope of the line passing through the points (8, 9) and (-2, 9)?
Answer:
Slope is 0
Step-by-step explanation:
First, find the difference in the x and y of each point by subtraction.
8 - (-2) = 10
9 - 9 = 0
Because the y value doesn't change in between these two points, that indicates the slope is 0

P(A) is the power set of A. Show that-
(i) P(AUB) = P(A) ∩ P(B) is always true, but
(ii) P(AUB) = P(A) U P(B) may not be always true.
[tex]\large\underline{\sf{Solution-}}[/tex]
Let assume that,
[tex]\rm \longmapsto\:A \: = \:\{x\} \: [/tex]
and
[tex]\rm \longmapsto\:B \: = \:\{y\} \: [/tex]
[tex]\rm\implies \:A \: \cap \: B = \phi [/tex]
and
[tex]\rm \longmapsto\:A\cup B = \{x, \: y\}[/tex]
We know,
Power set of a set A is defined as set of subsets of A.
So,
[tex]\rm \longmapsto\:P(A) = \{ \phi ,\: x\}[/tex]
and
[tex]\rm \longmapsto\:P(B) = \{ \phi ,\: y\}[/tex]
and
[tex]\rm\implies \:P(A \: \cap \: B) =\{ \phi \}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
Now, Consider
[tex]\rm \longmapsto\:P(A)\cup P(B) = \{\phi ,x,y\}[/tex]
and
[tex]\rm \longmapsto\:P(A\cup B) = \{\phi ,x,y,xy\}[/tex]
[tex]\rm\implies \:\boxed{\tt{ \: P(A)\cup P(B) \: \ne \: P(A\cup B) \: }} \\ [/tex]
Now, Consider

one kilometer is 1000 meters complete the tables what is the interpretation of the constant of proportionality
Answer:
Step-by-step explanation:
Left side:
250=1/4 km (0.25)
12 meters=0.012
1 meter= 0.001
Right side: 5=5000 meters
20=20000 meters
Step-by-step explanation:
Left side: You divide each number by 1 km, and you should get the answer.
Right side: Do the same for the right side. But, instead of division, use multiplication.

Answer:

Subtract what you know 180-55-90 = 35
(6r-7)=35
35-7=28
28/6=4.66666
r=4.6666
Answer:
7
Step-by-step explanation:
90(right angle) + 55(Acute angle) = 145.
We know the whole angle equals 180 because it is 2 right angles. 90 + 90.
So, we will do 180 - 145 = 35.
Now we know our mystery angle equals 35.
To figure out r, we will do 35 + 7 = 42.
Then, 42 is divided by 6 and gets 7.
Therefore, 7 would be your answer.

for the functions u(t) = 7t - 2 and s(t) = t^2 - 9, what is s (u(2))?
Answer:
[tex]s(u(2)) = 135[/tex]
Step-by-step explanation:
[tex]u(t) = 7t - 2 \\ u(2) = 7(2) - 2 \\ u(2) = 14 - 2 \\ u(2) = 12 \\ \\ s(t) = {t}^{2} - 9 \\ s(u(2)) = {(12)}^{2} - 9 \\ s(u(2)) = 144 - 9 \\ \\ s(u(2)) = 135[/tex]

For the functions u(t) = 7t - 2 and s(t) = t² - 9. s(u(2)) = 135
What is a function?A function is a mathematical equation that shows the relationship between two variables.
For the functions u(t) = 7t - 2 and s(t) = t² - 9.To find what is s(u(2)), we proceed as follows.
Since u(t) = 7t - 2. Then u(2) is evaluated when t = 2. So, we have that
u(t) = 7t - 2
u(2) = 7(2) - 2
u(2) = 14 - 2
u(2) = 12
Now, since u(2) = 12 and s(t) = t² - 9
s(u(2)) is evaluated as follows
s(t) = t² - 9
s(u(2)) = 12² - 9
s(u(2)) = 144 - 9
s(u(2)) = 135
So, s(u(2)) = 135
