By the question we know that the number of students who spends less than 4 hours a week on screen is:
9 + 9 = 18
And among the 18 students there are 9 students whose grade average is below 80. So the percentage of the students who spends 4 hours a week on screen is:
= 9 ÷ 18 × 100%
= 100/2
= 50%
hence 50% students spend less than 4 hours a week on screens.

A furniture company created an L-shaped table by removing part of a square table.
a. Write an expression that represents the area of the L-shaped table.
b. What are all the side lengths of the L-shaped table?
c. The furniture company decides to create another table with the same area, but needs this table to be rectangular. What are the possible dimensions of the rectangular table? Explain.
Answers
Answer:
Step-by-step explanation:
(a) Identity: [tex](a-b)^{2}[/tex] = [tex]a^2 - 2ab + b^2[/tex]
Here, [tex](a-b)^2[/tex] represents the perimeter of room.
a = 10p
b= n
∴ area of l-shaped table room = [tex](10p-n)^2[/tex]
[tex](10p-n)^2 = (10p)^2 - 2(10p)(n) + n^2[/tex]
I will think about (b) and (c) part. Hope this much helps.

What is The Diary of Anne Frank?: It's the first, and sometimes only, exposure many people have to the history of the Holocaust.
1. How is this scene the happiest they have been since going into hiding?
In my opinion, this scene is the happiest they have been since going into hiding because the holocaust was very brutal because many individuals got executed and frightened throughout the Holocaust, and opening the gifts was a good way to temporarily forget about their problems.
2. Why does Margot not want to blow out the candles? Why does Mr. Frank say they need to?
Margot does not want to blow out the candles because they are supposed to be left to burn themselves out. Mr. Frank tells her God will understand that they need to conserve their Candles.
3. Explain Peter's prank on Mr. Dussel.
Peter was coming from his room as he was holding something in his coat which turned out to be a towel, but Mr. Dussel thought it was a cat. In the end, he was allergic to his clothes.
4. How does everyone react to Mr. Dussel's cat allergy?
Some seem to laugh at Mr. Dussel's cat allergy, but Mr. Van Dans wants to throw out Peter's cat for always eating their food. Peter said if Mr. Van Daans throws out the cat he will go out with it, but it didn't happen.
5. What happens that makes the mood change?
Something crashes below and they all freeze in horror. Peter tries to reach the lamp, but he can't so he gets up on a chair to try again but he ends up losing his balance and falling and then more steps can be heard below.
6. How was this scene the most scared
they have been since going into hiding?
Because they thought it was the Green Police or the Gestapo that have discovered their hiding place and had come to get them.
7. Describe juxtaposition and explain how this scene is an example of juxtaposition.
A writer can make readers sense of "goodness" in a particular character by placing him or her side-by-side with a character that is
predominantly "evil." In my opinion, this scene is an example of juxtaposition when Peter and Mr.
Van Dans had an argument about the cat, making Peter seem like a positive character while making Mr. Van Dans look like a negative character.
8. Describe how each person reacts in the situation when they are scared.
Mrs. Van Dans was panicking and saying to give the Green Police money
Anne was more concerned for her father because he went to check what happened below while her mother was trying to calmly put her in a state of relief. At some point, Anne asked who is going to look for Mr. Frank and Peter offered to show that he wasn't scared of any danger but Mr.
Dussel pushed Peter away in an angry tone. Mr.
Van Dans was as well calm and seemed to be more focused on what could happen next.
(I hope I did get every one right )
9. List the gifts that Anne gave to each person for Hanukkah. Then show how these gifts represent Anne maturing by saying what the thought or meaning behind each gift is.
1. Margot Frank: A crossword puzzle book / She never loses her temper.
2. Mrs. Van Dans: Hair shampoo / Mrs. Van Dans likes her hair (it doesn't seem to say in this scene, so I don't exactly know)
3. Mr. Van Dans: 2 cigarettes / Mr. Van Dans enjoys smoking (same as above)
4. Mrs. Frank: Ten hours of Anne doing what she says / Anne didn't get the time to repay her (that's what it made me believe)
5. Mr. Frank: A scarf / He found it in the first
scene
6. Mushi: A ball of paper with a string attached to it / For the cat to play with and stay entertained.
7. Peter: a safety razor / Peter was growing a mustache.
8. Mr. Dussel: earplugs / So he won't hear Anne making noise at night
Anne is maturing way faster because of the problems of what happens outside of their hiding as well. Every meaning of the gifts shows that Anne can see every little detail about people which not many kids can do.
l am sorry if l'm late, I had to do some research and listen to the audiobook of the specific scene.
I hope it was helpful! :]

Consider the following points on the graphs of y = sin(x) and y = sin(2x), with the added vertical dashed lines:
What are c and d?
Answers
Recall that [tex]\sin 2x=2\sin x \cos x[/tex].
If [tex]\sin a=-4/5[/tex], then [tex]\cos a=-3/5[/tex].
[tex]c=\sin(2a)=2(-4/5)(-3/5)=24/25[/tex]
Using similar logic, [tex]d=120/169[/tex].
The value of the variables are,
c = - 24/25 and d = 120/169
From the given graph we can see that two functions,
y = sin (x) and y = sin (2x)
Now, (a, -4/5) lies on y = sin x so,
sin (a) = - 4/5
cos (a) = √(1 - sin² (a)) = √[1 - 16/25] = √9/25 = 3/5 [since cosine function is positive in between - π and 0]
Again (a, c) lies on the y = sin 2x so,
c = sin (2a) = 2 sin (a) cos (a) = 2 (-4/5) (3/5) = - 24/25
Further,
(b, 5/13) lies on y = sin x so,
sin b = 5/13
cos b = √(1 - sin² (a)) = √[1 - 25/169] = √144/169 = 12/13 [since cosine function is positive in between 0 and π/2]
Again, (b, d) lies on y = sin (2x) so,
d = sin 2b = 2 sin (b) cos (b) = 2 (5/13) (12/13) = 120/169

Suppose a pilot is flying a speed jet at an altitude of `30000` ft when she recognizes her jet is soon going to run out of fuel.
She requests an aerial refueling, and begins to descend at a constant rate of `100` vertical feet per minute so she can refuel at a safer altitude.
The refueling plane takes off from ground level at the same time as the speed jet begins descent, ascending at a speed of `400` vertical feet per minute.
The refueling plane begins refueling the speed jet when the two planes reach the same altitude, at which point the refueling plane will position itself below the speed jet and connect to the jet's fuel tank.
Write two equations in the form `y=mx+b` to represent the situation. Use the variables `x` and `y`.

The student forgot to divide the factors, 5 and 6, by the "a" value. In this case, that is 2. Then, simplify the fractions. Once we have these values, the numerator is the constant value and the denominator is the coefficient.
5/2 = 5/2 ➜ (2x + 5)
6/2 = 3 ➜ (x + 3)
This student should have factored the expression as;
(2x + 5)(x + 3)
Answer:
(2x + 5)(x+3) = 0
Step-by-step explanation:
ac = 5 * 6 = 30
b = 5 + 6 = 11
Factorizing 2x² + 11x + 15,
2x² + 6x + 5x + 15 = 0
2x(x + 3) + 5(x+3) = 0
(2x + 5)(x+3) = 0
∴ x = [tex]\frac{-5}{2}[/tex], -3
(There was a mistake probably because the quadratic equation was considered with 1 as the coefficient as x², so the factorized equation was for x² + 11x + 30. You must take the coefficient of x² as 2 instead, according to the given equation.)

Answer:
Step-by-step explanation:
-2(6x+36)-7x [tex]\leq[/tex] 23
First, multiply -2 with the terms on the parenthesis, using the distributive law
-12x-72-7x[tex]\leq[/tex]23
Then we gather similar terms, x with x, no x with no x
-12x-7x-72 [tex]\leq[/tex] 23
do -12x and -7x calculation
-19x-72[tex]\leq[/tex]23.
Since we want to find the X, we highlight it turning it into the first term
-19x[tex]\leq[/tex]23+72
then add 23 + 72
-19x[tex]\leq[/tex]95
then divide all members on the equation by -19
-19x/(-19)[tex]\geq[/tex]95/(-19)
x[tex]\geq[/tex] -5.
Now, 6x + 10 > 40
since we want to find x, we make it the first term of the inequation

divide all members by 6

QUESTION:Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?
ANSWERS:
A V = π(18h)2V = π ( 18 h ) 2
B V = π(9)2hV = π ( 9 ) 2 h
C V = π(18)2hV = π ( 18 ) 2 h
D V = π(9h)2
Answers
Answer: B [tex]v=\pi 9^{2} h[/tex]
Step-by-step explanation:
to find volume use V=π r^2 h
if the diameter is 18 feet then the radius (r) will be half of that, 9 ft. So, to find the volume we'd just replace the r with 9 in the equation.
