Answer:
(attached file #2)
Step-by-step explanation:
let's change the variable n to a variable x (it can be x and y):
x ≥ -8
go to the X-axis which is the line going horizontal, just as the first picture attached!
2. Now go to the -8 on that line and draw a straight bold line going up (vertical)
and there you have the answer to the question.
if the question was with this symbol: < or > then the line would be dashed instead of being a bold solid straight line!

You have a pizza with diameter 12
2
3 in., and a square box that is 12.65 in. across. Write 12
2
3 as a decimal. Can you fit the pizza inside the box?
What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.
Step-by-step explanation:
Please help! Could you answer all!?
Answer:
1.) 48
2.) 65
3.) 36
Step-by-step explanation:
1.) If the equation is 6(x-4) and x = 12, then all we have to do is plug in the value of x. When we plug in, all we do is substitute 12 for x because they mentioned in the question that x = 12. So, we end up getting 6(12 - 4). After solving this, we get 48.
2.) This problem is a lot like the last problem. All we need to do is substitute /plug in the values of x and y into the equation, to get 4(4^2) - 35/7 - (8 + 14). After solving, we get 65.
3.) . This problem, once again, is also a lot like the last problems. We need to substitute the value of x into the equation 8x+12. Since we know from the problem that x is 3, all we have to do is 8 * 3 + 12.

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
Answer:
Step-by-step explanation:
To make the race close, the length of the race should be 450 meters.
Here's the reasoning behind the answer:
Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.
The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.
During this time, Henri would have walked a distance of 1 x 18 = 18 meters.
So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).
To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.
Let's call the total distance of the race "d."
So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).
We can set up an equation to solve for d:
d/1 = (d + 27)/2.5
Solving for d, we get:
d = 450
So, the race should be 450 meters long for Henri to win in a close race.
really dont understand can someone help me
Answer: 30.25 cm2.
Step-by-step explanation:
Given: Perimeter of a square = 22 cm.
Concept used: Area of a square = side2 Perimeter of a square = 4 × side.
Calculations: Let the side of the square be 'a' Perimeter of a square = 22 cm. ⇒ 4a = 22. ⇒ a = 5.5 cm. ...
∴ Area of square is 30.25 cm2.
Consider the equation below.
5(3a−1)−2(3a+2)=3(a+2)+v
Select two expressions that are equivalent to v.
Answer:
Its option C. 6a-7
Step-by-step explanation:
Given that 5(3a-1)-2(3a-2)=3(a+2)+v . You solve for v by:
v = 5(3a-1)-2(3a-2) - 3(a+2)
v = 15a - 5 - 6a + 4 - 3a - 6
v = 15a - 6a - 3a - 5 + 4 - 6
v = 6a - 7
So the answer is option C. 6a-7

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
A researcher posts a magazine advertisement offering $30 in exchange for participation in a short study. The researcher accepts the first three people who respond to the advertisement. Which of the following statements is true about the sample? (5 points)
a
It is not a valid sample because it is not a random sample of the population.
b
It is a valid sample because the first three people were selected to participate.
c
It is a valid sample because money was offered to participants.
d
It is not a valid sample because it is only a short study.
Answer:
Q1: D
Q2: D
Q3: B
Step-by-step explanation:
Q1: It says it in the question.
Q2: He asked the ones in his science class so they would obviously prefer science, but that is not true for the rest of the students.
Q3: It is random because the first 3 people were chosen regardless of who they were, and it is still a valid sample even if the study is short.

Answer:
Hello, for the first one, the answer should be (C) 3
The following transformation is an enlargement, meaning it would get bigger. Meaning that the scale factor increases by 3.
2x3=6
3x3=9
Therefore, the scale factor is (C) 3.
#5: The answer is (D): 4
Since this is an enlargement, we have to determine what ? x 6 = 24 is. Since the height of the photo is 6, we can conclude that 6 x 4 = 24.
Therefore, the answer is (D): 4

the parent’s height is 9 cm and the child’s height is 6 cm.
The child’s actual height is 1.3 m.
What is the actual height of the parent?
Answer:
1.95 m
Step-by-step explanation:
The ratio between the parent's height and the child's height stays the same.
Therefore, 9:6 = 1.5:1.
1.5:1 = x:1.3
Hence, after calculation, the parent's height is 1.95 m.

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

Write down in terms of n, an expression for the nth term of the following sequence b) -7 -12 -17 -22 -27
Answer:
If you were taught that the first element in the sequence is at n = 0:
-7 - 5n
If you were taught that the first element is at n = 1:
-2 -5n
Step-by-step explanation:
First, find a pattern in the elements of the sequence. At first glace, I notice that each consecutive number is the previous number minus 5.
Thus it can be seen that for each consecutive number in the sequence, 5 is subtracted from negative 2 n times! Therefore, the expression must be:
-2 - 5n
Let's double check the expression! When n = 3, it should equal -17.
-2 - 5(3) = -17
And when n = 5, it should be -27:
-2 - 5(5) = -27.
This is the case if the first element in your sequence is n = 1, if you've been taught that the first element is n = 0, the expression would be:
-7 - 5n
