Answer:
Data is distinct pieces of information, usually formatted in a special way.
Step-by-step explanation:
Ashton and Kamir are arguing about how a number trick they heard goes. Ashton tells Andrew to think of a number, multiply it by five and subtract three from the result. Kamir tells Andrew to think of a number, add five and multiply the result by three. Andrew says that whichever way he does the trick he gets the same answer. What was the number?key
Answer: The number was 9.
Step-by-step explanation:
Let the number be 'x;.
think of a number, multiply it by five and subtract three from the result :
According to Ashton, the expression would be :
[tex]5x-3[/tex]
Kamir tells Andrew to think of a number, add five and multiply the result by three:
According to Kamir, the expression would be :
[tex]3(x+5)[/tex]
At last, they get the same number :
[tex]5x-3=3(x+5)\\\\5x-3=3x+15\\\\5x-3x=15+3\\\\2x=18\\\\x=\dfrac{18}{2}\\\\x=9[/tex]
Hence, the number was 9.
By comparing Ashton's algebraic expression '5x-3' with Kamir's expression '3(x+5)', one can find that if these expressions are equal, the number x that Andrew was thinking of is 15.
Explanation:The subject of this question is Mathematics and it is suitable for a Middle School grade level. The trick that Ashton and Kamir are trying to figure out is based on one of the basic properties of numbers. Andrew says that regardless of the trick, he gets the same answer. This implies that the operations used in both tricks must have equivalent results. Let's use algebraic expressions to represent the steps in each trick. If the original number Andrew thinks of is x:
According to Andrew, these expressions are equal. So, we have the equation:
5x - 3 = 3(x + 5)
By solving this equation, you can find the original number that Andrew was thinking about, which is 15.

Answer:
The common difference is 1.5
Use the explicit formula to find a1.
a1 = 1.2
What is the explicit formula for the arithmetic sequence?
= 1.2 + (n - 1)1.5
Step-by-step explanation:
Final answer:
The common difference of the arithmetic sequence is 1.5, and the first term is 1.2. The explicit formula for the arithmetic sequence is A: an = 1.2 + (n - 1)1.5.
Explanation:
To find the common difference of an arithmetic sequence, we can use the information that the seventh term (a7) is 10.2 and the twelfth term (a12) is 17.7. The formula for the nth term of an arithmetic sequence is an = a1 + (n - 1)d, where a1 is the first term and d is the common difference. By creating a system of equations using the given terms, we can solve for d.
For the seventh term: 10.2 = a1 + 6d
For the twelfth term: 17.7 = a1 + 11d
Subtracting the first equation from the second gives: 17.7 - 10.2 = 5d, which simplifies to 7.5 = 5d or d = 1.5.
We can then plug the value of d back into one of the equations to find a1:
10.2 = a1 + 6(1.5)
10.2 = a1 + 9
a1 = 1.2
Therefore, the explicit formula for this arithmetic sequence is A: an = 1.2 + (n - 1)1.5.
What is the area of the figure?
10.2 in.
3 in.
3 in
2 in.
2 in.
8 in.
6.2 in
Answer:
B. 80.2
Step-by-step explanation:
The easiest way to find the area of this figure is to divide it into two rectangles.
First, let's find the area of the top rectangle.
10.2 * 3 = 30.6
The area of the top rectangle is 30.6 square in.
Now let's find the area of the second rectangle:
6.2 * 8 = 49.6
The area of the bottom rectangle is 49.6 square in.
Lastly, we have to add the areas of the two rectangles together.
30.6 + 49.6 = 80.2
The area of the entire figure is 80.2 square inches.
A plane flies from NY to Chicago, which is about 700 miles, at a speed of 330 mph. How long does the flight take? On a return trip, a tailwind (x) helps the plane move faster. (The plane still operates to produce a basic speed of 330 mph. The total flying time for the round trip is 3.7 hours so how fast is the tailwind?
The flight from NY to Chicago took roughly 2.12 hours, while the return flight took about 1.58 hours due to a tailwind. By using these times to calculate the speeds of the flights, we find that the tailwind was 113.04 mph.
Explanation:The flight time from NY to Chicago can be calculated by dividing the distance (700 miles) by the speed of the plane (330 mph). The result is about 2.12 hours. The total flight time for the round trip is given as 3.7 hours, so the return trip took about 1.58 hours. Divide 700 miles by 1.58 hours and we get a total speed of about 443.04 mph for the return trip. This speed includes both the speed of the plane (330 mph) and the speed of the tailwind (x). Therefore, to find the speed of the tailwind, subtract the speed of the plane from the total speed: 443.04 mph - 330 mph = 113.04 mph. So, the tailwind is 113.04 mph.

#SPJ12
The tailwind speed is found to be approximately 113.04 mph.
Let's find out the time it takes for the initial flight from NY to Chicago.
Distance from NY to Chicago: 700 milesSpeed of the plane: 330 mphTime = Distance / Speed = 700 miles / 330 mph ≈ 2.12 hoursNow, for the return trip, let the tailwind speed be denoted as x.
Speed of the plane with tailwind = 330 + x mphTotal flying time for the round trip: 3.7 hoursLet time for the return trip be t hours. Then, we have:
Time for round trip: 2.12 hours (to Chicago) + t hours (returning)So, t = 3.7 - 2.12 = 1.58 hoursTherefore, the equation for the return trip will be:
700 miles / (330 + x) = 1.58 hoursSolving for x:
330 + x = 700 miles / 1.58 hours ≈ 443.04 mphx ≈ 443.04 - 330 = 113.04 mph
The speed of the tailwind is approximately 113.04 mph.

Answer:
The fraction of the applicants who have passed the two phases of the selection process is [tex]\frac{10}{63}[/tex].
Step-by-step explanation:
The question is:
In the first phase of the selection process for the body of teachers they eliminate four-ninth of the applicants while in the second phase they eliminate 5/7 of those who passed the first phase. If there were 315 applicants what is the fraction of the applicants who have passed the two phases of the selection process?
The total number of applicants is
N = 315.
It is provided that 4/9th of the applicants were eliminated in the first phase.
Then the fraction of candidates who passed the first phase is:
Fraction who passed phase I = [tex]1-\frac{4}{9}=\frac{5}{9}[/tex]
Now, it is also provided that 5/7 of those who passed the first phase were eliminated in the second phase.
Then the fraction of candidates who passed the second phase is:
Fraction who passed phase II = [tex]1-\frac{5}{7}=\frac{2}{7}[/tex]
That is, 2/7 of the remaining applicants passed the second phase.
The fraction of the applicants who have passed the two phases is:
[tex]\frac{5}{9}\times \frac{2}{7}=\frac{10}{63}[/tex]
Thus, the fraction of the applicants who have passed the two phases of the selection process is [tex]\frac{10}{63}[/tex].

Solve for n:
3⁄5 · n = 6
Answer:
n = 10
Step-by-step explanation:
Solve for n:
(3 n)/5 = 6
Multiply both sides of (3 n)/5 = 6 by 5/3:
(5×3 n)/(3×5) = 5/3×6
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×6
5/3×6 = (5×6)/3:
(5×3 n)/(3×5) = (5×6)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×6)/3
6/3 = (3×2)/3 = 2:
n = 5×2
5×2 = 10:
Answer: n = 10
To solve for n in 3⁄5 · n = 6, divide both sides of the equation by 3⁄5. The solution is n = 10.
Explanation:To solve for n in the equation 3⁄5 · n = 6, we need to isolate n on one side of the equation. To do this, we can divide both sides of the equation by 3⁄5, which is the same as multiplying both sides by its reciprocal, 5⁄3. This cancels out the fraction on the left side, leaving us with n = 6 × 5⁄3. Multiplying 6 by 5 gives us 30, and dividing that by 3 gives us a final answer of n = 10.

Holly has $462 in her bank account and takes out $15 each week but does not put any back in. Write an equation/expression to represent the amount of money she has in her bank account.
Answer:
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.
Step-by-step explanation:
Given that,
Holly has $462 in her bank account and takes out $15 each week but does not put any back in.
She takes out $15 on first week.
The remaining amount of her bank account is =$(462-15)
=$(462 - 1×15)
If she withdraws $15 on second week.
The remaining amount of her bank account is =$(462-15-15)
=$(462 - 2×15)
Similarly after third the amount in her account is =$(462 - 3×15)
From the above it is cleared that
The amount in her account after t week is
=$(462 - t×15)
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.

Answer:
A tiny but horrible alien is standing at the top of the Eiffel Tower (which is 324 meters tall) and threatening to destroy the city of Paris! A Men In Black agent is standing at ground level, 54 meters across the Eiffel square, aiming his laser gun at the alien. At what angle, in degrees, should the agent shoot his laser gun? Round your final answer to the nearest tenth
The agent shoot his laser gun at 80.5 degree.
Step-by-step explanation:
Given:
Height at which the horrible alien is standing = 324 m
Distance from the (tower) where the agent is = 54 m
According to the question:
Men In Black agent is aiming his laser gun to shoot the horrible alien.
Let the angle at which the agent shoot his gun be " Ф "
As from the situated depicted we can draw a right angled triangle.
Using trigonometric ratios:
tan (Ф) = opposite/ adjacent
In triangle OPQ .
The adjacent side = 54 m
The opposite side = 324 m
⇒ Plugging the values.
⇒ [tex]tan(\phi) = \frac{opposite}{hypotenuse}[/tex]
⇒ [tex]tan(\phi) = \frac{324}{54}[/tex]
⇒ [tex](\phi) = tan^-^1(\frac{324}{54})[/tex]
⇒ [tex]\phi=80.53[/tex]
Nearest tenth it is 80.5 degrees.
So,
Men In Black must shoot the laser gun at an angle of 80.5 degrees.
Final answer:
The Men In Black agent should shoot his laser gun at an approximate angle of 30.8 degrees to hit the alien at the top of the Eiffel Tower, after correcting the typos in the question.
Explanation:
To find the angle at which the Men In Black agent should aim his laser gun to hit the alien on top of the Eiffel Tower, we must solve a right triangle problem. The height of the Eiffel Tower is given as 324 meters, not 324324324 as stated in the question, which is likely a typo, and the horizontal distance (base of the triangle) from the agent to the base of the Eiffel Tower is 545 meters, not 545454 as stated, which seems to be another typo.
We use the tan inverse function (arctan) to calculate the angle. The angle θ is found using the formula:
θ = arctan(opposite/adjacent)
If h is the height of the tower and d is the distance across the ground, the angle θ equals:
θ = arctan(h/d)
Plugging in our values:
θ = arctan(324/545) ≈ arctan(0.5945)
Now we find the arctan of 0.5945 using a calculator:
θ ≈ 30.8 degrees
Therefore, the agent should shoot his laser gun at an angle of approximately 30.8 degrees.

Ronja answer to the nearest whole number percent
Answer: 32%
Step-by-step explanation:
The total number of students that signed up for chemistry and algebra
two is 386.
Let x represent the number of students that signed up for both chemistry and algebra two
If 209 students signed up for algebra two, then the number of students that signed up for algebra two only is
209 - x
If 300 need to have signed up for chemistry, then the number of students that need to have signed up for chemistry only is 300 - x
Therefore,
x + 209 - x + 300 - x = 386
- x + 509 = 386
x = 509 - 386
x = 123
If 123 students would be signed up for both courses, then the probability that a student chosen at random from the 386 will be signed up for both of the courses is

height for 4 possible volumes
Diameter 10 cm
Radius
Area of Base
Height
Volume
Cylinder A
Cylinder B
Cylinder
Cylinder D
How do you know your answers are reasonable?
Answer:
See below.
Step-by-step explanation:
PROBLEM A
The formula for the volume of a cylinder is
V = πr²h, where πr² is the area of the base.
V = area of base x height
Choose any four numbers that are less than 10 for the height.Then, substitute into the formula and isolate "r". 10 = πr²hDouble "r" to find the diameter.The area of the base is found (bolded) while you solve πr².*I will use the calculator button for pi (π)
Cylinder A: h = 1
10 = πr²h
10 = πr²(1)
10 = πr² Area of the base is 10m².
r = √ (10/π)
r = 1.78 Radius is 1.78m.
d = 2r = 1.78*2 = 3.56 Diameter is 3.56m.
Cylinder B: h = 2
10 = πr²h
10 = πr²(2)
5 = πr² Area of the base is 5m².
r = √ (5/π)
r = 1.26 Radius is 1.26m.
d = 2r = 1.26*2 = 2.52 Diameter is 2.52m.
Cylinder C: h = 4
10 = πr²h
10 = πr²(4)
2.5 = πr² Area of the base is 2.5m².
r = √ (2.5/π)
r = 0.89 Radius is 0.89m.
d = 2r = 0.89*2 = 1.78 Diameter is 1.78m.
Cylinder D: h = 5
10 = πr²h
10 = πr²(5)
2 = πr² Area of the base is 2m².
r = √ (2/π)
r = 0.80 Radius is 0.8m.
d = 2r = 0.80*2 = 1.6 Diameter is 1.6m.
The answers are reasonable if the answer is close to 10 when you substitute the rounded numbers back into the formula and solve.
There are infinite possibilities because any numbers when used in the formula equates to 10 are possible. The height/radius can be any decimal number, which would make the other dimensions change.
PROBLEM B
Follow similar steps if you know the diameter of a cylinder. Use the same formula V = πr²h.
We need the radius, which is half the diameter. r = d/2 = 10/2 = 5
Choose a random number for volume that divides easily by 25.Substitute "V" and "r²" (r² = 25).Isolate "h".The area of the base is 78.54 cm² every time (A = πr²).Cylinder A: V = 100
100 = π25h
4 = πh
h = 1.27 The height is 1.27m.
Cylinder B: V = 200
200 = π25h
8 = πh
h = 2.55 The height is 2.55m.
Cylinder C: V = 75
75 = π25h
3 = πh
h = 0.95 The height is 0.95m.
Cylinder D: V = 125
125 = π25h
5 = πh
h = 1.59 The height is 1.59m.
The answers are reasonable if I can substitute two rounded values into the formula and get a number close to the third. The height is also a decimal number which occurs because of pi.
Bruce is going to call one person from his contacts at random. He has 35 total contacts. 15 of those contacts are from his neighborhood. What is the probability he calls a person not from his neighborhood? Write your answer as a simplified fraction .
Answer:
do 35 divided by 15 then just put that into fraction form
Step-by-step explanation:
Answer:
two fifths is the answer because you would divide 15 by 35 to get .4 which is two fifths.

Type the expression that results from the following series of steps: Start with x , add 3 , then times by 6
Answer:
6(x + 3), or expanded: 6x + 18
Step-by-step explanation:
We start with x.
"Add 3" means + 3, so we have: x + 3
"Then times by 6" means multiply by 6, or * 6, so we have 6 * (x + 3)
Thus the expression is 6(x + 3), or expanded: 6x + 18
Hope this helps!
Answer:
6(x + 3)
Step-by-step explanation:
Add 3:
x + 3
Times 6:
6(x + 3)
3(2x - 1) =

HOPE I HELPEDPLZZ MARK AS BRAINLIEST !!!To start a board game,the player who rolls two sixes gets to go first. What is the probability that a player will roll two
number cubes and get two sixes?
) Intro
Done
There is a 1/36 or a ~2.8% chance that a player will roll two sixes. Because the dice is cubed, the player will have a 1/6 probability of rolling a six one time. Because the player needs to get six 2 times in a row, you would simply need to multiply 1/6 by itself twice(1/6•1/6 or 1/6^2) which equals 1/36.
What is the seventh term of the geometric sequence with a first term of 729 and a common ratio of ?
Given:
Given that the first term of the geometric sequence is 729.
The common ratio is [tex]\frac{1}{3}[/tex]
We need to determine the seventh term of the sequence.
Seventh term:
The seventh term of the sequence can be determined using the formula,
[tex]a_n=a_1(r)^{n-1}[/tex]
To find the seventh term, let us substitute n = 7 in the above formula, we get;
[tex]a_7=a_1(r)^{6}[/tex]
Now, substituting [tex]a_1= 729[/tex] and [tex]r=\frac{1}{3}[/tex], we get;
[tex]a_7=729(\frac{1}{3})^{6}[/tex]
[tex]a_7=729(\frac{1}{729})[/tex]
[tex]a_7=1[/tex]
Thus, the seventh term of the geometric sequence is 1.
