Answer: . x 10^5 miles from the earth. How long does it take light to from a source on earth to reach a reflector on the moon and then return to earth? The speed of light is 3.0 x 10^8 m/s. ... sec. to give us our final answer of 1.28 seconds (the time required for light to travel 2.4 x 105 miles). and the fastest spaceship goes 153,454 miles per hour
Step-by-step explanation:
The number of hours that should be taken to fly to the moon from Earth is 7 hours.
Given that
Distance between earth and moon is \(2.4 \times 10^5\ miles\)The speed is \(3.6 \times 10^4\ miles\ per\ hour\)Now we know that
\(Time = \frac{Distance}{Speed} \\\\= \frac{2.4 \times 10^5 }{3.6 \times 10^4} \\\\= \frac{240}{36}\)
= 6.66 hours
= 7 hours
Therefore we can conclude that The number of hours that should be taken to fly to the moon from Earth is 7 hours.

What is the translation from
a) shape X to shape Z?
b) shape Z to shape X?
The translation form of each shape is given as follows:
a) X to Z: (x, y) -> (x + 5, y + 2).
b) Z to X: (x, y) -> (x - 5, y - 2).
What are the translation rules?The four translation rules are defined as follows:
Left a units: x -> x - a.Right a units: x -> x + a.Up a units: y -> y + a.Down a units: y -> y - a.For the composition of translations, we add the coordinates, hence:
-2 + 7 = 5.5 - 3 = 2.Hence the rule from X to Z is given as follows:
(x, y) -> (x + 5, y + 2).
From Z to X, we have the inverse rule, hence:
(x, y) -> (x - 5, y - 2).

Step-by-step explanation:
Step 1: Define
Identify systems
y = 3x + 5
y = 4x
Step 2: Solve
If we compare the 2 lines, we can see that they both have a different slope. If they had the same slope but different y-intercepts, then they would be parallel and have no solution. We can also see that the 2 lines aren't the same. If they were, then they would have infinite solutions.
∴ the systems should have only one solution.

Diane sells boxes of cookies for each. Manuel sells boxes of cookies for each. Each of them sold the same dollar amount. It was the smallest dollar amount for which this was possible.
Part A : How many boxes did Daiane sell?
Part B : How many boxes did Manuel Sell?
Part C : What was the dollar amount each of them sold?
Part A: Daiane was known to have sold 5 boxes.
Part B: Manuel as known to have sold sold 4 boxes.
Part C: Daiane sold a total of = $40 while Manuel sold a total of $40.
What are the cookies?From the question, take the number of boxes Daiane sold as 'x'.
Note that she sells each box for $8, Hence the total dollar amount she sold is 8x.
Also take the number of boxes Manuel sold is 'y' because he sells each box for $10, so the total dollar amount he sold is = 10y.
Since the total dollar amount Diane sold is equal to the total dollar amount Manuel sold. the equation will bw:
8x = 10y
Then one can simplify the equation, by dividing both sides by the greatest common divisor (GCD) of 8 and 10, that is 2:
(8x)/2 = (10y)/2
4x = 5y
So the possible solution is that
x = 5
y = 4.
So one can say that:
Part A: Daiane sold 5 boxes.
Part B: Manuel sold 4 boxes.
Part C: Daiane sold a total of :
= 8 x 5

What is a fraction?Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.
Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.
Given that,
A fraction number 1/2
In decimal form = 0.5
Closest fraction number = ?
Most closest number is that number from which we subtract the given number and the magnitude of result we get is very less,
Lets take, A fraction 1/6
In decimal form it can written as, 0.167
Difference 1 = 0.5 - 0.167
= 0.333
Similarly, For numbers 3/8, 3/4, -1/2
Difference 2 = 0.5 - 0.375 = 0.125
Difference 3 = 0.5 - 0.75 = -0.25
Difference 4 = 0.5 - (-0.5) = 1.0
It can be seen that,
Magnitude of difference in case of 3/8 is very less

Central angle ∠C and circumscribed angle ∠S intersect the same arc, so the angles are supplementary. Central angle ∠C and inscribed angle ∠R intersect the same arc, so m∠R is half the measure of central angle ∠C.
What makes the angles supplementary?Central angles are angles that have their vertex at the center of the circle. Circumscribed angles are angles that are formed by two tangents to a circle that intersect at a point outside the circle. Inscribed angles are angles that are formed by two chords in a circle that intersect at a point inside the circle.
The measures of central angles and circumscribed angles are always supplementary, which means that their measures add up to 180 degrees. Inscribed angles, on the other hand, are always half the measure of the central angle that intersects the same arc.
In the diagram, central angle ∠C and circumscribed angle ∠S intersect the same arc, so they are supplementary. Central angle ∠C and inscribed angle ∠R also intersect the same arc, so m∠R is half the measure of central angle ∠C.

Answer:
677.30
Step-by-step explanation:
5, round up to 3
Rounding off 677.25 to the nearest tenths gives 677.20.
What is rounding off?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done. An integer containing one or more "0"s at the end in a specific base is said to be round. In this way, 590 is more rounded than 592 but less rounded than 600. A round number is frequently understood to stand for a value or values close to the nominal value expressed in both formal and informal language.So, 677.25 to the nearest tenth:
Since, after the decimal, the tenth place has 2, and due to this after rounding off, the value will be:677.25 ⇒ 677.20Therefore, rounding off 677.25 to the nearest tenths gives 677.20.

"Q: Use inductive reasoning to determine the units digit of the number 355. Please give detailed descriptions on how you would solve this problem."
Bob said he could use his high-precision calculator to find the exact value of 355, and he would know all the digits. He then showed Ali, the tutor his calculator display 3^55 = 1744492 1100912017 9071170507. The tutor Ali at the ASC said that was the incorrect approach to this problem.
(a) Why did Ali say it was an incorrect approach?
(b) What is the correct approach to get the answer of units digit =7? Be specific with how you solved this question.
(c) Give an example of how you used inductive reasoning in your life. Are you certain about the conclusion? Hint: review the characteristics of inductive reasoning.
Therefore the solution is used 3⁵⁵ instead of 3⁵. to look at the units digit of the base number and the exponent.
What does "inductive reasoning" mean?
The process of inductive reasoning involves moving from the particular to the general in order to arrive at conclusions. Deductive reasoning, where you move from general information to specific conclusions, is typically contrasted with it. Bottom-up reasoning and inductive logic are other names for inductive reasoning.
To determine the units digit of a number using inductive reasoning, can use the following steps:
Find the units digit of 3¹ = 3
Find the units digit of 3² = 9
Find the units digit of 3³ = 27
Find the units digit of 3⁴ = 81
Find the units digit of 3⁵ = 243
Since we are looking for the units digit of 355, we can use inductive reasoning to find that it is equal to the units digit of 3^5 which is 3 1.
A .
Ali said that Bob’s approach was incorrect because he used 3⁵⁵instead of 3⁵.
B .Correct approach To find the units digit of a number raised to a power, you only need to look at the units digit of the base number and the exponent.
C .
In this case, 3⁵ = 243. The units digit of 243 is 3. Therefore, the units digit of 3⁵⁵ is also 3.An example of how I used inductive reasoning in my life is when I was trying to figure out why my car wouldn’t start. I noticed that it only happened when it was cold outside. After several times of this happening, I concluded that it must be something with the battery since cold weather can affect battery performance. I took it to a mechanic who confirmed that the battery was indeed the problem. Inductive reasoning involves making generalizations based on specific observations or evidence. While it can be useful in many situations, it’s important to remember that it doesn’t always lead to correct conclusions.

The vertices of the feasible region are (0 , 15/2) , (21/11 , 19/11) and (6 , 0)
Given, the constraints of a problem
2x+3y≥12
5x+2y≥15
x ≥ 0
y ≥ 0
On solving the equations, we get
( 2x + 3y ≥ 12 ) × 2

4x + 6y ≥ 24
15x + 6y ≥ 45
