The minimum distance from Earth to Moon is 226,332 miles

The maximum distance from Earth to Moon is 251,401 miles

What is an Ellipse?

An ellipse is created by a plane intersecting a cone at the angle of its base

All ellipses have two foci, a center, and a major and minor axis

The sum of the distances from any point on the ellipse to the two foci gives a constant value

The value of eccentricity for all ellipses is less than one

The standard for of equation of ellipse is

( x²/a² ) + ( y²/b² ) = 1

where a > b

The length of the major axis = 2a

The length of the minor axis = 2b

The coordinates of foci = ( ±c , 0 )

where c² = a² - b²

Given data ,

The orbit of the Moon around the Earth is an ellipse with Earth at one focus

The length of the major axis 2a = 477,736 miles

The length of the minor axis 2b = 477,078 miles

Now , the value of a = 238,868 miles

The value of b = 238,539

Now , the maximum distance from earth to moon is = a + c

The minimum distance from earth to moon is = a - c

The value of the foci is given by c² = a² - b²

Substituting the values in the equation , we get

c² = ( 238,868 )² - ( 238,539 )²

c² = 157066903

Taking square roots on both sides , we get

c = 12532.63 miles

Now , maximum distance from earth to moon is = a + c

Maximum distance = 238,868 + 12535.63

                                = 251,400.63 miles

                                ≈ 251,401 miles

Now , The minimum distance from earth to moon is = a - c

Minimum distance = 238,868 - 12535.63

                               = 226,332.37 miles

                               ≈ 226,332 miles

Hence ,

The minimum distance from Earth to Moon is 226,332 miles

The maximum distance from Earth to Moon is 251,401 miles

Answer:

0.625

Step-by-step explanation:

To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.

Therefore, the answer would be 5/8, or 0.625.

To verify, we can use the other values given in your question.

10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.

You can do the same with the other ratios given.

15/24 simplified is 5/8, which, once again, is 0.625.

Thus, I can say with certainty that the answer is 0.625.

Answer:

13°C

Step-by-step explanation:

The number of hours that the temperature fluctuates is irrelevant to the problem.

This problem is asking how many degrees did the temperature increase in order to go back to 30°C after being decreased by 13°C.

Find the new temperature after it decreased:

If the temperature after decreasing is 17°C, it needs the same amount it was decreased by to go back to 30°C.

Therefore, the temperature subsequently increased by 13°C to go back to 30°C after being decreased by 13°C.

Answer:

It was originally sold at roughly $4.887

Step-by-step explanation:

1)  2.20/.45 ≈ 4.8

2) 4.8 x .45 = 2.16

3) 4.88 x .45 = 2.196

4) 4.887 x .45 = 2.19915

The original price of the ice cream is $4.8

Discounting a product means offering it at a lower price than the list price.

Given that, a carton of ice cream sold for $2.20 was on sale for 45% off.

Let the original price of the carton be x.

x*45% = 2.20

x = 2.20*100/45

x = 4.8

Hence, the original price of the ice cream is $4.8

-3t = -6

2. Divide each side by -3 to isolate t and get the answer to the equation

-3t/-3 = -6/-3

t = 2

Answer: 276

Step-by-step explanation:

multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.

Answer:

m∠ABC = 68°

m∠DEF = 112°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees (they form a straight line).

If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:

Combine like terms.

Divide both sides by 18.

Find the measure of each angle by substituting 10 for x into both expressions for the angles.

m∠ABC = (6x + 8)°

m∠DEF = (12x - 8)°

→ (6x + 8) + (12x - 8) = 180°

→ 6x + 8 + 12x - 8 = 180°

→ 18x = 180°

→ x = 180 ÷ 18

→ x = 10°

Now, we are given that m∠ABC = (6x+8) just subsitute the value of x in it .

→ m∠ABC = (6x + 8)

→ m∠ABC = (6 × 10 + 8)

→ m∠ABC = 60 + 8

→ m∠ABC = 68°

Similarly, subsitute the value of x in m∠DEF = (12x - 8)° we get :

→ m∠DEF = (12x - 8)°

→ m∠DEF = (12 × 10 - 8)

→ m∠DEF = 120 - 8

→ m∠DEF = 112°
