Answer: D. 2
Step-by-step explanation:
-3t + 6 = 0
1. Subtract 6 from each side
-3t + 6 - 6 = 0 - 6
-3t = -6
2. Divide each side by -3 to isolate t and get the answer to the equation
-3t/-3 = -6/-3
t = 2
You can check your answer by plugging your calculated value back into the equation and evaluating to find that 0 = 0.
The orbit of the Moon around the Earth is an ellipse with Earth at one focus. If the length of the major axis of the orbit is 477,736 miles and the length of the minor axis is 477,078 miles, find the minimum and maximum distances from Earth to the Moon. Round to the nearest whole number.
Answer:
226,335
251,401
Step-by-step explanation:
SKR SKR BOW
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

I need to know the answer to this
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.

The current temperature is 30°C. Over the next eight hours the temperature decreases and then increases, returning back to 30°C. if the temperature initially decrease by 13°C, how much did it subsequently increase?
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:
30°C - 13°C = 17°CIf 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.

m∠ABC=(6x+8)° and m∠DEF=(12x-8)°.
If ∠ABC and ∠DEF are supplementary,what
is the measure of each angle?
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:
(6x + 8) + (12x - 8) = 180Combine like terms.
18x = 180Divide both sides by 18.
x = 10Find the measure of each angle by substituting 10 for x into both expressions for the angles.
m∠ABC = (6x + 8)°
6(10) + 8 = 68°m∠DEF = (12x - 8)°
12(10) - 8 = 112°→ (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°

a carton of ice cream sold for $2.20 was on sale for 45% off. what was the original price of the ice cream?
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
What is the discount price?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
