The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?
Answers
Answer: 3000 Kelvin
Step-by-step explanation
Let the surface temperature of the red giant star = x
Surface temperature of a white dwarf star = 4x
4x = 1.2 × 10^4 K
= 1.2 × 10,000 K
= 12,000 K
4x = 12,000 K
x = 12000 ÷ 4
= 3,000 K

Analiese,
The formula for volume of a cylinder is v=πr^2h
So first you plug in the info. you were given.
v=3.14x11^2x 18
Then, you simplify the equation.
v=3.14x121x18
v=3.14x2,178
v=6,839 cubic feet

Answer:
x is 23
Step-by-step explanation:
cause it is an 180 angle so 180-93=87
87 -18 =69
3x=69
x=23
Answer:
x=23Step-by-step explanation:
in order to find x
(3x+18)° + 93°=180°
⇒3x+18=180-93
⇒3x=180-93-18
x=69/3
x=23
and there we go X = 23

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

Answers
Answer:
3/5 1/10
Step-by-step explanation:
1/5 divided by 1/3 is 1/5 times 3 which is 3/5
1/2 divided by 5
= 1/2 divided by 5/1
=1/2 times 1/5
=1/10
Answer: 1) 3/5 2) 1/10
Step-by-step explanation:
1) 1/5 divided by 1/3
then you take the reciprocal so the equation is now 1/5 times 3/1
and you get an answer of 3/5
2) 1/2 divided 5/1 (you put the one under the 5 cuz it's a whole number)
Take the reciprocal of the second fraction and flip the numerator and denominator so you get 1/5.
Then, do 1/2 x 1/5 which equals 1/10.

Answers
Answer:
108 degrees
Step-by-step explanation:
By the Exterior Angle Theorem:
(2x + 1) + 63 = 5x -2
2x + 64 = 5x - 2
66 = 3x
22 = x
Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:
5(22) - 2
110 - 2
108
The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)

The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.
Answers
Answer:
1st 2nd and 3rd box
Step-by-step explanation:
1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)
2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)
3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin
4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.
