Answer: h = kAT^4/d²
Step-by-step explanation:
When two variables vary directly and increase or decrease in one variable causes a corresponding increase or decrease in the other variable. When they vary inversely, an increase in one variable causes a decrease in the other variable and vice versa
The rate at which a planet receives heat (h), varies directly with the fourth power of the sun's absolute temperature(T), directly with the surface area of the Sun(A), and inversely with the square of the distance from the Sun to the planet(d). By introducing a constant, k, the general equation would be
h = kAT^4/d²
The answer is the first one
Answer:
A, m < $69.43
Step-by-step explanation:
(Could be wrong, I'm just browsing through brainly and thought it looked easy)
I found the percentage of what they've raised by doing 552.5 * .12 (12 percent of 552.5)
This gave me 66.3
We now need to look for how much they need to raise, so you subtract 552.5 by 66.3 to get 486.2.
You need to find out how much each of the 7 members needs to raise to get 486.2, to do this divide 486.2 by 7 to get 69.45.
Ideally, they would raise just this amount and the correct answer would be an equal sign, but since that isn't an option and if they raised less than 69.45 individually they would fail, raising more than 69.45 would pass their goal. So A, more than 69.45 is the answer.
X^2+ y^2=109
x 2 + y2 = 109
Step 1: Add -y^2 to both sides.
x 2 + y2 + − y2 = 109 + − y2
x 2 = − y2 + 109
Step 2: Take square root.
x = − y2 + 109 or x = − − y2 + 109
Answer:
x = − y2 + 109 or x = − − y2 + 109 CALCULATE IT
Solve for Variable
x-7=1/3y^2
x − 7 = 1
3 y2
Step 1: Add 7 to both sides.
x − 7 + 7 = 1
3 y2 + 7
x = 1
3 y2 + 7
Answer:
x = 1
3 y2 + 7
