360=24%0f x
360=24/100*x
360*100=24x
36000/24=x
therefore, x=1500......
Answer:
On second day: 500 cm^3
On third day: 250 cm^3
Step-by-step explanation:
Let x be the initial amount of helium gas in the balloon.
As it is mentioned in the question that the balloon loses half of it's gas in one day. So after one day the gas will be half of the current volume. And to calculate the volume of gas the next day, the reduced volume will be divided by two.
So,
x = 1000 cm^3
Volume on second day,
x1 = 1000/2
=> 500 cm^3
Volume of gas on third day
x2 = x1/2
=> 500/2
=> 250 cm^3
Complete the square of y^2 + 10y to answer this question.
x=y^2 + 10y + 22 becomes x = <em>y^2 + 10y + 100</em> - 100 + 22, or
x = (y+10)^2 - 78
Comparing this result to the generic form x = a(y-k)^2 + h, we see that
h = -78 and k = -10.
Then the vertex of this parabola is at (-78, -10).
Answer:
B. 90
Step-by-step explanation:
Since the two angles are supplementary, this means they both are on a flat line (180 degrees)
Since both A and B add up to 180, we take that number and subtract A (90) to get our answer: 90 degrees
Answer:
The angles are supplementary. X = 31
Step-by-step explanation:
The angles sum to equal 180 degrees, menaing they are supplementary. Add the degrees of each side 3x + 25 + 2x = 180 and solve for x. X should equal 31.
