3x/8+1=9/8
3x/8+1(8/8)=9/8
3x/8+8/8=9/8
3x+8=9
3x=1
x=1/3
Answer:
1.4 times as high
Step-by-step explanation:
Now here we have to compare the both final velocities by using the formula independent of time. As we know,
2aS = V(f)2 - V(i)2
Both balls are dropped from certain height, so V(i) = 0 m/s for both balls
So, 2aS = V(f)2 for both balls.
Now if we compare both velocities
Equation for first ball
2aS(1) = V(1)2
Equation for second ball
2aS(2) = V(2)2
Comparing both equations
2aS(1)/2aS(2) = V(1)2/V(2)2
as we now S(1) = 5m and S(2) = 10m, also acceleration a = g, because acceleration due to gravity is acting on the balls. So,
2(9.8) x 5/2(9.8) x 10 = V(1)2/V(2)2
after simplifying,
1/2 = V(1)2/V(2)2
V(2)^2 = 2V(1)^2
By taking square root on both sides,
V(2) = 1.4V(1)
Answer:
In order, top to bottom: y = 2, 1, 0, 1, 2
Step-by-step explanation:
The rule is essentially saying that in order to change x into y, you find the absolute value of x. The absolute value is the integer value without a negative. Therefore, all that's needed is to find the positive version of each of the x values.
Equation: 49 = 150 - 150(x)
Steps to Solve:
49 = 150 - 150(x)
-101 = -150x
x = 0.6733 or 67.33%
The sterling and diamond bracelet is approximately 67.33% off.
Hope this helps!! :)
The answer is 9.2, because when the number behind the number being rounded is 5 or above, you round up. if the number was 9.14, it would be rounded down to 9.1 :)
