The answer is 0.52 s
The function is t = 0.005x² + 0.002x
x = 10
Substitute x into the function:
t = 0.005 * 10² + 0.002 * 10
t = 0.005 * 100 + 0.02
t = 0.5 + 0.02
t = 0.52 s
Answer:
90 balls
Step-by-step explanation:
Set up proportion
36/x = 40/100
Cross multiply: 40x=3600
Solve for x
x=90
To check work:
40 percent of 90 would be 36
90(0.4)=36
Answer:
Step-by-step explanation:
504 = 2 x 2 x 2 x 3 x 3 x 7
24 = 2 x 2 x 2 x 3
The answer is C I just finished taking the test
In some cases, there are better solutions than factoring. Consider, for example the quadratic equation x^2+x+1, which is much easier to solve using the quadratic formula than by factoring.
