Not really sure whats up with that inequality but she can't, if she has to spend 1.5 hours in a lab that leaves her with 5 hours. 5/4 is 1.25, so no, she can only spend 1.25 hours with each student.
Answer:
26.50
Step-by-step explanation:
First we need to calculate the sales tax
25 * 6%
Changing to decimal from
25 * .06
1.50
Then we add the tax to the cost of the shirt
25+1.50
26.50
We owe 26.50
The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.
