Answer:
5 sec
Step-by-step explanation:
Hit the water, means h = 0
Solve -16t^2 + 68t +60 =0
4t^2 - 17t - 15 = 0
(4t + 3)(t - 5) = 0
so t = 5 sec
The nonpermissible replacement of the variable in a certain expression is the value of x that will make the denominator of the expression zero. In this certain given,
6x + 3 ≠ 0
Solving for x,
x ≠ -1/2
Thus, the answer is -1/2.
#11 is c:$27. im not sure about #10
It's 96%
816/850 = 0.96, which is 96%
Hope I helped! ( Smiles )
In general, this would be a ratio. However, if the ratio is the number of items with specific characteristic to the total number of elements, then this would be a probability. The dividend is the numerator, and the divisor is the denominator. For example, if there are 5 white balls out of 6 balls, the probability of getting a white ball would be 5/6. The dividend here is 5.
