Answer: choice B is true.
Step-by-step explanation:
We are asked to find which value is similar to the value of the expression:
30% of 81.
We know that 30% of 81 could also be represented mathematically as:
30%×81=
which could also be written as:
choice A:
=
Which is not similar to equation (1).
Hence choice A is not similar.
Choice B:
This expression is similar to equation (1).
Hence choice B is true.
Choice C:
Which is not similar to equation (1).
Hence, choice C is not true.
Choice D:
=
Which is not similar to equation (1).
Hence, choice D is not true.
Choice E:
Which is not similar to equation (1).
choice D is not true.
Would you like me to help walk you through this with you figuring out the work?
Or would you prefer just an answer in math form with me explaining it along the way?
<span>h(t) = 80t – 16t^2
When you are on the ground we have zero height, h(t) = 0. This is saying that at some amount of time we will call t, the object will hit the ground. Now we solve for t to get that time
so we sub h(t) for 0.
0=80t-16t^2 move the -16t^2 to the other side
16t^2=80t divide both sides by t
16t=80 divide both sides by 16
t=5
Now... it is important to realize that there are going to be 2 answers to this equation as you have a t^2. The other answer is 0. Obviously, unless the object started on the ground, the time to hit the ground is not 0 and that answer is ruled out.
