Answer:
Should be 82% sorry if I'm wrong have a amazing day
Answer:
I believe 0.75 is the answer. Here is my work:
Step-by-step explanation:
1. 250 divided by 5 = 50 (this is to get 1/5 of 250)
2. 250 divided by 2 (because 1/2 is equivalent to 50% of the overall number) = 125
3. 50 + 125 = 175
4. 250-175 = 75
5. 75 can be converted to 0.75 as a decimal by moving 2 digits over.
Therefore, out of the 250 seventh grade students, 0.75 are in other electives.
Also, I'm in 7th grade so this is my work, I'm sure there are other ways of solving this, too. Please do not add this answer if you don't believe I'm right.
Thanks for your time, and have a nice day! : )
Answer: 0.75
Answer:
3.15 seconds is the answer.
<u>Explanation</u>
when the ball touches the ground, h =0
hence,
0=255-21t-16t²
16t²+21t-225=0
here a=16 ,b=21, c= -225

time cannot be negative, hence t = -4.46 can be avoided
The ball takes 3.15 seconds to hit the ground.
16 6th graders went on the field trip and 16 5th graders went on the field trip so that makes 32 students all together which means 32% of the students went on the field trip
