Answer:
Jeff got 20 answers right.
Step-by-step explanation:
The maximum number of points Jeff can get is 100. (25 * 4) However, for each question he gets wrong, he's actually losing 6 points because he doesn't get the four points for getting right, and has the additional -2 points for getting it wrong. Since he only got a score of 70, that means he lost 30 points.
30/6 = 5. So he missed 5 question and got 20 question right.
We know that
360°/12 hour----------> 30°/hour
that means
1 hour ----------> represent 30° in t<span>he clock hands
</span>so
150°+2 hour---------> 150°+2*30°-------> 150°+60°------> 210°
the answer is
the angle measure of the hands of the clock when basketball practice starts could be 210°
1. Answer is 4.5 km / hr.
... because you divide the time but the distance so for this question you divide 22.5 by 5 and that's your answer. do the same for every question! hope this helps.
