Answer: 127</h3>
=================================================
Explanation:
The phrasing "2/3 of 4/5 of his 2nd exam on his 3rd test" is a bit clunky in my opinion. It seems more complicated than it has to be.
The student got 80 on the second exam. 4/5 of this is (4/5)*80 = 0.8*80 = 64. Then we take 2/3 of this to get (2/3)*64 = 42.667 approximately. If we assume only whole number scores are given, then this would round to 43.
Let x be the score on the fourth exam. Since 5 points of extra credit are given, the student actually got x+5 points on this exam.
So we have these scores
- first exam = 70
- second exam = 80
- third exam = 43
- fourth exam = x+5
Adding up these scores and dividing by 4 will get us the average
(sum of scores)/(number of scores) = average
(70+80+43+x+5)/4 = 80
(x+198)/4 = 80
x+198 = 4*80
x+198 = 320
x = 320 - 198
x = 122
So the student got a score of x+5 = 122+5 = 127 on the fourth exam.
Omg ur keeping me awake with these notifications!! LOL :-D. JK
Arc RQ is a [minor arc] only because it is less than half the circle, which is 180 [PQ]
** remember that 180° always = half a circle
7.5g of butter
So for 8 pancakes 5g of butter is needed.
So to make one pancake we have to divide 5 by.
5/8 = 0.625
And then you times 0.625 by 12 to find out how much butter is needed for 12 pancakes
So the answer is
7.5g of butter
