Part A:
x = 8
Part B:
64cm
Part C:
64cm
Part D:
yes
(1 h)/(11 qt) * (12 qt)/(1 barrel) * (120 barrels/pickup) * (1 day)/(24 h)
.. = 12*120/(11*24) day/pickup
.. = 5 5/11 days/pickup
120 barrels will be filled every 5 5/11 days. Some trips will be 5 days apart, some trips will be 6 days apart.
Because the average is 7.7, his total points are equal to 7.7*10=77.
Because 7*10<77<8*10, Luke cannot have scored 8 10s. We now seek to prove that he can score 7 tens.
This leaves him with three tests left, that sum to 7 marks. There are clearly many ways to arrange this - for example, 2, 3, and 3 on the first three tests, then ten on all seven other tests. As this shows that 7 10s works and we have proven that 8 10s does not work, 7 is the maximum amount of 10s Luke could have scored.
Sum = 2/8 + 3/8 = (2+3)/8 = 5/8 pounds
Difference = 3/8 - 2/8 = (3-2)/8 = 1/8 pounds
Answer:
the answer is (x+8)
Step-by-step explanation:
there are two answer for this question, since your answer doesn't have (x-5), then it should be (x+8). hope this helps!
