5600 can be simplified. Say you were to just take the two zeros off the end and you would have 56. Now divide 56 by 7 and you get 8. Add the zeros back to the 8 and your answer is 7 x 800. Hope this helps.
Step-by-step explanation:
Find w
V = lwh
V ÷ lh = w
V/lh = w
w = V/lh
Option → C
Count the total number of students who prefer fiction novels: In 9th grade there are 35, in 10th grade there are 52, so there are 87 students who prefer fictions. The proportion of 10th grade students out of these 87 students is 52/87=0.60 approximately.
N/4 less than or equal to 5
.57 I would assume but it really depends on how your scaling it
