Factored form: c(c-8) = 0
Then apparently, c = 0 or c = 8
Answer:
if you need the formula, it is pq/2
Step-by-step explanation:
the "p" is a diagonal of the rhombus
the "q" is the other diagonal of the rhombus
you multiply p and q
the you divide that number by 2
then, you have found the area
Answer:
48
Step-by-step explanation:
The fraction who picked apples is the rest of the students:
1 - 5/8 = 3/8
of them.
So the number who picked apples relative to the number who picked bananas is ...
apples/bananas = (3/8)/(5/8) = 3/5
Multiplying this by the number who picked bananas gives the number who picked apples:
apples = bananas · 3/5 = 80·3/5 = 48
48 students picked apples.
____
<em>Alternate solution</em>
Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...
80/(80 +a) = 5/8
640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify
240 = 5a . . . . . . . . . . . subtract 400
240/5 = a = 48 . . . . . . divide by 5
48 students picked apples.
Thank you for posting your question here at brainly. We find the answer by using mean (or average) when we use mean we add both together and divide by how many numbers we add. So 50 + 40 = 90. 90 / 2 = 45. So 45 is the average speed he traveled at the whole trip. 45 is your answer
