Answer:
3 kg = 105.82 ounces
Step-by-step explanation:
We have,
1 ounce = 28.35 g
and
1 kg = 2.21 lb
If we want to the value of 3 kg to ounces. The direct relation between kilogram to ounce is as follows :
1 kg = 35.274 ounces
It means,
3 kg = 105.82 ounces
So, the value of 3 kg is equal to 105.82 ounces.
Answer:
-(7x + 4)(3x - 2)

Average (mean) = (sum of all the data) / (# of data)
sum of all the data = (average)(# of data)
Thus for 100 students with an average of 93,
sum of all data = (93)(100) = 9300
and for 300 students with an average of 75,
sum of all data = (75)(300) = 22500
Therefore you would expect the overall average to be
(9300 + 22500) / (100 + 300) = 79.5 %
Now if there are x # of advanced students and y # of regular students, then
x + y = 90 (total # of students) and 93x + 75y = 87(x + y) (overall average)
The second equation can be simplified to x - 2y = 0
Subtracting the two equations yields
x = 60 and y = 90
Therefore you would need 60 advanced and 30 regular students.
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
