Answer and explanation:
Farmer's number of apples = 96 apples
Given that Farmer needs to bag the apples so that there are at least 4 apples in each bag(not less than 4 apples in each bag) and not more than 10 apples in each bag
And also all apples in each bag are equal
We need to find the numbers between 4 and 10(including 4 and 10) that can divide 96 without a remainder
4 can divide 96= 24
5 cannot divide 96 without remainder
6 can divide 96 =16
7 cannot divide 96 without remainder
8 can divide 96=12
9 cannot divide 96 without remainder
10 cannot divide 96 without remainder
From the above we see that the factors of 96 = 4, 6, 8 between 4 and 10
4 apples = 24 bags
6 apples = 16 bags
8 apples = 12 bags
Therefore, there can be 3 possible ways of having equal number of apples in each bag between 4 and 10 apples
1.
c=cows
b=chicens
c+b=28
chicen has 2 legs
cow has 4 legs
4c+2b=64
c+b=28
4c+2b=64
multiply first equaiton by -2 and add to second
-2c-2b=-56
4c+2b=64 +
2c+0b=8
2c=8
divide 2
c=4
sub
c+b=28
4+b=28
minus 4
b=24
4 cows and 24 chicens
2.
t=twelve oz
s=sixteen oz
t+s=20
12t+16s=300
find t
multiply first equation by -16
-16t-16s=-320
add to first equation
-16t-16s=-320
12t+16s=300 +
-4t+0s=-20
-4t=-20
divide -4
t=5
five 12 oz bottles
1. 4 cows, 24 chicen
2. 5 twelve oz bottles
Answer:
2.57
Step-by-step explanation:
10*10*10 = 1000
2570/1000 = 2.57
