Answer: 21
Step-by-step explanation:
Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.
Since, 108 = 2 x 2 x 3 x 3 x 3
84 = 2 x 2 x 3 x 7
60 = 2 x 2 x 3 x 5
HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]
= 12
Greatest number of plants in each row = 12
Number of rows for mango =
Number of rows for guava =
Number of rows for sapota =
Total rows = 9+7+5= 21
Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted = 21
Step-by-step explanation:
-5x + 8y = 8
8y = 5x + 8
y = (5/8)x + 1
So it has a slope of 5/8 and crosses the y axis at (0,1)
For a string length of 1 there are 2 possible strings (2^1)
for a string length of 2 there are 4 possible strings (2^2)
for a string length of 3 there are 8 possible strings (2^3)
So, for string length of 7 there are 128 possible strings (2^7)
