1/2N+1/5P-6=?
hopefully that helps :)
Independent variable : the cows
Dependent variable : the weight of both cows
Answer:
Step-by-step explanation:
72 is the product of 8 and 9, so the number needs to be divisible by both 8 and 9.
The number 100 is divisible by 8 with a remainder of 4, so to make it have no remainder, we must add another 4 to the number: 104. We cannot have any other digit in the ones place (x) and have 10x be divisible by 8.
The 4-digit number must have a sum of digits that is divisible by 9 if it is to be divisible by 9. 104 has a sum of digits of 5, so we must have another digit of 4 to get a number divisible by 9. There is no other single digit that will do.
The number we're looking for is 4104 = 72·57. There are no other solutions.
Hey there!
Answer-
See Below.
Step by step explanation-
Let the number of 50 paise coins be x, then the number of 25 paise coins will be 4x.
The value of 50 paise coins is 50x paise and the value of 25 paise coins be 25(4x)=100x paise.
According to the giving condition,
∴The number of 50 paise coins is 40 and number of 25 paise coins is 4x=4(40)=160.
