Given : x and y are natural numbers . As (7x+1) is divisible by y and (8x+3) is also divisible by y.
To find: y
Solution: Since (7 x+1) is divisible by y and (8 x+3) is also divisible by y.
1.As x,y are natural numbers, So
→8 x+3>7 x+1
→8 x+3=7 x+1+k y where k is any natural number.-------(1)[reason: 4 is divisible by 2 and 6 is also divisible by 2, so 6=4+2k]
→8 x-7 x+3-1=k y
→k y= x+2
If k=1, then y=x+2.
So value of y is x+2.As y≠1, so for different values of x there are different values of y. so x=1,we get y=3, as this is linear equation in one variable.
→y is an odd natural number,=[3,5,7,9,.....]≠1
Sin(theta) = opposite/hypotenuse
Sin(41 deg) = 2.5/x
Xsin(41) = 2.5
X = 2.5/sin(41)
X = 3.8
Answer:
36 km
Step-by-step explanation:
By dividing 45 by 60 you make it into .75 per minute therefore by multiplying by 48 you get your answer which is 36 km
