Answer:
6 kg
Step-by-step explanation:
Given is weight of an object directly varies with the mass of the object .
Let the constant of proportionality be k
So,
Weight = K×(mass of the object)
For an object , weight = 45 N
mass = 9 kg
So , 45 = K×9
K = 5.
Now, for the other object ,
Weight = 30 N. K = 5 (as obtained above)
So, 30 = 5×(mass of the object)
mass of the object = 6 kg.
Let
x-----------> <span>the first number
y-----------> </span><span>the second number
we know that
x*y=x-----------> y=x/x----------> y=1
and x+y=y------> x=y-y---------> x=0
the answer is
</span> the first number is 0
the second number is 1<span>
</span>
Answer:
B. 75%
