Answer:
The same ratio indicates that there is a proportional relationship between y and x.
Step-by-step explanation:
We know when y varies directly with x, the equation is
y ∝ x
Here,
k is the constant of proportionality.
The ratio y/x indicates that k is a constant of proportionality.
Thus, the same ratio indicates that there is a proportional relationship between y and x.
When x increases, y increases, and when y decreases, x also decreases.
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
Hence, the required expression is (48/b).
Answer:
$68.44 for each additional belt
Step-by-step explanation:
The cost and revenue functions are:
The profit function, P(x), is given by subtracting the cost function from the revenue function.
The derivate of the profit function gives us the rate at which profit changes:
For x = 484, the rate of change is:
Profit is increasing by $68.44 for each additional belt
