Answer:
140
Step-by-step explanation:
5%/100 = 7/?
7 times 100 = 700
700 divided by 5 = 140 coins
We conclude that the interval in which the function decreases is (1.5, 3]
<h3>
In which interval is the ball's height decreasing?</h3>
The ball is decreasing when the graph, reading from left to right, is going downwards.
Particularly, in this parabola that opens downwards, the graph will decrease after the vertex.
And we can see that the vertex is at x = 1.5
And we also see that the graph of the function ends at x = 3.
Then we conclude that the interval in which the function decreases is (1.5, 3]

Answer:
2304 quarts
Step-by-step explanation:
An ice cream factory makes 320 quarts of ice cream in 5 hours. How many quarts of ice cream could be made in 36 hours?
From the above question
5 hours = 320 quarts
36 hours = x quarts
Cross Multiply
5 hours × x quarts = 320 quarts × 36 hours
x quarts = 320 quarts × 36 hours/5 hours
x quarts = 2304 quarts
Therefore, 2304 quarts of ice cream could be made in 36 hours.
Constant of Variation has this formula for Direct Variation.
y = kx
Where y = cost in dollars; x = length in meters; k = constant
We will use the formula for direct variation because the problem states that the cost varies directly to the length.
In the problem we need to get the constant of variation.
k = y/x
k = $4500 / 200 meter
k = $22.50 cost per meter.
A.) The equation relating C and s is:
k = C/s
* i just substituted C for y and s for x.
B.) The constant of variation represents the additional cost that the company will pay for every meter in length they add. which is $22.50 per meter.
C.) y = kx ; substitute C and s to y and x respectively;
C = ks
C = $22.50 * 700 m
C = $15,750
