Answer:
2.25 tons
Step-by-step explanation:
It is a conversion problem. The connection between ton and pound is in the following order:
1 pound = 0.0005 tons
By multiplying each side by 4500 we can easily find the answer of this problem:
4500 pounds = 2.25 tons
The graph is attached.
We first graph the point where his catch reached the surface, (35, 0). Since it travels upward at a constant rate, the graph will be linear. We also need to know where it starts (what depth it is at when he begins reeling it in). We can use the formula d=rt as a template for our function. d would be distance (in our case, depth), r is the rate (speed) and t is the amount of time.
To find how far the catch had to travel to reach the surface, we set up our equation as:
d = 0.1(35)
This will tell us how much distance it traveled in 35 seconds. 0.1(35)=3.5, so the catch started 3.5m under water. It then travels up at 0.1 m per second.
Answer:
35y - 67
Step-by-step explanation:
8(5y - 8) - (5y + 3)
Multiply the 8 with what is in the parentheses.
40y - 64 - 5y + 3
Subtract like terms.
35y - 67
The answer to this question is 3 19/20
