Answer: 1 hour 20 minutes
Step-by-step explanation:
Given : The old machine could shred a truckload of paper in 4 hours.
Rate of work done by old machine =
The new machine could shred the same truckload in 2 hours.
Rate of work done by new machine =
Let 't' be the time taken by both of them working together , then we have the following equation:-
Since 1 hour = 60 minutes
Then,
Hence, it will take 1 hour 20 minutes to shred the same truckload of paper if Ron runs both shredders at the same time.
Answer:
The correct answer is 4294967296 possible ways to complete such a test.
Step-by-step explanation:
Step 1
The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are ways to complete the first step, ways to complete the second step, , and ways to complete the step, this process can be carried out in ways.
Step 2
We use the fundamental principle of counting with for a total of steps. This test can be carried out in ways. This comes from multiplying 4 by itself 16 times.
A(1,-3)
Solution because that the coordinate they meet at and you read it from the x axis to the y axis
Answer:
Step-by-step explanation:
Rewrite this equation in standard quadratic form: x^2 + 13x + 4 = 0.
Here the coefficients are 1, 13 and 4, so the discriminant is
b^2-4ac, or 169 - 4(1)(4) = 153
Since the discriminant is + there are two real, unequal roots. They are:
-13 ± √153
x = ------------------
2
x = ----------------
