Answer: M =
Step-by-step explanation:
M (x + y) + 4y = x + 2y (Multiply in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
1 and 5/10 or 1.15 has the same value of 15 tens
Answer:
Bobby answers 30% of all phone calls.
Step-by-step explanation:
To determine the proportion of calls that Bobby answers in the call center, knowing that Charlie handles one third as many calls as him, and that Alex handles six times as many calls as Charlie, the following equivalence must be made:
A = 6 C (1/3B x 6 = 2B)
B = B
C = 1/3 B
2B + B + 1/3 B = 100
3 1/3 B = 100
3.33 B = 100
B = 100 / 3.33
B = 30
Therefore, Bobby answers 30% of calls, Alex answers 60% and Charlie 10%.
By solving a quadratic equation, we will see that the ball hits the ground after 2.6 seconds.
<h3>How long does it take for the ball to hit the ground?</h3>
Here we need to solve the equation:
h(t) = 0 = -16t² + 40t + 4
This represents that the ball hits the ground.
So we just need to solve that quadratic equation, using the general formula we get:
We only care for the positive solution, which is:
t = (-40 - 43.1)/-32 = 2.6s
So the ball hits the ground after 2.6 seconds.
