The true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.
<h3>How to explain the cost?</h3>
In this situation, the function is f (t), when t is a value between 0 and 30. The cost is $0 for the first 30 minutes
When t is a value between 30 and 90, the cost is US$ 5 if the connection takes between 30 and 90 minutes.
Here, the true statement about the Internet connection cost is D. Any amount of time over an hour and a half would cost $10.

Answer:
A.
positive and negative 5 and square root of 29
Answer: x = 4
y = - 3
Step-by-step explanation:
The given system of simultaneous equations is expressed as
x-3y = 13 ------------------------1
2x+4y=-4--------------------------2
We would apply the method of substitution in solving the equations. From equation 1, we would make x to stand alone by adding 3y to the left hand side and the right hand side of the equation. It becomes
x - 3y + 3y = 13 + 3y
x = 13 + 3y
Substituting x = 13 + 3y into equation 2, it becomes
2(13 + 3y) + 4y = - 4
26 + 6y + 4y = - 4
26 + 10y = - 4
Subtracting 26 from the left hand side and the right hand side of the equation, it becomes
26 - 26 + 10y = - 4 - 26
10y = - 30
Dividing the left hand side and the right hand side of the equation by 10, it becomes
10y/10 = - 30/10
y = - 3
Substituting y = - 3 into x = 13 + 3y, it becomes
x = 13 + 3 × - 3
x = 13 - 9
x = 4
Answer:
A
Step-by-step explanation:
Because it said 100 sea shells and 2 fewer and each bucket.
Bucket B contains 130 which is way more.
Bucket c contains only 80
Bucket D contains 110 so it has to be A.
Have a great day! :)
Answer:
The angle 2pi/3 terminate in quadrant II
Step-by-step explanation:
Quadrant I ⇒ 0 < θ < (π/2)
Quadrant II ⇒ (π/2) < θ < (π)
Quadrant III ⇒ (π) < θ < (3π/2)
Quadrant IV⇒ (3π/2) < θ < (2π)
When θ = 2π/3
∴ (π/2) < θ < (π)
So, The angle 2pi/3 terminate in quadrant II
