Answer: choice C) 19/60

----------------------------------------------------------------------------------------------------

Explanation: 

Add up the minute values: 19+4+37 = 60

We have a total of 60 minutes. Of that total, 19 minutes is dedicated to news.

Divide the two values (19 and 60) to get the fraction 19/60. We can't reduce from here so we leave it like that.

torisob [31]

Step-by-step explanation:

 The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.

the expression for the volume of a cylinder is

volume-of-cylinder= \pi r^2h

the volume of a cone is a part of the volume of a cylinder

volume-of-cone= \frac{1}{3} \pi r^2h

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3

Which function has a range of all real numbers greater than or equal to -4​
shtirl [24]

Answer:

The domain is all real numbers, and the range is all real numbers f(x) such that f(x) ≤ 4. You can check that the vertex is indeed at (1, 4). Since a quadratic function has two mirror image halves, the line of reflection has to be in the middle of two points with the same y value.

Two mechanics worked on a car. The first mechanic worked for
Temka [501]
Write a system of equations:

x + y = 125

20x + 15y = 2100

Solving:

x = 125 - y

20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80

x + 80 = 125
x = 125 - 80
x = 45

The first charges 45$ per hour and the second charges 80$ per hour
