Answer:
A
Step-by-step explanation:
-19-11 = -19 + (-11)
For this case we have to by definition:

Where:
d: It is the density
M: It's the mass
V: It is the volume
According to the data we have to:

On the other hand we have that 1 meter is equivalent to 100 centimeters. Thus the measurements of the walkway are:
600 cm long, 100 cm wide and 10 cm thick. Looking for the volume we have:

According to the formula we have:

Thus, the mass of the walkway is 1,800,000g
Answer:
1,800,000g
Answer:
answer is 0.4
Step-by-step explanation:
Answer:
If this is not the right answer I am very sorry.
cone: 192
cylinder: 86.7
in all: 278.7
Step-by-step explanation:
16x12=192 = cone
17x5.1=86.7 = cylinder
192+86.7=278.7 = in all
Answer:
the cost is 
Step-by-step explanation:
observing the graph
we know that
For the interval of x------>
-----> the cost is 
For the interval of x------>

For the interval of x------>
-----> the cost is 
For the interval of x------>
-----> the cost is 
In this problem we have
hours and
minutes
therefore
the value of x belong to the interval ![(3,4]](https://tex.z-dn.net/?f=%283%2C4%5D)
the cost is
