The base of the prism in the diagram is rectangular, but the edges that are not parallel to the base are tilted. What is the vol
Aneli [31]

Answer:

Volume of the prism is 648cm^3

Step-by-step explanation:

Given:

Base of the prism is rectangular in shape

Height of the prism = 6 cm

Base length of the prism= 12 cm

Base width of the prism= 9 cm

To Find:

Volume of the prism=?

Solution:

Volume of the prism ,

V= Base area of the prism x  Height of the prism

Here in the figure  base of the prism is in  Rectangular form

So the base area of the prism = area of the rectangle

We know that the area of the rectangle is = length x height

Substituting the values

Area of the Rectangle = 12 x 9

Area of the Rectangle = 108

So  the are of the base of the prism is  108cm^2

Now

Volume of the prism,

V= 108 X 6

V= 648cm^3

Huey works 175 hours each month and earns $14.25 per hour after taxes. His monthly budget is shown. How much money is left over
steposvetlana [31]
For this case we have the following equation:
 y = 14.25x
 Where,
 x: number of hours
 y: total salary
 For x = 175 we have:
 y = 14.25 * (175)
 y = 2493.75
 The amount of money for unexpected expenses is:
 unplanned expenses = 2493.75 - 1250 - 200 - 350 - 400 - 225 - 300
 unplanned expenses = -231.25 <0
 We note that there is no money left for unexpected expenses
 Answer:
 
there is nothing left over

4.67,4.98,4.34 minutes what is the standard deviation for these three songs
ValentinkaMS [17]
First compute the mean:

(4.67 + 4.98 + 4.34) / 3 = 4.66

then compute the variance:

(4.67-4.66)^2 = 0.0001
(4.98-4.66)^2 = 0.1024
(4.34-4.66)^2 = 0.1024

sum of the three = 0.2049

then take the square root:

= 0.452

the standard deviation is 0.452
