What is the volume of this entire prism

Mathematics
1 answer:
lisabon 2012 [21]3 years ago
8 0

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

2. Which of the following systems of inequalities represents the graph?
Rom4ik [11]

Answer:

Option: D is the correct answer.

D)  –2x + y ≥ 4

         x + y < 2

Step-by-step explanation:

We are asked to find the linear inequality that represents the following graph.

Clearly from the graph we could observe that one line is dotted and the other is solid line.

i.e. one inequality is strict while the other is a inequality with equality sign.

<u>Dashed line:</u>

It passes through (0,2) and  (2,0).

Hence, the equation of line is:

y-2=\dfrac{0-2}{2-0}\times (x-0)\\\\\y-2=\dfrac{-2}{2}\times x\\\\y-2=-x\\\\x+y=2

As the shaded region is towards the origin.

Hence, the inequality will be:

x+y<2.

<u>Solid line:</u>

The line passes through (-2,0) and (0,4).

hence equation of line is:

y-0=\dfrac{4-0}{0-(-2)}\times (x+2)\\\\

i.e

y=\dfrac{4}{2}\times (x+2)\\\\y=2\times (x+2)\\\\y=2x+4\\\\-2x+y=4

Now, as the shaded region is away from the origin hence the inequality which will be used is:

-2x+y\geq 4

Hence, option: D is the correct answer.

D.   –2x + y ≥ 4

       x + y < 2

Vanyuwa [196]

Answer:

7040

Step-by-step explanation:

C= 2000

B = 20/100 x 2000 = 400 + 2000 = 2400

A= 10/100 x 2400 = 240+2400= 2640

2000 + 2400 + 2640 = 7040

Can someone please help me with math
DaniilM [7]

Answer:

B

Step-by-step explanation:

they want us to find the equation in slope intercept form

which is y= mx + b

where m = slope and b = y intercept

the slope is change in y over change in x

as y goes up 1 x goes up 1 so the slope is 1 or m=1

the y intercept is at point (0,1)

so the y intercept is 1

now we add it all together and get that the equation Is

y=x+1
