As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one  
so volume = length * width * height
 volume of larger prism
 vp=45/4 ft^3 =11.25
 volume of small cubes
 vs=1/2*1/2*1/2
 vs=0.125 ft^3
 now numbers of cube that can fit
 n=vp/vs
 n= 11.25/.125
 n=90
 so 90 smaller cubes will completely fill in the prism

Which of the following has a positive value? sec (2pi/3) tan (2pi/3) cos (2pi/3) csc (2pi/3)
Darya [45]

Answer:  D) csc (2π/3)

<u>Step-by-step explanation:</u>

2π/3 is in Quadrant II

Quadrant II has a negative x-value and a positive y-value.

x-values are: cos & sec

y-values are: sin & csc

tan = y/x so will be negative in Quadrant II

A) sec = -

B) tan = -

C) cos = -

D) csc = +     this works!

Solve y = x + 8 for x.<br> x= y + 8<br> x=y - 8<br> x= -y + 8<br> x = -y - 8
Anna007 [38]
X = y - 8

Step by step
Y = x + 8
x + 8 = y
-8 -8
x = y - 8

What is the difference between an irrational number and an integer? (PLZ HELP ME ANSWER ASAP!!!! All help is appreciated! :D)
enot [183]
So, first off it would help if you could define the terms irrational number and integer. Well, an irrational number is basically any real number that can't be expressed as a ratio of integers. They also cannot be represented by terminating or continuing decimals. And an integer is pretty much any number that cannot be written as a fraction or decimal, such as -2, 13, 257. It is not 2 and 1/2, or 4.75. Those would not be integers. Do you think you can figure out the difference?
