Answer:
It will take her 3 hours to read 120 pages.
Step-by-step explanation:
The number of pages read(y) after x hour can be modeled by a linear function in the following format:

In which a is the number of pages read per hour and b is the initial number of pages read.
A straight line goes through (0, 0)
This means that when 
So



(0.5, 20)
When 
So




The function in:

According to the graph, which statement must be true?
It will take her 2 hours to read 60 pages.

Less than 2 hours for 60 pages, so this is false.
It will take her 3 hours to read 120 pages.

This statement is true.
It will take her 4 hours to read 180 pages.

More than 4 hours to read 180 pages. So false.
It will take her 5 hours to read 210 pages.

More than 5 hours to read 210 pages. So false.
Answer:
This can be done in 3645 ways
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

In this problem, we have that:
1 Beethoven symphony, from a set of 9.
1 Mozart concerto, from a set of 27.
1 string quartets, from a set of 15.
So

This can be done in 3645 ways
Answer: The answer would be letter A
slope (m)=-9/2
intercept on x-axis=56/9
intercept on y-axis=28
Explanation:
18x+4y=112
(18x)/112+(4y)/112=1
(x/1)/(56/9)+y/28=1
intercept on x-axis=56/9
intercept on y-axis=28
now, 4y=-18x+112
y=-9/2x+28
so, slope (m)=-9/2
Step-by-step explanation:
Move all terms that don't contain y to the right side and solve.
y
= 28 − (9
x)
/(2)
Ok so
1 find volume of 1 cube
2. find total volume of rectangular prism
1/2 m cubes
volume=side^3
side=1/2m (I guess since that was what was given)
v=1/2^3=1/8
so
volume of 1 cube times number of cubes=total volume
1/8m^3 times number of cubes=5m^3
multiply both siides by 8/1 m^3 to clea fraction (since 8/1 times 1/8=8/8=1)
number of cubes=40
needs 40 cubes
