Is skipped a number and that's not good
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
Answer:
Yes
Step-by-step explanation:
That number is irrational because it does not repeat and rational number repeats
Volume of Solids
The volume of the solid is 758.83 in³
Step-by-step explanation:
Given that the cone and half sphere is hollow
The volume of the cone =
The Volume of the sphere = 
So the Volume of the half sphere =
The volume of solid = volume of cone + volume of the half sphere

Given
height h = 19 in
radius r = 5 in
= 
= 1/3 × 3.14 × 5 × 5 × 19
= 497.16 in³

= 2/3 × 3.14 × 5 × 5 × 5
= 261.67 in³
V = 497.16 in³ + 261.67 in³
= 758.83 in³
Hence the volume of the solid is 758.83 in³
The given system of equations represent a single line with positive slope. So option C is correct.
<u>SOLUTION:
</u>
Given system of equations are

Now, if we observe,
multiplying the
equation with 2 results in
equation.
which means the two line equations represents the same line.
Now, let us find the slope of line, 
So, the line has a positive slope.
