Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5
so $409.5 is your answer
Answer:
113.1 cubic inches
Step-by-step explanation:
The volume of a cylinder is given by the formula:

Where
V is the volume
r is the radius
h is the height
Given, h = 9 and r = 2, we substitute and find the volume:

We need answer to nearest tenth, that is 1 decimal place, so we round of the answer as:
113.1 cubic inches
Answer:
The answer is C. 49x2 + 42x + 9
Step-by-step explanation:
Use the sum-product pattern
49
Answer:
x<2
Step-by-step explanation:
-1 + 6 (-1 - 3x) > -39 - 2x
-1 - 6 - 18x > -39 - 2x <--- multiply the 6 by 3
-7 - 18x > -39 - 2x
-7 - 18x + 2x > -39 <--- add 2x to the other side
-7 - 16x > -39
-16x > -39 + 7 <--- add 7 to the other side
-16x > -32
x < -32/-16
x < 2
Volume of Sphere
The volume of sphere is 904.32 cm³
Step-by-step explanation:
Sphere is a geometrical object in three dimensional space (like the surface of a ball). Every point on its surface of a sphere equidistant from its center.
Circle is a two dimensional figure where as sphere is a three dimensional figure.
The volume of the sphere is defined as 
where r is radius of the sphere
V = 
Given radius r = 6 cm

V = (4/3) × 3.14 × 6³
= (4/3) × 3.14 × 216
= 904.32 cm³
Hence the Volume of the sphere is 904.32 cm³
