Hello,
Here is the answer :
2x^3 + 8x .
Answer: Third red dot after 30 on the number line represents the approximate volume of a cone.
Step-by-step explanation:
Since we have have given that
Radius of cone = 3 units
Height of cone = 4 units
So, Volume of cone is given by

Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.

Answer:
3x + 2y = 16
x = 2 , y = 5
Step-by-step explanation:
Given that George bought x quarts at $3.00 per quart & y quarts at $2.00 per quart and he bought 7 quarts for $16.00
Considering the total cost
3x + 2y = 16
For the cost of each
x + y = 7
solving the 2 equations simultaneously be substitution
x = 7 - y
3(7 - y) + 2y = 16
21 - 3y + 2y = 16
-3y + 2y = 16 - 21
-y = - 5
Divide both sides by -1
y = 5
x = 7 -y
x = 7 - 5
= 2
