The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):
If the volume of the cone is 270pi and the height of the cone is 10, then:
The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:
The total volume is 513 pi cm^3
Answer:
(1, 4)
Step-by-step explanation:
Below are a few points for Equations (1) and (2).}
Equation (1) is the blue line in the graph below.
Equation (2) is the red line.
The two lines cross at the black dot
Your four points are labelled . The one that is closest to the intersection is (1, 4).
The approximate solution to the system of equations is (1, 4).
Answer:
3
Step-by-step explanation:
Choose a variable to represent the number to be added to 5 and 3.
"Cross-multiply."
Check: The ratio of 5+3 to 3 + 3 is 8:6, equal to the ratio 4:3.
Answer:
The correct option is D.
Step-by-step explanation:
The given equation is
According to the addition property of equality 
and 
are equivalent equations.
Use addition property of equality, add 3x on both the sides.
Therefore Sam's work is incorrect because he make calculation mistake.
According to the subtraction property of equality and 
are equivalent equations.
Use subtraction property of equality, subtract 5x from both the sides.
Therefore Roy's work is correct because he used subtraction property.
Option D is correct.
