Answer:
1072.3
Step-by-step explanation:
A hemisphere is half of a sphere, so the volume V of the hemisphere is the volume of the sphere divided by 2.
V = (2/3)*

= (2/3)*

= (2/3)*
*512
= 1072.3
Answer:
y = 5x + 4
Step-by-step explanation:
Equation of a line passing through a point (x', y') and having slope 'm' is represented by,
y - y' = m(x - x')
If the point through which the given line is passing is (0, 4) and slope of the line is '5'
Equation of the line will be
y - 4 = 5(x - 0)
y = 5x + 4
Therefore, equation of given line is y = 5x + 4

Answer:

Step-by-step explanation:
Let k represent the price in dollars at which Nita will buy the keyboard.
We have been given Nita wants to buy a new keyboard for her computer. She will buy the keyboard when it is on sale for under $50.
This means that Nita will buy the computer, when its price (k) is less than $50. We know that sign < represents less than.
We can represent our given information in an inequality as:

Therefore, our required inequality would be
.
