If a pizza is divided into eights, that means that there are eight pieces of pizza. There are three people so if three people each eat one slice, that means there are five pieces of pizza left which is 5/8. 4/8 equals one half. So one more slice of pizza must be eaten for half of the pizza to remain.
Answer:
A should be the correct answer
Step-by-step explanation:
1/3π xr^2xh just means "3.14 x r^2 x height ÷ 3"
Answer:
y = 1/4x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.
Plug this value (1/4) into your standard point-slope equation of y = mx + b.
y = 1/4x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.
-1 = 1/4(4) + b
To find b, multiply the slope and the input of x (4)
-1 = 1 + b
Now, subtract 1 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 1/4x - 2
This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)
Hope this helps!
