There are 217 chairs cleared and 36 chairs left
ANSWER:
equation:
217 + 36 = 253
Answer:
Step-by-step explanation:
On Monday, Nora read ¼ of the book, therefore she is left with ¾ of the original book.
Then on Tuesday, she read 2/5 of what was left on Monday therefore she is left with 3/5 of ¾ of the original book. This is equal to:
(3/5) (3/4) = 9/20
She still needs to read 9/20 of the book or 0.45 or 45% of the book.

13x^2-15x+12
Step-by-step explanation:
Answer:
P = 500 - 40t
Step-by-step explanation:
P is the number of pages has left to read
the initial value is 500
the rate of change is 40 pages per hour (t)
you must subtract from the initial
The equation is P = initial - 40t or
P = 500 - 40t
To check, at 0 hours you have 500 pages or P = 500 - 40(0)
at 10 hours, P = 500 - 40(10) = 500 - 400 = 100
Answer:
67 cubic inches
Step-by-step explanation:
Given height of cone = 4 inches
Given height of cone is half of diameter of base of cone
If D is diameter, then
4 inches = 1/2 D
=> D = 8 inches
Radius for any circle is half of diameter of circle.
Thus for given cone
radius = 1/2 D = 1/2 * 8 = inches.
Area of circle is given by where r is radius of circle.
Thus area of given base of cone is given as below
We know that volume of cone is given by
volume = 1/3(area of base * height)
Thus,
volume of given cone = 1/3(50.24)*4 =66.98 cubic inches
volume of cone in nearest cubic inches is 67 .
