Answer: See explanation
Step-by-step explanation:
A pizza is in the shape of a circle.
Since the perimeter is 10 inches, we have to find the radius. This will be:
2πr = 10
πr = 10/2
πr = 5
3.14r = 5
r = 5/3.14
r = 1.5924
Area = πr²
= 3.14 × 1.5924²
= 7.96 inches
= 8 inches approximately
Answer:
x=2, y=0. (2, 0).
Step-by-step explanation:
x-y=2
2.5x+y=5
---------------
x=y+2
2.5(y+2)+y=5
2.5y+5+y=5
3.5y=5-5
3.5y=0
y=0/3.5
y=0
x=0+2=2

The equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)
Step-by-step explanation:
Tom has read the first 40 pages of a book.
He plans to read another 12 pages each day
Since the total number of pages is p
And the Number of days required to read the book is d
if Tom read 12 pages per day, then in d days he would read 12 × d pages
h/e has already read 40 pages of the book
Then total pages of the book
p = 40 + (12 × d)
Hence, The equation that represents the relationship between , and the number of days he has been reading , d is p = 40 + (12 × d)
