You just need to divide 13 and 2 and get 6.5.
Answer:
2009cm^2
Step-by-step explanation:
Given data
let the length be L
and the width be w
so
w= x
L=x+8
P= 180cm
P= 2L+2W
180= 2(x+8)+2(x)
180= 2x+16+2x
collect like terms
180= 4x+16
180-16= 4x
164= 4x
x= 164/4
x=41
W= 41cm
L= 41+8
L= 49cm
A= L*W
A=49*41
A=2009cm^2
Hence the area is 2009cm^2
Answer:
YES YES HE VENTED ITS NOT ME DONT WORRY
Answer:
Let's say that the whole book have 5a pages.
First day: a + 12
Second day: (4a)1/4+15= a + 15
Third day: (1/3)[ 4a - (a+15)] +18= a + 13
Forth day: 70
So we get this:
(a + 12) + (a + 15) + (a + 13) + 70 = 5a
a + 12 + a + 15 + a + 13 + 70 = 5a
3a + 110 = 5a
3a - 5a = -110
-2a = -110
a = 55
5a = 5(55) = 275
So the total pages are in the book is:
275 pages
To make it easier convert the times all into minutes.
2 hours 20 minutes = 120 minutes + 20 minute = 140 minutes
4 hours 10 minutes = 240 minutes + 10 minutes = 250 minutes
Then subtract:
250 minutes - 140 minutes = 110 minutes
Convert back to hours/minutes:
110 minute = 1 hour and 50 minutes
