that's the solution ^
the answer is: 847.98 m^2
total book =1
1/5 + 2/3 + wed = 1
get a common denominator of 15
1/5 * 3/3 + 2/3 * 5/5 + wed = 1 * 15/15
3/15 + 10/15 + wed = 15/15
combine like terms
13/15 + wed = 15/15
subtract 13/15 on each side
wed = 15/15-13/15
wed = 2/15
He read 2/15 of the book on Wednesday
Answer:
1. c; 2. d
Step-by-step explanation:
1. 2*3 = 6
2. (1.43*1000)p + (2.2*1000) = (-4.001*1000)
Answer:
a) he rate of change of the volume of a snowball (due to melting) is proportional to the square of the volume at time t. Initially, the snowball has a volume of 900 cm3
and V(0) = 900
where A is a real constant, it appears because it says that the change i volume (dV/dt) is "proportional" to
. Furthermore, we should assume that A is a negative number, because the volume of the snowball will decrease as the time pasese by.
(b) For an insect moving along some path, the velocity at time t is proportional to the square root of its position.

Here again appears a constant B for the "proportional" part. And i wrote the velocity as
"the rate of change of the position with respect to te time".
