Answer:
100x=256.25
Step-by-step explanation:
x/1025=25/100
What is 25% of 1025
that would be 1025×25
100x=256.25

Answer:
43.75 liters.
Step-by-step explanation:
125% = 1.25 as a decimal fraction.
number of liters of milk = 35 * 1.25
= 43.75 liters.
Answer:
69.92°F
Step-by-step explanation:
Given:
Initial temperature ( i.e at time, t = 0) = 40°F
Temperature of the room = 70°F
Temperature after 10 minutes ( i.e at time t = 10 ) = 48°F
Now, from Newton's law of cooling
T'(t) = k(A - T(t))
T(t) temperature after time t
T'(t) =
here, A is the room temperature
thus,
= k(70 - T)
or
= kdt
on solving the differential equation, we get
T =
............(1)
Now from the boundary conditions,
i.e at time, t = 0; T = 40°F
we get,
40 = 
or
C = 30
and,
at time, t = 10; T = 48°F
thus,
48 = 
or
k =
or
k = 0.03
Therefore,
for t = 25
from 1 we have
T = 
or
T = 70 - 0.0780
or
T = 69.92°F
The first roller coaster is 35 for 5 which means $7 for 1 ride
the second roller coaster is 59 for 11 which means 59 divided by 11 get 5.36
5.36 times 11 = 58.96 probrably a combo so it is estimated upward
