I think it should be an= 49x3^(n-1)
So if you're driving 25 miles per hour, it would take you 7 hours to drive 175 miles.
175 miles ÷ 25 miles = 7 hours.
Answer:
58 degrees
Step-by-step explanation:
subtract 122 from 180
Answer:
10.59%
Step-by-step explanation:
percentage of change is given by
{(old number - new number)/old number} * 100

given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.
With the given hint to be able to answer the question above, the equation for Newton's law of cooling is as follows:
T(t) = T(s) + (T0 - Ts)e^-kt
where T(t) is the body's temperature at any given time, Ts is the temperature of the surrounding, T0 is the initial temperature, and k is constant.
Substituting the values with the given above,
T(t) = 76 + (170 - 76)*e^(-0.34)(7)
This gives us the answer,
T(t) = 84.7 degrees F
