Answer:
9.8 percent decrease
Step-by-step explanation:
To find the percent decrease, we take the original value and subtract the new value and divide by the original value.
percent decrease = (original - new)/ original
= (23.5 - 21.2)/ 23.5
=2.3/23.5
=.09787234
This is in decimal form. Multiply by 100 to put it in percent form
9.787234 percent
Round to the nearest tenth so we look at the 8 and round up.
9.8 percent decrease
Answer:
c.t^16
Step-by-step explanation:
(t^8)^2
= t^(8 *2)
= t^16
Answer: You need to wait at least 6.4 hours to eat the ribs.
t ≥ 6.4 hours.
Step-by-step explanation:
The initial temperature is 40°F, and it increases by 25% each hour.
This means that during hour 0 the temperature is 40° F
after the first hour, at h = 1h we have an increase of 25%, this means that the new temperature is:
T = 40° F + 0.25*40° F = 1.25*40° F
after another hour we have another increase of 25%, the temperature now is:
T = (1.25*40° F) + 0.25*(1.25*40° F) = (40° F)*(1.25)^2
Now, we can model the temperature at the hour h as:
T(h) = (40°f)*1.25^h
now we want to find the number of hours needed to get the temperature equal to 165°F. which is the minimum temperature that the ribs need to reach in order to be safe to eaten.
So we have:
(40°f)*1.25^h = 165° F
1.25^h = 165/40 = 4.125
h = ln(4.125)/ln(1.25) = 6.4 hours.
then the inequality is:
t ≥ 6.4 hours.
