Answer:
B. $42.60.
Step-by-step explanation:
On the first day price is 43.85 + 2.70 = $46.55
second day price is 46.55 + 2.70 = $49.25
For the next 2 days it goes down $1.10 so the price is $49.25 - 2.20=$47.05
On the last day it loses $4.45 so the final price is $47.05-4.45 = $42.60.
Sandi did not follow PEMDAS. She added before multiplying and dividing. Her answer should be 18 because 6 • 4 = 24, 2 / 2 = 1, 24 + 1 = 25, 25 - 7 = 18
Step-by-step explanation:
Rate of drop of temperature = Change in temperature/Rate
=> (165 - 135)/15
=> 30/15
=> 2 ⁰F/min
Now, The time at which the temperature of will be 70⁰F = 70/Rate
=> 70/2
=> 35 min
Time for 110⁰ F
=> 110/2
=> 55 min
Step-by-step explanation:
3^(-3) * 10^(-2)
= 1/27 * 1/100
= 1/2700.
