I believe she should pack three bundles. 6 hours equals 360 minutes. Dividing 360 by 45 gives us 8. Multiplying 345 by 8 results in 2760. Then, dividing 2760 by 3 yields 920, and 310 times 3 equals 930.:)
Answer:
She is mistaken
Step-by-step explanation:
Step 1: input
135 for x in both equations
Step 2: Solve those equations. This will yield y = 5375 for the first equation and y = 4720 for the second, indicating that she is incorrect
Answer:
90 degrees
Step-by-step explanation:
Complete question
On Mr. Hunt's desk, a cup of coffee is cooling down. Its cooling can be described by the equation T=70(0.80)^x+20, where x represents time in minutes and T denotes the temperature in degrees Celsius. WHAT IS THE STARTING temperature of the coffee
To find the starting temperature, we set x = 0
Plug x = 0 into the formula;
T=70(0.80)^x+20
T =70(0.80)^0+20
Recognizing that any number raised to the power of zero equals 1, we have;
T = 70(1)+20
T = 70+20
T = 90 degrees Celsius
Thus, the starting temperature of the coffee is 90 degrees
