A pan is heated to 409°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 71°F. The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes. D = 338e^-0.03t What is the approximate temperature of the pan after it has been away from the heat for 8 minutes? A. 336.9°F B. 500.7°F C. 265.9°F D. 194.9°F
Answer: C. [tex]265.9^{\circ}F[/tex]
Step-by-step explanation:
Given: The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.
[tex]D = 338e^{-0.03t}[/tex]
At t= 8 minutes, we get
[tex]D = 338e^{-0.03(8)}\\\\\Rightarrow\ D = 338e^{-0.24}\\\\\Rightarrow\ D = 338(0.786627861067)\\\\\Rightarrow\ D = 265.88\approx265.9^{\circ}F[/tex]
The approximate temperature of the pan after it has been away from the heat for 8 minutes= [tex]265.9^{\circ}F[/tex]
it it a acute, obtuse, or Right someone plzzzz help me
Answer:
Acute angle
Step-by-step explanation:
Obtuse are a bit slanted Right angles are Shaped like an L
Answer:
Obtuse
Step-by-step explanation:
This is an obtuse triangle. Because the degrees of the angle is more than 90 degrees. A right triangle's degrees is 90 exactly and usually has a square marking the angle, an acute is less than 90 degrees for the angle.

Does a gas give off or absorb energy when it turns into a solid? Explain your answer.
You dont have to answer both just helping me with one would help me out!!! :)
also robot scammers stop giving me random links
Answer:
1. Consider a hot pot taken off the stove and placed on a tile countertop. At first it cools quickly. As it cools, the difference in temperature between the pot and the room air becomes less, and so it takes a long time for the pot to lose enough heat to match room temperature. Two objects at the same temperature are said to be in equilibrium.
2. When a liquid changes into a gas it absorbs energy. When it changes into a solid it gives off energy...If a solid (dry ice for example) is allowed to sublimate into a gas, it absorbs heat - that's why it feels cold when you touch ice. So, if a gas changes into a liquid, it give off heat as an opposite effect. Anytime you compress a gas, it gets warmer.

What is statistics?The practice or science of collecting and analysing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.
1st Period: Minimum = 60, Lower Quartile = 75, Median = 80, Upper Quartile = 90, Maximum = 98
* Range = 98-60 = 38; *Interquartile Range = 90-75 = 15
2nd Period: Minimum = 70, Lower Quartile = 80, Median = 85, Upper Quartile = 91, Maximum = 95
* Range = 95-70 = 25; *Interquartile Range = 91-70= 21
Hence the solutions are:-
B - lowest score was a 60 in first period
C - IQR in 2nd period is 21, which is higher than 15 in first period
F - Approximately 75% (Q1-Q3) of first period scores are higher than 75% (Q1-Q3) of second period.

On Monday, a local hamburger shop sold a combined total of 352 hamburgers and cheeseburgers. The number of cheeseburgers
sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?
To answer this question, you could use algebra.
If the number of cheeseburgers was three times the number of hamburgers, we could write this as.
Cheeseburgers= 3x and Hamburgers = x
We can then write an expression for the total number of burgers.
4x = 352
Divide both sides by four.
x = 88
Because hamburgers = x in relation to the cheeseburgers, that would mean the number of hamburgers sold on monday was 88.

Answer:
30 minutes
Step-by-step explanation:
The hare and tortoise meet in 30 minutes at 240 feet.
Answer:
30minutes
Step-by-step explanation:
Tortoise = Hare
2m + 180 = 8m
collect like terms
180 = 8m - 2m
180 = 6m
divide both sides by 6
m = 180/6
m = 30
It will take 30 minutes for the tortoise and hare to meet.

Step: Substitute−x+3foryiny=x−1:
y=x−1
−x+3=x−1

Find the value of x in 2x – 13 = 5
Answer:
x=9
Step-by-step explanation:
So first, you have to add 13 to both sides to isolate the x so that will make the equation 2x=5+13. Add 5 and 13 to get 18. The equation will now be 2x=18. Divide both sides by 2 because we want x to equal one. This will make it x=18/2. Simplify that and get x=9
Hope this helps
Question
Find the value of x in 2x – 13 = 5 .
ANSWER
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication, and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Hence, this information ( x = 9 )

Ken is going to throw a biased dice once.
The probability that the dice will land on six is 0.3
(b) What is the probability that the dice will not land on six?
Answer:
0.7
Step-by-step explanation:
Given a biased dice :
Probability of landing on 6 = P(6) ;
P(6) = 0.3
Recall :
P(A') = 1 - P(A)
Therefore,
If
P(6) = 0.3
P(not landing on 6) ; P(not 6) ;
P(not 6) = 1 - P(6)
P(not 6) = 1 - 0.3 = 0.7
Hence, Probability of not landing on 6 = 0.7
