Answer:
45.50° F
Step-by-step explanation:
As per Newton's law,

When T(t) is the final temperature
= Temperature of surrounding
= Initial temperature
t =duration of cooling
k = constant


Now take natural log on both the sides



4.6347 - 5.0434 = -5k

k = 0.0817

= 
= 155 (02935)
= 45.49 ≈ 45.50° F
The correct answer is the second answer choice.
Answer:I hope this helps c=60.26
Step-by-step explanation:
The area is 289
First get like things on the same side:
-5/6b - 1/2b= -2/3 - 3/4
Then find equivalent fractions to make the equation easier to solve.
-5/6b - 3/6b= -8/12 - 9/12
Then just add things together and solve.
-8/6b= -17/12
-8b= 6(-17/12)
-8b= -17/2
b= (-17/2)/-8
b= 17/16
You can then plug the answer back into the original question to make sure it is the correct answer.
The required simplified value of x and y is 32 and 84 respectively.
Given that,
To find the values of x and y. State which theorem(s) you used.
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Vertical opposite angles
3x = 5x - 64
2x = 64
x = 32
Now,
5x - 64 = 5*32 - 64
= 160 - 64
= 96°
Now complementary angle y
y = 180 - 96°
y = 84°
Thus, the required simplified value of x and y is 32 and 84 respectively.
