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
Answer:
1. x=0
2. m=5
3. x=8
4. x=-8
5. x=49
6. x=-133
Step-by-step explanation:
1. 9x=0
2. -20=-4m, 20=4m
3. 2x=16
4. x/8=-1, x=-1x8
5. x/7=7
6. After simplifying: −1/19(x)=7
Hope this helped, I just simplified all the steps for the step by step explanation. Have a great day and stay safe, happy, and healthy!
Answer:
b = 6.928
Step-by-step explanation:
Looks like a job for the Pythagorean Theorem.
a^2 + b^2 = c^2
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b = 6.928
Hope it helps!!
The interval level of measurement is a number scale that classifies both order and the value change between each number. For example, a ruler has intervals 1, 2, and 3 inches. The distance between 1 to 2 inches is the same as the distance between 3 to 4 inches.
1) x= 2
6x2+10=22
2) x = 2
6x2-4=4x2
