Answer:
According to the passage, we have the next equation:
where "K" is a proportional constant
Leaving at the end with the next equation:
Integrating the equation, we have:
where "C" is a constant
Then, we have the 2 conditions for the problem:
1) t=0 → r=10
Replacing in the equation, we have C = 10
2) t=5 → r=8
Replacing in the equation, we have K = -0.4
Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation
t = 25 minutes
The answer is 6.5
Explanation : 1. Find out the increase number by subtracting 4.58 - 4.30 = 0.28 or 6.51%
2. Divide the increase number 0.28 by 4.30 and multiple by 100 which gives you 6.51162791 .
3. Get rid of all the numbers behind 5 and you can’t round it because 1 is too small. Which then gives you the answer 6.5 :) <3
Answer:
m<U=70
Step-by-step explanation:
we know that the measure of the out side angle is equal to the measure of the 2 inside angles, so 120-50=70
This is false because when you multiply a number by 10, you simply move the decimal place one to the right. In this case, when we multiply 0.02 by 10, we get .2. Had we multiplied 0.02 by 100, we would have gotten 2.
To solve for revolutions, we will have to take the distance of the travel and divide that by the circumference of the wheel.
Distance of travel = 3.67 miles
Circumference of wheel = 82.6 inches
We have to convert the inches to miles. There are 63360 inches in one mile.
Circumference of wheel = 82.6 in * (1 mi/63360 in) = 0.0013 miles
Revolutions = Distance/Circumference = 63,538.46 revolutions
