Answer: 800pi inches
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move
Answer:
72%
Step-by-step explanation:
Start by turning both percentages into decimals. To do this take the percent and divide it by 100. So, 60% = 60/100 or .6 and 80% = 80/100 or .8.
Next the student has already completed 20 quizzes. So, 50-20=30 remaining quizzes.
Quizzes already taken:
= 12 passed quizzes.
The remaining quizzes for the school year:
= 24 quizzes
So, Finally add them both together and divide by the total amount of quizzes:
12+24
= 36 passed quizzes
=.72
Now to convert it back into a fraction you multiply the decimal by 100.
= 72%
2ˣ = 2³
Since 2ˣ is EQUAL to 2³ and since 2 is equal to 2, then the solution is a must that the 2 exponents are equal.
Then x = 3
Answer:
This is not a quadratic equations
Answer:
56 in.
Step-by-step explanation:
Just add the 3 side lengths
= 7 + 24 + 25
= 56 in.
