Answer:
The diameter is equal to the circumference divided by the number pi
Step-by-step explanation:
we know that
The circumference of the circular walkway is equal to
where
D is the diameter
we have
substitute
so
Divide the diameter by the circumference
The diameter is equal to the circumference divided by the number pi
Answer:
NO
Step-by-step explanation:
Let h(t) represent the distance the pack is located above the ground at time t. Then h(t) = 20 ft - 16t^2 ft. Notice how h = 20 ft (the initial height) and that it decreases as t increases.
How long does it take for the pack tohit the ground? Set h(t) = 0 and solve for t:
0 ft = 20 ft - 16t^2 ft yields 16t^2 ft = 20, or t^2 ft = 20/16, which is greater than 1. So the question "Will the backpack hit the ground in 1 second" is answered by NO.
The median is 6. What you do is list all the numbers in order and cross one on each side out until your left with one.
Answer:
A. 7 over 36
Step-by-step explanation:
One ninth =1/9
One twelfth = 1/12
1/9+ 1/12= 12+9/108
= 21/108
We can then reduce the fraction to the lowest denominator by dividing the numerator and denominator by 3
That will result in 7/36
