Answer:
r≈7ft
Step-by-step explanation:
C=2πr (π is pi)
r=C
2π=43.96
2·π≈6.99645ft
Answer:

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
Step-by-step explanation:
For this case we can calculate the % of change with the formula of relative change given by:

For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base
And the New value would be 120 who represent the height of the oak tree
If we replace into the formula we got:

And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:
a(n)=15+1(n-1)
All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:
s(n)=(2an+dn^2-dn)/2 (that is just the result of ((a+a+d(n-1))(n/2)) )
Since a=15 and d=1 this becomes:
s(n)=(30n+n^2-n)/2
s(n)=(n^2+29n)/2 so
s(10)=(100+290)/2
s(10)=195 logs
Answer: it’s easy your teacher should’ve taught this in 9th
Step-by-step explanation:
48=4% loaded on truck and they have 96% left to load
So set up a proportion and it should look like this
48 over x = 4 over 100
48/x=4/100
Do cross multiplication 100×48= 4,800÷ 4 = 1,200 total on truck
