Answer:
d = 2.75 or 11/4
Step-by-step explanation:
15 = 5 + 4(2d - 3)
15 = 5 + 8d - 12
15 = 8d - 7
<u>+7 + 7</u>
22 = 8d
22/8 = d
2.75 = d
Check:
15 = 5 + 4(2(2.75) - 3)
This is an Arithmetic Progression with 1st term 11 and common difference d=6
Number of Rows Number of seats Common difference " d"
----------------------- ----------------------- -------------------------------------
1st a₁ = 11
2nd a₁+d =17 d =2nd - 1st = 6
3rd a₁ +2d = 23 d =3rd - 2nd = 6
4th a₁ +3d = 29 d= 4th - 3rd = 6
-------------------------------------------------------------------------------
nth ROW a(n) = a₁ + (n-1)d
18th ROW a₁₈ = 11 + (18-1).6 = 11+(17)(6) = 113
General equation to predict the number of seat an the nth row:
Number of seats in nth row = a₁ + (n-1).d
Answer:
Sneakerheadz produced 900 pairs on Sunday. And on Monday, they produced shoes at a rate of 300 per hour.
Then the total number of pairs produced is:
S(t) = 900 + 300*t
where t represents the number of hours worked on Monday.
We know that Nuckicks only worked on Monday, and the same amount of time as Sneakerheadz, but at a rate of 480 sneakers per hour.
We can write the total number of pairs as:
N(t) = 480*t
Now we know that Nukcicks produced in Monday the sane number of pairs than Sneakerheadz produced in the two days, then we have that:
S(t) = N(t)
900 + 300*t = 480*t
900 = 480*t - 300*t = 180*t
900/180 = t
5 = t
So the factories operated 5 hours on Monday.
Answer:
1/5
Step-by-step explanation:
well if you have 5 apples and 5 peaches that mean the probability you'll pick to apples is 2/10 which reduces to 1/5
Answer:
Step-by-step explanation:
nonrenewable resources are natural resources that cannot be easily replaced.
fossil fuels are nonrenewable....and I believe nuclear energy is nonrenewable only because it is produced from a fixed supply of raw materials which cannot be renewed
