Answer:
67 pages in 1 hour
Step-by-step explanation:
A "unit rate" is a rate expressed with "one unit" in the denominator:
(201 pages)/(3 hours) = (201/3) pages/hour = (67 pages)/(1 hour)
Often, the unit of interest is a time unit. Here, it is 1 hour.
Answer: Aₙ = Aₙ₋₁*3; where A₀ = 2.5
Step-by-step explanation:
Let's try with some known sequences:
Arithmetic.
The difference between consecutive terms is constant:
7.5 - 2.5 = 5
22.5 - 7.5 = 15
We can already see that it is not an arithmetic sequence.
Geometric:
The ratio between consecutive terms is constant.
7.5/2.5 = 3
22.5/7.5 = 3
67.5/22.5 = 3
...
We can already see that this is a geometric sequence.
Then we can write the n-th term as:
Aₙ = Aₙ₋₁*3, where A₀ = 2.5
Its a. becuase there are an equal
Answer:83
Step-by-step explanation: A triangle is 180 degrees in total so if you take 90+45=135 then you subtract 52 from 135 and you get 83
so x=83
