Answer:
86ft²
Step-by-step explanation:
3x2/2=3
3x2/6=3
10x2.5=25
10x2.5=25
3x10=30
30+25+25+3+3=86
Step-by-step explanation:
Well talking about the practical use of Arthematic sequence or series..
i have an example..
suppose there is a highway and in most condition.. Petrol or diesel station are kept in a common distance..
now you can easily calculate or predict where the next petrol or diesel station is ..
and about Geometric sequence or series
There are many uses of geometric sequences in everyday life, but one of the most common is in calculating interest earned. Mathematicians calculate a term in the series by multiplying the initial value in the sequence by the rate raised to the power of one less than the term number. The sequence allows a borrower to know the amount his bank expects him to pay back using simple interest
and
Physicists use geometric progressions to calculate the amount of radioactive material left after any given number of half-lives of the material. During each half-life, the material decays by 50 percent.
Answer:
Y=2400*3.6^t
Step-by-step explanation:
y=a*b^x
a is the initial amount
b is the decrease/increase rate
x is the amount of time
Hope it helps!
Answer: the equation is 4t = 3.60
The cost of 1 pound of banana is $0.9
Step-by-step explanation:
Let t represent the cost of 1 pound of banana in dollars.
Gavin paid for 4 pounds of bananas. This means that the total cost of 4 pounds of banana will be 4× t = $4t
He gave a $10 bill to the seller and he was given back $6.40. This means that the actual cost of 4 pounds of banana would be
10 - 6.40 = $3.60
Therefore,
4t = 3.60
t = 3.60/4 = $0.9
