Answer: the height in inches, of the pile after 3 weeks is 34 11/12 inches
Step-by-step explanation:
Each consecutive week for the next 5 weeks the height of pile increase by 8 7/12 inches. Converting 8 7/12 inches to improper fraction, it becomes 103/12 inches. The height is increasing in an arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 17 3/4= 71/4 inches
d = 103/12 inches
n = 3 weeks
the height in inches, of the pile after 3 weeks, T3. Therefore,
T3 = 71/4 + (3 - 1)103/12
T3 = 71/4 + 2 × 103/12 = 71/4 + 103/6
T3 = 419/12 inches = 34 11/12 inches
Answer:
You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since they already have a common denominator of x+1 we can add the numerators
(2x+4-x+5)/(x+1)
(x+9)/(x+1)
The area is 7 units squared.
3-1 = 2
5--2 = 7
2x7 = 14
14/2 = 7
Answer:
the answer is 60 inches
Step-by-step explanation:
you have to subtract the perimeter and the numbers that are shown after you add them
238-118= 120 then you have to divide that in half wich =60.
so (A)= to 60 inches.
