The 27th term of the Arithmetic sequence defined by an = -7.1 -2.1n is -63.6. This is determined by substituting n=27 into the formula.
The problem here is asking us to find the 27th term, denoted as a27, of an arithmetic sequence. The general formula for the nth term of such a sequence is an = a1 + (n-1) * d, where a1 is the first term and d is the common difference.
However, in this case, the formula given is an = −7.1 − 2.1n. Therefore, we just need to substitute n = 27 into the formula to find a27.
Following that, we have a27 = -7.1 -2.1*27. Doing the calculation, we get a27 = -63.6. Therefore, the 27th term of the sequence is -63.6.

Answer:
An = -63.8
Step-by-step explanation:
−7.1 − 2.1n
−7.1 − 2.1(27)
-7.1 - 56.7 = -63.8
An = -63.8
shirts: 5 10 15
profit: $7.50 $15.00 22.50
Answer:
$1.50
Step-by-step explanation:
To find the unit rate, we can divide the number of shirts to the profit that was made to find the unit cost per shirt.
7.50 / 5 = $1.50
15 / 10 = $1.50
22.50 / 15 = $1.50
Best of Luck!
Answer: 1.5
Step-by-step explanation:
7.50/5 = 1.5
15/10 = 1.5
22.50/15 = 1.5
volume_____cubic inches
Answer:
Surface area is =548
Volume = 840 in³
Step-by-step explanation:
l × w, l × w, w × h, w × h, l × h, l × h
70 + 70 + 84 + 84 + 120 + 120 = 548
l × w × h = 840
Answer:
In any quantitative science, the terms relative change and relative difference are used to compare two quantities while taking into account the "sizes" of the things being compared. The comparison is expressed as a ratio and is a unitless number.

11 - 3x = 44
Answer:
Subtract 11 from both sides
Step-by-step explanation:
X has to be alone
Answer:
Subtract 11 from sides
Step-by-step explanation:
You have to get the x by itself first
The maturity value in John's account is $8347.5.
Given that, principal =$6300, rate of interest =6.5% and the time period =5 years.
Maturity value is the amount due and payable to the holder of a financial obligation as of the maturity date of the obligation. The term usually refers to the remaining principal balance on a loan or bond. In the case of a security, maturity value is the same as par value.
Now, S.I. = (P×T×R)/100
= (6300×5×6.5)/100
= 2047.5
So, interest =$2047.5
Maturity value = Principal + Interest
= 6300+2047.5
= $8347.5
Therefore, the maturity value in John's account is $8347.5.
