1.2a+1.15b=(680+118)=798   and a+b=680, 

Solving for a from the second equation we get: a=680-b

Using 680-b for a in the first equation we get:

1.2(680-b)+1.15b=798

816-1.2b+1.15b=798

816-0.05b=798

-0.05b=-18

b=360, and since a=680-b

a=320

So the a team was supposed to produce 320 parts and the b team was supposed to produce 360 parts...

check...

320*1.2+360*1.15=680+118

384+414=798

798=798

1.2a+1.15b=(680+118)=798
a+680-b
1.2(680-b)+1.15b=798
816-1.2b+1.15b=798
816-0.05b=798
-0.05b=-18
b=360, a=680-b
a=320
team A=320 parts
team B=360 parts

Find the 9th term of the geometric sequence whose common ratio is 1/3 and whose first term is 2.
raketka [301]

Answer:

2/6561

Step-by-step explanation:

Geometric sequence formula : a_n=a_1(r)^n^-^1

where an = nth term, a1 = first term , r = common ratio and n = term position

given ratio : 1/3 , first term : 2 , given this we want to find the 9th term

to do so we simply plug in what we are given into the formula

recall formula : a_n=a_1(r)^n^-^1

define variables : a1 = 2 , r = 1/3 , n = 9

plug in values

a9 = 2(1/3)^(9-1)

subtract exponents

a9 = 2(1/3)^8

evaluate exponent

a9 = 2 (1/6561)

multiply 2 and 1/6561

a9 = 2/6561

Tom opens a bank account and makes an initial deposit of 500$. Then banker tells Tom that he is going to receive an annual rate
Arturiano [62]

~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$500\\ r=rate\to 6\%\to \frac{6}{100}\dotfill &0.06\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &15 \end{cases} \\\\\\ A=500\left(1+\frac{0.06}{1}\right)^{1\cdot 15}\implies A=500(1.06)^{15}\implies A\approx 1198.28

How many different three-letter initials with none of the letters repeated can people have?
viva [34]
This is a probablity question

there are 3 slots, 26 letters of the alphabet

so in the first slot, we have 26 possible letters
2nd slot, we have 25 possible letters (we used one for the first slot)
3rd slot, we have 24 possible letters, (we used 2 for first and 2nd slot)

so in total, we have 26*25*24 or 15600 different 3 letter initials with no repeated letters
