You haven't actually told us HOW MANY consecutive odd numbers.

If there are three (3) of them, then they are 21, 23, and 25,
and the third one is 25.

Oh !  I think there MUST be three of them.  That's the only way
they can all be whole numbers.

Natali5045456 [20]

Answer:

  multiply the number in each can by the number of cans and add the extras

Step-by-step explanation:

You can add them all up. This is the total of the number in each can and the extras:

  8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +7

Or you can take advantage of the invention of multiplication to simplify repeated addition. Multiply the number in each can by the number of cans, then add the extras.

  15×8 +7 = 127

a grandmother deposits $6000 in an account that pays 9% compounded monthly. What will be the value of the account at the​ child'
valkas [14]

now, we're assuming she made the deposit at the child's birth, namely when year was 0, at the child's twenty-first birthday that'll be 21 years later.

~~~~~~ \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 &\$6000\\ r=rate\to 9\%\to \frac{9}{100}\dotfill &0.09\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years\dotfill &21 \end{cases} \\\\\\ A=6000\left(1+\frac{0.09}{12}\right)^{12\cdot 21}\implies A=6000(1.0075)^{252}\implies A\approx 39437.11

Dave receives a salary of $200 a week plus a commission of 10% of his weekly sales. An equation y=mx+b represents Dave’s weekly
eduard
<span><u><em>Answer:</em></u>
Dave makes $350 

<u><em>Explanation:</em></u>
In order to find this answer, we must first establish the equation for his earnings.
<u>We use slope intercept form:</u>
 y = mx + b,
where m = slope and b = y-intercept.

Since the problem states that his commission percentage is the slope and his base salary is the y-intercept, we can use them in the equation <u>to get the following: </u>
y = 0.1x + 200.

Now knowing that the x is the amount he sells, we can use the $1500 as x to find his total pay for the week:.
y = 0.1(1500) + 200,
y = 150 + 200,
y = 350. </span>

How many ways can six friends be arranged around a circular dinner table?
Mice21 [21]
A question such as this one is a little tricky since the people seated are not in a straight line. 

For a circular table seating question, (n-1)! formula is used. Without restrictions 5! people can be seated. 

You might be wondering why it is not 6!, this is because the first person will the the 6 person so you are accounting for the same person twice. 

Hope I helped :)
