Answer:

Step-by-step explanation:

Use LCM of 6 and 7 to find a number that is the same:

6 12 18 24 30 36 42

7 14 21 28 35 42

Since 42 shows up in both, the 42th voter gets a button and sticker.

Hope this helped.

Answer:

Step-by-step explanation:

We can break down what each term represents in the equation

60 is the constant. This is the base price that is paid regardless of workers and hours needed

Then there is 12nh. 12 represents the cost per hour for one worker. If the job takes only one hour, then it is 12 dollars per worker. Similarly, if the job only takes one person, then it is 12 dollars for each hour.

The most accurate answer is A

You begin the week with 20 units of milk. You purchase 40 units. Your ending inventory for the week is 30 units. How many units

Musya8 [376]

Answer:

30 units.

Step-by-step explanation:

Let x be number of milk units sold.

It has been given that You begin the week with 20 units of milk. You purchase 40 units. Therefore, total units of milk will be $20+40=60$ units.

It has been given that your ending inventory for the week is 30 units, which means after selling x units from 60 units you are left with 30 units.

We can set this information in an equation as:

$60-x=30$

$-x=30-60$

$-x=-30$

$x=30$

Therefore, you have sold 30 units.

1,030 at 4% compounded semiannually for 2 years

kotegsom [21]

Answer: $1114.91

Step-by-step explanation:

The formula for compound interest is

$A= P(1+\frac{r}{n})^{nt} \\$

Where

A = final amount

P = initial principal balance (1030 for this)

r = interest rate (0.04 for this)

n = number of times interest applied per time period (2 for this)

t = number of time periods elapsed (2 for this)

$A= 1030(1+\frac{.04}{2})^{(2)(2)} \\\\A= 1030(1+0.02)^{4} \\A=1030(1.02)^4\\A=1114.905125$

This rounds up to $1114.91
