Natalka [10]

Answer:

1. 21,554 PER YEAR

2. 1658 PER MONTH

Step-by-step explanation:

so there are approximately 52 weeks per year

and alejandro juarez gets 829$ per 2 weeks

SO 829/2=414.5

so he gets 414.5 $ PER WEEK

2............LETS MULTIPLY THE AMOUNT OF MONEY PER WEEK BY THE WEEKS

SO 414.5*52=21554

SO ALEJANDRO JUAREZ EARNS 21,554$ PER YEAR

SO WE ALREDY KNOWS ALEJANDRO EARNS 414.5$ PER WEEK

AND THERE ARE APPROXIMATELY 4 WEEKS IN A MONTH

SO 414.5*4=1658

SO HE EARNS 1658$ PER MONTH

HELP ME HELP ME PLEASE

Answer:

11126

Step-by-step explanation:

The <em>mean</em> of a set of data is another name for its <em>average</em>. It is the sum of the data, divided by the number of numbers in the sum.

If you use a calculator to help you with the computation of the addition or division, you may as well use the calculator's "mean" function to do the job.

The mean of the given 6 values is their sum, divided by 6. The units of the mean are the same as those of the contributors.

(1117 +1409 +675 +536 +1398 +1621)/6 = 6756/6 = 1126 . . . . degrees F

The mean of the data is 1126 °F.

What does 1/4 of a can of coffee cost if 4 cans of coffee cost $1.60

Arte-miy333 [17]

We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

$4\text{ cans of coffee} = 1.60 \iff \dfrac{4\text{ cans of coffee}}{4} = \dfrac{1.60}{4} \iff 1 \text{ can of coffee} = 0.4$

Now we can simply repeat this process again: if we divide both sides by 4, we get

$1 \text{ can of coffee} = 0.4 \iff \dfrac{1 \text{ can of coffee}}{4} = \dfrac{0.4}{4} \iff \dfrac{1}{4}\text{ cans of coffee} = 0.1$
