Hey. Let me help you on this one.

In order for us to solve this problem, we will need to determine how much money Luke has earned from the sales this month, and find the total amount of sales in dollars.

I will also be attaching an image to this answer in case you still don't understand the question, or need extra help with your studies.

We know that Luke's salary is $3500, and anything above that amount of money comes from sales he makes. We also know that he only gets 15% from sales. Let's determine how much he earned from sales this month.

$4760-3500=1260$

Luke has earned $1260 from the sales he made. Since it's only 15% of the full amount, we need to convert this value to 100%. We can do this by finding 1% of the unknown number, and multiplying it by 100 to show the full amount of sales.

Let's find 1% of the total amount of sales. Since 1260 is 15% of the unknown total, let's divide it by 15.

$\frac{1260}{15} =84$

Great. $84 is 1% of the total amount of sales. All we need to do is multiply it by 100 to show 100% of the total amount of sales.

$84*100=8400$

Awesome. We now know the amount of sales in dollars that Luke has brought to the company.

Answer: Total amount of Luke's sales in dollars is $8400

ASAP! GIVING BRAINLIEST! Please read the question THEN answer correctly! No guessing.

Answer:

A. m = $\frac{F}{a}$

Step-by-step explanation:

The variables "ma" are connected, implying they are together through multiplication. To remove "a" from "m," you must do the opposite, which is division. So, divide both sides by "a," like so:

F = ma

$\frac{F}{a} =\frac{ma}{a}$

$\frac{F}{a}$ = m

If 3 pistachio and 1 walnut weigh the same as 10 peanuts, and 1 pistachio and 6 peanuts weigh the same as 1 walnut, how many pea

yuradex [85]

Answer:

7

Step-by-step explanation:

We need to translate all these statements to equations.

First of all, let P be the pistachios, W the walnuts and N the peanuts.

The first statement "3 pistachio and 1 walnut weigh the same as 10 peanuts" can be represented as:

3 P + 1 W = 10 N

The second statement "1 pistachio and 6 peanuts weigh the same as 1 walnut" can be represented as:

1 P + 6 N = 1 W

If we notice, both equations have a similar term: 1 W. The second gives us the equivalence to the weight of 1 walnut, whereas in the first we have the weight of 1 walnut as an unknown variable. Lets replace it!

3 P + 1 W = 10 P

3 P + (1 P + 6 N) = 10 P

4 P + 6 N = 10 P

We now need to sum (-4P) in both sides to eliminate the 4 P on the left:

4 P + 6 N - 4P = 10 P - 4 P

6 N = 6 P

Dividing both sides by 6:

N = P

Now we need an equation that relates walnuts to peanuts. Lets replace N=P on our firts equation:

3 P + 1 W = 10 P

3 N + 1 W = 10 N

Summing (-3 N) in both sides:

3 N + 1 W - 3N = 10 N - 3N

1 W = 7 N

So, 1 walnut weights the same that 7 peanuts

Is √6/8. rational or irrational?

Ipatiy [6.2K]

<h2>Answer:</h2>

The number is irrational.

<h2>Step-by-step explanation:</h2>

<h3>1. Convert to decimal.</h3>

$\sqrt{\frac{6}{8} } =\sqrt{0.75} =0.8660254038...$

<h3>2. Conclude.</h3>

Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is irrational.

-------------------------------------------------------------------------------------------------------

Note. In case the number expressed in the question was $\frac{\sqrt{6} }{8}$ , the answer would still be irrational, for the same reasons explained above.
