Answer:

$317.475 is the selling price for the painting

Step-by-step explanation:

First find the area of the painting, A= lw; 22.5 inches×34 inches = 76.5 in²

You are given the cost per square inch is $4.15, therefore multiply

76.5 ×4.15 = $317.475 or if you need to round to whole number $317.

A sample of lake water contains 150grams of salt. If 30% of the water sample is salt, find the number of grams the entire sample
hjlf

Answer:

500 grams

Step-by-step explanation:

Let's say that the total number of grams of the sample is x. We know that 30% of x is salt and we also know this quantity is 150 grams. So, we can write this as:

30% * x = 150

Remember that % is simply "out of 100", so 30% = 30/100 = 0.30. Then:

0.30 * x = 150

Divide both sides by 0.30:

x = 500 grams

Hope this helps!

Classify the sequence arithmetic , geometric, or neither
Feliz [49]

Answer:

Geometric

Step-by-step explanation:

Given terms are {3, -1, 1/3, -1/9............}

If we have common difference between the terms then it is arithmetic

If we have common ratio between the terms then it is Geometric

Difference of 3  and -1  is 4

Difference of 1/3  and -1 is -4/3

Common difference it not same so it is not Arithmetic

Now we check common ratio

we divide second term by first term

first term is 3  and second term is -1

\frac{-1}{3}

now we check with next two terms

\frac{\frac{1}{3}}{-1}=\frac{-1}{3}

common ratio is -1/3

So this is Geometric
