15. 99%, 0.95, 5/9, 9.5%
Make all decimals: .99, .95, .55, .095
List: Zero is less than 9 or 5 so it's first than 5 and than 9, you have two 9's so 5 is less than 9: .095, .55, .95, .99

16. 3/8, 50%, 0.35, 38%
Same steps: .375, .50, .35, .38
3 is less than 5 and 5 is less than 8 or 7 so: .35, .375, .38, .5

And do the same thing for the other two problems :)

14=-(p-8) <br> how do i find p

Xelga [282]

Answer:

p=-6

Step-by-step explanation:

14 = -(p-8) (distribute negative into parentheses)

14 = p(-1) -8(-1)

14 = -p + 8 (subtract 8 from both sides)

14 - 8 = -p

6 = -p (multiply both sides by -1 and rearrange)

p = 6(-1) = -6

Making a good purchasing decision requires?

KiRa [710]

Answer:

All of the above

Step-by-step explanation:

Making a good purchasing decision requires comparing the prices of similar items,

reading reviews of the product and waiting until the product is on sale, if possible.

For a consumer to make the best purchasing decision, he needs to compare the prices of similar product or substitute so as to maximize utility. The aim to buy a good quality product at less price.

The Consumer also needs to read the review of the product made by previous users of the product. This is to ensure that he makes he doesn't make the mistake of purchasing low quality product.

He also needs to wait until the product is on sale before deciding on purchasing it. This is to there is no regret of purchasing a product that is of low quality later in the future.

M=(3x)/(pi r^(2)h)<br><br> solve for "r"

wel

The solution for r in the given equation is r = √[(3x)/(pi h)(m)]

<h3>How to determine the solution of r in the equation?</h3>

The equation is given as:

m = (3x)/(pi r^(2)h)

Multiply both sides of the equation by (pi r^2h)

So, we have:

(pi r^(2)h) * m = (3x)/(pi r^(2)h) * (pi r^(2)h)

Evaluate the product in the above equation

So, we have:

(pi r^(2)h) * m = (3x)

Divide both sides of the equation by (pi h)(m)

So, we have:

(pi r^(2)h) * m/(pi h)(m) = (3x)/(pi h)(m)

Evaluate the quotient in the above equation

So, we have:

r^(2) = (3x)/(pi h)(m)

Take the square root of both sides in the above equation

So, we have:

√r^(2) = √[(3x)/(pi h)(m)]

Evaluate the square root of both sides in the above equation

So, we have:

r = √[(3x)/(pi h)(m)]

Hence, the solution for r in the given equation is r = √[(3x)/(pi h)(m)]
