Stephanie saw in an ad in the paper that her favorite kind of perfume was I feel for 25% off if the sale price was $15 what was
sashaice [31]

Answer: $20

Step-by-step explanation:

Here os the correct question:

Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?

Let the original price of the perfume be y.

Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:

y - (25% of y) = $15

y - (25/100 × y) = $15

y - 0.25y = $15

0.75y = $15

Divide both side by 0.75

0.75y/0.75 = $15/0.75

y = $20

The original price of the perfume is $20

If you know this pls help ):
Aleksandr-060686 [28]
From the right hand side, we will need to find a way to rewriting 3x²y in terms of cube roots.
We know that 27 is 3³, so if we were to rewrite it in terms of cube roots, we will need to multiply everything by itself two more twice. (ie we can rewrite it as ∛(3x²y)³)

Hence, we can say that it's:
 \sqrt[3]{162x^{c}y^{5}} = \sqrt[3]{(3x^{2}y)^{3}} * \sqrt[3]{6y^{d}}
= \sqrt[3]{162x^{6}y^{3+d}}

Hence, c = 6 and d = 2

Find the area of the shaded portion in the equilateral triangle with sides 6.
LUCKY_DIMON [66]
Triangle is equilateral with sides of 6.
Therefore all angles = 60°
Ht of 30-60-90 is 3sr3 = 5.196
Area of 30-60-90 = 1/2×b×h = 3×5.196
Area = 15.59
Pie slice from each corner = 60/360×pi×r^2, with r = 3
1/6×pi×9 = 4.71 × 3 pie slices = 14.13
So, shaded inner region = area triangle - 3 pie corners = 15.59-14.13
= 1.46

Please Help- <br> K + ⅓ = 5 ⅛ | K = ?<br> Show Your Reasoning.
blondinia [14]

Answer:

4\frac{19}{24}

Step-by-step explanation:

I hope I did this right:

So first thing to do is set up the equation.

K + \frac{1}{3} = 5\frac{1}{8}

Next thing to to is subtract 1/3 from both sides to get:

K = 5\frac{1}{8} - \frac{1}{3}

Next up, you will multiply each of the fractions by the opposing value

(multiply 1/8 by 3 and 1/3 by 8)

K = 5\frac{3}{24}-\frac{8}{24}

Alright almost done, by multiplying 24 by 5 you get 120, that will go in the numerator to make the math a lot easier.

K = \frac{123}{24}-\frac{8}{24}

Finally, you subtract 123 over 24 by 8 over 24.

K = \frac{123}{24} - \frac{8}{24} = \frac{115}{24}

Then just simplfy the 115/24 to get

4\frac{19}{24}
