For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

jekas [21]

The sum of the interior angles in the polygon whose side is 10 is $1440^{0}$

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × $180^{0}$

S0, n=10

Then, sum of interior angle be = (n-2) x 180

= (10-2) x 180

= 8 x 180

$= 1440^{0}$

Thus, the sum of the interior angles in the polygon is $1440^{0}$

What values of c and d make the equation true?

saul85 [17]

Answer:

Third option.

Step-by-step explanation:

You need to cube both sides of the equation. Remember the Power of a power property:

$(a^m)^n=a^{mn$

$\sqrt[3]{162x^cy^5}=3x^2y(\sqrt[3]{6y^d})\\\\(\sqrt[3]{162x^cy^5})^3=(3x^2y(\sqrt[3]{6y^d}))^3\\\\162x^cy^5=27x^6y^36y^d$

According to the Product of powers property:

$(a^m)(a^n)=a^{(m+n)$

Then. simplifying you get:

$162x^cy^5=162x^6y^{(3+d)}$

Now you need to compare the exponents. You can observe that the exponent of "x" on the right side is 6, then the exponent of "x" on the left side must be 6. Therefore:

$c=6$

You can notice that the exponent of "y" on the left side is 5, then the exponent of "x" on the left side must be 5 too. Therefore "d" is:

$3+d=5\\d=5-3\\d=2$

If the unit selling price is $2.50 and the unit cost is $1.00, what action is needed to maintain the gross margin percentage whe

harina [27]

Of course you need to know what "gross margin percentage" means. Roughly speaking it is the profit as a percentage of sale price. When a unit costs $1.00 and is sold at $2.50 the excess revenue is $1.50 Although we could express this profit margin as a FRACTION of the sale price, (so this would be 1.50/2.5 = 3/5), it is usual to state this as a PERCENTAGE. The gross margin percentage in the original case would be 100 * 3/5 = 60% Let cost price be c, sale price be s. Gross margin percentage g = 100* (s - c)/s Solving this for sale price s s = c/[1 - (g/100)] When unit cost increases $0.25 we have c = 1.25 so s = 1.25[1 - 0.6] = 1.25/0.4 = 3.1 Action needed to maintain the gross margin percentage is to increase selling price to $3.10
