Angles A and B are the acute angles of a right triangle. If the tangent of A is 2.1445, then angle B measures

lina2011 [118]

Tan A = 2.1445
A = tan^(-1) 2.1445 = 64.999 ≈ 65°
In a right triangle:
A + B = 90°
65° + B = 90°
B = 90° - 65° = 25°
Answer:
A ) 25°

Factor x3y6 + 27z42. (xy3 + 3z39)(x2y9 – 3xy3z39 + 9z1,521) (xy3 + 3z39)(x2y6 – 3xy3z39 + 9z78) (x3y6 + 27z42)(x6y12 – 27x3y6z42

Licemer1 [7]

Answer:

$x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})$

Step-by-step explanation:

Given

$x^3y^6 + 27z^{42$

Required

Factor

Express both terms as a cube

$x^3y^6 + 27z^{42} = (xy^2)^3 + (3z^{14})^3$

Let

$a =(xy^2)$

$b = (3z^{14})$

So:

$x^3y^6 + 27z^{42} = a^3 + b^3$

Using sum of cubes:

$a^3 + b^3 = (a + b)(a^2 - ab + b^2)$

So:

$x^3y^6 + 27z^{42} = (a + b)(a^2 - ab + b^2)$

Substitute in, values of a and b

$x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})((xy^2)^2 - (xy^2)*(3z^{14}) + (3z^{14})^2)$

$x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})$

A store paid $12 for a sweatshirt and sold the sweatshirt of $19.20. What was the percent markup (increase) of the sweatshirt? *

Nookie1986 [14]

The percent markup of the sweatshirt is 60%

Here, we want to calculate the percenatge of profit made by the store

Mathematically;

$\text{Percentage markup = }\frac{(sales\text{ price-cost price)}}{\cos t\text{ price}}\text{ }\times\text{ 100\%}$

From the question, we can deduce the following;

cost price is the price the store bought the sweatshirt = $12

sales price is the amount in which they sold the sweatshirt = $19.20

Thus, we proceed to substitute these values into the markup equation above;

$\begin{gathered} \text{Perecentage markup = }\frac{(19.20-12)}{12}\text{ }\times\text{ 100\%} \\ \\ \text{Percentage markup = }\frac{7.20}{12}\text{ }\times\text{ 100\%} \\ \\ =\text{ 60\%} \end{gathered}$
