Work out the area of 5e parallelogram

Answer: The area is 268 cm squared (approximately)

Step-by-step explanation: The area of a parallelogram is given as ;

Area = b x h

Where b is the base and h is the vertical height. However the vertical height is not given, so we shall apply the trigonometric ratio to determine the vertical height. If we draw a straight line from the the top right vertex down to the base, we would have constructed a right angled triangle with hypotenuse 13cm, and reference angle 79 degrees. We can now calculate the vertical height as follows;

Sin 79 = opposite/hypotenuse

Sin 79 = h/13

By cross multiplication we now have

Sin 79 x 13 = h

0.9816 x 13 = h

12.76 = h

With the vertical height now known, we can calculate the area as follows

Area = b x h

Area = 21 x 12.76

Area = 267.96 cm squared

What is the following product

Genrish500 [490]

For this case we must find the product of the following expression:

$\sqrt [3] {5} * \sqrt {2}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

We rewrite the expression using the lowest common index of 6, then:

$5 ^ {\frac {1} {3}} * 2 ^ {\frac {1} {2}} =$

We rewrite the terms in an equivalent way:

$5 ^ {\frac {2} {6}} * 2 ^ {\frac {3} {6}} =$

We rewrite the expression using the property mentioned:

$\sqrt [6] {5 ^ 2} * \sqrt [6] {2 ^ 3} =$

We combine using the product rule for radicals:

$\sqrt [n] {a} * \sqrt [n] {b} = \sqrt [n] {ab}$

So:

$\sqrt [6] {5 ^ 2 * 2 ^ 3} =\\\sqrt [6] {25 * 8} =\\\sqrt[6]{200}$

Given the explicit formula an = 125 + 18(n - 1), find the 49th term.

RideAnS [48]

125+ 18( 49-1 )
=125 + 18( 48)
=125 +864
=989
The 49th term is 989

Devin made 30 custom t-shirts to sell.He will donate 1/8 0f his total sales to a local charity. He sold all 30 t-shirts for $18

V125BC [204]

Answer:

Devin will donate <u>$67.5</u> to charity.

Step-by-step explanation:

Given:

Devin made 30 custom t-shirts to sell.

He will donate 1/8 0f his total sales to a local charity.

He sold all 30 t-shirts for $18 each.

Now, to find the amount Devin donate to charity.

Total number of t-shirts = 30.

Each t-shirts sold at = $18.

So, total amount of 30 t-shirts sold:

$30\times 18$

$=\$540.$

As, Devin will donate $\frac{1}{8}$ of his total sales to a local charity.

Now, to get the amount he will donate to charity:

$\frac{1}{8} \ of\ \$540\\\\=\frac{1}{8} \times 540\\\\=\frac{540}{8}\\\\=\$67.5.$

Therefore, Devin will donate $67.5 to charity.
