We fill in the following formula:
\frac{part}{total}  \times 100\%

So in this case we get
\frac{17}{20}  \times 100\% = 85\%

Therefore the answer is 85%

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest<br> inch.
dalvyx [7]

Given:

In triangle GHI, h = 300 inches, G=30° and H=29º.

To find:

The length of i.

Solution:

We have, G=30° and H=29º.

Using angle sum property, we get

m\angle G+m\angle H+m\angle I=180^\circ

30^\circ+29^\circ+m\angle I=180^\circ

59^\circ+m\angle I=180^\circ

m\angle I=180^\circ-59^\circ

m\angle I=121^\circ

According to Law of sines,

\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}

Using Law of sines, we get

\dfrac{h}{\sin H}=\dfrac{i}{\sin I}

\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}

\dfrac{300}{0.4848}=\dfrac{i}{0.8572}

Multiply both sides by 0.8572.

\dfrac{300}{0.4848}\times 0.8572=i

530.44554=i

i\approx 530

Therefore, the length of i is about 530 inches.

A rectangle has a height of b3 + b2 and a width of b2 + 76 + 4.
zaharov [31]

Answer:

The area is:

{b}^{5}  + 8 {b}^{4}  + 11 {b}^{3} +  4 {b}^{2}

Step-by-step explanation:

To find the area of a rectangle, multiply the width by the height (I'll be using x for b, as it is easier when writing the equations):

a =  ({x}^{ 3}  +  {x}^{2} )( {x}^{2}  + 7x + 4) \\ a =  {x}^{5}  +  7{x}^{4}  + 4 {x}^{3}   \\ +  {x}^{4}   + 7 {x}^{3}  + 4 {x}^{2}  \\ a =  {x}^{5}  + 8 {x}^{4}  + 11 {x}^{3} +  4 {x}^{2}
