A farmer grows two types of grain in his fields. He has a seed budget of $17,000.00 and has spent $9,200.00 to plant wheat seed

Helen [10]

Okay so first you have to subtract 17000 from 9200 to see how much money you have left to spend. Then once you get that number, which is 7800, you have to see what's that maximum number of acres that you can get. So you divide 7800 from 41.00 and you can get your answer. Your answer will be 190 acres. 190 acres is the highest you can go without going over budget.

Answer:

<em>x = 30.2 units</em>

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios.

Selecting any of the acute angles, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.

The given right triangle has an angle of measure 51° and its adjacent leg has a measure of 19 units. It's required to calculate the hypotenuse of the triangle.

We use the cosine ratio to calculate x:

$\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}$

$\displaystyle \cos 51^\circ=\frac{19}{x}$

Solving for x:

$\displaystyle x=\frac{19}{\cos 51^\circ}$

$\displaystyle x=\frac{19}{0.6293}$

x = 30.2 units

Uche is a cartographer. He picks a scale to fit a map of India onto a page of an atlas. The page is 121212 by 121212 inches, wit

julsineya [31]

The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: $10.5k= 3214$

The page dimension is:

$Length = 12$

$Width = 12$

The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square

The margin of 0.75 on either sided means the usable dimension is:

$Length = 12 - 2 * 0.75 =10.5$

The dimension of India is:

$Length = 3214$

$Width =2933$

The longest side in India's dimension is:

$Longest = 3214$

From Uche's book, the longest dimension is:

$Longest = 10.5$

So, the scale equation is:

k * longest length of Uche's book = longest side of India

This gives:

$k * 10.5 =3214$

$10.5k =3214$

Find the distance between (-4,-3) and (-8,2)

Masja [62]

The distance (r) between any two points (a,b) and (c,d) is :—

$r = \sqrt{{(a - c)}^{2} + {(b - d)}^{2} }$

Putting the values,

$\sqrt{ {( - 4 + 8)}^{2} + {( - 3 - 2) }^{2} }$

$r = \sqrt{16 + 25}$

$r = \sqrt{41}$

The distance between the points is √41
