In a 30°-60°-90° triangle, the length of the hypotenuse is 30. Find the length of the longer leg.

Assoli18 [71]

In a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
The shorter leg is the side opposite the 30 degree angle, therefore
the shorter leg = 30/2 = 15

By the Pythagorean theorem
the longer leg = √(30² - 15²) = √(900-225) = √675 = 15√3 ≈ 25.98 units

Max estimate the link of his garden to be 25 feet do you estimate it to be 70 if they actually is 19 feet which is a better esti

I think it would be better to round to 25 because it's closer to 19. Srry if u get it wrong. Hoped I helped:D

Write an equation of the line passing through each of the following pairs of points.

ira [324]

$\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{-3}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{7}}}{\underset{run} {\underset{x_2}{-6}-\underset{x_1}{5}}}\implies \cfrac{-10}{-11}\implies \cfrac{10}{11}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{7}=\stackrel{m}{\cfrac{10}{11}}(x-\stackrel{x_1}{5})\implies y-7=\cfrac{10}{11}x-\cfrac{50}{11} \\\\\\ y=\cfrac{10}{11}x-\cfrac{50}{11}+7\implies y=\cfrac{10}{11}x+\cfrac{27}{11}$

A dog breeder plans to mix two types of food to make a mix of low cost

lys-0071 [83]

Answer:

3.75 bags of ChowChow
0.75 bags of Kibble

Step-by-step explanation:

The constraints on protein, minerals, and vitamins give rise to the inequalities ...

40c +30k ≥ 150 . . . . . . required protein

20c +20k ≥ 90 . . . . . . required minerals

10c +30k ≥ 60 . . . . . . . required vitamins

And we want to minimize 10c +12k.

The graph shows the vertices of the feasible region in (c, k) coordinates. The one that minimizes cost is (c, k) = (3.75, 0.75).

To minimize cost, the daily feed should be ...

3.75 bags of ChowChow
0.75 bags of Kibble

Daily cost will be $46.50.
