Answer:

Choice B.  6 km.

Step-by-step explanation:

We see this is a right triangle.

The height of this right triangle is 3 km and the angle adjacent to the height leg of the triangle is  (90 - 26 ) degrees = 64 degrees.

We want the distance d which is the leg opposite  64 degrees.

tan 64 = d / 3 km  ;

d = 3 * tan 64 =  3 * 2.0503038  km  = 6.1509 km

AlladinOne [14]

Answer:

\frac{1024}{2025}

Step-by-step explanation:

\frac{3}{4}^{-4}  = \frac{1}{\frac{3}{4}^{4}  }

(3/4)^4 = 81/256

1 ÷  81/256 = 256/81

So;

\frac{256}{81} * \frac{4}{9} = \frac{1024}{729}

\frac{1024}{729} / n = \frac{1}{9/25}

\frac{1024}{729n} = \frac{25}{9} \\\\n = \frac{1024 *9 }{25 * 729}  = \frac{1024}{2025}

H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.

If he threw it from 95 ft above the ground, the best answer for where he is is on a bridge.
His backyard is at 0 ft (sea level). An underground cave is below sea level. A ladder is probably not 95 ft.

Final answer: D

A number cube is labeled 1 through 6. What is the probability of NOT<br> rolling a 2?
Andre45 [30]

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333
