Answer:

\boxed{Option \ B}

Step-by-step explanation:

In the triangle,

Hypotenuse = 13

Opposite = Perpendicular = 5

Adjacent = Base = 12

Now,

Cos B = \frac{Adjacent}{Hypotenuse}

Cos B = 12/13

If the triangle is just like in the attached file!

the height of the snow was 84 inches in the beginning of the week. it melts at a rate of 0.15 inches per hour. how many hours wo
lakkis [162]

Answer:

It takes 147 hours for the snow to reach 62 inches.

Step-by-step explanation:

Given:

Height of the snow at the beginning  = 84 inches

Rate at which the snow melts = f 0.15 inches per hour

To Find:

The time taken for the  snow to reach 62 inches = ?

Solution:

Let the time taken to reach 62 inches be x

Then according to the question,

Total height of the snow - (rate of melting)(x) = 62 inches

On substituting the values,

84 - (0.15)(x) = 62

84 - 0.15x = 62

- 0.15x = 62 - 84

- 0.15x = -22

0.15x = 22

x = \frac{22}{0.15}

x= 146.6

x = 147

Express (16^3)^1/2 <br> in simplest radical form.
Rufina [12.5K]

Answer:

I assume you mean 16^(1/3) i.e. the cube root of 16

I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.

Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3

You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2

0.27 recurring as a fraction please
natali 33 [55]

Answer:

\frac{3}{11}

Step-by-step explanation:

assuming the recurring digits are 0.272727.... , then

we require 2 equations with the repeating digits placed after the decimal point.

let x = 0.2727.... (1) ← multiply both sides by 100

100x = 27.2727... (2)

subtract (1) from (2) thus eliminating the repeating digits

99x = 27 ( divide both sides by 99 )

x = \frac{27}{99} = \frac{3}{11} ← in simplest form

melisa1 [442]

The two angles are vertical angles, which means they are the same.

Set the two equations to equal and solve:

2x +2 = 3x -52

Subtract 2x from each side:

2 = x -52

Add 52 to each side:

x = 54
