Answer:

69.282 m

Step-by-step explanation:

We can use the trigonometry of right triangles to solve this, since we are in the presence of a right triangle with acute angle 30 degrees, opposite side unknown (the vertical height of the cliff), and adjacent side equal to 120 m.

we use the tangent function to solve for the unknown, as shown below:

tan(30) = x/120

x = 120 * tan(30) = 69.282 m

Answer:

[tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Step-by-step explanation:

Given: During [tex]24[/tex] hours a radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music, [tex]\frac{2}{3}[/tex] playing hip hop, and the rest playing dance music.

To find: How much time is spent playing dance music?

Solution:

We have,

Radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music.

Radio station spends [tex]\frac{2}{3}[/tex] of the time playing hip hop.

Radio station spends rest of the time playing dance music.

So,

Time spend on playing rock music [tex]=\frac{1}{5}\times24 = 4.8\:\text {hours}[/tex]

Time spend on playing hip hop [tex]=\frac{2}{3}\times24 = 16\:\text {hours}[/tex]

Now, total time radio station spends on all the three music is [tex]24[/tex] hours.

Therefore, rest of the time[tex]=24-(16+4.8)=3.2\:\text{hours}[/tex]

It is given that in the rest of the time, the radio station plays dance music.

Hence, [tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Answer: w^6/9

Step-by-step explanation:

first, i evaluated the powers.

3^-2 x 1 x 1/w^-6

then, i calculated those products.

3^-2/w^-6

then, i just expressed it with a positive exponent.

w^6/3^2

finally, i evaluated that.

w^6/9

Answer: y = -2 + 3/2x

Step-by-step explanation:

1. 3x - 2y = 4 (move the variable to the right of the equal)

1.1. -2y = 4 - 3x

2. y = -2 +3/2x (divide both sides by -2)

The solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

WE have been given an expression as

-3p-2r / 6+4s

We have to substitute the value p = 1, r= -7, and s = -2 to find the solution.

Plug the values;

-3p-2r / 6+4s

-3 (1) -2 (-7) / 6+4(-2)

-3 + 14 / 6 - 8

11 / -2

Hence, the solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2

Answer: 0.129

Step-by-step explanation:

Coach Collin's soccer team selected 16 girls from 124 girls who tried out for the team.

The fraction of girls selected to those who tried out in fraction form is:

= 16/124

The decimal form will be:

= 16 ÷ 124

= 0.129

Answer:

x= number of songs bought

y= number of movies bought

1.75*x + 2.5*y = 45

x + y = 20

Step-by-step explanation:

Giving the following information:

Robert spent $45 buying songs and movies at an online store that charges 1.75 for each song and $2.50 for each movie he purchased a total of 20 songs and movies combined.

We need to establish a system of equations that represents this situation.

x= number of songs bought

y= number of movies bought

1.75*x + 2.5*y = 45

x + y = 20

Now, we can determine the x and y:

x= 20 - y

Substitute x:

1.75*(20 - y) + 2.5y = 45

35 - 1.75y + 2.5y = 45

0.75y = 10

y= 13

x= 20 - 13

x= 7

Prove:

1.75*7 + 2.5*13 = 45

7 + 13 = 20
