Tatiana [17]

Answer:

Step-by-step explanation:

Set 1: 12, 8, 6, 4, 10,1

Now find mean of 6 and 4:

(6+4)/2=10/2:

5 << answer of set 1

Set 2: 6,3,5, 11, 2, 9,5,0

(11+2)/2=6.5

Set 3: 30, 16, 49, 25

(16+49)=65/2

32.5

A kite flying in the air has a 12 - ft line attached to it. its line is pulled taut and casts a 10 - ft shadow. find the height

tekilochka [14]

The height of the kite will be 6.6 ft rounded to the nearest tenth.

Explanation

According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.

The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft

Now, in right angle triangle ABC, using Pythagorean theorem....

$(AB)^2 +(BC)^2 = (AC)^2 \\ \\ (AB)^2 +(10)^2 = (12)^2 \\ \\ (AB)^2 +100 = 144\\ \\ (AB)^2 = 144-100 =44\\ \\ AB=\sqrt{44}= 6.6332....$

So, the height of the kite will be 6.6 ft rounded to the nearest tenth.

A hardware store rent vacuum cleaners that customers for part or all of A day before returning. The Store charges a flat fee Plu

Pavel [41]

Answer:

Step-by-step explanation:

Let x represents the amount that the customer pays per hour

for renting the vacuum cleaner before returning it.

Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.

Let F represent the amount that the store charges a customer for renting the vacuum cleaner for x hours.

A linear function F for the total retail cost of a vacuum cleaner would be

F(x) = x + y

If the customer rents it for n hours, the total amount becomes

F(x) = nx + y

What is the distance to the earth’s horizon from point P?

Klio2033 [76]

The distance to the earth’s horizon from point P is 281.6 miles

<h3>How to determine the distance to the earth’s horizon from point P?</h3>

The tangent line from P meets the radius of the earth at a right angle.

This means that the triangle is a right triangle.

The length of x is then calculated as:

(3959 + 10)^2= 3959^2 + x^2

Rewrite as:

x^2 = (3959 + 10)^2- 3959^2

Evaluate

x^2 = 79280

Take the square root of both sides

x = 281.6

Hence, the distance to the earth’s horizon from point P is 281.6 miles
