Answer: x = 20

Step-by-step explanation:

We can use the pythagorean theorem:

x^2 + 15^2 = 25^2

x^2 + 225 = 625

We can subtract 225 from both sides:

x^2 = 400

We can take the square root of both sides:

x = 20.

Maslowich

Answer:  3 is the weighted average

Step-by-step explanation:

A weighted average is sort of like it sounds. - Different data-points are given different weights as far as how much they affect the answer. It's like you had 4 people on a corporation's board and all four get to vote, but their votes count differently. Person A has a vote that counts as 3. Person B has a vote that counts as 2 votes. Persons C & D each have a vote that counts as just one vote. For peron A to get outvoted, all the others must gang up against him.

Okay, back to our actual problem ...

  • point E measures (-1) and has weight 2x weight of F
  • point F has a measure of 2 and no particular stated weight
  • point G measures 6 and has a weight of 3x weight of F

Since we can assign a weight to point F and the other weights will be based on that, let's just keep it simple and give point F a weight of 1.

That gives E a weight of 2, and G a weight of 3.

So, ...

E value times E weight is   (-1)   x   2 = -2

F value times F weight is      2   x   1 =   2

G value times G weight is   6   x   3 = 18

          Sum of (value x weight)  =  18

          Sum of the weights = 2 + 1 + 3 = 6

WE get the weighted average by taking the sum of (value x weight) products (18) and then dividing by the sum of the weights (6).

18/6 = 3, the weighted average

The point at coordinate 3 represents the weighted average.

Solve the equation and enter the value of x below 2(x+6)=-10
malfutka [58]

Answer:

\huge \boxed{x=-11}

Step-by-step explanation:

First, divide by 2 from both sides of equation.

\displaystyle \frac{2(x+6)}{2}=\frac{-10}{2}

Then, solve.

\displaystyle x+6=-5

Subtract by 6 from both sides of equation.

\displaystyle x+6-6=-5-6

Solve to find the answer.

\displaystyle x=-11, which is our answer.

An airplane takes off from an airport. When the
Ivanshal [37]

The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft

<h3>Calculation of the distance travelled</h3>

  • To calculate the angle of elevation of the airplane

tan x° = opposite/adjacent

where opposite = 16,500 feet

adjacent = 6,000 ft

tan x° = 16,500 / 6,000

tan x° = 2.75

X = arctan ( 2.75)

X = 70°

  • To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.

C² = a² + b²

C² = 16,500² + 6,000²

C² = 272250000 + 36000000

C² = 308250000

C= √308250000

C= 17,557ft
