Answer 1

Answer:

  (x, y) = (4, 10)

Step-by-step explanation:

The coefficients of y are opposites, so the y-terms can be eliminated by adding the equations.

  (8x -5y) +(2x +5y) = (-18) +(58)

  10x = 40 . . . . . . simplify

  x = 4 . . . . . . . . . divide by 10

Substituting this into the second equation gives ...

  2(4) +5y = 58

  5y = 50 . . . . . . . . subtract 8

  y = 10 . . . . . . . . . .divide by 5

The solution is (x, y) = (4, 10).

Answer:

30%

Step-by-step explanation:

3/10=30/100 and 30/100 is the same as 30%

because %'s mean out of 100 so 30% means 30 out of 100 which can be simplified to 3 out of 10 or 3/10 (so its all equal)

Find the approximate length of the line AB PLZZZZZZZZZZZZZZZZZZ HELPPPPPP

Answers

Answer:

Approximate length of line AB is 8.6

Step-by-step explanation:

Input Data :

Point 1 (xA, yA) = (8, 2)

Point 2 (xB, yB) = (3, 9)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB − xA) ^2 + (yB − yA)^2

Solution :

Distance between two points = √(3 − 8) ^2 + (9 − 2) ^2

= √(−5) ^2 + 7^2

= √25 + 49

= √74

= 8.6023

Distance between points (8, 2) and (3, 9) is 8.6023

hope this helps and is right :)

Answer:

First choice

12.0

Step-by-step explanation:

Make a right triangle, drawing straight lines, down from point A and left from point B. Use the pythagorean theorum to solve.

I will use "x," "y," and "z" as sides of the triangle as to not confuse between points a and b.

Line AB is line z

x^2 + y^2 = z^2

8^2 + 9^2 = z^2

64 + 81 = z^2

145 = z^2

(find square roots of both)

12.0416 = z

A 40-meter-long blade of a wind turbine makes one complete revolution in 10 seconds. To the nearest tenth, the linear velocity of the blade is meters per second.

Answers

Answer:

25.13 m/s

Step-by-step explanation:

Linear velocity = Distance / time

The distance = Circumference of turbine = 2πr

Radius, r = 40 m

Circumference= 2 * π * 40 = 251.327

The linear velocity is thus :

Circumference / time

= 251.327m / 10s

= 25.13 m/s

The diagram shows a regular polygon
What is the value of x?
How do I solve this

Answers

Answer: x=120°

Step-by-step explanation:

What you are looking for is the value of the exterior angle of the regular polygon.

For a n-sided regular polygon, the external angle is given by the formula 360°/n.

Because the shape in this example is a regular triangle, the value of n is 3.

360°/n

=360°/3

=120°

Therefore, x=120°

Find the value of x by finishing solving the system shown below.

Answers

Answer:

x = 10

Step-by-step explanation:

Since both equations give y in terms of x, equate the right sides

3x - 28 = - 2x + 22 ( add 2x to both sides )

5x - 28 = 22 ( add 28 to both sides )

5x = 50 ( divide both sides by 5 )

x = 10

how do you solve something like this?

Answers

Answer:

to find the value of x have to know that they would all add up to 180 degrees. so subtract 98 from 180. then you would have to find the angel of the part on the left.

Step-by-step explanation:

Answer:

X = 41

Step-by-step explanation:

this triangle is isosceles triangle, so

X + X + 98 = 180 ( being triangle)

2X + 98 = 180

2X = 82

therefore : X = 41
