Answer:

30√74 ft or 258.070 ft rounded to three decimal places.

Step-by-step explanation:

To find the length of a diagonal, add the square of the width and the square of the length together and find the square root of the sum.

d = √210² + 150²

d = √44100 + 22500

d = √66600

d = 258.069758 ft (This is the answer I got in six decimal places. Rounding it to three, as it says in the question, would be 258.07 ft, as 7 is greater than 5 (the third digit was 9 by the way).)

An exact answer to that, in radical form, is 30√74 ft.

Answer:

66600 ft

Step-by-step explanation:

First draw a rectangle and draw a diagonal line in the middle. The line makes two triangles, and the line itself is the hypotenuse. So, to find hypotenuse, the formula is:

a^2 + b^2 = c^2

The variable c defines the hypotenuse. Therefore:

a = 150

b = 210

Let's solve:

150^2 + 210^2 = c^2

22500 + 44100 = c^2

66600 = c^2

Therefore, in conclusion, the result we are getting is 66600 ft.

Given points A (-8,7) and B (6, -9), find the midpoint, M
Vladimir [108]

Hey there! I'm happy to help!

To find the x value of the midpoint, you add the 2 x values and divide by 2.

-8+6=-2

-2/2=-1

For the y value, you do the same thing but with the y values.

7-9=-2

-2/2=-1

Therefore, our midpoint is (-1,-1).

Have a wonderful day! :D

The sides of a triangle have lengths x + 3, 4(x - 13), and 3 over 4 x. The perimeter of the triangle is 3x +6. What is the lengt
nignag [31]

Answer:

shortest side = 15

Step-by-step explanation:

The question is a bit ambiguous. Do you mean (3/4) x or do you mean 3/(4x)?

I'll take it to be the first one.

(x + 3) + 4(x - 13) + (3/4)x = 3x + 6    Remove the brackets on the left

x + 3 + 4x - 52 + 0.75 x = 3x + 6      Combine

5.75x - 49 = 3x + 6                           Subtract 3x from both sides.

2.75x - 49 = 6                                     Add 49 to both sides

2.75x = 55                                          Divide by 2.75

x = 55/ 2.75

x = 20

Now for the shortest side

x + 3 = 23

4(x - 13) = 4(20 - 13) = 4*7 = 28

(3/4)*20 = 15

The shortest side = 15
