Answer:

  • x = 4

Step-by-step explanation:

x has the same value as RT since they are equal sides of the isosceles triangle.

RT is also the hypotenuse of ΔRST - 30°×60°×90° right triangle.

Acoording to the property of such triangles, the ratio of sides is:

  • a : b : c = 1 : √3 : 2

We have:

  • b = 2√3 and c = RT

Use the ratio to find the lenght of RT

  • 2√3 : RT = √3 : 2
  • RT = 2*2√3/√3
  • RT = 4

So the value of x is 4 units

Whats the difference between "6 + A" and "6 x A"
Nata [24]

Answer:

To determine what is the difference between "6 + A" and "6 x A", the logic of the proposed mathematical operations must be explained:

In "6 + A", the value A is added to the initial value 6. Thus, for example, if A were worth 10, to the initial value 6 10 units are added, with which the final value is 16.

In contrast, in "6 x A", the initial value 6 is multiplied by as many times as the value A indicates. Therefore, continuing with the value of A as 10, in this case 6 would be multiplied by 10 times, giving a final value of 60.

This sample makes the most sense because it is a majority of everyone, not just a majority of certain people. Also, Mountain School would get fewer complaints from other people if they went with a majority of 75%. Finally, running sports usually cost less then other sports.

if a pound of grapes cost $0.14 in 1960 and the price of grapes increased at the same rate as the CPI from 1960 to 1980 by appro
masya89 [10]

The CPI increased from 29.6 to 82.4.  

The rate of increase, is:

82.4/29.6 = 2.78

Now multiply this rate to the $0.14 price of grapes from 1960.

$0.14 x 2.78 = $0.39

Now to get the amount of increase subtract the new price from the original price:

$0.39 - $0.14 = $0.25 increase.

Use ordered pair rule(x,y) (x-4,y+8) to find the preimage of (8,20)
natka813 [3]

Answer:

(12,12)

Step-by-step explanation:

For the x coordinate you add 4 to 8, and get 12.

For the y coordinate you subtract 8 from 20 to get 12.

So it would read (x + 4, y -8) -> (12,12)
