My teacher salary in 1996 was $21,129 and in 2019 it was $58,429. What was my percent of change? Round to the nearest tenth.

9514 1404 393

  176.5%

Step-by-step explanation:

The percentage change can be computed from ...

  percent change = ((new value)/(old value) -1) × 100%

  = (58429/21129 -1) × 100%

  = (2.7653 -1) × 100%

  percent change ≈ 176.5%

Additional comment

The average annual increase can be found by taking the root of the ratio, where the root index is the number of years. The percentage increase each year is that root less 1.

  (2.7653^(1/(2019 -1996)) -1 ≈ 4.5% . . . per year for 23 years

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
