Andy was correct
2639456 is rounded to 2640000 because the 9 from 39,456 rounds up to 0 and the three changes to a 4
Elizabeth rounded down instead
In order to fully understand the problem, it is best to sketch it. Sketching the system, we will see that the system forms a triangle where the angle of elevation is 36 degrees. We are asked to find the hypotenuse. We can use a trigonometric function. It should be noted that one of the sides should also be given in order to calculate the hypotenuse. Trigonometric functions that can be used are:
sin(theta) = opposite / hypotenuse
cos(theta) = adjacent / hypotenuse
Ellie: 20*15=300
Heather: 18*18= 324
Heather's floor model is greater by 24 feet
Answer:
8859.5
Step-by-step explanation:
if it decreases with 35% then after each year it is worth only 75% of its previous value. so after one year it is worth 75%*21000=15750. the next year it is 75%*15750=11812.2. and after the 3rd year itnis worth 75%*11812.2=8859.5
