Your friend's distance from her starting point to your position is decreasing until she passes by you. This distance is D(t) = 100 ft - (20 ft / sec)t. We'll assume that your friend doesn't actually pass by you; she just gets closer and closer, from her initial 100 ft distance from you. Then:
D(t) = 40 ft = 100 ft - (20 ft / sec)t. Simplifying, we get:
-60 ft = -(20 ft / sec)t, and thus t = 3 sec.
Opposite angles in a parallelogram have to be equal so

Answer:
11. 2/5 = <u>40</u>/100 = <u>40</u>% 12. 29/50 = <u>58</u>/100 = <u>58</u>%
Step-by-step explanation:
To convert the given fraction to a fraction of 100, cross-multiply and divide.
2 × 100 = 200 / 5 = 40
Then, whenever you have a number over 100, all you need to do to get the percentage is find the numerator and add a percent sign at the end of the number.
40 ⇒ 40%
Repeat this with the second question.
29 × 100 = 2900 / 50 = 58 ⇒ 58%
Answer:
The value of car after n years at the depreciation rate is $ 50,000 .
Step-by-step explanation:
Given as :
The cost of the car that Jill bought = $ 50,000
The depreciation rate of car value = r = 10 % a years
Let The car after n years of depreciation = $ A
Now, According to question
The cost of car after n years of depreciation = initial cost of car ×
Or, $ A = $50,000 ×
Or, $ A = $50,000 ×
Or, $ A = $50,000 ×
I.e $ A = $50,000 ×
So, value of car after n years = $ 50,000
Hence The value of car after n years at the depreciation rate is $ 50,000 . Answer
