Answer:
That number is 0.45
Step-by-step explanation:
3/5x = 2x - 63/100
0.63 = 2x - 3/5x
0.63 = 10/5x - 3/5x
0.63 = 7/5x
7x = 0.63*5 = 3.15
x = 3.15/7
Answer:
Step-by-step explanation:
<u>Proportional relationship:</u>
<u>Given:</u>
<u>Find k:</u>
This question needs more information like where point E is but I'm going to assume that point E is directly below point D
With that assumption, angle EDF should be (90°- 25°) which is 65°
tan 65° = opposite/adjacent
tan 65° = 10 yd/ DE
DE = 10 yd/tan 65°
DE = 4.7 yd (to the nearest tenth)
Remember to include a picture next time for greater clarity :)
Rate of growing, r = 91.2/90 = 1.013
Salary, f(x) = Initial salary * (r)^ (years from 2005)
f(x) = 90(1.013)^x.
This is the second option.
