Answer:
170,070 residents
Step-by-step explanation:
Original population = 1500 residents
Total population after 6 years is calculated using the formula
A = P(1+r)^t
r is the rate = 120% = 1.2
t is the time = 6 years
P is the original population
A = 1500(1+1.2)^6
A = 1500(2.2)^6
A = 1500(113.379904)
A = 170,069.856
Answer:
3xyz
Step-by-step explanation:
The required sum = 7xyz+(−5xyz)+9xyz+(−8xyz)
=7xyz–5xyz+9xyz–8xyz
=(7–5+9–8)xyz
=(16–13)xyz
=3xyz
Answer:
88%
Step-by-step explanation:
There are 67 questions on an exam
You miss 8 questions
The first step is to calculate the number of correct questions
= 67-8
= 59
Therefore the grade can be calculated as follows
= 59/67 × 100
= 0.880 × 100
= 88%
Hence the grade is 88%
Using the relation of similar triangles...
(12 + 4)/6x = 12/(5x -2)
16/6x = 12/(5x - 2)
8/3x = 12/ (5x -2)
8(5x - 2) = 12(3x)
40x - 16 = 36x
40x - 36x = 16
4x = 16
x = 4
