Multiplying a negative number and another negative number makes the product positive.
So (-2.1)*(-1.4) = 2.94
Answer:
The radius of the circle with the circumfrence we need to find is 15+3=18.
18*2pi=113.04
Answer:
Step-by-step explanation:
a) We would use the formula for exponential growth model which is expressed as
y = b(1 + r)^t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 5655
r = 1.4% = 1.4/100 = 0.014
Therefore, the equation would be
y = 5655(1 + 0.014)^t
y = 5655(1.014)^t
b) in 2022, t = 2022 - 2010 = 12 years
y = 5655(1.014)^12
y = 6682
21/7=3 With $21 you can buy 3 tickets at $7 a piece.
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
