Answer:
The answer is 3
Step-by-step explanation:
B/c 8+2=10 just add one more and 2+1=3
Answer:
We write the generic form equation:
y = A (b) ^ t
We must use two points in the table to find the constants A and b
We have then:
For: t = 1, y = 55
55 = A (b)
For: t = 2, y = 60
60 = A (b) ^ 2
We solve the system of equations:
We divide both equations:
(60 = A (b) ^ 2) / (55 = A (b))
((60) / (55)) = b
b = 1.091
We substitute in any of the equations:
55 = A (b)
55 = A (1,091)
A = (55) / (1,091)
A = 50.41
The equation that models the problem is:
y = 50.41 * (1.09) ^ t
For t = 29 we have:
y = 613.5996987 (> 600)
Answer:
Assuming the trend continues the environment will not last until the population after 24 years.
Answer:
24
Let us take number of $5 bills = x and
number of $10 bills = y.
Give that "number of $10 bills is twice the number of $5 bills".
So, y is twice of x,
We can setup an equation.
y= 2x ............................... equation(1)
Total value of all bills = $125.
We can setup another equation,
5*(number of $5 bills) + 10*(number of $10 bills) =125.
5(x) +10(y) = 125 ................................... equation(2)
Plugging y=2x in equation(2), we get
5(x) +10(2x) = 125 .
5x+20x = 125.
Adding like terms
25x = 125
Dividing both sides by 25.
25x /25 = 125/25
x= 5.
Plugging x=5 in first equation, we get
y= 2(5) = 10.
Therefore, number of number of $5 bills=5 bills and number of $10 bills = 10 bills.
