<span>It is estimated that the city of Houston, Texas, will double in size every 35 years:
</span>P=Po(2)^(t/35)
<span>If the population is currently 2.4 million people:
Po=2.4 millions
</span><span>How many people will there be in 20 years?
t=20 years, P=?
P=(2.4 millions)(2)^(t/35)
P=(2.4 millions)(2)^(20/35)
P=(2.4 millions)(2)^(0.571428571)
P=(2.4 millions)(1.485994289)
P=3.566386294 millions
P=3.6 millions
Answer: There will be 3.6 million people in 20 years.</span>
Answer:
There are 42 red colour socks and 44 green color socks
Step-by-step explanation:
Let there are r red socks and g green socks.
ATQ,
He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.
4g-3r=50 ....(1)
Half the number of green socks plus one-third of the number of red socks is 36.
Multiply equation (1) by 2 and equation (2) by 3.
8g-6r = 100 ....(3)
9g +6r = 648 ....(4)
Add equation (3) and (4)
8g-6r + 9g +6r = 100+648
17g = 748
g = 44
Put the value of g in equation (1).
4(44)-3r=50
176-3r = 50
176-50 = 3r
r = 42
Hence, there are 42 red colour socks and 44 green color socks.
