<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>
Let X = number of Giraffes
Number of elephants = 3X - 4
Because it was stated that there are more than 23 elephants, the number should not fall below 23.
The algebraic expression would be:
3X - 4 = 23
To get X; Transfer -4 to the other side, changing its sign to positive.
3X = 23 + 4
3X = 27
To get X; Divide both sides by 3
X = 27 / 3
X = 9
Since X represents the number of giraffes, then, there are 9 giraffes in the zoo.
To Check: Substitute X with 9 in the algebraic expression.
3X - 4 = 23
3(9) - 4 = 23
27 - 4 = 23
23 = 23 EQUAL
Half angle K is 30 and the center is 90 so that half angle J is 60 and angle H is equal to angle K so half of H is 30 so that half of G is 60
m<1 =60

The volume of the ethanol inside the tube can be obtained by dividing the mass of ethanol by the density. The volume is equal to 15.03 ml or 15.03 cm3. The volume of the tube is equal to pi d^2/4 * h where h is 15 cm. From this formula, the diameter is equal to 1.13 cm.
