Answer:
175 cm
7 years
Step-by-step explanation:
Here is the complete question
When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard.
He measured it once a year and found that it grew by 26 centimeters each year. 4.5 years after he moved into the house, the tree was 292 centimeters tall.
1. How tall was the tree when Vlad moved into the house?
2. How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?
The formula for calculating future value:
FV = P + (r x n)
FV = Future height of the tree
P = Present height of the tree
R = growth rate
N = number of years
292 = p + (26 x 4.5)
292 = p + 117
p = 292 - 117
p = 175 cm
b. 357 = 175 + (26 x n)
375 - 175 = 26n
182 = 26n
n = 182 / 26 = 7 years
60 because area of a rectangle is l*b*w. So 6*2*5 will equal 60
Answer:
Step-by-step explanation:
Let x is the total population of the world.
Therefore, by the condition given the population of North America is 
Again it is given that 
fraction of the world's population lives in the United States of America.
So, 
is the population of USA.
Therefore, the fraction of the population of North America that is the population of USA will be 
(Answer)
You can conclude that x is less than y, because a smaller number - a bigger number is equal to a negative number. :)
