Simple. 1.5 as a fraction is 1 & 1/2. If you know how to make fractions decimals, you're set.
Answer:469 million
Step-by-step explanation:
Given
The population of a country at t=1900 is 420 million
and P'(t) is a constant therefore P(t) is a linear function of time
assuming P(t)=7t +c
at t=0 i.e. 1900 at starting Point P(t)=420 million
i.e.
Thus 
Thus at 1907 Population is 469 million
P'(t)=7 indicates that growth rate of Population is constant equals to 7 billion
Answer:
Total height lowered = 75m
No of times balloon lowered = 5
Height lowered in each lowering = Total height lowered / No of times balloon lowered
= 75 / 5
= 15 m
The number indicated that each time balloon is lowered by 15 m
Standard calculation for Perimeter is 2L+2W=P or 2(L+W)=P
As we have the totals for the perimeter at 32m and know the lenght is 6m longer than width we can build an equation to find W.
2(L+W)=Perimeter
2(x+x+6)=32
2(2x+6)=32
2x+6=32/2
2x+6=16
2x=16-6
2x=10
x=10/2
x=5
Now we have the width of 5m. As length is 6m longer than width means we add 6m to 5m to determine length
L=W+6
L=5+6
L=11
To determine if your calculations are correct place your L and W answers into original eqution to determine perimeter
2(11+5)=32
2(16)=32
32=32
Yes, it is found correct. Now to find the Area using the standard formula for Area. Area=L*W or A=LW
A=(11)(5)
A=55
Area = 55sq m
Answer:
there are multiple 0's in the same area, and multiple 2's.
