there will be 26 blue marbles
Step-by-step explanation:
41-15=26
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
Let's get started!! hahah
The tenths place is the place right after the decimal
When rounding,
This number either stays the same (if the number after it is lower than 5)
or increases by 1 (if the number after it is 5 or greater)
1) 29.516. 5 is in the tenths place look at the number after this.. 1: it is LESS THAN 5 so the answer is 29.5
2) 84.78 7 is in the tenths place look at the number after this.. 8: it is GREATER THAN 5 so the answer is 84.8
3)1017.36 3 is the tenths place look at the number after this.. 6: it is GREATER THAN 5 so the answer is 1017.4
Hope that helps
Given:
Population is 2005 = 35,700
growth rate = 4% = 0.04
To find:
The population in 2030.
Solution:
The general exponential growth model is
where, a is initial value, r is growth rate and t is time in years.
Let the initial year is 2005. So, number of years between 2005 to 2030 is
Putting a=35,700, r=0.04 and t=25 in the above model.
Approximate the value to the nearest whole number.
Therefore, population of the district will be about 95,170.
