4.29 + 97.2 + 0.687 = 102.177
In adding decimal numbers, make sure that the decimal points are aligned. Since each number has different counts of numbers after the decimal point, use 0 to pad the missing places.
4.290
97.200
<u> 0.687
</u> 102.177
The count of numbers after the decimal point is the same count of number of the decimal who has the greatest count of number after the decimal point.
4.29 only has 2 counts of places after the decimal point
97.2 only has 1 count of place after the decimal point
0.687 has 3 counts of places after the decimal point.
The sum of the decimals must also have 3 counts of places after the decimal point.
Answer:
$36
Step-by-step explanation:
Use the simple interest formula, I = prt
Plug in the interest rate, original amount of money, and number of years:
I = prt
I = (150)(0.08)(3)
I = 36
So, $36 in interest would be made
Answer: 121871
Step-by-step explanation:
Current population = 98000
Rate of increase = 3.7% / year
Total time = 2020 - 2014 = 6 years
Population in 2020 = 98000 * (1+ (3.7/100))^6
= 98000 * (1.037)^6 = 98000 * 1.243576 = 121870.505
Rounding off to nearest whole number we get the population = 121871
15.
if he ordered the same amount each month (x) and it is a whole number,
then
12*x=6150, and
x =6150/12 should be a whole number
x=512.5
so 512.5 is not a whole number and the produce company does not agree
16.
16410/138≈118.91
because it not a whole number, she sells pieces for different prices
