Answer:
Firstly we calculate the number of hours of both months.
This year is not a Leap year. So, the number of days of February is 28
and the number of days of March is 31
So, Number of hours February has 28 × 24 = 672 hours
and, Number of hours March has 31 × 24 = 744 hours
The bar graph is the best visual representation when we have categorical data. It is drawn by using a rectangular bar where the length of the bar represents height or frequency.
Answer is 3000.
Explanation;
The given number is 3489.
Before rounding off the given number we should know the place values of the digits. Here,
ones - 9
tens - 8
hundreds - 4
thousands - 3
In this problem, we have to round off the given number to nearest thousand.
Before that, we should look at the digit at the hundreds place.
If that digit is equal or more than 5, we should add 1 to the digit in thousands place unless keep the digit same as it.
Here, 4 is the digit which is before thousands place. 4 is less than 5. Hence, we can keep the digit in thousands place as unchanged.
Hence, rounded off number to nearest thousand is 3000.
Solution:
Making list makes your work easy.
Suppose monthly income of a person is 10,500 $. Amount spent on housing finances is $45,00, paying car loan per month is $ 200, tuition charges for their son and daughter in different activities that they do is $ 200.And once in a month they go for excursion .The amount spent on excursion is $ 250. Find the total amount spent by that person in a month.
Solution:
So, we will make the list of the amount spent on various activities by that person , then we can find the total amount spent in month by that person.
1. Amount spent on housing finances= $ 4500
Amount spent on car loan per month = $ 200
Amount spent on tuition charges for their son and daughter in different activities=$ 200
Amount spent on excursion =$ 250
Total money spent by that person in different activities=$ 4500 +$ 200+$ 200+$ 250= $ 5,150
So, we have made list here to solve this problem, which made our work easier.
Suppose the housing expenses is $ 4500 , which includes different items that the family buys for their household expenses, for that we can make list also.
