Answer:
2.4 x 10-₃
Step-by-step explanation:
the numbers with NO zeros should be first and the first number should be turned to a whole so like "2.4". Since there are 3 zeros (including the zero in the whole number place) you would write the 3 as the number in the right corner. And there is a minus sign beside the 3 because the Zeros are first. :)

Answer: the bus would be used 30 times for the monthly costs to be the same.
Step-by-step explanation:
Let x represent the number of times in a month for which the bus must be used so the total monthly cost is the same with the book as it is without it.
The bus fare without a coupon book is $1.50. This means that the total monthly cost of using the bus for x times without a coupon book is 1.5x
A coupon book cost $30.00 and with the coupon book, the fare is reduced $0.50. This means that the total monthly cost of using the bus for x times with a coupon book is
0.5x + 30
For the monthly costs to be the same,
1.5x = 0.5x + 30
1.5x - 0.5x = 30
x = 30
Answer:
the answer is 2.4 million
Step-by-step explanation:
In order to find the rate of change, you first must find the amount that the population grew in the time period:
314-302 = 12
Now you need to calculate the number of years:
2012-2007 = 5
Lastly, divide the amount of change by the number of years:
12/5 = 2.4
The population grew by 2.4 million people per year. Hope this helps! :)
Ahh, the ol' trick word problems.
Okay so lets break this down.
So we have 7,000 square feet of work that must be done. We can lose the square feet part as it will only interfere with solving the problem.
So lets say we have 7,000 amount of work that needs to be done.
We know that our company can get 35 work done in one hour. Our company also works 10 hours per day so we can say we get 350 work done per day.
We need to figure out how much of the work we got done in four days so we can multiply it by 4 and get 1400 work in four days.
1400/7000 work has been complete. Lets simplify this.
14/70 work has been completed.
Now we need to find the percent using our good friend ratios.
14/70 = x/100
Then we use cross multiplication to solve and we get 20/100.
We have 20% of the work done.
Pro Tip: In real life, you can assume that when you are at 20% work done that it wont actually be 20% because your boss will want you to be done within 12 days. In real life, you would have 60% of it done and on to the next project!
