Answer: 0.000527
Step-by-step explanation:
Given: in standard form.
The standard form are also known as scientific notation.
Scientific notation is a way to write a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.
Since the power of 10 is negative, then it must be smaller than 1.
We can write the given number in decimal form as
Answer:
The time is less than or equal to 1.5 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x -----> the time in hours
The inequality that represent this situation is equal to
Solve for x
Multiply by x both sides
Divide by 70 both sides
Rewrite the inequality
therefore
The time is less than or equal to 1.5 hours
Answer: 70m - 34o
Step-by-step explanation:
to run 9 miles on Tuesday and 12 miles on
Thursday. How many minutes longer will her
run be on Thursday compared to Tuesday?
Answer: 33.33 minutes longer.
Step-by-step explanation :
We need to remember the following formula:
Where "t" is the time, "d" is the distance and "V" is the speed.
We know that she runs approximately 5.4 miles per hour, then:
Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:
Making the conversion from hours to minutes, we get:
Since she plans to run 12 miles on Thursday, her run's time on that day will be:
Making the conversion from hours to minutes, we get:
Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:
