Answer:
The temperature decreased by 9 °F in <u>6 days.</u>
Step-by-step explanation:
Let the number of days it takes for the temperature to decrease by 9 °F be
.
Given:
Average daily temperature decreases by
°F.
Decrease of temperature in 1 day =
= 1.5 °F.
∴ Decrease in temperature in x days is
.
Now, as per question, decrease in temperature in 'x' days is 9 °F.
Therefore, 


Therefore, the temperature decreased by 9 °F in 6 days.
Yep! 7x2=14-15= -1 // answer is a
The product of two positive fractions are also less than one because you are multiplying a number which is already less than 1.
For example.
1/ 2 = is 50% of a whole.
When you multiply 1/2 by 1/2 you do not get the 100% of the whole because you are only getting 50% of the 50% of the whole, which in turn is equivalent to 25% of the whole.
1/2 * 1/2 = 1/4 of the whole.
The only time you can get a result of 1 and above where two fractions are less than 1 is when you perform addition of these fractions.
1/2 + 1/2 = 1 - ALL CREDITS GO TO @TASKMASTERS!
