Answer:
Speed = 10.42 m/secs
Step-by-step explanation:
We have been given with:-
Distance = 100m
Time taken = 9 secs
1) First, we need to convert the mixed number 9 to an improper fraction.
<u>Method to convert a mixed number to an improper fraction</u>
<u></u>
Applying the above formula, we get
9 =
=
=
2) Now we need to convert into a decimal by dividing 48 by 5.
We get time taken as 9.6 secs
3) We need to find the speed using the below formula:-
Speed =
Plugging the values of Distance and Time taken into the formula, we get
Speed =
= 10.416 m/secs
4) Upon rounding it to the nearest hundredth, we get
Speed = 10.42 m/secs
18 feet:7 yards : : 18 feet: 21 feet
18: 21 : : 6: 7
Simplified as a fraction it would be 6/7

Answer:
she would be a investor
Step-by-step explanation:
Hey there! I'd be delighted to help you out!
First, let's write down our expression!
When we look at this expression, we see that all of the numbers are <u>terms, </u>or numbers that are added. We have four terms in this equation, which are:
Now, to simplify, we want to combine like terms. Like terms are numbers that have the same variable (or no variable) and are raised to the same power. 1 and 5 are like terms because they both have no variable and they are both raised to the power of 1 (any number that is itself is raised to this power). 4x and 12x are like terms because they both have an x and a power of 1. 4y and 5x are not like terms because they have different variables. 4x³ and 2x² are not like terms because they are raised to different powers.
Now, we see that with our numbers, x² and -2x² are like terms, and -x and 8x are also like terms. We can combine accordingly.
Now we combine to get our simplified expression!
I hope that this helps! Have a wonderful day!
