Answer: 4^15</h3>
Explanation:
The rule used is
a^b*a^c = a^(b+c)
Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.
Using the rule, we get
a^b*a^c = a^(b+c)
4^5*4^10 = 4^(5+10)
4^5*4^10 = 4^15
You would need to add 0.25 from t to get the number of hours ( this would be the total number of hours she has raced) and then multiply that by her speed.
The equation would be d = 35(t+0.25)
Answer:
1/5
Step-by-step explanation:
Hi there!
To find the answer, use inverse operations to solve.
Multiply 7/15 by 3/7 to isolate the unknown number.
7/15 * 3/7 is equal to 0.2, which can be simplified into fraction form as 1/5.
I hope this helps!
