Answer:

406.153846 or about 406 feet per minute

Step-by-step explanation:

Start by converting the 13 minutes per mile to feet per minute by turning the mile into 5,280 feet. So you run 5,280 feet in 13 minutes. Then you divide 5,280 by 13 so you get the amount of feet  per minute, hence about 406 feet per minute.

I didn't know if you needed an exact answer or to round so I gave you both :)

Simplify. Rewrite the expression in the form 5^n<br>(5^3)^2=<br>​
Temka [501]

Answer:

5^12

Step-by-step explanation:

index notation rules states that when there is a power inside AND outside the brackets, they shall multiply together. hence, we will multiply 3 and 2 so we will get 6 and thus the answer will be 5^6. Sike, that's not the answer, we forgot to multiply 5 with that power too... so we will get 25^6 because same power (outside brackey) will affect everything inside...

now after we got 25^6, we need to simplify it to get 5^n ....

so as we know 5^2 is 25, we can do this,

(5^2)^6 so we will multiply the powers to get

5^12 which is your answer :)

pls mark this as brainliestttt

(Urgent plz help :”) )Find the value of w.
GarryVolchara [31]

Answer:

The value of w is 7.

Step-by-step explanation:

According to Pythagoras theorem,

Hypotenuse²=Perpendicular²+Base²

H²=P²+B²

Here,

Hypotenuse given=7√2

w=y

Perpendicular=Base=x

(7√2)²=x²+x²

49*2=2x²

(49*2)/2=x²

49=x²

√49=x

7=x

Perpendicular=x=7
