Vedavit walks his dog the same distance each day. After 5 days, he has walked his dog 1 mile. How many feet does he walk his dog
posledela

Answer:

1056 ft

Step-by-step explanation:

''Vedavit walks his dog the same distance each day.''

After 5 days,he has walked his dog 1 mile.''

First we are going to convert the total distance (1 mi) to feet.

The relation is :

1mi=5280 ft

After 5 days, he has walked his dog 5280 ft.

The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)

\frac{5280ft}{5 days} =1056\frac{ft}{day}

Finally, he has walked his dog 1056 ft each day

Please help i need this done asap
ki77a [65]

Answer:

A

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} = a^{(m+n)}  , a^{-m} = \frac{1}{a^{m} }  , a^{0} = 1

(14x³y^{-4} )(4x^{-5}y^{4} )

= 14 × 4 × x³ × x^{-5} × y^{-4} × y^{4}

= 56 × x^{(3-5)} × y^{(-4+4)}

= 56 × x^{-2} × y^{0}

= 56 × \frac{1}{x^2} × 1

= \frac{56}{x^2} → A
