Answer:

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ 4}

Step-by-step explanation:

The given expresion is;

{7}^{ - 2}  \cdot {7}^{6}

We apply the product rule of indices;

{a}^{m}   \cdot \:  {a}^{n}  =  {a}^{m + n}

We apply this property to our expression to get:

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ - 2 + 6}

Simplify the exponent on the right;

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ 4}

We can't see the options, but I hope this helps!

Two commuters leave the same city at the same time but travel in opposite directions. One car is traveling at an average speed o
r-ruslan [8.4K]

Answer:

5 hours

Step-by-step explanation:

The formula to relate speed, distance and time is:

D = V * t

Where D is the distance, V is the speed and t is the time.

As they are in opposite directions, we need to sum the speed.

So the total speed is:

V = 63 + 59 = 122 mph

So using this value and V and using D = 610, we have:

610 = 122 * t

t = 610 / 122 = 5 hours

So they will be 610 miles apart after 5 hours.

Zarrin [17]

22% liked neither.

Step-by-step explanation:

Given,

64% liked pop music.

52% liked rap music.

38% liked both type of music.

To find out the percentage of those liked neither.

Now,

Let, total number of student = 100

Number of students liked pop = 64

Number of students liked rap = 52

Number of students liked both = 38

So,

Number of students who liked only pop = 64-38 = 26

Number of students who liked only rap = 52-38 = 14

Hence,

Number of students who liked neither = 100 - (26+14+38) = 22

22% liked neither.
