Answer:

A) 6.6248 x 10^-3

Step-by-step explanation:

You first do the exponents of the 10s

(7.28 x 10^-2) = (7.28 x 0.01) , (9.1 x 10^-3) = (9.1 x 0.01)

Then multiply the parentheses

(7.28 x 0.01) = 0.0728 , (9.1 x 0.01) = 0.091

Then multiply both products together

0.0728 x 0.091

= 0.0066248

In order to simplify this into an equation you can count the amount of decimal placements you would need to move make a whole number, then the amount of placements is your exponent, in this case it is 3. Then since they're all 0s you use the base of 10 and since the value is shrinking you sue a negative exponent

0.006248-----> 6.6248 x 106-3

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile
Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where  d represents the distance, that the car travels at this speed in t  at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.
