By definition, the power is given by:
 P =  \frac{W}{t}
 By definition, the power is given by:
 Where,
 W: Work done
 t: time
 Clearing the time we have:
 t = \frac{W}{P}
 Substituting values we have:
 t = \frac{1800000}{15000}
 Making the corresponding calculations we have:
 t = 120s
 Answer:

Sam Sounds received a $290 discount loan to purchase a stereo. The loan was offered at 16% for 90 days. Find the interest in dol
garri49 [273]
I = Adt; where p = $290 is the Amount of the loan, d = 16% = 0.16 is the discount rate and t = 90days = 90/365 = 18/73 is the period.

I = 290 x 0.16 x 18/73 = 11.44
Interest = $11.44

Proceed = Amount - Interest = 290 - 11.44 = $278.56

On their first dive, researchers explore a part of the ocean floor that is 60 feet
DENIUS [597]

Answer:

d < -60

Step-by-step explanation:

Let d represent the depth of the researchers' second dive.

Given;

Depth of First dive = -60 ft

It was stated that in their second dive, the researchers explore a deeper depth, That is depth deeper than 60 ft.

Since the depth of 60ft is represented by the integer -60,

Deeper depth would be represented by integers less than -60.

So, d can be represented as;

d < -60

10) 9 people can paint a bridge in 5 hours,
ale4655 [162]

Step-by-step explanation:

The number of people to paint the bridge is inversely proportional to the number of hours it takes.

(If there are more people, it will take less time etc.)

9 people can paint the bridge in 5 hours.

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
