What is −300 ÷ (−13) = and how would i write out this problem to solve?
never [62]

Answer:

  23 1/13

Step-by-step explanation:

You have done a pretty good job of writing the problem, negative 300 divided by negative thirteen. It can be translated directly to your favorite calculator (see attachment) for a solution.

If you want to perform the division by hand, the particular method of writing the problem depends on the method of division you want to use. (Several styles are taught these days). Numerous web sites and videos explain <em>long division</em> in all its detail. The second attachment shows an example where a decimal fraction result is obtained. The decimal fraction is an infinite repeating decimal with a 6-digit repeat.

For starters, you would generally convert both numbers to positive numbers, since the result of 300/13 is the same as the result of -300/-13 and positive numbers are easier to deal with.

___

<em>Comment on symbols</em>

(The symbol ÷ generally means the same thing as the symbol /. Both mean "divided by". In some cases, the symbol ÷ is given the meaning "everything to the left of it divided by everything to the right of it." This is often the case when it is used as part of a compound fraction: 3/5÷4/3, for example. The preferred representation of such a division is (3/5)/(4/3), with parentheses clearly identifying numerators and denominators.)

Monica has a goal to complete a triathlon. The race consists of a 2.4-mile swim, a 112-mile bike ride, and a 26.2-mile run. In t
klasskru [66]

Taking into account the definition of speed, Monica will complete the triathlon in 12.62 hours.

<h3>Definition of speed</h3>

Speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:

speed= distance traveled÷ time

<h3>Time to complete the triathlon</h3>

In this case, you know

  • Swim:
  1. speed= 1.8 mph
  2. distance traveled= 2.4 miles
  • Ride a bike
  1. speed= 19.2 mph
  2. distance traveled= 112 miles
  • Run:
  1. speed= 4.8 mph
  2. distance traveled= 26.2 miles

Replacing these values ​​in the speed definition:

  • Swim: 1.8 mph= 2.4 miles÷ time to swim
  • Ride a bike: 19.2 mph= 112 miles÷ time to ride a bike
  • Run: 4.8 mph= 26.2 miles÷ time to run

Solving:

<u><em>Swim: </em></u>1.8 mph×time to swim= 2.4 miles

time to swim= 2.4 miles÷ 1.8 mph

time to swim= 1.33 h

<u><em>Ride a bike:</em></u> 19.2 mph× time to ride a bike = 112 miles

time to ride a bike= 112 miles÷ 19.2 mph

time to ride a bike=5.83 h

<u><em>Run: </em></u>4.8 mph× time to run= 26.2 miles

time tu run= 26.2 miles÷ 4.8 mph

time to run= 5.46 h

The time to complete the triathlon is the sum of each of the stages:

Total time= time to swim + time to ride a bike + time to run

Total time= 1.33 h + 5.83 h + 5.46 h

<u><em>Total time= 12.62 h</em></u>

In summary, Monica will complete the triathlon in 12.62 hours.
