jimmy earns $7.50 per hour. how long will it take him to earn $150? What is the equation to solve this problem?

Answers

Answer:

$150 = $7.50/hour × t

Step-by-step explanation:

To determine how long it will take Jimmy to earn $150 at a rate of $7.50 per hour, you can set up an equation.

Let "t" represent the number of hours it will take Jimmy to earn $150.

The equation for this situation is:

Earnings = Rate × Time

In this case,

Earnings is $150, Rate is $7.50 per hour, and Time is "t" hours.

So, the equation becomes:

$150 = $7.50/hour × t

Now, you need to solve for "t." To do that, you can divide both sides of the equation by $7.50/hour to isolate "t":

t = $150 / ($7.50/hour)

t = 20 hours

So, it will take Jimmy 20 hours to earn $150 at a rate of $7.50 per hour.

Answer:

7.50x = 150

Step-by-step explanation:

7.50x = 150

x = 150/7.50

x = 20 hours

How many batting lineups are there for nine players of a baseball team if the center fielder must bat fourth, the second baseman must bat third and the pitcher last?

Answers

The number of possible batting lineups is 720

Explanation

Total number of players in the team = 9

The center fielder must bat fourth, the second baseman must bat third and the pitcher last. That means, 3 slots in the batting line-up are already assigned to 3 players.

So, the remaining (9 - 3) = 6 players will be assigned to remaining 6 slots.

Thus, the possible number of ways so that 6 players can be assigned to 6 slots will be: $6! = 6*5*4*3*2*1=720$
