Answer:

  26 2/3 mph

Step-by-step explanation:

  time = distance/speed

  speed = distance/time

Use the first of these relations to find Aidan's time getting to school:

  time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h

Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...

  speed = 16 mi/(0.6 h) = 26 2/3 mi/h

slavikrds [6]

Answer:

F(t) = 10 + 5(t)

Step-by-step explanation:

The complete question is as follows;

Anumeha is mowing lawns for a summer job. for every mowing job, she charges an initial fee of \$10$10dollar sign, 10 plus a constant fee for each hour of work. her fee for a 555-hour job, for instance, is \$35$35dollar sign, 35. let f(t)f(t)f, left parenthesis, t, right parenthesis denote anumeha's fee for a single job fff (measured in dollars) as a function of the number of hours ttt it took her to complete it. write the function's formula.

Solution

We are interested in writing the function F(t) formula for the fee charged by Anumeha per job.

Now, the key to writing this function is knowing exactly the constant fee she charges on the job.

We were told that she got $35 for a 5 hour job.

Thus, the constant amount charged is as follows;

Since it’s $10 as initial fee and the constant fee is per hour;

35 = 10 + 5(x)

where x is the constant fee per hour

35 = 10 + 5x

5x = 35-10

5x = 25

x = 25/5

x = $5

This mess that she charges a constant fee of $5 per hour

So we can write the equation now.

F(t) = 10 + 5(t)

where t represents the number of hours she spent on the job

Find the missing value for log4 9- log4 11= log 4 [ ]
Alexandra [31]

Answer:

Step-by-step explanation:

Hi there,

To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:

log_b\alpha -log_b\beta =log_b[\frac{\alpha }{\beta } ]

In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing <u><em>argument</em></u> (the number inside of the log, what we are asked to solve for):

log_49-log_411=log_4[\frac{9}{11} ]\\   hence the missing argument is 9/11

At this point, there is no easier say to simplify, unless you wish to approximate  9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.

If you liked this solution, leave a Thanks or give a rating!

thanks,
