A fisherman can row upstream at 5mph and downstream at 10mph he started rowing upstream until he got tired and then rowed downst

AlekseyPX

We have been given that the upstream speed is $5 mph$ and the down stream speed is $10mph$ .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is $s = \frac{d}{t}$

Hence, $t= \frac{d}{s}$

Time upstream + time downstream = 6

$\frac{x}{5} +\frac{x}{10} =6$

lcm = 10

$\frac{2x+x}{10} =6$

=> $\frac{3x}{10} =6$

Cross multiplying, $3x= 60$

x = 20 miles .. Answer.

Find the mean absolute deviation of the set of data 3,8,10,12,15

inn [45]

Answer:

3.28

Step-by-step explanation:

find the mean of all the numbers

3 + 8 + 10 + 12 + 15 = 48

48/5=9.6

so the mean of all the numbers is 9.6

now subtract 9.6 from all the numbers

|3 - 9.6| = 6.6

|8 - 9.6| = 1.6

|10 - 9.6| = .4

|12 - 9.6| = 2.4

|15 - 9.6| = 5.4

Find the mean/average of the new values

6.6 + 1.6 + .4 + 2.4 + 5.4 = 16.4

16.4/5 = 3.28

The product of two consecutive positive integer is 1,332. Explain how you can write and solve a quadratic equation to find the v

Igoryamba

<u>Answer:</u>

<u>Step-by-step explanation:</u>

Product of two consecutive integers: assuming $x$ to be the first positive integer so the next consecutive integer will be $x+1$ .

So we get the equation:

$x(x+1)=1332$

Now solving it to get the value of the larger integer (x+1):

$x ^ 2 + x = 1332$

$x ^ 2 + x - 1 3 3 2 = 0$

$(x+37)(x-36)=0$

(Ignoring the negative value of x)

$x=36$

Therefore, the larger integer will be $x+1=36+1=$ 37.

A deli has a special one day event to celebrate its anniversary. On the day of the event,every eighth customer receives a free d

stellarik [79]

We have to find the customers who receive a free drink and a free sandwich separately and then find the common between the two sets of customers

Since every 8th customer receives a free drink, these customers would be 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192 and 200

Since every 12th customer receives a free sandwich, these customer would be: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180 and 192

So the common customers among the two sets are customers 24, 48, 72, 96, 120, 144, 168 and 192

So the number of common customers are 8 in number

Conclusion: 8 customers will received both a free drink and a free sandwich
