If the scale on a map is 1/4 in. = 50 miles, how many miles do 3 3/8 inches represent?
Korvikt [17]
Hey there Fish Girl!

So, if \left[\begin{array}{ccc}1/4 \end{array}\right] equals 50 miles, then we would do this multiplied by . . . . 

So, if we would want to go to 3 whole, we would then have to go to the number 3 of course. So then, we do \left[\begin{array}{ccc}4*3=12\end{array}\right] and then from this, we would have to multiply this my 50.

The reason to why we would have to do this is because 1/4 of a mile is 50, so then, sense we are trying to get to the number 3, then, from doing this,we would determine a figure out how many miles this would conclude to be.

\left[\begin{array}{ccc}12*50\end{array}\right]   =\left[\begin{array}{ccc}\boxed{\boxed{600}} \ so \ far!\end{array}\right]

So, now, we have covered 3 as a whole, then we would have to see how 3/8 and also 1/4 can relate to each other.

So, in this case,\boxed{\boxed{ \frac{3}{8} \ would \ be \ almost \ \boxed{half} \\ \ because \ it \ is \ almost  \frac{4}{8} }}

So, most likely, it would stay the same as it is, 1/4 because this is almost half to.

SO ALL WE WOULD NEED TO DO NOW IS TO ADD . . . . . 

\left[\begin{array}{ccc}\left[\begin{array}{ccc}\boxed{\boxed{600+50 \ or  \frac{1}{4}=650}} \end{array}\right]\end{array}\right]

YOUR CORRECT AND FINAL ANSWER TO THIS QUESTION WOULD BE. . . . 

\left[\begin{array}{ccc}650 \ miles\end{array}\right]

Hope this helps you fish Girl! :)

Seven times a number is equal to 9 more than 4 times the number. find the number
Yanka [14]
Represent 'a number' by x
7 times x equals 9 more than 4 times x
7 times x=9+4 times x
7x=9+4x
subtract 4x from both sides
3x=9
divide 3
x=3

the number is 3

Every evening, two weather stations issue weather forecast for the next day. The weather forecasts are independent. On average,
EleoNora [17]

Answer:

The probability is 0.6923

Step-by-step explanation:

Let's call R the event that the next day rains, S the event that the next day has sunny weather, R2 the event that the station 2 predicts rain and S1 the event that station 1 predict sunny weather.

The probability that the next day has sunny weather given that station 1 predicts sunny weather for the next day and station 2 predicts rain is calculated as:

P(S/S1∩R2) = P(S∩S1∩R2)/P(S1∩R2)

Where P(S1∩R2) = P(R∩S1∩R2) + P(S∩S1∩R2)

So, the probability P(R∩S1∩R2) that the next day rains, Station 1 predicts sunny weather and Station 2 predicts Rain is calculate as:

P(R∩S1∩R2) = 0.5 * 0.1 * 0.8 = 0.04

Because 0.5 is the probability that the next day rains, 0.1 is the probability that station 1 predicts sunny weather given that it is going to rain and 0.8 is the probability that station 2 predicts rain given that it is going to rain.

At the same way, the probability P(S∩S1∩R2) that the next day has sunny weather, Station 1 predicts sunny weather and Station 2 predicts Rain is calculate as:

P(S∩S1∩R2) = 0.5 * 0.9 * 0.2 = 0.09

Then, the probability P(S1∩R2) that station 1 predicts sunny weather for the next day, whereas station 2 predicts rain is:

P(S1∩R2) = 0.04 + 0.09 = 0.13

Finally, P(S/S1∩R2) is:

P(S/S1∩R2) = 0.09/0.13 = 0.6923
