The Required ratio between the speed of the boat and speed of the water current is 8:3.

<h3>What is ratio?</h3>

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six.

Given:

Upstream time= 8 hr 48 = 8 4/5 hour

Downstream time= 4 hour

Let the man's rate upstream be x kmph and that downstream be y kmph.

Then,

distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.

x* 8 hr 48 min = y* 4 hours

x* 8 4/5= 4y

y= 11/5 x

Now,

Required ratio

(y+x)/2:(y-x)/2

= (16x/5 * 1/2): ( 6x/5 *1/2)

=8/5:3/5

=8:3

Hence, the required ratio is 8:3.

Please help!! Im confused

Answer:

The answer is that you tutored for 4 hours.

Step-by-step explanation:

There are 6 total squares, so then you must divide 12 by the number of squares (6), to find the value of one square. Then, you would find that one square equals 2 hours, and since you have 2 squares that means that you tutored for 4 hours.

Answer:

∠1 = 142°

<u>reason:</u> angles 1 and 2 are supplementary so they equal 180. 180-38 is 142

∠3 = 38°

<u>reason:</u> angles 2 and 3 are adjacent angles because they are diagonal from each other so they will equal the same measure.

∠4 = 142°

<u>reason:</u> since angle 4 is adjacent to angle 1 and is supplementary to angle 3, it has to be 142

∠5 = 38°

<u>reason:</u> since it is a transversal that means both of the intersections are the same measurements. so angle 5 is 38 since it matches up with angle 2

∠6 = 142°

<u>reason:</u> for the same reason as angle 5. angle 6 matches up with angle 1 so it has to equal 142.

∠8 = 142°

<u>reason:</u> since angle 8 is adjacent to angle 6 it has to equal 142. angle 8 is also a transverse angle to angle 4. and since angle 4 also equals 142, 8 has to also

Step-by-step explanation:

hope this helped you :)
