This is the concept of application of the Pythagorean theorem. The resultant speed of the motorboat which is crossing the river that has a northward current of 5 m/s at a speed of 8 m/s will be given by:
c^2=a^2+b^2
c^2=8^2+5^2
c^2=64+25
c^2=89
c=sqrt89
c=9.4 m/s

Four of the 7 students got a sticker, so you need to turn that into a percent. To do that, divide 7 by 4, which gives you .57. That means that 57% of students got a sticker.

you are given the measure of angle 4. You also know the following angles are supplementary: Angles 1 and 2, angles 2 and 3, angl
Harrizon [31]
If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which  will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)

Solve using substitution method. 3×-4y=18 and 2x + y = 1
Shalnov [3]
3x - 4y = 18 ⇒ 3x -  4y = 18
2x +  y =   1 ⇒ 8x + 4y =   4
                              11x = 22
                               11     11
                                  x = 2
                          2x + y = 1
                       2(2) + y = 1
                           4 + y = 1
                         - 4        - 4
                                 y = -3
                            (x, y) = (2, 3)
