3 1/2 hours because Rodriquez graded one hour of papers and if his assistant grades the class papers in 4 1/2 hours, it should only take him 3 1/2 hours since Rodriquez helped with an hour of it

A man drove 14 mi directly east from his home, made a left turn at an intersection, and then traveled 5 mi north to his place of
Stels [109]

Answer:

14.9 miles

Step-by-step explanation:

If the road was created, the 3 different roads would form a right triangle where the new road would be the hypotenuse and the other 2 roads would be the legs.

We can use the pythagorean theorem to find the length of the hypotenuse, or the new road:

a² + b² = c²

14² + 5² = c²

221 = c²

14.9 = c

= 14.9 miles

Overtime is over 40 so subtract 40 from 54 and get
54-40=14
14 hours hovertime
so multipliy usuall pay by 40 (since worked 40 normal hours) then add to overtime pay by 14 hours so


(13.5 times 40)+(13.5 times 1.5 times 14)=

Select the representation that does not change the location of the given point. (4, 110°)
miss Akunina [59]

Answer:

(4,470°)

Step-by-step explanation:

The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.

The only point among the given options that is coterminal with (4, 110°) is (4, 470)°

The two points have the same magnitude and 470°-360°=110°.

Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.

The correct choice is (4,470°)
