Answer:

0.44

Step-by-step explanation:

This is a right angled triangle, so it yields:

                                             \cos \angle V = \frac{adjacent}{hypotenuse}

The value of <em>adjacent </em>is 39.

We will use the Pythagorean rule to obtain the length of hypotenuse:

                                         hypotenuse^2 = 39^2 + 80^2\\hypotenuse^2 = 1521 + 6400\\hypotenuse^2 = 7921\\hypotenuse = \sqrt{7921}\\hypotenuse = 89

Now we can insert that into \cos \angle V:

\cos \angle V = \frac{39}{89} =0.44

Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of
vesna_86 [32]

Answer:

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

\dfrac{\$450}{30}=\$15.

Her payment has now been increased by 20%, so her hourly payment becomes

\$15\cdot 1.2=\$18.

If she worked h hours, then she earned \$18h. If her new payment is p, then

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h.
