Since 45 minutes is 75% of an hour, you need to convert into a decimal and add 2. Which gives you 2.75. Then you have to divide 8,580 by 2.75 and you get a final answer of 3120 words. Hope this helps!
Let the hours when they equalize=h, then we have:
12.25 + .13h=13 - .09h
.13h + .09h=13 - 12.25
.22h=.75 divide both sides by .22
h=.75/.22
h=3 9/22, hours, when they will equalize.

given f(x) in factored form, equate to zero for x-intercepts
(x - 8)(x - 4) = 0, hence
x = 4, x = 8 ← x- intercepts
The vertex lies on the axis of symmetry which is situated at the midpoint of the x- intercepts
x- coordinate of vertex = 
= 6
f(6) = (6 - 8 )(6 - 4 ) = -2 × 2 = - 4 ← y-coordinate
vertex = (6, - 4 ) → B
Answer:
95 is the answer I took the test
1 is 100 degrees
2 is 72 degrees
3 is 9 degrees
4 is 125 degrees
5 is 155 degrees
6 is 91 degrees
7 is x=28 degrees
8 is x=125 degrees
9 is x=35
10. angle 2 is 86 degrees (vertical angles)
11. angle 3 s 94 degrees (supplementary to angle 2)
12. angle 4 is 86 degrees (<4 and <2 are alt. interior angles and are congruent)
13. angle 6 is 86 degrees (<6 and <4 are vertical angles)
