Answer:
s= -2
Step-by-step explanation:
The ground, the building, and the ladder form a right triangle, in which
the leaning ladder is the hypotenuse.
For the angle between the ladder and the ground, the 4-ft along the ground
is the side adjacent to the angle, and the 7-ft ladder is the hypotenuse.
(adjacent side) / (hypotenuse) = cosine of the angle.
Cosine(a) = 4/7 = 0.57143... (rounded)
Angle 'a' = <em>55.15 degrees</em> (rounded)
Let the second train catch up after x hours
<span>Distance = speed X time </span>
<span>135x = 105 ( 2 + x) </span>
<span>135x = 210 + 105x </span>
<span>30x = 210 </span>
<span>x = 7 hours (after 2nd train has started ) </span>
<span>ANSWER 7 X 135 = 945 miles from the starting point </span>
<span>CHECK </span>
<span>7 X 135 = 945 miles </span>
<span>9 X 105 = 945 miles</span>
Step-by-step explanation:
Step one:
we are given the equation for Addy And Rachel's earning as
-------------1
Step two:
Context creation
Say john earns $0.9 per paper he delivers, estimate how much he would earn to deliver 10 papers
let the amount earn be y and the number of papers delivered be x
the equation is
y=0.9x
for x=10
y=0.9(10)
y=$9
<u>We can see that John's unit rate is more than Addy's unit rate</u>
