Answer:
$13.40
Step-by-step explanation:
First you subtract the lax from the total cost of the CDs then you divided that total by the number of CDs which is 6.
84.60 - 4.20 = 80.40
![\sqrt[6]{80.40}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B80.40%7D)
= $13.40
Bisector must pass through the mid-point, so we have to find out that mid-point of the segment:
mid point = x₁+x₂ / 2 , y₁+y₂/2
= 1 + 5 / 2 , 1 + 7 / 2
= 6/2 , 8/2
= (3, 4)
Slope of given segment = m = y₂-y₁ / x₂- x₁
m = 7-1 / 5-1
m = 6/4
m = 3/2
Now, segment which is perpendicular, will have the opposite & reciprocal slope, So, it would be: -2/3
We know, y - y₁ = m(x - x₁)
y - 4 = -2/3(x - 3)
y - 4 = -2/3x + 2
y = -2/3x + 6
In short, Your Final Answer would be: y = -2/3x + 6

(55 km/h) * (1 mi)/(1.609344 km) ≈ 34.2 mi/h
_____
You can do units conversions pretty easily by multiplying by a conversion factor whose value is 1. That is, since
.. 1 mi = 1.609344 km
dividing by the left side we have
.. (1 mi)/(1.609344 km) = 1
This factor has the convenience that it will cancel km and give mi when multiplied by some number off km. That is what we did above. (The "per hour" just went along for the ride. It did not get involved in the units conversion.)
Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
Answer: each 0.5 hour or 30 minutes they travel 1 mile
Step-by-step explanation:
so just keep adding 1 mile each 0.5 hour
