$800 not including rental fee.
200 miles divided by $0.25
So we know the total distance is 65 miles.
Let d1 = distance to 1st delivery from distribution center
d2 = distance to 2nd delivery from 1st delivery site
d3 = distance to 3rd delivery from 2nd delivery site
d4 = distance from 3rd delivery site back to distribution center.
So total distance D = d1 + d2 + d3 + d4 = 65
We know that d1 to d2, d2 to d3 and d3 to d4 each differ by 1/2 a mile.
This means that
d2 = d1 + 1/2
d3 = d2 + 1/2 = (d1 + 1/2) + 1/2 = d1 + 1
d4= d3 + 1/2 =d1 + 1 + 1/2 = d1 + 3/2
Adding all these distances:
d1 + d2 + d3 + d4
= d1 + (d1 + 1/2) + (d1 + 1) + (d1 + 3/2)
= 4d1 + 3 = 65
d1 = (65 - 3)/4
So the distance to the first delivery, d1 is (65 - 3)/4.
Does that make sense?
Answer:
Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 7² = 8², that is
x² + 49 = 64 ( subtract 49 from both sides )
x² = 15 ( take the square root of both sides )
x =
Thus
sinΘ = =
Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12
If x=3, the perimeter is 16*3 +12 = 60 inches.
