I think you want diagonal "ae" right?
According to this site:
https://www.easycalculation.com/area/learn-cube.php
a cube diagonal = square root of 3 * side length
square root of 3 * 45 =

For this case, the first thing we must do is define variables:
x: rental charge per day
y: rental charge per mile
We write the system of equations:
3x + 300y = 81
5x + 600y = 145
Solving the system we have:
x = 17
y = 1/10
Answer:
rental charge per day = 17 $
rental charge per mile = 1/10 $
Answer is C) 8/19
you do ((2*8)+3)/8
making it 19/8
and the reciprocal is the opposite of that answer, so 8/19
Answer:
-x-9
Step-by-step explanation:
-(x+9)
The "-" at the beginning can be rewritten as -1
=-1(x+9)
To distribute -1 into the parentheses, multiply each value inside by -1
=(-1)(x)+(-1)(9)
=(-x)+(-9)
= -x-9
I hope this helps!
Answer:
101.98 yards.
Step-by-step explanation:
Please refer to the diagram that I drew (sorry for the messiness; I do not own a stylus and so I was using my mouse to try to draw it).
Since the triangle is a right triangle, you can use SOH CAH TOA. In this case, you are trying to figure out the opposite length, but you are given the adjacent. So, we will use tangent to solve this (TOA = Tangent, Opposite over Adjacent).
The angle is 22.6 degrees, and the tangent of the angle is equivalent to the opposite length, x, divided by the adjacent length, 245 yards.
tan(22.6) = x / 245
x / 245 = tan(22.6)
x = tan(22.6) * 245
x = 0.4162598242 * 245
x = 101.9836569
So, you are about 101.98 yards from the cabin.
Hope this helps!
