1) 7/8-x-5/12=5/24
2) 11/24-x=24
3) -x=5/24-11/24
4) -x=-1/4
ANSWER: x=1/4
Answer:
1110
Step-by-step explanation:
Let x = price of the ticket before tax
We know the ticket plus the tax = 1232.10
x + x*11% = 1232.10
x+.11x = 1232.10
1.11x = 1232.10
Divide each side by 1.11
1.11x/1.11 = 1232.10/1.11
x=1110
10sinx-6=0
sinx=6/10=3/5, not negative three out of five.
yo use a calculator' sin3/5=sin0.6, if 0≤x≤2π, x≈37 or 127 (37+90=127, sine is positive in first and second quadrant)
Answer:
383.4 km
Step-by-step explanation:
The interior angle at the first turning point in the triangular flight path has measure 270° -215° = 55°. The law of cosines can be used to find the length of the final leg:
c² = a² +b² -2ab·cos(C)
c = √(125² +137² -2·125·137·cos(55°)) ≈ √14749.01 ≈ 121.4
The total length of the journey is then ...
round trip = 125 +137 +121.4 = 383.4 . . . km
___
In the attachment, the number at the bottom is the sum of the lengths of the two adjacent sides. The total length is then 125 +258.4 = 383.4 km.
