They can rent it for 7 hr. $20.60-$4.50=$16.10. $16.1 divided by $2.30= 7
Answer:
The formula is (base x height x 1/2) OR ([base x height] / 2)
Hope that helps!
Step-by-step explanation:
The smaller angle = 66°
let x be the angle then
(180 - x) + 9 represents 9 more than half of it's supplement
equating the 2 expressions gives
x =
(180 - x ) + 9 → (distribute and simplify right side )
x = 90 -
x + 9 = 99 -
x
add
x to both sides
x = 99
multiply both sides by 2 and divide by 3 gives
x = 66
the supplement of 66° is 180° - 66° = 114°
Thus the smaller angle is 66°
(2X-3)(4-3X)
=8X-6X²-12+9X
=-6X²+17X-12
That's your answer.
Well in this question there is lots of unnecessary information. u only need to know as total they need to pay300. then there're 4people in total in the trip, 300/4=75
