Answer:
Step-by-step explanation:
25 total people
5 drank coffee and tea
tea drinkers only : 10 - 5 = 5
coffee drinkers only : 12 - 5 = 7
total people who drank anything : 7 + 5 + 5 = 17
number of people who drank neither : 25 - 17 = 8 <=====
The least common multiple is : 18
It is the lowest amount that can be reached.
Answer:
hi how are you wanna be friend
Step-by-step explanation:
Well...it says the sum of the angles measure 360...so lets set them equal to 360
40 + x - 10 + 1/3x + x - 20 = 360...combine like terms
2 1/3x + 10 = 360
7/3x = 360 - 10
7/3x = 350
x = 350/(7/3)
x = 350 * 3/7
x = 1050/7
x = 150 <=====
Consider a trapezoid GJKF with:
GH=JH (hypothesis)
FL=KL (hypothesis)
so HL is the median of trapezoid GJKF
so: HL=1/2(2.5+1.2)=1.85
