Answer:
FIRST NUMBER IS 20
AND
SECOND NUMBER IS 45
Step-by-step explanation:
LET THE RATIO BE X
FIRST NUMBER = 4X
SECOND NUMBER = 9X
A/Q,
=}4X - 5 / 9X - 5 = 3 / 8
CRISS CROSS,
=}8 ( 4X - 5 ) = 9X - 5 ( 3 )
=}32X - 40 = 27X - 15
=}32X - 27X = - 15 + 40
=}5X = 25
=}X = 25 / 5
=}X = 5
THEREFORE,
FIRST NUMBER
=} 4X
=} 5 × 4
=} 20
SECOND NUMBER
=} 9X
=} 5 × 9
=} 45
77.2%
To find the probably and at least on you must find the probability of none and subtract from one.
The probability of none can be found like so:
(5+6 over 5+6+7)^3 = .228
1 - .228 = .772
Hope this helps!
Answer:
B = 38°
Step-by-step explanation:
A straight angle is 180°. If your four angles total a straight angle, then ...
60 +2x +3x +25 = 180
95 = 5x . . . . . . subtract 85
x = 19 . . . . . . divide by 5
2x = 38 . . . . . angle B is 38°
