Answer:
47, 76, 123
Step-by-step explanation:
Fibonacci Sequence
Answer:
C
Step-by-step explanation:
Use sine rule
17/sin130=5/sinB
(5×sin130)÷17=sinB
sinB=0.2253017892
B=sin^-1ans above
=13.4
A=(130+13) subtracted from 180=37°
a/sin37=17/sin130
=13.4
Answer: =−14a3−2a2+12
Step-by-step explanation:
−5a3−7a2+3−9a3+5a2+9
=−5a3+−7a2+3+−9a3+5a2+9
Combine Like Terms:
=−5a3+−7a2+3+−9a3+5a2+9
=(−5a3+−9a3)+(−7a2+5a2)+(3+9)
=−14a3+−2a2+12
Answer:
=−14a3−2a2+12
Answer:
4/27=14.8%
Step-by-step explanation:
In order to solve this, we have to see first each option possible, there are 2/3 of possibilities that a random Entrée ends up being Chicken Cutlet or Lasagna, then you have again 2/3 chances to get milk or water, and as you only want fruit the chances are 1/3 that you get that.
In order to calculate if this could happen at random we have to multiply all of the odds:
So we know that for every 27 times you pick a lunch at random, 4 times it will not have the Veggie Wrap, contain milk or water, and will have fruit as the snack.
We set up an equation: ?/43 -87= -75
⇒ ?/43= -75+ 87
⇒ ?/43= 12
⇒ ?= 12*43
⇒ ?= 516
The unknown number is 516~
