(6-3)^3: [2^2]^5=3^3:4^5=27/1024
Answer:
X=6 and Y=3
Step-by-step explanation:
Use SOHCAHTOA, SOH, Sin=Opposite/Hypotenuse, Therefore Sin60°=(3√3)/x ; Xsin60°=3√3 and Sin60° without using 4figuretable or calculator is √3/2, Now x=3√3 ÷√3/2 ;. therefore X=3√3×2/√3= 6. X=6 . Using Pythagoras theorem, 6²={(3√3)² +y²}. Y²= 36-27=9. Y=√9, Y=3. Therefore X=6 and Y=3.
2x + 4y = 38......multiply by -5
10x + 3y = 105
-----------------
-10x - 20y = - 190....result of multiplying by -5
10x + 3y = 105
----------------add
-17y = - 85
y = -85/-17
y = 5
2x + 4y = 38
2x + 4(5) = 38
2x + 20 = 38
2x = 38 - 20
2x = 18
x = 18/2
x = 9
solution is : (9,5)
Answer:
Step-by-step explanation:
"mutually exclusive" means "cannot happen at the same time." There's no "union" (no A ∩ B). The probability of this "union" is zero.
