You really need to guess 4+5
Answer:
72
Step-by-step explanation:
We need to multiply all of them because there are 3 choices for jackets, 6 for scarves and so on.
P(A)=0.2
P(B)=0.3
P(A and B)= 0.2 x 0.3=0.06
Answer:
x = 7
y = 25
Step-by-step explanation:
First, we know that x=7 because has the same hypotenuse (the long side) and also has a right angle.
Now, to find out y. The equation for discovering the hypotenuse is:
c = √(a² + b²)
C is the hypotenuse.
A is one of the shorter sides.
B is also one of the shorter sides.
NOTICE: THIS EQUATION ONLY WORKS FOR RIGHT TRIANGLES.
So, now you just need to fill the equation in:
c = √(7² + 24²)
c = √(49 + 576)
c = √(625)
c= 25
So, now we have y, the hypotenuse!
Hope this helped :D
Answer:
Step-by-step explanation:
Remove brackets:
Group the similar terms together:
Subtract 16 from both sides:
Divide both sides by -31:
