Answer: 72
Step-by-step explanation:
Given: Choices for hats = 3
Choices for scarves = 8
Choices for nose = 3
Using the Fundamental principle of counting, the number of different snowmen she can make = (Choices for hats) x (Choices for scarves) x (Choices for nose)
= 3 x 8 x 3
= 72
Hence, the number of different snowmen she can make = 72
Here, the equation would be: 50t + 60t = 247.5
They will take same time, as they started their journey at a time.
Value of t, = 247.5/110 = 2.25
So, Armand traveled = 2.25 * 50 = 112.5
Jill traveled = 2.25 * 60 = 135
According to all of that information, Your Answers would be Option B, C & E
Hope this helps!
Okay so question is
x^2-10x + 26 = 8
Lets simplify it
x^2-10x+18=0
Let's solve your equation step-by-step.<span><span><span><span>x2</span>−<span>10x</span></span>+18</span>=0
</span>Step 1: Use quadratic formula with a=1, b=-10, c=18.<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a
