Answer:
1421 minutes
Step-by-step explanation:
(84.48-28)/.04=M
84.48-28=56.48
56.48/.04=1421
2, 6, and 7 are the domain because they are in the "x" spot
Answer:
2,052,086,400.
Step-by-step explanation:
Permutation
Pr = n! / (n-r)!
30P5 = 30! / (30-5)
30P5 = 30x29x28x27x26x25! / 25!
(Just cancel the 25! on the numerator and denominator for easier solving.)
30P5 = 30x29x28x27x26
30P5 = 17,100,720.It is not the final answer because we can still arrange the 5 winners.
5! = 5×4×3×2×1 = 12017,100,720 × 120 = 2,052,086,400
1/2(x - 3) = 2/3(x - 8)
<em><u>Distributive property on both sides.</u></em>
0.5x - 1.5 = 0.7x -5.3
<em><u>Add 5.3 to both sides.</u></em>
0.5x + 3.8 = 0.7x
<em><u>Subtract 0.5x from both sides.</u></em>
3.8 = 0.2x
<em><u>Multiply both sides by 5.</u></em>
x = 19 (This is your answer.)
