<h3>
Answer: 139.5</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(55) = 80/x
x*cos(55) = 80
x = 80/cos(55)
x = 139.4757 approximately
x = 139.5
A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
Answer:
<h2><u><em>
Two-thirds times one-eighth = Start Fraction 1 Over 12 End Fraction
</em></u></h2><h2><u><em>
Three-halves times 8 = 12</em></u></h2>
Step-by-step explanation:
3.14 x 10^-3 = 0.00314...since ur exponent is negative, ur gonna move the decimal 3 spaces to the left...if the exponent would have been positive, u would have moved the decimal 3 spaces to the right.
So you just plug in 3 into variable p in the equation. C=12(3)+5
C=26+5
C=31
