Range:5-24
Median: 10
Mean: 8.76
Answer:
The shorter piece x = 8.4 in
The longer one y = 15.6 in
Step-by-step explanation:
If we cut a string length L in to unequal pieces we get two pieces
first one with length x and the other one with length y
Let call x the smaller piece, then y = L - x will be the longer one
If x = 35 % then
x = 0,35* L and
y = L - x = L - 0,35*L ⇒ y = 0,65 L ⇒ y = 0.65*24
Now if L = 24 in
x = 0,35*24 ⇒ x = 8.4 in
and
L - x = 0.65*L ⇒ L - x = 0.65*24 y = L - x = 15.6 in
as way of verification you can add the length of the two pieces and find:
8.4 + 15.6 = 24 in
Answer:
6.67 ft
Step-by-step explanation:
Let d = distance
and w = weight
Then d = k/w
or dw = k
Let d1 and w1 represent Roger
and d2 and w2 represent Ellen. Then
d1w1 = d2w2
Data:
d1 = 6 ft; w1 = 120 lb
d2 = ? ; w2 = 108 lb
Calculation:
6 × 120 = 108d2
720 = 108d2
d2 = 720/108 = 6.67 ft
Ellen must sit 6.67 ft from the fulcrum.
