Answer:
x= Multiplication
Step-by-step explanation:
1 x +2 -3 =8
Answer:
Option B
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
By substituting the values in the given expression,
7² = x² + 2²
49 = x² + 4
x² = 49 - 4
x² = 45
x = √45
x = 3√5
x = 6.7 ft
Option B will be the correct option.
Answer:
no
Step-by-step explanation:
57 isnt a prime number
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.
I think its either 9 or 10
