Answer: if its true or false i think its false
Step-by-step explanation: u cant square root a negative number.
Inequality:
(3/10) ≥ k - (3/5)
Add 3/5 to both sides:
k ≤ (3/10) + (3/5)
Use LCD:
k ≤ (3/10) + (6/10)
Combine:
k ≤ 9/10
Area= LxW
=33x10
=330feet
Perimeter =L+W+L+W
=33+10+33+10
=86feet
Hope this helps :)
Let the weight of triangle be x units. You are given that the weight of square is 1 unit.
1) On the left side of the balanced beam you can see 3 triangles and 5 squares. The weight on left side is 3·x+5·1=3x+5 units.
2) On the right side of the balanced beam you can see 2 triangles and 7 squares. The weight on right side is 2·x+7·1=2x+7 units.
3) If the whole system is balanced, then the weights on left and right sides are equal:
3x+5=2x+7.
Solve this equation:
3x-2x=7-5,
x=2 units.
