Answer:
117
Step-by-step explanation:
Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)
a²+b²=c²
A= 75
B= 90
C is always the hypotenuse.
75²+90²= c²
5,625+8,100= 13,725
√13,725= 117.15374513859981591194584103639
To the nearest whole number: 117
To the nearest tenth: 117.2
Hope this helps!
Answer:
Step-by-step explanation:
Let w represent width of the rope-off section.
We have been given that a manager needs to rope off a rectangular section for a private party the length of the section must be 7.6 m the manager can use no more than 28 m of the rope.
We will use perimeter of rectangle formula to solve our given problem. We know that perimeter of a rectangle is equal to 2 times the sum of length and width.
Upon substituting our given values, we will get:
Since the manager can use no more than 28 m of the rope, so perimeter of rope-off section should be less than or equal to 28 meters.
We can represent this information in an inequality as:
Therefore, our required inequality would be .
Let us find width as:
Therefore, the width of the rope-off section should be less than or equal to 6.4 meters.
4x -2(3x+7)
Use the distributive property:
4x - 6x -14
Combine like terms:
