Answer:
3x + 4.5x + 1 = 28
3.6 seconds
Step-by-step explanation:
Initial distance apart = 1 foot
Student A:
Walk rate = 3 ft per second
Student B:
1.5*3 = 4.5 ft per second
How long it will take to be a total of 28 feets apart
Distance = speed * time
Let time = x in seconds
Student A distance = 3x
Stident B distance = 4.5x
Initial distance = 1 foot
3x + 4.5x + 1 = 28
7.5x = 28 - 1
7.5x = 27
x = 27/ 7.5
x = 3.6 seconds
Answer:
4.33333
Step-by-step explanation:
Answer:
47.6m.
Step by step solution:
Perimeter of a triangle = base + 2 . length____(1)
Area of a triangle = 1/2 . base . diagonal
108 = 1/2 . base . 15
multiplying both sides by 2:
216 = 15 . base
dividing both sides by 15:
base = 14.4m
But the diagonal divides the triangle into two
right angle triangles each with the same length (hypotenuse),base and diagonal(height).
Taking one right angle triangle:
And using pythagoras theorem;
length² = base² + diagonal ²
length² = 7.2² + 15²
Note: Base of each right angle triangle is 7.2 which would sum up to be 14.4 the base of the full triangle.
length² = 276.84
taking the square root of both sides:
length = 16.6m
Putting the values of the base and length into equation (1).
Perimeter of the triangle = 14.4 + 2 . 16.6
Note: We are dealing with the whole triangle
now hence the base is 14.4m.
Perimeter of the triangle = 14.4 + 33.2 = 47.6m.
