Answer:
225 p/p
Step-by-step explanation:
This design consists of 3 groups of participants, each with 25 members and three case studies, thus:
case (1) 17 inch ----------- 25 members
case (2) 18 inch ----------- 25 members
case (3) 21 inch ----------- 25 members
Total: case = 3 ----------- 75 members
Total pieces of paper = 3*75 = 225 piece of paper
Answer:
y - 6 = - 3(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (- 1, 6) , then
y - 6 = - 3(x - (- 1) ) , that is
y - 6 = - 3(x + 1)
Answer:
dimension are 350 m and 350 m and
area is 122500 m²
Step-by-step explanation:
Given data
perimeter is 700 m
to find out
the largest area and its dimensions
solution
we consider x and y are the sides
so area is xy
perimeter is 2x+ y = 700
so we can say y = 700 -2x
so area will be = x (700 - 2x)
area = 700x - 2x²
we take derivative here and equal to zero
dA/dt = 700x - 2x²
700 - 4x = 0
x = 700/4
x = 175
so will be
y = 700 -2x
y = 700 -2(175)
y = 350
so dimension are 350 m and 350m
area is 122500 m²
