Answer: 87.5
Step-by-step explanation:
The Area formula for a Trapezium is
depicted in the two picture below.
As seen in the picture Area equals
A+B(h) all divided by 1/2 or simplistic terms 2.
A+b
A= ---------- (h)
2
So we need to plug our information in
as Depicted in the picture measurement A is first top side
And B is bottom base
so h IS the height of the figure. Its the middle line in the middle of the figure.
10+15
A= ________(7)
2
10+15=25
25*7=175
175/2=87.5
So your answer is
Area of ABCD is 87.5
Let a and b be the numbers,then a+b=32,b=32-a
ab=-320
a(32-a)=-320
32a-a^2=-320
a^2-32a-320=0
a^2-40a+8a-320=0
a(a-40)+8(a-40)=0
(a-40)(a+8)=0
a=40 or-8
when a=40,b=32-40=-8
when a=-8,b=32-(-8)=32+8=40
so numbers are 40 and -8
Answer:
x is less then or equal to -3
x<-3 (the < has to have a line underneath)
Step-by-step explanation:
In a research of investigating the effects of working in crowded versus uncrowded conditions on the job satisfaction of employees in a variety of work setting , working is a depending variable and crowding is an independent variable.
Given aim of the research is to investigate the effects of working in crowded conditions and uncrowded conditions.
We know that depending variable is a variable whose value is dependent on the other variable. Independent variable is a variable whose value does not dependent on the other variables.
In the given question working may be affected negatively in crowded environment means there will be less work in crowded environment and more work in uncrowded environment.
Hence the depending variable in research is working.
