The unknown number is 1/2 or 0.5.
ex: 4x+6=8
For it to be non-linear, the rate of change cannot be constant. For the first table the rate is a constant 1 and the second table has a constant rate of -1. The 3rd and 4th tables have no constant rate and thus are non-linear.
The 4th table is increasing while the 3rd table is decreasing.
So the 3rd table, Set C, is the only non-linear negative association between x and y.
Answer:
20% decrease
Step-by-step explanation:
Start by dividing 40 by 50.
40/50 = 0.8
0.8 is the decimal form of 80%. So now we know that 40 is 80% of 50. This means that the remaining 20% is the difference between the books read in November and December.
Answer:
If The ratio of the width to
the length of a rectangle is 4:15
let width is 4x
let length is 15x
perimeter of the rectangle = 2(length + width)
= 2(15x + 4x)
= 2(19x)
=38x
If the perimeter of the rectangle is 152 meters.
152 = 38x
x= 152/38
x = 4
so,
width is 4x = 4(4) = 16m
length is 15x = 15(4) = 60m
The area of the rectangle = length. width
= 60m.16m
= 960 m^2
