Answer:
6.21
Step-by-step explanation:
Answer:
55%
Step-by-step explanation:
Express the ratio in fractional form, that is
11 : 20 =
To convert the fraction to a percentage , multiply by 100%
= × 100% ( cancel 20 and 100 by 20 )
= 11 × 5 %
= 55%
<span>the question does not present the options, but this
does not interfere with the resolution</span>
we know that
Perimeter of rectangle=2*[W+L]
where
L is the length of rectangle
W is the width of rectangle
Perimeter=18 cm
so
18=2*[W+L]-----> divide by 2------> 9=W+L
Let
x-------> L
y-------> W
then
x+y=9
using a graph tool
see the attached figure
the slope of the line is m=1
the x intercept is the point (9,0)
the y intercept is the point (0,9)
Y=mx+b
m=slope
b=yint
given
m=6
b=-9
y=6x-9
graph the point (0,-9) and (1,-3) and connect the lines
