Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters
HOPE IT HELPED !!
These two angles are congruent so
12x + 3 = 11x + 9
X = 6
Plug in 6 so 12(6)+3=75
Both angles measure 75 degrees
It would be: 1- 5/8 = 3/8
3/8 * 10 = 30/8 = 3.75 inches
Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88
Answer:
total number of brown sugar cubes = 3
total number of white sugar cubes = 1
total number of sugar cubes = total no of brown sugar cubes + total no of white sugar cubes = 3 + 1 = 4
probability to select one brown sugar cube = total number of brown sugar cube / total number of sugar cube = 3/ 4
therefore the probability of selecting a brown sugar cube is 3/4 or 0.75
