Answer:
Option (1)
Step-by-step explanation:
Length of a rectangle = (5.9d + 8.3f) cm
Width of the rectangle = (7.3d + 2.2f) cm
Since formula to get he perimeter of a rectangle is,
Perimeter = 2(length + width)
= 2[(7.3d + 2.2f) + (5.9d + 8.3f)]
= 2(13.2d + 10.5f)
= (26.4d + 21f) cm
Therefore, Option (1) will be the correct option.
Answer:
2 Km
Step-by-step explanation:
Similar means they are of the same ratio
0.9 : 1.8 is a 1 : 2 ratio
That means
1 : d => is also 1 : 2 ratio
Therefore d=2
One, Three and Four are right answers.
Answer:
( -1/2, -2 1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
( -2+1)/2 = -1/2
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
( -1+-4)/2 = -5/2 = -2 1/2
( -1/2, -2 1/2)
