Answer:
A) Perimeter = 9.6 inches
Area = 5.76 inches ^2
B) Perimeter = 57.6 mm
Area = 207.37 mm^2
Step-by-step explanation:
The perimeter and the area of the object in the scale drawing.
Perimeter = 2.4 x 4 = 9.6 inches
Area = 2.4 × 2.4 = 5.76 inches ^2
Then find the perimeter and area of the actual object.
If 1 inch = 6mm, and we have 2.4inches, then we need to multiply: 2.4 × 6 = 14.4
So each side of the square is 14.4 mm long
The perimeter of a square is 4 equal sides, so you will need to multiply 14.4 and 4
14.4×4 = 57.6mm
The area of a square is the length times its width. So that means to find the area, you will need to multiply 14.4 and 14.4 together.
14.4 × 14.4 = 207.36mm^2
Answer: Masha needs 40 more minutes to complete the path.
Step-by-step explanation:
So if Dina is cycling speed is 10km per hour that means it will take Dina 2 hours to completed the the path.
Here; =
10x = 20
x= 2
But since Masha still have 4 more km to go you will add 20 + 4 =24
=
10x= 24
x= 2.4
6x - 3y = 12
3y = 6x -12
y = 2x -4
slope = 2
Answer:
First of all use 2 to multiply the numbers in the bracket which will be 2x-42=25....then collect like terms which will be 2x=25+42 which will be 2x=67 then 67/2=33.5 or 33whole number 1/2.
