Answer:
The scale factor is 3
Step-by-step explanation:
The reason is that 12, 15, and 9 equal 4, 3, and 5 if divided by 3
Answer:
0.75
Step-by-step explanation:
0.75 is 3/4th of 1. 0.4 is 4/10 = 2/5 (40%) of 1. 75 is bigger than 40.
Answer:
2340 m^2
Step-by-step explanation:
The area of kite = multiply the lengths of the two diagonals and divide by 2
The top left triangle:
Using Pythagorean theorem:
c^2 = a^2 + b^2
so
b^2 = c^2 - a^2
b^2 = 51^2 - 24^2
b^2 = 2601 - 576
b^2 = 2025
b = 45
Top right triangle:
Using Pythagorean theorem:
c^2 = a^2 + b^2
so
b^2 = c^2 - a^2
b^2 = 53^2 - 45^2
b^2 = 2809 - 2025
b^2 = 784
b = 28
so the two diagonals:
24 + 28 = 52 m and 45 + 45 = 90 m
Area of the kite:
A = 52 x 90 / 2
A = 2340 m^2
Answer:
The length of the wall would be 12 cm
Step-by-step explanation:
step 1
we know that
On a blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm
so
The actual length of the wall is equal to ------> 9*4=36 ft
step 2
If the scale of the blueprint were 1 cm = 3 ft
then
The length of the wall in the new blueprint would be ----> 36/3=12 cm
