2.0625
Step-by-step explanation:
8.25%=0.0825
0.0825*25=2.0625
There is only one solution
Answer: 2/3x
Step-by-step explanation:
First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with
y = 3/2x - 1/2
Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x
Answer: x = 21
Step-by-step explanation:

Area of the electronic board is 9000 cm2
Step-by-step explanation:
Write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.
The Electronic board always seems like a rectangular shape
Length= scale÷Actual = 5/36 = 5×36 = 180cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Area of Rectangle = legnth × width
= 180cm × 50cm = 9000 cm2

Area of the electronic board is 9000 cm2
