Answer:
Am = 1500 cm²
Step-by-step explanation:
If you mean leg around the right angle a = 3 cm and b = 5 cm then :
Formula for calculating area of the right triangle is:
A = a · b / 2 since we have 200 triangles, area of the mosaic is:
Am = 200 · A = 200 · a b / 2 = 200 · 3 · 5 / 2 = 1500 cm²
Am = 1500 cm²
God with you!!!
Answer: y=x-6
Step-by-step explanation:
2x-2y-12=0
1. Add 2y to both sides:
2x-12=2y
2. Divide both sides by 2
x-6=y
Answer:
ariel is incorrect because 2 5/8 is equal to 2.63
Step-by-step explanation:
Gradient of line = (change in y)/(change in x) = -3/2
equation of a line = y-y1 = m (x-x1) = y-0 = -3/2(x-2)
y=-3/2x + 3
I'm going to take a guess and say you missed the neg. sign in C?
