The correct answer of 1/3 is the decimal form of it which is 0.3 repeated (you can put a line on top of the 3). If not just leave it as 1/3 it is simplified as a fraction.
1. A = 1/4s squared, square root of 3
2. A = bh
3. A = pi(r) squared
4. A = 1/2 h (b1+ b2)
5. C = pi(d)
6. A = base x altitude
7. A = 1/2(ap)
8. A = 1/2(bh)

Answer:
x = 1.5 ; y = -0.5
Step-by-step explanation:
2x + 4y = 1 ---------------------(i)
3x - 5y =7 ----------------------(ii)
(i) * 5 10x + 20y = 5
(ii)*4 <u> 12x -20y = 28 </u>
add, 22x = 33 { here y will be eliminated}
x = 33/22 = 3/2
x = 1.5
Put the value of x in equation (i)
2*1.5 + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4 = -1/2
y = -0.5
Since the diver is 19 metres below the surface of the water, then he will need to travel 19 metres to reach the surface.
