Answer:
50.41 minus 1.71 is 48.70 divided by 5 is 9.74
The nearest thousand is 547,000
<span> Slope = 1.000/2.000 = 0.500 x-intercept = 5/-1 = -5.00000<span> y-intercept = 5/2 = 2.50000</span></span>
Answer:
a) 12cm
b) 360cm²
c) 2160cm cubed
Step-by-step explanation:
a)
you would use Pythagoras theorem for A
so half of 18 is 9
15² - 9² = 144
the square root of 144 is 12
the height is 12cm
b)
18 x 20 = 360cm²
c)
csa x L
csa = b x h divide by 2
18 x 12 = 216cm²/2 = 108cm²
108xm² x 20cm = 2160cm cubed
