Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solving in steps</u>
- 1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
- 2. ⇒ z = - (2.5 - 0.72)
- 3. ⇒ z = - 1.78
The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
gcd(12, 16) = 4 I hope I was help full
Answer:
34000cm or 340m
Step-by-step explanation:
We have to find total surface area.
dimensions of 1 wooden box =
l = 1m = 100cm
b = 80cm
h = 25cm
∴ In the case of 2 =
l = 100cm
b= 80cm
h = 25 + 25 = 50cm
T.S.A = 2(lb + lh + bh)
= 2(100*80 + 100*50+ 80*50)
= 2(8000+5000+4000)
= 2*17000
= 34000cm
= 340m
