Answer:
Step-by-step explanation:
As each step has the same depth and rise, they are respectively 1.2/4=0.3m and 1.8/4=0.45m.
Dividing the steps along the dotted lines, the total rise of the 4 concrete steps = (1+2+3+4)*0.45
= 4.5m
Total concrete volume = total rise * depth * width
= 4.5*0.3*1.8
= 2.43m^3
I think is a because if you see and do it you could see
Answer:25
Step-by-step explanation
5 x 5 = 25. Got this problem correct on Imagine Math.
58 <span>≤ ($9 +<em> t</em> ) + ($21 + <em>t </em>)
so, n </span><span>≤ (<em />$58 + <em>t</em> ) + ($21 +<em> t</em> )</span>
P(P then C)=(7/10)(3/12)
P(PthenC)=21/120
P(PthenC)=7/40
