Answer: A.
Step-by-step explanation: yes
Answer:
3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.
Step-by-step explanation:
I think that explanation is obvious
7x9=63
63÷2= 31.5x4
126= area of the triangles
7x7= 49= area of the square.
126+49= 175 ft
12 2 +16 2 = D2
D2= 144+256
D2= 400
D2= 400
