Answer:
b. 28000 times 400 equals 11200000
c.9000 times 60 equals 540000
d.900 times 600 equals 540000
e. 40000 times 500 equals 20000000
Step-by-step explanation:
3 decimal places would be where the 9 is, since the next number is 8 , the 9 would become a 0 and the number before it (5) would become a 6
so it would be 977.260
Answer:
Answer: Pythagoras law:h²=p²+b²
needed to apply
4²+8²=12²
80≠144 not a right angled triangle
again
2²+√5²=3²
9=9/
<em><u>side</u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>right</u></em><em><u> </u></em><em><u>angled</u></em><em><u> </u></em><em><u>triangle</u></em>
again
2²+2²=(√8)²
4+4=8
8=8
<em><u>side are a right angled triangle</u></em>
