Answer: 162.6cm
Step-by-step explanation:
4 boys have a mean height of 162cm. Their total height will be the average multiplied by the number of boys which will be:
= 162 × 4
= 648cm
A new boy with height of 165cm joined. This means that we now have 5 boys and their total height will be:
= 648cm + 165cm
= 813cm
The new mean height will be:
= Total height / Number of boys
= 813 / 5
= 162.6cm
195min/1.5 miles so 130 min / 1 mile or 2h 10min (2 1/6h)
Answer:
the scale is 630:1 = 0.16%
80inch^2 of 50400inch^2 however = 0.16%
Step-by-step explanation:
350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630
50400/9 =5600 we distribute
5600/80 = 7
showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th
1 = 630
7x9x 80 = 1/100 of 50400
0.01589 x 7x9x80x 7x9x80 = 80
Proves that every every 10000 the percentage goes down 0.00011%
12 months in a year. So 18 months= 1 year and 6 months. Izzys dog is 10 1/2= 10 years and six months. Then subtract 1 year and 6 months by 10 year and six months and it would be exactly 9 years older.
