Mike measured the stage where his band was going to play to determine if it is a right triangle. Does the stage with side length

katrin [286]

Answer:

let

hypotenuse[h]=60ft

base[b]=36ft

perpendicular [p]=48ft

by using Pythagoras law

p²+b²=h²

48²+36²=60²

2896≠3600

since p²+b²≠ h²[so the stage is not in a right angled triangle]but it is scalene triangle

The mean age of 9 women in an office is 27 years old.

Veronika [31]

26 to nearest year

We require the total of the sums of ages for both groups before calculating the mean for all 16

using mean = $\frac{sum}{count}$

Women

27 = $\frac{sum }{9}$ ( cross- multiply )

sum = 9 × 27 = 243

Men

25 = $\frac{sum}{7}$ ( cross- multiply )

sum = 7 × 25 = 175

Total sum of all 16 = 243 + 175 = 418

mean = $\frac{418}{16}$ = 26 ( to nearest year )
