A) QR/PQ = (√3)/2 . . . . . TRUE
B) PR/PQ = 1/2, not (√3)/2 . . . . false
C) QR/PR = (√3)/1 . . . . . TRUE
D) PQ/PR = 2/1, not √3 . . . . . . .false
E) QR/PR (see C) . . . . . . . . . . .false
F) PQ/PR = 2/1 . . . . . . . .TRUE
Answer:
10.5 cm
Step-by-step explanation:
12÷9= 1.3 (1dp)
14÷(12÷9)= 10.5cm

32^(-1/5)
1/32^(1/5)
^1/5 means 5√32 = 2
so the answer is 1/2 or 0.5
The blank is 123 because 32/41=96/123.
your multiplying 32 by 3 to get 96.
That means you have to multiply the bottom by 3 too.
41 multiplied by 3 is 123.
And 123 is the blank.
