I need this asap!! will give brainliest and a thanks!

Tess = 71 y/o

Nina = 63 y/o

Katy = 55 y/o

Step-by-step explanation:

First step: divide their age equally.

189÷3 = 63 years old / person

Second step: calculate the different between their age.

Tess>Nina>Katy

Different between:

Katy and Tess

= 16 years

Nina and Katy

= 8 years

Tess and Nina

= 16–8

= 8 years

Third step: Calculate their age.

Tess = 63+8

= 71 years old (because she is 8 years older than Nina and 16 years older than Katy)

Nina = 63 years old ( it doesn't change because she is in the middle)

Katy = 63–8

= 55 years old (because she is 8 years younger than Nina and 16 years younger than Tess)

To confirm, you can sum their age and check the age differences like what have been told in the question either it is correct or not.

71+63+55

= 189 years

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm

1/4 is the asnwer cuz 5/20 is the faction
