Find the value or y, rounded to the nearest tenth.

12.7
13.3
11.7
12.4

D. 12.4

Step-by-step explanation:

We are given the figure with measurements,

PT = y

PA = 7

AB = 15

where P, T, A and B are located as in the figure below.

Now, we know the formula that,

i.e.

i.e.

i.e.

i.e. y= ± 12.4

Since, the length cannot be negative.

Thus, option D i.e. y = 12.4 is correct.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
