Answer:

Step-by-step explanation:

This is the equation. Read it carefully.

1/2 * 1/7 T = 1/3 * 1/5 * 90   Reduce

(1/14) * T = 1/15 * 90

1/15 * 90 = 6

(1/14)*T = 6                          Multiply both sides by 14

T = 14 * 6

T = 84

Answer:

  √55 ≈ 7.4

Step-by-step explanation:

The easiest way to find the square root of 55 is to use a calculator.

  √55 ≈ 7.4161984871

Rounded to the nearest tenth, this is ...

  √55 ≈ 7.4

__

You can make a first approximation of the root by linearly interpolating between the roots of the perfect squares* on either side of 55.

  √49 = 7

  √64 = 8

  √55 ≈ 7 +(55 -49)/(64 -49) = 7 6/15 = 7 2/5

  √55 ≈ 7.4

_____

* For numbers greater than 3.3, this sort of approximation will give the value of the root accurate to the nearest tenth. The approximation is better for larger numbers.
