How to calculate square root 1.4 without calculator

Mathematics
1 answer:
Oxana [17]3 years ago
6 0

Answer:

Approximate only

Step-by-step explanation:

the perfect square smaller than 1.4 is 1, because 1^2 =1

Take the difference between the two, 1.4 -1 = 0.4

Put the whole with 1. the part will be as follow:

1 \frac{0.4}{double~the ~whole} =1\frac{0.4}{2}

=1+0.2= 1.2

Note: just approximate!! with calculator, it is 1.18321

Write a proportion for the statement.<br> 40 is to 10 as 32 is to 8.

  All proportions have <u>this</u> <u>form</u>:

  \sf{\dfrac{a}{b}=\dfrac{c}{d}}, Where \sf{\dfrac{a}{b}} is equal to \sf{\dfrac{c}{d}}.

 If \sf{\dfrac{a}{b}\neq\dfrac{c}{d}}, it's <u>not</u> a proportion.

_________________________

  Here we have two pairs of numbers:

40,10 and 32,8.

Written As a <u>proportion</u>, they <em>look like</em> :

\sf{\dfrac{40}{10}=\dfrac{32}{8}}

Hope this made sense to you :)

.......... is the slope zero
Eddi Din [679]

Answer:


Step-by-step explanation:

OK... You have to use this formula: <u>Y2 - Y1</u>

                                                          X2 - X1

  • -2 represents X1
  • 7 represents Y1
  • 2 represents X2
  • -5 represents Y2    

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 7</u>

2 - - 2

<u>-12</u>

-2

Simplify by dividing both -12 & -2 by 2: <u>-6</u>

                                                                 -1

It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...

                -1
