Answer:

  False

Step-by-step explanation:

 counterexample: 3 + 7 = 10 . . . . not divisible by 4

The statement is FALSE.

__

An odd number can be represented by ...

  2n+1 . . . . where n is any integer

Then a different odd number can be represented by ...

  2m +1 . . . . where m is any integer

The sum of these numbers will be ...

  (2n +1) +(2m +1) = 2n +2m +2 = 2(n +m +1)

This will be divisible by 2 for any integers m and n, but will only be divisible by 4 if exactly one of the integers m and n is odd.

Please Help! :) <br> Solve for X. The polygons in each pair are similar.
Diano4ka-milaya [45]

Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

4x-5*2.5=14

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

4x-5=5.6

Next, add 5 to both sides:

4x=10.6

Then divide both sides by 4:

x=2.65

Please help me find the same denominator
Lelechka [254]

Answer:

\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}

let us first start with some basic information ~

A fraction can be represented as \frac{x}{y}\\ where ,

x is the numerator and y is the denominator !

the question asks us to do something that will help us get same denominator for both the terms !

so let's see what we should do in such a case ~

\frac{9}{10}  \: and \:  \frac{7}{8}  \\ \\ \\ lets \: make \: the \: denominator \: of \: both \\ the \: terms \: reach \: 80 \: , \\  \\ \bold\orange{ \implies \: \frac{9}{10}  \times  \frac{8}{8}  = }\bold\red{ \frac{72}{80}}  \\  \\\bold\orange{ \implies \:  \frac{7}{8}  \times  \frac{10}{10}  =}\bold\red{  \frac{70}{80}}

and we're done !

let's add some more info to be lil more clear ~

while converting the denominator of both the terms , we must multiply the same number ( this number refers to the one we'll have to multiply to the denominator to obtain the desired result ) with the denominator as well as with the numerator !

hope helpful :D

Damm [24]

Answer:

42.1 degrees

Step-by-step explanation:

- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h

- this means, sin x = 0.67

so, x = sin^{-1(0.67)  {sin inverse}

x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
