The best thing that would first be done in the aspect would be to first sum up the numbers that are in parenthesis.

Let's keep in mind that a (-)+(-) would equal a positive. This would mean that a negative number, plus another negative number would then be a positive number.

Your answer: <span>1.14200 </span>

<span>(-2.678) + 4.5 + (-0.68)= 1.142
since .1 is in the tenth place and 42 isnt greater than 50, the answer would be 1.1. </span>

The sum of three consecutive whole numbers is 183 find the numbers
sergiy2304 [10]

Answer:

let the no.s be : x, x+1, x+2

then,

=> x + x+1 + x+2 = 183

=> 3x + 3 = 183

=> 3x     = 183 - 3

=> x  =  180/3

=> x = 60

therefore,  the whole no.s are 60, 61, and 62

In triangle ABC, c is the hypotenuse, 0=25°, and b =3, Find the length of c ?
Charra [1.4K]

Answer:

\large\boxed{c\approx3.31}

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

\cos\theta=\dfrac{b}{c}

We have:

\theta=25^o\to\cos25^o\approx0.9063\\\\b=3

Substitute:

\dfrac{3}{c}=0.9063

\dfrac{3}{c}=\dfrac{9063}{10000}          <em>cross multiply</em>

9063c=30000          <em>divide both sides by 9063</em>

c\approx3.31
