How to solve 0.5x +78.2 =287
Inessa [10]
You can subtract 78.2 from 287 to get the x value alone. Your new expression will look like this:
.5x=208.8
Next you divide by .5 (or multiply the reciprocal 1/.5 depending on how you were taught)
x=417.6

Hope that helps!!

A marvellous spatuletail is flying at an elevation of 4294 \dfrac29492​4, start fraction, 2, divided by, 9, end fraction meters.
user100 [1]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required is not stated.

<em>However, since it deals with height of different elevations and these heights are represented by fractions, a possible question could be to calculate the difference between both elevations </em>

Represent Marvellous Spatuletail with M and Asian crested ibis with A.

M = 4\frac{2}{9}

A = 10\frac{1}{4}

Calculating the difference (D).

To do this, we make use of absolute difference as follows:

D = |M - A|

Substitute values for M and A

D = |4\frac{2}{9} - 10\frac{1}{4}|

Convert fraction to improper numbers.

D = |\frac{38}{9} - \frac{41}{4}|

Take LCM

D = |\frac{38*4-41*9}{36}|

D = |\frac{152-369}{36}|

D = |\frac{-217}{36}|

Remove the absolute sign

D = \frac{217}{36}

D = 6\frac{1}{36}

<em>Hence, the difference between both elevations is: </em>6\frac{1}{36}\ meters<em></em>

Another possible question is to determine which of the two is flying at a higher elevation or lower elevation

We have.

M = 4\frac{2}{9}

A = 10\frac{1}{4}

Compare the integer parts of both fractions.

10 > 4

So, A flies at a higher elevation.

<em>Hence: Asian crested ibis flies at a higher elevation and Marvellous Spatuletail flies at a lower elevation.</em>

how to find the angel in trigonometry when all the lengths of the right angled triangle already given.
ozzi

Answer:

The three trigonometric ratios can be used to calculate the size of an angle in a right-angled triangle

Use rule ; SOHCAHTOA .Where sin x = opp/hyp

cos x = adj/hyp

tan x= opp/adj

Substitute the given values for the three sides

into any of the above rules

example = Hyp = 2\\opp = 1\\sin- x = 1/2\\x = sin^{-1} 1/2\\x = 30

Step-by-step explanation:
