What is 3 1/2+4 5/6?

1 answer:

3 0

3 1/2 + 4 5/6

Multiply 3 1/2 by 3/3 so that both fractions have "6" as their bottom number (denominator).

3 1/2 × 3/3 = 3 3/6

So, our new question is this : 3 3/6 + 4 5/6

Basically, when both fractions have the same bottom number (denominator), all you have to do is add the top numbers (numerators) as well as adding the whole numbers. Remember, you always keep the bottom number (denominator) the same when you are adding or subtracting.

Whole number : 3 + 4 = 7

Numerator : 3 + 5 = 8

Denominator : 6

So, our answer is 7 8/6

However, because the top number (numerator) is greater than the bottom number (denominator), you have to make the whole number larger.

So, our answer is 8 2/6

Simplify.

8 1/3

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 22 feetfeet less than th

ivann1987 [24]

So basically the ladder is creating a right triangle with the ground and the wall. Ladder is the hypotenuse (h), building = b, ground = g
b = h - 22 ft
g = 1010 ft
use Pythagorean Theorem to determine the length of h:
${c}^{2} = {a}^{2} + {b}^{2} \\ {h}^{2} = {(h - 22)}^{2} + {1010}^{2} \\ {h}^{2} = {h}^{2} - 44h + 484 + 1020100$
The h^2 terms cancel out to = 0
$0 = - 44h + 484 + 1020100 \\ 44h = 1020584 \\ 44h \div 44 = 1020584 \div 44 \\ h = 23195.1 \: feet$

Simplify the problem: Sin theta Sec Theta

kherson [118]

Answer:

$\tan \theta$

Step-by-step explanation:

We have to simplify the following expression as given by

$\sin \theta \times \sec \theta$

= $\frac{\sin \theta}{\cos \theta}$

= $\tan \theta$ ( Answer )

Because, we know that $\sec \theta =\frac{1}{\cos \theta}$ and $\tan \theta = \frac{\sin \theta}{\cos \theta}$

If we consider $\sin \theta = \frac{Perpendicular}{Hypotenuse}$ and $\sec \theta = \frac{Hypotenuse}{Base}$ ,

then $\sin \theta \times \sec \theta = \frac{Perpendicular}{Hypotenuse}\times \frac{Hypotenuse}{Base} = \frac{Perpendicular}{Base}= \tan \theta$

The measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees

<h3>Angle of elevation and depression</h3>

From the question given, we have the following parameters

Base of the building = 7feet

Height of the building = 18 feet

Required

angle of elevation

Using the SOH CAH TOA identity

tanФ = opp/adj

tanФ = 18/7

Ф = 68.73 degrees

Hence the measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
