So you find the common denominator which is 12.Then you convert both fractions to 12ths. 3/4=9/12 and 1/3 = 4/12.9/12 plus 4/12=13/12.
13/12 is an improper fraction so you convert into a mixed number which is 1 and 1/12.

1 1/12= answer

hope this helps!!!

First covert them to fractions with the same denominator so you can compare them (9/12 and 4/12), then subtract the numerators, and not the denominators (9/12-4/12), then whatever you get is the answer (5/12). If you can, simplify.

The maximum load of a horizontal beam that is supported at both ends varies jointly as the width and the height and inversely as
dezoksy [38]

Answer:

360kg

Explanation:

Here, we want to get the maximum load supported

From the first part of the question, we have it that:

The maximum load g, varies jointly with the width w and the height h, and inversely as the length l between the supports

Mathematically, we have that as:

g\text{ = k }\times\frac{wh}{l}

where k is the proportionality constant

Now, let us get the value of k

We substitute the first set of values as follows:

\begin{gathered} 360\text{ = }\frac{k\times0.1\times0.06}{6} \\  \\ k\text{ = 360,000 }\frac{kg}{m} \end{gathered}

Now, using this value of k, we want to get the value of g

Mathematically, we have that as:

g\text{ = }\frac{360,000\times0.2\times0.08}{16}\text{ = 360 }kg

Find side x , give your answer 1 decimal place <br>​
Vladimir [108]

<u>Given</u>:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

\frac{sin \ A}{a}=\frac{sin \ B}{b}

Substituting the values, we have;

\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}

Simplifying, we get;

\frac{0.988}{x}=\frac{0.643}{7}

Cross multiplying, we have;

0.988 \times 7=0.643 x

     6.916=0.643x

       10.8=x

Thus, the length of the side x is 10.8 cm.
