6) What is 13% of 33.39?
icang [17]

Answer:

1. We assume, that the number 33.39 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 33.39 is 100%, so we can write it down as 33.39=100%.

4. We know, that x is 13% of the output value, so we can write it down as x=13%.

5. Now we have two simple equations:

1) 33.39=100%

2) x=13%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

33.39/x=100%/13%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 13% of 33.39

33.39/x=100/13

(33.39/x)*x=(100/13)*x       - we multiply both sides of the equation by x

33.39=7.6923076923077*x       - we divide both sides of the equation by (7.6923076923077) to get x

33.39/7.6923076923077=x

4.3407=x

x=4.3407

now we have:

13% of 33.39=4.3407

What is the length of Ac? Round to the nearest tenth.
I am Lyosha [343]

Given:

The figure of a right angle triangle.

To find:

The length of the line segment AC.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Opposite}{Adjacent}

In the given right triangle ABC,

\tan (A)=\dfrac{BC}{AC}

\tan (55^\circ)=\dfrac{BC}{AC}

\tan (55^\circ)=\dfrac{15}{AC}

AC=\dfrac{15}{\tan (55^\circ)}

On further simplification, we get

AC=\dfrac{15}{1.428148}

AC=10.503113

AC\approx 10.5

The length of side AC is equal to 10.5 m .

Therefore, the correct option is A.
