Convert 0.345634563456…to a rational number in the form of ab, where b≠0.

alexandr1967 [171]

A standard trick for finding the rational form of a repeated decimal:

$x=0.34563456\ldots=0.\overline{3456}$

Multiply by an appropriate power of 10 to move one "cycle" of the repeated pattern to the left side of the decimal point:

$\implies10^4x=3456.34563456\ldots=3456.\overline{3456}$

Now subtract $x$ from this number and we lose the fractional part:

$\implies10^4x-x=9999x=3456$

And from here you can solve for $x$ .

$\implies x=\dfrac{3456}{9999}=\dfrac{384}{1111}$

Answer:

Here are some formulas and some info to get you started:

Step-by-step explanation:

Parallelogram:

Area = Base · Height

Triangle:

Area = 1/2 · Base · Height

Know that the height is the vertical dotted line. Also know that the horizontal dotted line attached to the base is not actually part of the base.

If you need any more help let me know, and good luck!

An isosceles triangle has angle measure 40, 40, and 100. The side across from the 100 angle is 10 inches long. How long are the

Alinara [238K]

Answer:

The other two sides of given isosceles triangle are 6.53 inches long.

Step-by-step explanation:

in the figure below,

ABC is an isosceles triangle has angle measure 40, 40, and 100. The side across from the 100 angle is 10 inches long an let this side be b

Let the other two be a inches long .

We have to find the measure of side AB.

Sine rule is an equation relating the lengths of the sides of a triangle to the sines of its angles. According to the law,

For a triangle Let B stands for the angle at B. Let C stand for the

angle at C and A for angle A. Also, let b = AC, a = BC and c = CB = a.

$\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$ ............(1)

Using sine rule,

Putting values in (1),

$\frac{a}{\sin 40}=\frac{10}{\sin 100}=\frac{a}{\sin 40}$

Considering first two ratios,

$\frac{a}{\sin 40}=\frac{10}{\sin 100}$

${a}=\frac{10 \times \sin 40}{\sin 100}$

${a}=6.52704 \Rightarrow a=6.53$ (approx)

Since, the triangle is isosceles so, other two sides are equal.

Thus, other sides are 6.53 inches long.
