Answer:

0.2% of 50 = $0.1$

Step-by-step explanation:

0.2% of 50

We have to find 0.2% of 50

$50*0.2*\frac{1}{100}$

$50*\frac{2}{10}* \frac{1}{100}$

= $\frac{5*2}{100}$

= $\frac{10}{100}\\\\ \frac{1}{10}\\\\0.1$

The 0.2% of 50 is 0.1

How many times can 0.1 fit into 100?

ANTONII [103]

Answer:

1000 times

Step-by-step explanation:

To find out how many times 0.1 can fit into 100, we can just divide 100 by 0.1.

But, we first find out how many times can 1 fit into 100.

No. of times 1 fit into 100 = 100 / 1 = 100 times

Now we know 1 is 10 times of 0.1, so we multiply the above by 10,

so 100 * 10 = 1000 times.

Therefore 0.1 can fit into 100 a 1000 times.

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.
