Answer:

The answer to your question is 20 times

Step-by-step explanation:

Data

United States' population = 3 x 10⁸

Kazakhstan's population = 1.5 x 10⁷

Process

1.- To solve this problem, just divide the United States' population by  Kazakhstan's population.

                      3 x 10⁸ / 1.5 x 10⁷ = 20

2.- Conclusion

The population of the United States is 20 times greater than Kazakhstan's population.

Stephen & Richard share a lottery win of £2950 in the ratio 2 : 3. Stephen then shares his part between himself, his wife &a
horsena [70]

Answer:

Stephen's wife got £354 more than his son.

Step-by-step explanation:

Given:

Amount of Lottery = £2950

Now Given:

Stephen & Richard share a lottery amount in the ratio 2 : 3

Let the common factor between them be 'x'.

So we can say that;

2x+3x=2950\\\\5x = 2950

Dividing both side by 5 we get;

\frac{5x}{5}=\frac{2950}{5}\\\\x = 590

So we can say that;

Stephen share would be = 2x =2\times 590 = \£1180

Now Given:

Stephen then shares his part between himself, his wife & their son in the ratio 3 : 5 : 2.

Let the common factor between them be 'y'.

So we can say that;

3y+5y+2y=1180\\\\10y=1180

Dividing both side by 10 we get;

\frac{10y}{10}=\frac{1180}{10}\\\\y=118

So Stephen's wife share = 5y = 5\times 118= \£590

And Stephen's son share = 2y=2\times118 =\£236

Now we need to find how much more her wife got then her son.

To find how much more her wife got than her son we will subtract Stephen's son share from Stephen's wife share.

framing in equation form we get;

Amount more her wife got than her son = 590-236 = \£354

Hence Stephen's wife got £354 more than his son.

tigry1 [53]

Answer:

b=40.01\ units

Step-by-step explanation:

we know that

Applying the law of sines

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

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

we have

a=25\ units

A=32.5\°

Find the measure of angle B

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

so

A+B+C=180\°

substitute the given values

32.5\°+B+26.8\°=180\°

B=180\°-59.3\°=120.7\°

Find the length side b

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

substitute the values

b=\frac{25}{sin(32.5\°)}(sin(120.7\°))

b=40.01\ units
