The answers are as follows:

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7 - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

Concept: Standard notation is a way of writing a number so it is easier to read. It is often used for very large or very small numbers.

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

In the given questions,

3000- standard notation

4.2*10 raised to 4 - scientific notation

1.05 × 10 raised to power –7 - scientific notation

0.0013 - standard notation

6,500,000 - standard notation

6.2 × 10 raised to power 19 - scientific notation

PLEASE HELP

Answer:

The ratio between the radii of circles A and B is equal to $\frac{4}{3}$ and this ratio represent the scale factor

Step-by-step explanation:

Let

x -----> the radius of circle A

y -----> the radius of circle B

z -----> the ratio between the radii of circles A and B

$z=\frac{x}{y}$

we know that

$x=4\ units$ ----> radius of circle A

$y=3\ units$ ----> radius of circle B

Find the ratio z

$z=\frac{4}{3}$

The ratio represent the scale factor of the dilation of radius of circle B to obtain the radius of circle A

Circles A and B are similar, because A translation, followed by a dilation will map one circle onto the other

Answer:

a) x = 36%

b) c = 52.2

c) z =38%

d) y = 16%

Step-by-step explanation:

a) Given that b is x% more than a and c is y% more than b.

Therefore, $a(1 + \frac{x}{100}) = b$ ....... (1)

Now, if a = 25.25 and b = 34.34, then from equation (1) we get,

$25.25 (1 + \frac{x}{100}) = 34.34$

⇒ x = 36% (Answer)

b) Given that b is x% more than a and c is y% more than b.

So, $a(1 + \frac{x}{100}) = b$ ......... (2)

and, $b(1 + \frac{y}{100}) = c$ ......... (3)

If a = 36 and x = 25%, then from equation (2) we gat,

$b = 36(1 + \frac{25}{100})$

⇒ b = 45

Now, y = 16%, then from equation (3) we get

$c = 45(1 + \frac{16}{100})$

⇒ c = 52.2 (Answer)

c) Given that b is x% more than a and c is y% more than b. And c is z% more than a.

Now, if x = 15% and y = 20%, then

$b = a(1 + \frac{15}{100}) = 1.15a$ and $c = b(1 + \frac{20}{100}) = 1.2b$

⇒ c = 1.2(1.15a) = 1.38a

Therefore, $a(1 + \frac{z}{100}) = c = 1.38a$

⇒ z =38% (Answer)

d) Given that b is x% more than a and c is y% more than b. And c is z% more than a.

If x = 25% and z = 45%, then

$b = a(1 + \frac{25}{100}) = 1.25a$ and

$c = b(1 + \frac{y}{100}) = 1.25a(1 + \frac{y}{100})$ ........... (4) and

$c = a(1 + \frac{45}{100}) = 1.45a$ ......... (5)

Now, from equations (4) and (5) we get

$1.25a(1 + \frac{y}{100}) = 1.45a$

⇒ y = 16% (Answer)
