Express the following quantities as ordinary decimal numbers: (step by step please)
jenyasd209 [6]

Answer:

a. 0.0000009 m

b. 6,130, 000, 000

c. 100,000 light years

d. 0.00001 mm

e. 0.0000010 kg

Step-by-step explanation:

Here, we want to come from the standard form to the decimal form

In doing this, we consider the power of 10 attached

If negative, we count leftwards, if positive, we count right-wards

The number of times we count is the power of 10 attached. The count means we are moving the decimal point

For numbers with out visible decimal point, it is at the back of the most right-ward number

Thus, we have these as;

a. 9 * 10^-7

= 0.0000009 m

b. 6.130 * 10^9

= 6,130, 000, 000

c. 1 * 10^5

= 100,000 light years

d. 1 * 10^-5 mm

= 0.00001 mm

e. 10^-7

= 0.0000010 kg

Given circle E with diameter CD and
irina1246 [14]

The Pythagoras is the sum of the square of two sides equal to the square of the longest side. Then the value of AC is 24 units.

<h3>What is a circle?</h3>

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given circle E with diameter CD and radius EA. AB is tangent to E at A.

If AD = 10 and CD = 26.

Then the value of AC will be

We know that the tangent and radius make 90 degrees. Then the triangle is a right-angle triangle.

Then the AC is given by the Pythagoras theorem.

B² = H² - P²

B² = 26² - 10²

B² = 576

 B = 24

More about the circle link is given below.
