Express the following quantities as ordinary decimal numbers: (step by step please)
a. The wavelength of light is 9 x 10^-7 m.

b. The estimated world population for the year 2000 was 6.130 x 10⁹.

c. The diameter of our galaxy, the Milky Way, is 1 x 10⁵ light years.

d. The smallest viruses are 1 x 10^-5 mm in size.

e. The mass of a bee's wing is 10^-7 kg. ​

Answers

Answer 1

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 f(x)=3x^2+9x+k and the remainder when f(x) is divided by x+1 is -14, then what is the value of k?

Answers

Answer:

The value of k is -8.

Step-by-step explanation:

Given;

f(x) = 3x² + 9x + k

factor of the function = x + 1

remainder of the function = -14

let x + 1 = 0

x = -1

f(-1) = 3(-1)² + 9(-1) + k = -14

3(-1)² + 9(-1) + k = -14

3 - 9 + k = -14

-6 + k = -14

k = -14 + 6

k = -8

Therefore, the value of k is -8.

Eva's new bunny weighted 1 7/8 pounds when she first got him 4 weeks ago. Now he weighs 2 1/4 pounds. How much weight has Eva's dog actually gained

Answers

Answer: Eva's dog actually gained 3/8 pounds ( 0.375pounds)

Step-by-step explanation:

Step 1

Given that

old weight = 1 7/8  pounds

New weight = 2 1/4 pounds

weight gained = New weight - Old weight

Step 2

 weight gained = New weight - Old weight

                  2 1/4  pounds - 1 7/8 pounds

      2.25 pounds - 1.875 pounds

         0.375pounds = 3/8 pounds

Suppose Ethan has 28 comic books. If the ratio of comic books with Native superheroes to comic books without Native
superheroes is 1:3, how many comic books have Native superheroes?
a. 6 comic books
b. 7 comic books
c. 4 comic books
d. 5 comic books

Answers

Answer:

7

Step-by-step explanation:

N. comic books : Non N. Comic books=

1:3

Total number of parts= 4

If the total number of parts is 4 then logically , 4 represents 28.

So here we'll write

4 p = 28

I p = 28/4= 7

The native comic books is 1 p.

So we'll write,

1 p = 7 ×1 = 7 comic books
