Answer:

(2\times 10^{-3})\times (4\times 10^4)=4\times 10^1

Step-by-step explanation:

We have been given that a mustard seed has a mass about 0.002 gm. A glass jar contains about  4.3602\times 10^4 seeds. We are asked to find the mass of mustard seeds in the jar.      

First of all, we will convert the mass of mustard seed in scientific notation.

0.002=2\times 10^{-3}

To find the mass of seeds in jar, we will multiply number of seeds by mass of one seed.

\text{Mass of seeds in jar}=2\times 10^{-3}\times 4.3602\times 10^4

Using exponent property a^b\cdot a^c=a^{b+c}, we will get:

\text{Mass of seeds in jar}=2\times 4.3602\times 10^{-3+4}

\text{Mass of seeds in jar}=8.7204\times 10^{1}

Therefore, option C is the correct choice.

Helga [31]

Answer:

option D . 254.34cm^2

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

The options are:

A . 56.52cm^2

B . 141.30cm^2

C . 1,017.36cm^2

D . 254.34cm^2

step 1

Find the diameter of the largest circle

we know that

The diameter of the largest circle is equal to the sum of the diameter of the two inside circles

so

D=6+12=18\ cm

step 2

Find the area of the largest circle

we know that

The area of the circle is given by the formula

A=\pi r^2

we have

r=18/2=9\ cm ----> the radius is half the diameter

assume

\pi=3.14

substitute

A=(3.14)(9^2)=254.34\ cm^2

A small company is creating a new product to sell to buyers. They have estimated that it will cost them $6 to produce each item
miv72 [106K]

Answer:

$347,600

Step-by-step explanation:

There is fixed startup cost of 242,000 no matter how many units they product.

Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:

17,600 * 6 = 105,600

Along with this the fixed startup cost of 242,000, would make total cost:

Total cost = 242,000 + 105,600 = $347,600
