Write the expanded form of the decimal 0.082¯ using powers of 10

Mathematics

Softa [21]3 years ago

Answer:

0.082 = 8.2× 10^-2

Step-by-step explanation:

Given the decimal number 0.082, the expanded form using the power of 10 can be gotten by writing the decimal number in standard format(writing as a multiple of 10).

To do that we will shift the decimal point to the front up to the front of digit 8. This shows that the decimal point will be shifted 2times to the front. Since of is shifted 2times to the front, our power of 10 will be -2.

0.082 = 8.2× 10^-2

This gives the required answer.

Note that, the power of 10 is positive when decimals are shifted to the back and negative when shifted to the front(in this case).

Investment: Suppose you receive a gift of $1,000 and decide to open a CD (certificate of
Nina [5.8K]

Answer: 4 years after the original investment, it is approximately $1,093.

Step-by-step explanation:

Hi, to answer this question we have to apply the simple interest formula:  

I = p x r x t

Where:  

I = interest

P = Principal Amount  

r = Interest Rate (decimal form)  

t= years

Replacing with the values given  

I = 1000x (2.25/100) x t

  • It will triple in approximately 3 years. FALSE

I = 1000x (2.25/100) x 3 =67.5

1000+67.5 = 1067.5

  • It will no longer grow after several years: False, it will grow because it has a growth rate.

  • 4 years after the original investment, it is approximately $1,093. TRUE

I = 1000x (2.25/100) x 4 =90

1000+90 = $1090

  • It will double in approximately 10 years.

I = 1000x (2.25/100) x 10 =225

1000+90 = $1225

Feel free to ask for more if needed or if you did not understand something.

A species of phytoplankton measures about 2 × 10−6 in. A grain of sand measures about 1 × 10−4 in. About how many times longer i
Gennadij [26K]

Answer:

B. 50 times greater

Step-by-step explanation:

Given;

size of phytoplankton = 2 × 10⁻⁶ in

size of sand grain = 1 × 10⁻⁴ in

Determine how many times longer the grain of sand is than the phytoplankton.

Divide the sand size by the phytoplankton size, to find out how much greater the sand is.

This can be done by equating it as follows;

2 × 10⁻⁶ (y)  = 1 × 10⁻⁴

y = \frac{1*10^{-4}}{2*10^{-6}} \\\\y = 50

Therefore, the grain of sand is 50 times greater than the phytoplankton

B. 50 times greater

Calculate the surface area of the closed half-cylinder. all measurements are in cm<br>​
AVprozaik [17]

Answer:

2656.31 cm^{2}

Step-by-step explanation:

To calculate the surface area, we need to find the area of all the faces, and add them together.

The faces of the cylinder are: the rectangular base, the curved top, and the two semicircles on the side.

Rectangular base:

A = length x width

A = 29.3 x 16.2

A = 474.66

Two semicircles:

A = \pi x radius^{2} (I'm using the formula for a circle, because the two semicircles are identical, so together they form a circle)

radius = 29.3/2 = 14.65

A = \pi x 14.65^{2}

A = 674.256 (rounded to 3 decimal places)

Curved top:

The curved top, when flattened out, becomes a rectangle with a length of 16.2. The width is equal to half the circumference of the circle formed by the two semicircles.

To find the width, use the circumference (C) formula.

C = \pi x diameter

diameter = 29.3

C = \pi x 29.3

C = 93.049 (rounded to 3 DP)

Area (of curved top) = length x width

A = 16.2 x 93.049

A = 1507.394 (rounded to 3 DP)

Surface Area

SA = 474.66 + 674.256 + 1507.394

SA = 2656.31 cm^{2}
