A contractor has installed a silt fence around an area that is semi-circular and level to prevent soil from the construction site entering nearby streams. The diameter of the semi-circle is 1200 feet. How many linear feet of fence does the contractor need to use to enclose the area?

Answer:

The answer is or

Step-by-step explanation:

we know that

The circumference of a circle is equal to

where

D is the diameter of the circle

In this problem, to calculate how many linear feet are needed, find the perimeter of a semicircle

so

we have

substitute the value

3085

[(1200xpí)/2]+1200

[(1200xpí)/2]+1200

Find two rational numbers within 1/8.

A rational number is a number that can be expressed as a fraction or whole number, so two rational numbers that are a factor / within 1/8 is 1/2 and 1/4. 1/2 * 1/4 = 1/8. Like this answer? Give it a Brainiest answer if so.

your bike lock has 4 digits numbered 0-9. Find the total number of possible combinations for the lock.

Answer:

10,000

Step-by-step explanation:

With a bike lock, you can usually use the same number more than one... you can have them the same (7777) if you want.

So, you have 10 possibilities for the first digit, 10 again for the second digit, 10 for the third digit... and also 10 for the last digit. So...

10 * 10 * 10 * 10 = 10,000

These combinations range from 0000 to 9999

Diego drops his camera as he climbs a hill and it falls to the ground 256 feet below the distance D that the camera falls in T seconds is given by the equation D=16t2 how long does it take The Camera to hit the ground

Given that Diego drops his camera as he climbs a hill and it falls to the ground 256 feet below the distance D.

to solve the time it hit the ground, use the given equation

D = 16t^2

t^2 = d /16

t = sqrt( d / 16)

t = sqrt( 256 / 16)

t = 4 second

after 4 s the diego's camera will hit the ground

to solve the time it hit the ground, use the given equation

D = 16t^2

t^2 = d /16

t = sqrt( d / 16)

t = sqrt( 256 / 16)

t = 4 second

after 4 s the diego's camera will hit the ground

A triangle has a base of 10 inches and a height of 12 inches. What is the area of the triangle?

22 in²

40 in²

60 in²

120 in²

To find the area is base × hight

10 in × 12 in= 120 in2

10 in × 12 in= 120 in2

A boat costs $11850 and decreases in value by 10% per year how much will the boat be worth after 8 years

Answer:

Step-by-step explanation:

Keep subtracting 10 %

U will get 5101 approx.

Answer: the boatf will be worth $5101 after 8 years.

A decrease of 10% is equivalent to multiplying the current value by 0.9.

Every year the value gets multiplied so we get an exponential function in years:

value after y years =

value after 8 years =

PLZ HURRY!!BFF FOREVER AND WILL GIVE BRAINLIEST!!!!:)))) Look around you; think about when you enter a new city, or what you drive past on the highway. Give at least 5 examples of Geometry, in real life, that you see on a regular basis and how it pertains to Geometry.

The 5 examples of Geometry in real life, which is seen regularly, are as follows:

- Road construction, alignment, and cross-sections
- Building construction, profile, and decorative shapes
- Power lines and their masts
- Natural topology
- Other public infrastructure.

What is Geometry?

Geometry is a branch of mathematics with a focus on the measurement and relationship of shapes, lines, angles, surfaces, solids, and points. This branch of mathematics deals with spatial relationships and the measurement of dimensions.

Thus, the examples of Geometry in real life can be seen around us every second.
