A new sports car would be an example of:
A need
A want
Scarcity
A consumer

Answers

A new sports car would be an example of a want.

In economical terms, what is a consumer want?

want is anything that is desired. It is claimed that everyone has a limitless number of desires but only a limited number of resources are available to us. As a result, individuals cannot have everything they desire and must seek out the most cost-effective options.

A consumer's wants often represent preferred preferences for particular solutions to meet a requirement. As a result, individuals frequently desire certain items, brands, or services that meet their demands in a specific way.

A want is anything that will enhance your living experience and level of happiness. In economic terms, wants may be described as an individual's insatiable desire to own items or services that provide fulfillment.

Therefore, we can conclude that owning a new sports car would be an example of a want.

1) Find the area of the shape below. Round your answer to the nearest tenth 16 cm​

Answers

Answer:

151.3 cm²

Explanation:

The shape is composed of a semicircle and a rectangle

Area of the shape = area of the semicircle + area of the rectangle

Area of the shape = ½(πr²) + L*W

r = ½(16 - 6) = ½(10) = 5 cm

L = 16 cm

W = 7 cm

Plug in the values

Area of the shape = ½(π*5²) + 16*7

Area = 39.27 + 112

Area = 151.3 cm² (nearest tenth)

Periglacial landscapes are difficult places to build human structures because the structures will sink without special construction techniques during the months when the frozen ground water thaws.

a. True
b. False

Answers

Answer:

False.

Explanation:

Periglacial landscapes are not difficult places to build human structures because these landscapes are located in the cold climates not on the glaciers  surface. The main difference between Periglacial and glacial landscapes is that Periglacial are located on the rocky surface of earth having cold climate while on the other hand, glacial landscapes are located on glaciers where the surface is made of ice not rock so we can say that Periglacial landscapes are not difficult places to build human structures.

a rock takes off from earth an altitude of 1,140 km in 95 seconds.what was the rocket's average speed,in kilometers per second (km/s)​

Answers

Answer:

the rocket average speed is 12 kilometers per second

Explanation:

Given that

The distance is 1140 km

And, the time is 95 seconds

We need to determine the average speed in kilometers per second (km/s)

So as we know that

Speed = distance ÷ time

= 1,140 km ÷ 95 seconds

= 12 kilometers per second

hence, the rocket average speed is 12 kilometers per second

Which geologic structure will most likely take the longest time to form?

1. A fault
2. A sinkhole
3. A river meander
3. A mountain range

Answers

Answer: 4. A Mountain Range

Explanation:

Mountain ranges are formed as a result of compression forces pulling tectonic plates together and forcing them to collide. Upon collision, the affected areas will have no place to go but up and soo will form a mountain range.

The movements of these plates can be quite slow such that mountain ranges take between thousands to hundreds of thousands of years to form. Mt. Everest for instance was formed as a result of such collisions and it increases by only 2 cm a year.
