Answer \frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}
step-by-step explanation:
here x represents the height of the pole,
and, the height of the shadow of the pole is 12 feet.
also, the angle of elevation from the top of the pole is 40°,
therefore,
by the low of sine,
\frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}
which is the required equation for finding the value of x,
\frac{x}{sin40^{\circ}}= \frac{12}{sin60^{\circ}}
x= 12\times \frac{sin40^{\circ}}{sin60^{\circ}}
x= 12\times 0.74222719896
x= 8.90672638762\approx 8.967
Answer:
=215
Explanation:
5x-10 subsitute 45 for X
=5(45)-10
simplify
=225-10
=215

Explain and discuss the relationship between Prestige, Power and Income when examining Social Stratification.
Answer:
Social Stratification
She's from the wrong side of the tracks. He was born with a silver spoon in his mouth. This degree is my ticket to the world!
What do these phrases mean? They are referencing social standing or social stratification. Social stratification is a method by which societies categorize and rank members in a hierarchy.
Stratification is a key concept in sociology. Early societies didn't rank members. As societies evolved, they began to classify their members. Some categories, like landowners, received promotions. Others, like wage earners, seemed to be demoted.
Today, all societies use social stratification, though some countries are more stratified than others. The systems and the beliefs behind those systems are deep-rooted. Stratification systems impose inequalities that persist for generations.
Social Stratification in the U.S.
For example, in the United States, it's fairly easy to detect the 'haves' from the 'have-nots.' Today's Rockefellers still enjoy the wealth and status gained by family members in the late 19th century. On the other hand, some families of former slaves still struggle.
The U.S. stratification system is based on socioeconomic status or SES. SES is a categorization formula that considers a person's income, education, and occupation. Our society places a higher value on:
Wealth
Longer periods of education
Occupations that require advanced degrees
The sum of these factors is used to determine a person's general social class. Social class is important because the U.S. uses a class system of stratification. A class system is a stratification system in which a person's social status is based on achievement. For the most part, that means Americans can choose or earn social status. They are not locked into a particular status from birth. Class systems allow social mobility, which is movement up or down the social hierarchy. This is a unique characteristic of the class system. This equality of opportunity is often referred to as the 'American Dream.'
For example, the Rockefeller family owes their fortune to John D. Rockefeller. John was the son of a traveling peddler who'd been run out of town and accused of crimes. He was forced to drop out of high school. He set his mind to business and executed a series of timely oil deals. By age 38, his company controlled 90% of the oil refined in the U.S.

How have human systems and political systems shaped Central America and the Caribbean?
Answer: This quesiton can cover many topics, but if you want the most basic ones it could be transportation, culture, and the form of government
Explanation:
Many of the countries are still developing, and because of this, their governments are corrupt as heeeeeeckk. Presidents and government officials tend to steal money from its people a lot, through everything. This is because of very weak law enforcement and the limiting of powers. This causes for the economy and education in the country to go down. This also causes more poverty, which means less people go to school and get careers. This is one of the big reasons why I appreciate the free education in the U.S., we are very privileged and we should be grateful for the things we have that others wish to obtain. :(
The Panama Canal improved transportation a thousand times better. People from California or Asia had to go around South America through boat, and this took about 12 - 14 months. When the canal was built, the time decreased to about 3 months (which is a lottt). It also decreased the deaths from starvation or hitting icebergs at the south.
The cultures across the countries are very different due to different conquerors during the Colonization Era back in the 17th century. Spanish, British, French, Dutch, etc. conquered many parts of land, so that’s why Mexico speaks Spanish while its neighboring country, Belize, speak English. The culture diversity is very high in the Americas.

a blender has a power of 400 watts and a total of 4800 joules of energy is transferred when the blender is in use calculate the time that the blender is used for.
Answer:
12 seconds
Explanation:
In physics, power can be defined as a rate of energy transfer. In other words it shows how much energy was transtered over a period of time.
There is a simple equation that connects all of this:
P = E/t,
P is power
E is energy
t is time
Here, we are given power of a blender of P = 400 W, and total energy transfer of E = 4800 J. So:
400W = 4800J / t
t = 4800/400
t = 12s
