You have 2 shapes, a rectangle and a half circle.

Area of rectangle = 3 x 8 = 24

Area of a half circle = 1/2 x pi x r^2

Area of half circle = 1/2 x 3.14 x 4^2

Area of half circle = 25.12

Total area = 24 + 25.12 = 49.12 square units

The Miller family spent a total of $317.05 hosting a party for their grandparents' 50th wedding anniversary. They spent $48.55 on decorations and $8.95 per person on food.

Which equation could be used to find the number of people (x) at the anniversary party?

A.
48.55 + 8.95x = 317.05
B.
48.55x + 8.95 = 317.05
C.
48.55x − 8.95 = 317.05
D.
48.55 − 8.95x = 317.05

Hi his figure is made up of unit cubes, each with a volume of 1 cubic unit.
What is the volume of the figure?
( photo is attached)
(Will give brainliest if you help)

Answers

Answer:

D. 100 cubic units

Step-by-step explanation:

There are 10 cubes in each layer (count at the top) and 10 layers (from top to bottom) in total. Multiply these to get volume.

10 x 10 =100

Answer:

B. 60 cubic units

Step-by-step explanation:

Formulas for a cube:

The volume of a cube:

V = a3

The surface area of a cube:

the area of each face (a x a) times 6 faces

S = 6a2

Face diagonal of a cube:

By the Pythagorean theorem, we know that

f2 = a2 + a2

Then f2 = 2a2

solving for f we get

f = a√2

Diagonal of the solid cube:

Again, by the Pythagorean theorem, we know that

d2 = a2 + f2

substituting f into this equation we get

d2 = a2 + (a√2)2 = a2 + 2a2 = 3a2

solving for d we get

d = a√3

The average weekly salary of two employees is $5250. One makes $500 more than the other. Find their salaries.

Answers

Answer: thier salaries are $5000 and $5500

Step-by-step explanation:

Let the average weekly salary of one employee be =x

And that of the other employee be = x+500

Such that if thier average of their salaries= $5250

So, their total salary=  $5250 x 2=10,500

The  equation  to solve each employee salary becomes

x+x+500=10,500

2x+500=10,500

2x=10,500-500

2x=10,000

x=10,000 /2

x= first employee salary =$5000

second employee =   x+500 =$5500

A local cable TV/Internet/phone provider charges new customers $129 for all three services, per month, for the first year under their "3 for 129" promotion. Joanne normally
pays $74 for her monthly home phone service, $59 for Internet service, and $69 for cable television
a. What are her percent savings if she switches to the "3 for 1299 plan? Round to the nearest percent.
b. If, after the first year, the flat fee for all three services is $139, what are her percent savings? Round to the nearest percent.

Answers

Answer:

Step-by-step explanation:

Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202

a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73

Percentage of saving = [tex]\frac{73}{202}*100[/tex] = 36.13 = 36%

b) Amount saved after the first year = 202 - 139 = $ 63

Percentage of saving = [tex]\frac{63}{202}*100[/tex] = 31.18 = 31%

Read the information about the countries of SW Asia and then write a 1 paragraph response using RACES that answers: Compare and contrast citizen rights of Isreal, Turkey, and Saudi Arabia.IsraelFor Israelis and visitors who choose religious practice of any faith or denomination (religious group an individual chooses), freedom of worship is assured as one of Israels basic tenets (beliefs). Those who prefer freedom from religion are equally protected. All Israeli citizens enjoy the full civil, legal and political rights guaranteed by a democratic (free) society. Some examples include the right to elect and to be elected, the right to free education, the freedom of expression and association, and many more.TurkeyThere is an ongoing debate in the country on the right to life, torture, freedom of expression as well as freedoms of religion, assembly and association. Turkey still keeps laws which are seen as undemocratic (not free) or authoritarian (strict obedience), such as prohibiting minorities (Kurds the country's largest minority) to get a primary education in their mother tongue. In March 2017, the United Nations accused the Turkish government of "massive destruction, killings and numerous other serious human rights violations" against the ethnic Kurdish minority. Some independent newspapers and websites face tremendous political pressure and are targeted for prosecution if they say anything negative about the government. Academics (university/schools) who openly discuss sensitive or politically charged subjects have found themselves targeted by the government.Saudi ArabiaSaudi Arabias absolute monarchy restricts almost all political rights and civil liberties. Women and religious minorities face extensive discrimination in law and in practice. Political Rights: Saudi Arabias king is chosen by his predecessor (the person who rules after a king) from among male descendants of the countrys founder, though the choice must be approved by a council of senior princes. The king rules for life. Political parties are forbidden, and political dissent (go against) is effectively criminalized (found guilty/imprisoned). Opposition (to go against) movements are banned. Noncitizens, who make up roughly a third (33%) of the population in Saudi Arabia, have no political rights, and citizenship can only be directly transmitted by a citizen father whose marriage is recognized by the state. The government controls domestic media content; print and satellite-television coverage. Journalists can be imprisoned. In October 2018, one of the countrys most prominent journalists, Jamal Khashoggi, was murdered by Saudi agents inside the Saudi consulate in Istanbul. Khashoggi, who had been critical of the government under Mohammed bin Salman, had been working in the United States as a columnist at the Washington Post. Saudi officials blamed rogue intelligence agents, but according to a UN special rapporteur, the evidence suggested that the crown prince was involved. In December 2019, a Saudi court sentenced five men to death for their role in the killing, and three others received prison sentences, but the most senior officials under investigation were acquitted due to a supposed lack of evidence. Mohammed bin Salman was never officially investigated. The government prohibits the public practice of any religion other than Islam. Academic freedom is restricted, and informers monitor classrooms. Freedom of assembly (to come together as a group) is prohibited. The government has imposed harsh punishments, including the death penalty on those who lead or participate in public protests. Torture by police and prison officials is common. In March 2019, international media published leaked prison medical records indicating that a number of political prisoners were suffering from cuts, bruises, burns, and malnutrition. Human rights groups had reported in late 2018 that detained (held in custody) womens rights activists were given electric shocks, whipped, and beaten.
