. A honeybee leaves the hive, traveling at a speed of 4 mph and returns 1 hour later. What was the distance traveled and the displacement of the honeybee in miles?

Answers

Answer:

4miles

Step-by-step explanation:

Step one:

given

speed, v= 4mph

time taken t=1 hour

The velocity is defined and the rate of change of displacement

Required:

Distance traveled

we know that the expression relating distance, velocity and time is

velocity= distance/time

distance= velocity* time

substitute we have

Distance=4*1

Distance= 4miles

The distance traveled and the displacement of the honeybee in miles  4miles

Ariana borrows $200 on a 6-year loan.She is charged 5% simple interest per year.How much interest is she charged for 6 years?What is the total amount she has to pay back? PLS HELP

Answers

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $200

Interst rate (r)= 0.05

Time (t)= 6

First, we need to calculate the total interest using the following formula:

I= P*r*t

I= 200*0.05*6

I= $60

Now, the total debt:

Total debt= P +I

Total debt= 200 + 60

Total debt= $260

Angle ABC has a measure of 125° Angle ABC is rotated 75° about point B to create angle A'B'C'. What is the measure, in degrees, of angle A'B'C

Answers

Answer:

m∠A'B'C' is 125°

Step-by-step explanation:

The given parameters are;

The measure of ∠ABC = 125°

The form of transformation applied to ∠ABC = 75° rotation about the point B

Given that a rotation of a geometric figure is a form of rigid transformation, the distance between the coordinates of the points in the preimage are equal to the distance between the coordinates of the points on the image;

Therefore, the angle formed by the ray AB and CB and the angle formed by the ray A'B' and C'B' are equal

From which we have;

m∠ABC = m∠A'B'C' = 125°

2(x-2)-5=3-2x+6​

Answers

Answer:

x=9/2

Step-by-step explanation:

First distribute 2

2x-4-5=3-2x+6

Add the like terms on the left side -4-5=-9

2x-9=3-2x+6

Do this with the right side 3+6=9

2x-9=-2x+9

Add 9 from the left side to the right side

2x=-2x+18

Then add 2x from the right side to the left side

4x=18

Divide 4 from both sides

x=18/4 or 9/2

Answer:

9/2

Step-by-step explanation:

2x-4-5= 3-2x+6  distribute 2 through the parentheses

2x-4-5=9-2x     add the numbers

2x-9=9-2x calculate the difference

2x+2x-9= 9  move variable to left side and change sign

2x+2x= 9+9 move constant to right side and change sign

4x= 18  collect like terms

x=9/2 divide both sides by 4

The national government is divided into three sections:executive, legislative, and judicial. Citizens age 18 and older are allowedto vote for president and the legislative branch. Turkeys government isbased on a constitution that was passed in November 1982. It has beenamended several times since then. In 2017, citizens voted to changethe constitution. One of the changes made the country a presidentialrepublic. Citizens now vote directly for a president who serves as bothhead of government and head of state. Before the change, the head ofgovernment was the prime minister, who was chosen by the presidentfrom among members of parliament.Turkeys government is secular, which means there is a separationbetween religion and government. In Southwest Asia, Turkey is one ofthe few countries that is mainly Muslim but does not use Islamic law.While Turkey has made progress in the rights of its citizens as part of theirefforts to join the European Union, there is still room for improvement.Turkeys citizens do not enjoy complete freedom of speech. It is a crimeto insult the Turkish nation and the president. Unfavorable press coverageof the military, Kurds, or Islam can also lead to arrests.The executive branch of Turkeys government is made up of the president and the cabinet. The president serves as head of state and head of government and is elected by the citizens for a five-year term with a two-term limit. The direct election of the president began in 2017 aftera constitutional amendment. Members of the cabinet are appointed bythe president. Turkeys legislative branch has one house called the Grand NationalAssembly of Turkey. The Assembly has 600 seats. Each seat is directlyelected by the citizens and serves for a five-year term. Turkey is dividedinto 81 provinces. Each province has representatives in the Grand National Assembly.Turkeys judicial branch is made up of the Constitutional Court, theCourt of Cassation, and the Council of State. The Constitutional Courthas 15 members3 appointed by the Grand National Assembly and 12appointed by the president. These judges are appointed for one 12-year,nonrenewable term with mandatory retirement at age 65. The main roleof the Constitutional Court is to make sure laws passed by the GrandNational Assembly are constitutional. The Court of Cassation has about390 judges who serve until retirement at age 65. The main purpose ofthe Court of Cassation is to give a final verdict after decisions made bylower courts are appealed. Finally, the Council of State is organized into15 divisions, each with its own division head and at least five members.These judges are appointed for a four-year term that can be renewed.The main purpose of the Council of State is to give a final ruling in administrative issues.
