Answer 2

Answer:

-1.6r + 1.8

Step-by-step explanation:

-1.6 (r+2) +5

^ the -1.6 can be distributed to the (r+2) because it's basically multiplying

that becomes --> -1.6r + -3.2 + 5

Now the -3.2 and 5 are like terms so they can be solved together

-> -3.2 + 5 = 1.8

Now, -1.6r and 1.8 are not like terms because 1.8 does not have an r attached to it so you cannot do nothing from there

your answer becomes = -1.6r + 1.8

The fraction 10/5.5 with decimal denominator can be simplified to the lowest term as 20/11 or as a decimal 1.8181 approximately to four decimal place.

How to simplify the fraction with decimal denominator

To simplify the fraction with decimal denominator, first convert the decimal to fraction and then use its reciprocal to multiply the numerator as follows:

5.5 = 55/10

so that the original fraction becomes;

10/5.5 = 10 ÷ 55/10

10/5.5 = 10 × 10/55 {the division become multiplication by multiplying the the numerator with the reciprocal of the denominator}

10/5.5 = 100/55

10/5.5 = 20/11

or

10/5.5 = 1.8181 as a decimal.

Therefore, the fraction with decimal denominator can be simplified to the lowest term as 20/11 or as a decimal 1.8181 approximately to four decimal place.

A snail can crawl at a rate of 6 cm in 0.75 minutes. Which represents the constant rate of change of the snail's crawl?

Answers

Answer:

0.00133m/s

Step-by-step explanation:

Given

distance crawled by the snail = 6cm = 0.06m

Time taken = 0.75minutes = 0.75*60

Time taken = 45secs

Required

constant rate of change of the snail's crawl (speed)

Speed of the snail = distance/time;

Speed of the snail = 0.06/45

Speed of the snail = 0.00133m/s

Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s

A line passes through the points (4,17) and (7,20). Write a linear function rule in terms of x and y
for this line.
The linear function rule is y=?

Answers

Answer:

The linear function rule is [tex]\mathbf{y=x+13}[/tex]

Step-by-step explanation:

A line passes through the points (4,17) and (7,20). Write a linear function rule in terms of x and y

for this line.

The function rule is of form: y=mx+b

Where m is slope and b is y-intercept

Finding slope using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have [tex]x_1=4, y_1=17, x_2=7, y_2=20[/tex]

Putting values and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{20-17}{7-4}\\Slope=\frac{3}{3}\\Slope=1[/tex]

Finding y-intercept b

Using the point (4,17) to find y-intercept b

[tex]y=mx+b\\17=1(4)+b\\17=4+b\\b=17-4\\b=13[/tex]

So, the linear function rule is:

[tex]y=mx+b\\y=1x+13\\\mathbf{y=x+13}[/tex]

The linear function rule is [tex]\mathbf{y=x+13}[/tex]

A line passes through the points (4,17) and (7,20).

The linear function rule is y= 1x+13

Given :

A line passes through the points (4,17) and (7,20).

The linear function is y=mx+b where m is the slope

lets find out slope using formula

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\(4,17) and (7,20)\\m=\frac{20-17}{7-4}=1 \\[/tex]

Slope of the line using the given points is 1

Lets pick any one point (4,17) and use slope to find function rule y

y=mx+b

x is 4  and y is 17  and m=1

[tex]17=1(4)+b\\17=4+b\\17-4=b\\13=b[/tex]

Replace the value of 'b' and write the equation

[tex]y=mx+b\\y=1x+13[/tex]

The linear function rule is y= 1x+13

D: 48 to 41, 48:41, 48/41

Answers

Answer:

D

Step-by-step explanation:

The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking girls to boys the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) always goes on top. So that eliminates C which leaves only answer to be D.

Sally is making 15 individual blueberry cheesecakes. How many pounds of blueberries will be in each cheesecake it 5 and 1/4 pounds of blueberries

Answers

Answer:

.35lbs or 7/20lbs

Step-by-step explanation:

if 5 1/4 lbs of blueberries are being distributed evenly through 15 cheesecakes, you would divide 5 1/4 by 15 to see how many lbs of blueberries would be in each cheesecake, which would make .35 lbs of blueberries per cheesecake, or 7/20 lbs.

The number of pounds of blueberries will be in each cheesecake should be  .35lbs or 7by 20lbs

The calculation is as follows;

When 5 1 by 4 lbs of blueberries are being distributed evenly through 15 cheesecakes,

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. helppIn the relationship below, the position of the circle changes according to theheight of the rectangle.
