Algebra:
a(3b-1)=2b+2
Solve for b

Answers

Answer:

b = [tex]\frac{3ab - a - 2}{2}[/tex]

Step-by-step explanation:

We have an algebraic expression and are asked to solve for b.

a(3b - 1) = 2b + 2

To solve we need to isolate b :

Distribute :

(a(3b) - a(1)) = 2b + 2

3ab - a = 2b + 2

2b + 2 = 3ab - a

Subtract 2 from both sides :

2b = 3ab - a - 2

Divide 2 from both sides :

b = [tex]\frac{3ab - a - 2}{2}[/tex]

Answer:

b = 2+a/ 3a-2

Required:

Find x

SOLUTION:

√x(√x - 2) + 2(√x - 2) = 0 (distributive property)

x - 2√x + 2√x - 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

Answers

Answer:

B) 81°

Step-by-step explanation:

∡1 ≅ ∡5 because they are corresponding angles

∡5 ≅ ∡7 because they are vertical angles

therefore, ∡1 ≅ ∡7

since the angles are equal we can create the following equation:

3x + 18 = 2x + 39

x + 18 = 39

x = 21

∡7 = 2(21) + 39

∡7 = 42 + 39

∡7 = 81

The density of ethyl acetate at 25 degrees is 0.902 g/ml. How many pounds would 133 ounces weigh

Answers

Answer:

[tex]8.3125[/tex]pounds

Step-by-step explanation:

We are given that

Density of ethyl acetate at 25 degrees =[tex]0.902g/ml[/tex]

We have to find the number of pounds in 133 ounces weigh.

To find the number of pounds in 133 ounces we will use unitary method

By using unitary method

We know that

1 ounce=0.0625 pounds

133 ounce=[tex]133\times 0.0625[/tex]pounds

133 ounce=[tex]8.3125[/tex]pounds

Hence,8.3125 pounds would 133 ounces weigh.

How do you use Trigonometric Ratios to solve Real-world problems

Answers

9514 1404 393

Explanation:

Obviously, the way you use trig ratios will depend on the problem. The problems you see in algebra and trig courses are a good sampling of the kinds of problems you run across in the real world. Some of them include ...

finding height or widths based on a measure and an angle (SOH CAH TOA)

finding areas based on side lengths and an angle (area formula)

finding unknown sides or angles of a triangle (law of sines/cosines)

finding bearing and/or distance (spherical trig relations, law of cosines)

As with solving problems of any kind, you choose the appropriate formula(s), fill in the known values, and solve for the unknown values. Sometimes a real-world problem will require solution of intermediate problems before the answer to the original question is found.

Answer:

explanation:

Step-by-step explanation:

1: Well, of course since you’re going below sea level, the number is gonna be negative. so you’re gonna take -240 + -12. which is -252. but then you’re gonna take the -252 and add POSITIVE 80. so now if you take -252 + 80 you get -172. so the diver is 172 meters below the surface

2: -127.1

3: The highest temperature is POSITIVE 110°F. But since the lowest one is NEGATIVE 34°F, you’re gonna want to take 110 - 110 to get 0, then go 34 less than 0. so 110 + 34 is 144. so the difference is 144°

Find the slope of the line y=-5/7x-1

Answers

Answer:

-5/7

Step-by-step explanation:

With the equation y = mx + b, m is the slope of the line.

Since the equation is y = -5/7x - 1, m is -5/7

So, the slope of the line is -5/7

Answer:

m = -5/7

slope = -5/7

The expression is

Answers

Answer:

290d + 245

Step-by-step explanation:

Hello! So what you do first is make two equations, then combine them.

For the food booths, the equation would be 15(4d) + 150

For the game booths, the equation would be 23(10d) + 95

Now simplify them.

Food booths: 60d + 150

Game booths: 230d + 95

Next, we combine the two equations to get one equation.

60d + 150 + 230d +95

Simplify even more...

290d + 245

This is going to be your equation. I don't know the number of days the fair went so I can't go any futher on this question. Hope this helps though!

A cylinder has a base radius of 9m and a height of 14m. What is its volume in cubic m, to the nearest tenths place?

Please help

Answers

Answer:

3562.6 m³

Step-by-step explanation:

In this question, we have to find the volume of a cylinder.

The formula to find the volume of a cylinder is V = πr²h

Plug in your values and solve.

Solve:

V = π(9)²(14)

V = π(81)(14)

V = π(1,134)

V = 3562.566069

Round to the nearest tenths place.

V = 3562.6

Don't forget that the units for volume is already cubed, or to the power of 3.

Your final answer would be 3562.6 m³

Write your answers in simplest form. what is the answerHelp me please Directions: Read the passage, and answer the question that follows.The Black DeathA The growing cities of the Middle Ages could be exciting places. However, many were dark, unsafe, and unhealthy. Streets were narrow, crooked, and filthy. There were no streetlights or police. Many people did not go out alone at night for fear of robbers. If people did go out, they often took servants along with them for protection and to carry lanterns or torches to light the way. Waste was dumped into open gutters. All in all, conditions were disgusting. This caused diseases to spread quickly through the crowded cities.B Beginning in 1347, one such disease, a terrible plague, swept through Europe. The disease was called the Black Death because of the darkened color of its victims faces after they died. The plague began in Asia and spread along busy trade routes. Trading ships carried the disease west to the Mediterranean. From the Mediterranean ports, the disease spread throughout most of Europe. Rats on the ships carried the disease. Fleas from the rats spread the disease to people.C Once people became infected, the disease could be spread from person to person. People became infected as they came in contact with the sick. According to Jean de Venette, a friar who lived at the time, young people were more likely to die than old people. Those who got sick lasted only two or three days and then died suddenly. This happened in such great numbers that often those who lived could not keep up with burying the dead. The friar wrote, Someone who was healthy one day could be dead and buried the next. . . . A healthy person who visited the sick hardly ever escaped death.D No one knows the exact number of plague deaths in Europe. Some guess that about 25 million people died in Europe from 1347 to 1351. This was about one third of the entire population. The death rate varied from place to place. Towns seemed to be harder hit than the countryside. Some entire villages and towns were wiped out. The plague affected the rich as well as the poor. Even the great and powerful, including royalty, were struck down. Throughout Europe, populations were devastated by, as the Welsh called it, death coming into our midst like black smoke.E The Black Death greatly affected Europe. Relations between the upper classes and lower classes changed. Workers, now in short supply, demanded higher wages. In several European countries, peasants staged uprisings. There were emotional effects as well. In some areas, the theme of death appeared in poetry, sculpture, and painting. Peoples faith was shaken. The church lost some of its power and importance. The Black Death took a greater toll on human life than any war or illness before that time. It was perhaps the greatest tragedy in all of European history.It is most likely that disease hit towns harder than the countryside because the towns a.had no policeb.had more ratsc.were not lighted d.were more crowdedPlease select the best answer from the choices providedABCD Biarritz Corp. is growing quickly.

Justinians AccomplishmentsAt the core of Justinians goals as a leader was reestablishing the greatness of the Roman empire. He sought to do this in three ways. First, he engaged in several battles to recapture (take over) the land lost to barbarian invaders during the decline of the Roman empire. Second, rebuilding the capital city of Constantinople after the riots and fires of 532 CE. Third, and most memorable is the drafting of Justinians Code. Justinian set up a commission to collect and revise all of the Roman laws. In 529 CE, Justinian published the first set of laws known as the Body of Civil Law of Justinians Code. The code included laws on marriage, slavery, property ownership, womens rights, and criminal justice. Also included was an outline of the law and a collection of Justinians own new laws. Justinian used the law to unify his empire under his control and provide a sense of stability for his people. Justinians Code did not only have an effect of the Byzantine empire.
