Step-by-step explanation:

a. we do first the multiplication 3*4=12

-9-12=-21

b. you do parenthesis first

(-2)^3=-8  

(-8)*(-4)= +32

now we have (32)-3=29

c. as you see in the red square we do multiplication first, than division

3*2=6

(-18)/6=-3

Answer:

(E) 3(sq rt 2)

Step-by-step explanation:

the figure is a square so all four sides are equal and has 90 degree corners.

the diagonal has the value of 6 so:

6^2=s^2+s^2

36=2s^2

s^2=18  or sq rt 18 which would be 3(sq rt 2)

Hal earns n dollars per hour. Next month he
will receive a 296 raise in pay per hour. The
expression n +0.02n is one way to represent
Hal's pay per hour after the raise Write an
equivalent simplified expression that will
represent his pay per hour after the raise.

Answers

Answer:

[tex]Total = 1.02n[/tex]

Step-by-step explanation:

Given

[tex]Earnings = n[/tex]

[tex]Raise = 2\%[/tex] --- not 296

[tex]Total = n + 0.02n[/tex]

Required

Simplify the expression for total earning

The total amount is derived from:

[tex]Total = Earnings + Raise * Earnings[/tex]

[tex]Total = n + 2\% * n[/tex]

Express percentage as decimal

[tex]Total = n + 0.02 * n[/tex]

Now, we can solve further:

[tex]Total = n + 0.02n[/tex]

[tex]Total = 1.02n[/tex]

Hence, the simplified expression is 1.02n

22=-48+a

add 48 to both sides

70=a

At a local fitness​ center, members pay a ​$10 membership fee and ​$4 for each aerobics class. Nonmembers pay ​$6 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the​ same?

Answers

Answer:

5 classes

Step-by-step explanation:

Let x represent the number of aerobics classes

Create an equation that sets the member and nonmember prices equal to each other, then solve for x:

4x + 10 = 6x

10 = 2x

5 = x

So, after 5 aerobics classes, the costs will be the same.

Answer:

Please look down below

Step-by-step explanation:

∠1 + 69 + 47 = 180 (because straight line)

∠1 = 180 - 116

∠1 = 64

∠2 + ∠1 + 63 = 180 (because triangle)

∠2 + 64 + 63 = 180

∠2 = 180 - 127

∠2 = 53

∠3 + ∠1 = 180 (because straight line)

∠3 + 64 = 180

∠3 = 116

∠5 = ∠4 (given)

∠5 + ∠4 + ∠3 = 180

Denote ∠5 and ∠4 as x, so 2x

2x + ∠3 = 180

2x + 116 = 180

2x = 64

x = 32

∠5 = 32, ∠4 = 32

∠6 + 136 = 180 (because straight line)

∠6 = 44

∠7 + ∠6 + 47 = 180 (because triangle)

∠7 + 44 + 47 = 180

∠7 = 180 - 91

∠7 = 89

x^4 – 256

Answers

Answer:

(x²+16)(X+4)(x-4)

Step-by-step explanation:

x⁴ can be written as (x²)²

256 can be written as (16)²

by identity. a²-b²= (a+b)(a-b) :

(x²+16)(x²-16)

x²-16 can be written as (x)²- 4²

by identity. a²-b²= (a+b)(a-b) :

(X+4)(x-4)

Therefore, the factors altogether would be

(x²+16)(x+4)(x-4)

Find the solution to the equation. URGENT

Answers

Answer:

x + 6 + x + 6 + x + 6 + x + 6 + x + 6 x + 6 + x + 6 + x + 6 = 120

aka 8(6 + x) = 120

48 + 8x = 120

you want to get 8x on one side so you will subtract 48 on both sides - whatever you do to obe side you must do on the other side.

8x = 72

now you want the x by its self so to undo multiplication you need to divide, and divide on both sides.

In the year 2005, there were 100 rabbits in a particular region. Since then, the population has increased by 3.4% per year. Write an expression that represents the rabbit population in the year 2025, and solve it.

Answers

Answer:

Step-by-step explanation:

Your answer

Ok, lets do it systematically.

2005– 100 rabbits

3.4 % per year increasement.

So every year it increase 0.034 *100 = 3.4 per year

Total 2025-2005= 20 years

So expression is : 0.034*100*year(20)

Answer is : 3.4*20 = 68. So, in 2025, total rabbits will be 168

A quality-control engineer samples 100 items manufactured by a certain process, and finds that 15 of them are defective. True or False:
a) The probability that an item produced by this process is defective is 0.15.
b) The probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.

Answers

Answer: b) The probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.

Step-by-step explanation:

Given that:

Number of samples = 100

Number of defective samples = 15

Proportion =number defective samples / total samples

P = 15 / 100 = 0.15

Hence, the probability that an item produces is defective is 0.15.

However, due to sampling Variations, the probability will be corrected for these variations. Hence, probability that an item produced by this process is defective is likely to be close to 0.15, but not exactly equal to 0.15.

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 Exercise 4.3.
