How Do I Use Brainly Math For Solving Stuff Like This And How Do I Show My Evidence On Paper?

Answers

Answer 1

Answer:

a) 3

b) 1/3

Step-by-step explanation:

I've never used Brainly math before, but I can help you out with the work for these problems.

Part A

3(x + 1) - x = 15

3x + 3 - x = 15

4x + 3 = 15

4x = 12

x = 3

Part B

5(x + 2) - 2x = 11

5x + 10 - 2x = 11

3x + 10 = 11

3x = 1

x = 1/3

Express q(x)=12x^5+40x^4-32x^3 in the form described in the Linear Factorization Theorem. List each zero and its multiplicity

Answers

To Express q(x)=12x^5+40x^4-32x^3 in the form described in the Linear Factorization Theorem. The zero is 0, 2/3, -4 and the multiplicity is: 3, 1, 1.

Factorization

q(x)=12x^5+40x^4-32x³

q(x)=4x³ (3x²+10x-8)

q(x)=4x³(3x²+12x-2x-8)

q(x)=4x³ [(3x (x+4)-2 (x+4)]

q(x)=4x³ (3x-2) (x+4)

When:

q(x)=0; x1=0; x2=2/3; x3=-4

Hence:

When:

x=0 the multiplicity is 3

x=2/3 the multiplicity is 1

x=-4 the multiplicity is 1

Therefore the zero is 0, 2/3, -4 and the multiplicity is: 3, 1, 1.

Choose which statements are true:

I. Every parallelogram is a rhombus.

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Answers

Answer:

II. Every rhombus is a parallelogram.

III. Every quadrilateral has 4 sides.

Step-by-step explanation:

        Not all parallelograms are rhombuses because a rhombus needs to have equal sides, but a parallelogram does not.

        The definition of a rhombus is "a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides" so all rhombuses are parallelograms.

        The definition of a quadrilateral is having four sides, so all quadrilaterals will have four sides.

Lacey worked 40 hr. at $18.75 per hour. Find her pay using P = RH.

Answers

Answer:

750

Step-by-step explanation:

I multiplied the hours she worked by the amount of payment per hour.

Answer:

$750

Step-by-step explanation:

Since Lacey worked 40 hours with the condition that each hours, Lacey will be paid for $18.75, because they worked 40 hours, therefore:

[tex]\displaystyle \large{P = 18.75+18.75+18.75+...+18.75}[/tex]

From above, you add from first hour pay to 40th hour pay. However, that’d take quite a long time to evaluate:

[tex]\displaystyle \large{\sum_{H=1}^{40} 18.75 = 18.75 \cdot 40}[/tex]

Then evaluate 18.75 * 40 and therefore the solution is $750

For usage of formula:

P = RH for P = pay, H = hour and R = rate (pay per hour)

So if you use the formula, you’d still end up with P = 18.75*40 which is $750

You have a bag of gummy worms with 5 green, 3 blue, 6 red, and 2 orange. Which expression represents the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?​

Answers

Answer:

[tex]\frac{1}{8}[/tex] I think

Step-by-step explanation:

you have a bag witha a total of 16 gummy worms right? 6 out of 16 of them are red, 5 out of 16 are green.

so you pull out a red one and eat it. the probabilty of you doing that is [tex]\frac{6}{16}[/tex] . keep it in mind that you ate a gummy worm.after enjoying that gummy worm you decide to take another one, but this time, it's green. you know you just ate one right, but you did not replace it now did you? what that means is out of the 16 gummies you had, you are now left with 15 (because you ate one).now you are left with 15 gummy worms. you take a green one out of the packet. the probabilty of you doing that is [tex]\frac{5}{15}[/tex].

now that you've got your probabilities all sorted, now it's time to use some basic probability principles. if you ever come across a probability question with the word and, you need to know automatically that you are multiplying. if you ever come across the word or, you are adding. it's always gonna be like this.

so when you multiply your two probabilities, you get the answer [tex]\frac{1}{8}[/tex]

whenever you're dealing with probability, make sure you're aware of things that are being taken. check whether they're being replaced or not. the way I attempted at working it out is how the other probability questions involving replacements are solved, no matter what it is.

so, there's what's called standard form in maths. this is where you're given a crazy-long chain of digits and are made to shorten that long number. the great thing about this kind of notation is that it makes reading large quantites easier (like super easy)

when dealing with standard form, the unit before the comma must always be from numbers one to nine, always!!!the digits before the comma must never be zero or anything above 9.99999... never!!! after placing your comma all you have to do is count the number of digits (or in this case, zeros) that number of digits after the comma then becomes the power your 10 is being raised to.it is crucial for you to remember that 10, otherwise your number won't be in it's standard form

Giving Brainliest!Read the article Skara Brae:Skara Brae is one of the oldest historical sites in Europe, and it stayed hidden for more than 4,000 years. The ancient village of Skara Brae was discovered on the main island of Orkney, in Scotland. A massive storm in 1850 removed the sand that had covered it for thousands of years, exposing the remains of a small village.Skara Brae is a collection of eight round, stone houses that still have their stone furnishings and even some of the belongings of the inhabitants. The contents can tell us a great deal about how people lived in what is called the Neolithic era, or the last period of the Stone Age. Seven of the eight houses appear to have been family homes, with beds, dressers, fireplaces, and even simple toilets. The eighth house may have been a community workshop. It shows evidence of tool-making and the use of a large fire pit.How was Skara Brae built, and what, eventually, happened to it? Let's journey back in time through the evidence archaeologists have put together to understand the story of Skara Brae.The small, stone village was built sometime around 3100 BCE. The first villagers dug down into an existing midden heap, or trash heap, to build the foundations of their homes. The garbage helped to insulate and protect the homes. They built their round huts with stones found locally, sticking each piece together with a paste made from ground-up waste and dung.After the houses were built, the villagers furnished their homes with stone beds, one on each side of the door, a stone dresser, and a fireplace, or hearth. The hearth kept the home warm and allowed the inhabitants to cook their food.The people of Skara Brae then farmed the surrounding lands, with evidence suggesting that they grew barley and other grains. They kept cows and pigs, and they fished in the ocean for a good part of their diet.As the number of people grew, the village expanded. Covered tunnels and alleyways were built to connect all the homes. This would have protected people traveling from one house to another from cold winter weather. Because of the connections between the houses and the shared workspace, archaeologists believe that Skara Brae was a close-knit community.The people made many things, including pottery, stone tools, and bone jewelry. Curiously, no evidence of weaponry was ever found, leading archaeologists to believe that Skara Brae was a peaceful place.Skara Brae was inhabited for approximately six hundred years, at which point, it was abandoned. Many theories exist about what happened to the people of Skara Brae. One of the most popular theories is that a terrible storm, similar to the one that would uncover the remains of the village in 1850, struck and drove the people from their homes. This is supported by the fact that so many possessions, including valuables like jewelry, were left behind.Which supporting detail supports the main idea that Skara Brae was an ancient village? (A) Because of the connections between the houses and the shared workspace, archaeologists believe that Skara Brae was a close-knit community. (B) Seven of the eight houses appear to have been family homes, with beds, dressers, fireplaces, and even simple toilets. (C) The contents can tell us a great deal about how people lived in what is called the Neolithic era, or the last period of the Stone Age.(d) The first villagers dug down into an existing midden heap, or trash heap, to build the foundations of their homes.Good luck!
