Tim’s age is nine more than his sister, Jill. Twice his age added to twice Jill’s age is 330.

Answers

Answer 1

Answer:

jill age is 78 and tim's age is 87

Step-by-step explanation:

let jill age be x then, tim's age is 9+x

by the question,

2(9+x) + 2x = 330

or,18 + 2x + 2x = 330

or,4x = 330-18

or, x = 312÷4

x = 78

9+x= 9+78=87

If the perimeter of this triangle is 15 centimeters, what is the value of n?
5n - 6
n
2n + 1
Express your answer as a decimal number.

Answers

Answer:

25/14

Step-by-step explanation:

The value of n that makes up the triangle of perimeter 15 centimeters is 2.5

How to determine the value of n?

The side lengths of the triangle are given as:

5n - 6, n and 2n + 1

The perimeter is given as:

P = 15

The perimeter is the sum of the side lengths.

So, we have:

5n - 6 + n + 2n + 1 = 15

Collect like terms

5n + n + 2n = 15 + 6 - 1

Evaluate the like terms

8n = 20

Divide both sides by 8

n = 2.5

Hence, the value of n that makes up the triangle is 2.5

This repayment will ultimately reduce her monthly bank account balance

Step-by-step explanation:

This repayment will ultimately reduce her monthly bank account balance. That is because the steady monthly income that Emma would normally receive to her bank account will be taken out of her account and sent to her sister's account. This will continue to occur for 13 months until Emma pays back the $312 that she borrowed from her sister. Once the 13 months are over and her debt is paid, her monthly bank balance will return to normal and begin increasing as her income payments get deposited.

Andy has three planks of wood. Two planks are each 1.5 m long. One plank is 2.5m long. What is the total length of all the three planks?

Answers

Given:

Two planks are each 1.5 m long.

One plank is 2.5m long.

To find:

The total length of all the three planks.

Solution:

Two planks are each 1.5 m long. So,

First plank = 1.5 m

Second plank = 1.5 m

One plank is 2.5m long. So,

Third plank = 2.5 m

Now, the total length of all the three planks is

[tex]\text{Total length}=\text{First plank + Second plank + Third plank}[/tex]

[tex]\text{Total length}=1.5+1.5+2.5[/tex]

[tex]\text{Total length}=5.5[/tex]

Therefore, the total length of all the three planks is 5.5 m.

Step-by-step explanation:

In order to find the value of x that makes m || n, we need to note something.

When two parallel lines are cut by a transversal, their angle measures will be the same.

Therefore, in order for m and n to be parallel, their two angles listed must be equivalent.

So, we can set these expression equal to each other and solve for x.

Answers

Answer:

s = 9 cm

p = 8s

p = 72 cm

Step-by-step explanation:

s = p ÷ 8

Where,

s = length of a side

p = perimeter of a regular octagon

find s when p = 72 cm

s = p ÷ 8

= 72 cm ÷ 8

= 9 cm

s = 9 cm

Formula for p in terms of a

s = p ÷ 8

Equivalent to

s = p/8

Cross product

s * 8 = p

p = 8s

Find p when s = 9 cm

p = 8s

p = 8 * 9 cm

= 72 cm

p = 72 cm

After 6 months you have the same account balance as your friend and you have saved 280$. Write a linear equation that represents your account balance.

Answers

Answer:

y = 20x + 280

Step-by-step explanation:

The linear equation that represent your account balance is as follows:

Your friend

y = 25(6) + 250

= 400

And,

You

400 = m(6) + 280

6m = 400 - 280

6m = 120

m = 20

Now the equation of the account balance is

y = 20x + 280

Hence, the linear equation that represent your account balance is y = 20x + 280

Romantic writers rejected the logical style of writers from the age of reason and instead focused on individual experiences, thoughts, and emotions. Romantic literature used lofty, expressive language to highlight a particular mood and message. What do you think these techniques offered to romantic writers that previous styles did not? Consider the romantic literature you have read. Do you think these techniques and styles were effective for the themes and subjects being addressed? Why or why not?

Answers

Answer:

Step-by-step explanation:

Romantic writers have the advantage of writing what they feel not just what they made up. Romantic writers can make a book sad, scary, and happy. Whereas fictional books almost always end up perfect for the main character. I do think that the techniques and styles were effective for the themes and subjects being addressed because they flow into the subject. Using an absolute sob story for a romantic book could be passed off as a hit if you use the right techniques. So, yes.

Scarce informationE. A different way to informF. Negative characteristics1____________The Vikings have left many traces of their settlement which are still visible today. Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place-names and language shows the lasting effect which the Viking settlements had in the British Isles, and DNA analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settled. All of this provides valuable information, but the only reason that we have an idea of the 'Vikings' as a people is their appearance in the written sources.2___________Unfortunately, the value of the written evidence is limited. Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the Viking Age is regarded as part of prehistory because there are practically no contemporary written sources. Even in western Europe, the Viking Age is often seen as part of the 'Dark Ages', from which comparatively few historical records have survived.3__________Surviving accounts of Viking activity were almost exclusively written by churchmen. These include monastic chronicles, such as the Anglo-Saxon Chronicle and similar Frankish and Irish Annals, which outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters of Alcuin, and Wulfstan's famous 'Sermon of the Wolf', both of which chose to interpret the Viking raids as God's punishment on the Anglo-Saxons for their sins. Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources show Christian rulers behaving equally unpleasantly, but without being condemned on religious grounds.4_________One of the reasons that we have so few records from the Viking Age is that the Vikings did not become familiar with the Roman alphabet (the alphabet we use today) until they adopted Christianity. However, they did have another form of lettering, known as runes. Runes were normally carved, rather than written, and were therefore mostly used for fairly short inscriptions. It is unknown how many people could read runes in the Viking Age. Runic inscriptions on pieces of wood from Bergen in Norway show that runes were used for all sorts of everyday purposes later in the Middle Ages, but no comparable evidence has survived from the Viking Age, and it is likely that few people were literate in runes. However, the fact that some Vikings were able to carve their names on their possessions suggests that the use of runes wasn't uncommon.5____________Most of the surviving runes are found on large memorial stones. Very often they only have the name of the person in whose memory the stone was carved, and the names of those responsible for having it made. Sometimes the name of the rune-carver was also given. Occasionally the inscriptions describe the achievements of the person commemorated, and refer to historical events in which they were involved. For this reason, runic inscriptions are a valuable source for Viking history. However, because they are so brief, they never give a very full picture, and often raise as many questions as they answer.
