Find the value of x so that the ratios 8 : x and 12 : 18 are equivalent.

Answers

Answer:

Step-by-step explanation:

12:18=2:3 multiply by four to get 8 as the first term

8:12

8:x

so x is 12.

*this could be wrong so check my work

Answer:

x = 12

Explanation:

8 : x

12 : 18

to find the value of x, we need to convert 12 into 8. since they both have a common factor of 4, we can divide 12 by 3 to get 4, and then multiply it by 2 to get 8. in numerical terms, this is:

12 ÷ 3 = 4

4 × 2 = 8

now, we can do the same for 18.

18 ÷ 3 = 6

6 × 2 = 12

thus, 12 : 18 is equivalent to 8 : 12. x = 12.

River C is 400 miles longer than River D. If the sum of their lengths is 5560 miles, what is the length of each river?

Answers

Answer:

River D - 2580 miles

River C - 2980 miles

Step-by-step explanation:

Let the length of River D be represented with x

length of river C = 400 + x

total length of both rivers = 5560

x + 400 + x = 5560

2x + 400 = 5560

collect like terms

2x = 5560 - 400

2x = 5160

divide both sides of the equation by 2

x = 5160 / 2

x = 2580

length of river c = 400 + 2580 = 2980

Answers

Answer:

309.8 mm

Step-by-step explanation:

17.6 x 17.6= 309.76

309.76 rounded is 309.8

Answer:

309.8

Step-by-step explanation:

The formula for area of square is one of its sides times another (or its side squared).

So if one of the side is 17.6, it would be 17.6^2 which is 309.76.

You then round one decimal place and get 309.8

find the surface area of the figure below

Answers

Answer:

Step-by-step explanation:

square= 16

triangle= 12

12*4 = 48+16 = 64

Answer:

64 m²

Step-by-step explanation:

Hello There!

The surface area is the total area of the figure

So in order to find the area we need to find the area of each shape

For the square:

the square has a length of 4 so we can simply find the area by squaring it

4 * 4 = 16

so the area of the square is 16 square meters

Now we need to find the area of the triangles

The formula for area of a triangle is

[tex]A=\frac{bh}{2}[/tex]

where b = base and h = height

The triangles dimensions are:

base - 4m

height - 6m

having found these dimensions we plug them in into the formula

[tex]A=\frac{4*6}{2} \\4*6=24\\\frac{24}{2} =12[/tex]

so the area of one of the triangles is 12 square meters

We want to find the total area of all of the triangles

To do so we multiply the area of one triangle by 4 (because there are four triangles)

12 * 4 = 48

So the total area of the four triangles is 48 square meters

Finally we add the two areas

48 + 16 = 64

so we can conclude that the total surface area of the pyramid is 64 m²

Write a rule for the nth term of the geometric sequence:
a3=54, a6=1458

Answers

Answer:

tn = -1350 + 468n

Step-by-step explanation:

First, we need to find the difference.

1458 - 54 / 6 - 3

= 468

Now we need to find the first term.

t3 = t1 + (n - 1) (d)

54 = t1 + (3 - 1)(468)

54 = t1 + (2)(468)

54 = t1 + 936

-882 = t1

The rule is:

tn = -882 + (n-1) (468)

tn = -882 + 468n - 468

tn = -1350 + 468n

The fundamental problem with universal health care is how to pay for it. Most would argue that a universal healthcare system is a great idea in theory, but in actuality, no one has figured out a reasonable proposal for where the money should come from. Economists claim that more than 2 trillion dollars are spent on health care each year. Thats over $6,000 per person. Part of the argument for universal health care is that businesses and individuals are having trouble affording health care because the current costs are already extremely high. With a universal system, everyone would be able to go to the doctor. Therefore, it would be reasonable to assume that universal health care would cause the already ponderous cost of health care in the United States to increase even more. One proposal would take money from other areas and move it to pay for health care. This means that departments such as education or public defense would receive less money, which would have a negative impact on the country. The most likely proposal is that taxpayers would have to pay into a large pool from which everyone would draw for their health needs. This would create several problems. First, it would raise taxes for everyone. It would also mean, fundamentally, that many people who choose a healthy lifestyle would be required to pay the same amount as people who choose to live an unhealthy lifestyle, which hardly seems equitable.

November 4, 1851 Dear Brother, When I came into Charleston day before yesterday, I learned that you are anxious to sell the land where you live and move to Missouri. I have been thinking of this ever since, and cannot but think such a notion is utterly foolish. What can you do in Missouri better than here? Is the land any richer? Can you there, any more than here, raise corn and wheat and oats without work? Will anybody there, any more than here, do your work for you? If you intend to go to work, there is no better place than right where you are; if you do not intend to go to work, you cannot get along anywhere. Squirming and crawling about from place to place can do no good. You have raised no crop this year; and what you really want is to sell the land, get the money, and spend it. Part with the land you have, and, my life upon it, you will never after own a spot big enough to bury you will get for the land you will spend in moving to Missouri, and the other half you will eat, drink, and wear out, and no foot of land will be bought. Now, I feel it my duty to have no hand in such a piece of foolery. I feel that it is so even on your own account, and particularly on mother's account. The eastern forty acres I intend to keep for mother while she lives; if you will not cultivate it, it will rent for enough to support herat least, it will rent for something. Her dower in the other two forties she can let you have, and no thanks to me. Now, do not misunderstand this letter; do not write it in any unkindness. I write it in order, if possible, to get you to face the truth, which truth is, you are destitute because you have idled away all your time. Your thousand pretences for not getting along better are all nonsense; they deceive nobody but yourself. Go to work is the only cure for your case. A word to mother.
