The volume of a can (right circular cylinder) is 10 cubic feet. the curved surface area is the area of the side. write the curved surface area s as a function of the radius r. s =

Answers

The volume formula of a cylinder is given as:

V = π r^2 h

So plugging in the value of the volume:

10 ft^3 = π r^2 h

h = 10 / (π r^2) ---> eqtn 1

The formula for the surface area of cylinder is:

s = 2 π r h + 2 π r^2

plugging in eqtn 1:

s = 2 π r [10 / (π r^2)] + 2 π r^2

s = (20 / r) + 2 π r^2 (ANSWER)

Round 28,573 to the nearest thousand

Answers

29,000 is the answer rounded to the nearest thousand.

28,573 rounded to the nearest thousand

first, find the number in the thousands place....it is 8...now look at the number directly to the right of it....
** if that number is 5 or above, u would round that 8 up to a 9
** if that number is 4 or below, u would leave the 8 alone

so the number directly to the right of 8 is a 5...that means we have to round that 8 up to a 9

making ur answer : 29,000 <== because 28,573 is closer to 29,000 then it is to 28,000

The correlation coefficient r between the size of a lake in square miles, x, and the yearly number of registered boaters, y, is 0.743. What percent of the variation in the number of yearly boaters can be explained by differences in lake sizes?
74.3%
55.2%
44.8%
37.2%

Answers

Actually variation is simply equivalent to the square of the correlation coefficient r. So we can say that:

variation = r^2

So given an r value of 0.743, so the variation is:

variation = 0.743^2

variation = 0.552

Answer:

55.2%

Under which condition does a country with a small GDP have a large per capita income?

Answers

the concept here is that if a country has a small population, then the per capita income would be large. by dividing the total income by the total population giving you the per capita income.

-hope this helps

GDP, or gross domestic product, is how many goods and services a country or realm produces over an interval, usually a year.

the per capita part, means, the average per person, so you grab the GDP, say 5 trillion, and divide it evenly among all inhabitants, so a per-capita figure is really just GDP/population.

now, you can have a population like Germany with 80 million with a GDP of say hmmm 8000 million for simplification, the per-capita is then 8000/80 or $100 per person.

now, you could have another population like say Japan, and let's just say is less people... hmmm 20 million, with a GDP of say 4000 million.

then the per-capita in that example for Japan will be 4000/20, which is $200 per-capita, notice, the Japan's example has a higher per-capita, though the GDP is smaller to the example of Germany, that's because the Japanese population is also smaller.

sidenote: per-capita figures are often very misleading, since economies do not grow that linearly.

How many integers less than 1000 have no factors (other than 1) in common with 1000?

Answers

168 numbers beginning with the
2, 3, 7, 11,13 and ending with the 983, 991 and 997

There are 999 integers less than 1000. Immediately, we can eliminate all of the even numbers among those, since we know they share the factor 2 with 1000. This gets rid of 499 integers, leaving us with 500 odd integers. To make our next elimination, we'll have to take a look at 1000 again.

1000's prime factorization is 2³ · 5³, which means that our final filter on the remaining integers should be to eliminate every integer divisible by 5. Any whole number ending in a 0 or a 5 is divisible by 5, but since we've eliminated all even numbers from our list, we've split the amount of those divisible numbers in half. It may be a bit hard to visualize this elimination, so let's figure out how many integers would get eliminated in a bit of a simpler setting first:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

Usually we'd be eliminating 4 numbers from this sequence, but in a sequence with all the even numbers eliminated:

1 3 5 7 9 11 13 15 19

We only eliminate half that amoung, or 2.

Here, we'd usually be eliminating 100 of the numbers from our list of 500 (or 1/5 of the list, since we eliminate a number every 5 integers), but here, we're only eliminating half of that amount, or 50. This leaves us with 500 - 50 = 450 integers with no factors in common with 1000.

Note: We also sometimes refer to numbers with this kind of relationship as coprime or relatively prime.

The lengths of the sides of a triangle are represented by 3 consecutive even integers. if the perimeter of the triangle is 72 feet, find the lengths of its sides

If two opposite sides of a square are increased by 15 meters and the other sides are decreased by 5 meters, the area of the rectangle that is formed is 69 square meters. find the area of the original square.

Answers

Let y= original side So A = LW 60 = (y+15)(y-13) (y+15)(y-13) = 60 y^2 + 2y - 195 = 60 y^2 + 2y- 195 - 60 = 0 y = -17 or y= 15 Toss out the negative solution to get y= 15 as the only solution. So the square has a side length of 15 meters. The area of this square is 15^2 = 15*15 = 225 square meters.

what is 4kx+10kx=7 solve for x

Answers

[tex]4kx+10kx=7[/tex]

Final answer:

To solve the equation 4kx+10kx=7 for x, combine like terms to get 14kx = 7, then isolate x by dividing both sides by 14k, resulting in x = 1 / (2k).

Explanation:

The question asks: what is 4kx+10kx=7 solve for x. To solve this equation for x, we first need to combine like terms. We combine 4kx and 10kx to get 14kx. The equation then becomes 14kx = 7. To isolate x, we divide both sides of the equation by 14k. This gives us x = 7 / (14k). It simplifies further to x = 1 / (2k). Therefore, the solution to the equation is x = 1 / (2k).

A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the coins is $1.40. How many nickels and how many dimes are in the jar?

Answers

n = number of nickels
d = number of dimes

n+d = 20
0.05n + 0.10d =1.40

-0.05n - 0.05d = -1
0.05n + 0.10d = 1.40

0.05d = 0.40
d = 8

n = 20-8=12

There are 12 nickels and 8 dimes

The value of x is 61 after using the concept of vertically opposite angles option (A) 61 is correct.

What are vertically opposite angles?

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

The angles are shown in the picture.

As we know, from the definition of vertically opposite angles, the angles when two lines intersect each other and at the intersecting point.

The first angle = 2x + 24

The second angle = 146

Equating both the angles:

2x + 24 = 146

2x = 146 - 24

2x = 122

x = 122/2

x = 61

Thus, the value of x is 61 after using the concept of vertically opposite angles option (A) 61 is correct.

25% of what number is 9
can you explain how you got your answer and show your answer too.
Thank You

Answers

Keep in mind the the word "percent" translates to "for each 100." 25% can be read as "25 for each 100," which has the fractional representation [tex] \frac{25}{100} [/tex] and the decimal representation 0.25. All of these representations are just different ways of writing the same value.

Note too that the fraction [tex] \frac{25}{100} [/tex] can be reduced to [tex] \frac{1}{4} [/tex], so what the question is really asking is: 1/4 of what number is 9?

Well, if we know that 1/4 of the number is 9, we can easily find how large the whole number is by finding all 4/4 of it (the whole number), or 4 x 9, which multiplies out to 36.
