Answer:

5,339,479

Step-by-step explanation:

The populations in millions of the different countries can be represented by the equations ...

c = 5.2(1.025^t)

d = 5.2(1.001^t)

We want to find d when c = 10. Solving for t when c=10, we have ...

10 = 5.2(1.025^t)

10/5.2 = 1.025^t

log(10/5.2) = t×log(1.025)

t = log(10/5.2)/log(1.025)

Then the value of d for that value of t is ...

d = 5.2(1.001^(log(10/5.2)/log(1.025)) ≈ 5.3394789

The population of Denmark is about 5,339,479 when the population of Chad is 10 million.

_____

If we round the number of years to 26.5 before computing the population of Denmark, we get 5,339,571 -- about 92 more people. Ordinarily, one would not round intermediate results.

What is 7/1 dividend by 14/3

katrin2010 [14]

7/1 x 3/14 = 21/14 = 3/2 = 1 1/2

The answer is 1 1/12 or 1.5, but I recommend the fraction way since the problem was in fractions!

Sammy has x flavors of candies with which to make goody bags for Frank's birthday party. Sammy tosses out y flavors, because he

harkovskaia [24]

Answer:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$

Step-by-step explanation:

Total flavors Sammy initially had = x

Number of flavors Sammy throw away = y

After throwing away y flavors, the number of flavors Sammy will be left with = x - y

He needs to make 10-flavor bags from these (x - y) flavors. In order words he needs to chose 10 flavors for each bag from(x - y) flavors. The order of selection is not important here, so this is a problem of combinations. Also since we have to make selections or small groups, this also indicates that we have to use combinations.

So we need to make combinations of 10 flavors from a total of (x - y) flavors. This can be represented as $^{(x-y)}C_{10}$

The formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!(n-r)!}$

Using the values in this formula, we get:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$

(9x−2.25)=(1.6+9x)<br><br> help

mel-nik [20]

Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.

A set of equations is shown above. Which method eliminates one of the variables? A) Multiply equation A by -1/3 and add the resu

Paraphin [41]

Answer:

Step-by-step explanation:

Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick. Let's actually solve the problem!

Equation A: (5/3)x + 3y = 12

Equation B: 4x - 3y = 8

---------------------------

(5/3 + 12/3)x = 15 Note how this has eliminated the variable

(17/3)x = 15 y.

x = (3/17)(15)
