Answer:

12989 people

Step-by-step explanation:

f(x)=a(1+r)^x

a= the amount you start with

r=is the rate that it is growing

x= time intervals

12000(1+0.02)^4=12989

Given:

The equation is

[tex]25+x=31[/tex]

25 is subtracted from both sides.

To find:

The missing values for the given blanks.

Solution:

We have,

[tex]25+x=31[/tex]

If 25 is subtracted from both sides, we get

[tex]25+x-25=31-25[/tex]

[tex](25-25)+x=6[/tex]

[tex]0+x=6[/tex]

So, the missing values for the blanks are 0 and 6 respectively.

It is also written as

25   +   x    =   31

-25                 -25

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

 0   +   x    =   6

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

Therefore, the missing values for the blanks are 0 and 6 respectively.

Answer:

1.4

Step-by-step explanation:

Given the expression 2.1/1.5.

This can also be expresses as;

2.1/1.5

= 21/10 ÷ 15/10

= 21/10 × 10/15

= 21/15

= 7/5

= 1.4

Hence the result is 1.4

Answer:

x = 10

Step-by-step explanation:

To isolate the variable (x) you would first write out x - 3 = 7. Now to make x on its own we have to get rid of the -3 so to do that we would add the reciprocal of -3 (or the opposite) which is +3. x - 3 + 3 = 7 + 3 or x = 10.

Answer:

The answer is A^2

Step-by-step explanation:

When you are dividing, You subtract exponents if they have the same base.

The base (variables) are the same. So you subtract the powers.

Which are 5 and -3. You subtract those two powers 5 minus negative -3 which gives you 2.  So it's  a^-2

Sorry for the long explanation I hope you understand it. And if I made it harder to understand the answer sorry oops have a good day and stay safe ;D.

Answer:

(1) [tex](x,y) = (-2,-4)[/tex]

(2) [tex]y = 4x -26[/tex]

(3) [tex]x = 1[/tex]

Step-by-step explanation:

(1):

[tex]2x - y = 0[/tex]

[tex]x + 3y = -14[/tex]

Required: Solve for x and y

Make x the subject in [tex]x + 3y = -14[/tex]

[tex]x = -3y - 14[/tex]

Substitute -3y - 14 for x in the first equation

[tex]2x - y = 0[/tex]

[tex]2(-3y-14) - y = 0[/tex]

Open bracket

[tex]-6y - 28 - y = 0[/tex]

Collect Like Terms

[tex]- y-6y = 28[/tex]

[tex]-7y = 28[/tex]

Divide both sides by -7

[tex]y = -4[/tex]

Substitute -4 for y in [tex]2x - y = 0[/tex]

[tex]2x - (-4) = 0[/tex]

[tex]2x + 4 = 0[/tex]

Collect Like Terms

[tex]2x = -4[/tex]

Divide by 2

[tex]x = -2[/tex]

Hence, the solution is:

[tex](x,y) = (-2,-4)[/tex]

(2):

[tex](x_1,y_1) = (7,2)[/tex] -- points

[tex]m = 4[/tex] --- slope

Required: Determine the line equation

This is calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 4(x - 7) + 2[/tex]

Open bracket

[tex]y = 4x - 28 + 2[/tex]

[tex]y = 4x -26[/tex]

(3)

[tex]4 - 5x + 3 = 4x - 2[/tex]

Required: Solve for x

Collect Like Terms

[tex]- 5x -4x = - 2-3-4[/tex]

[tex]-9x = -9[/tex]

Divide both sides by -9

[tex]x = 1[/tex]

Answer:

Follows are the solution to the given question:

Step-by-step explanation:

They can count the days of the year 1 to 365. The random project consists of drawing a sample of n objects from D where elements are n people's birth in a group but instead, D = {1,....365}. And then there's the issue.

[tex]S=365^n[/tex]

This because the list of future birthdays of n people was its test point; therefore m points will be in the sequence so each point contains 365 distinct outcomes. The probability function P for \Omega is that any event is likely to happen in 365 days.

[tex]P(x)=\frac{1}{365^{n}}[/tex]

if x is between 1 and 365 as well as the occurrence is just all similarly possible

In point i:

That somebody mentions their birthday throughout the party

Guess I was born on day b. Therefore the consequence of "x is in A" is "b is now in the series of x," which is to say, b = bk for some amount k approximately 1 and n.

In point ii:

Any 2 persons share the same birthday at this party". A result x is in B" means which "two of entries in x are same." This means that perhaps the outcome x is in B if or only if bj = bk is in B of two numbers j, and k of 1, of two. , no, n.

In point iii:

Many three students share the same birthday with both the party. The consequence is x at the level of C only when bj = bk = bl at three (different) indices, j, k, l, 1. , no, n.

Answer:

a) - 7 dollars

b) 24.30 dollars

c) - 5 dollars

Step-by-step explanation:

b) 27 / 10%

Divide 27 by 10/100 by multiplying 27 by the reciprocal of 10/100.

27 x 100/10

Multiply 27 and 100 to get 2700.

2700/10

Divide 2700 by 10 to get 270.

270

Divide 270 by 100 to get 2.7

Subtract 27.00 - 2.7 = 24.30

24.30

Answer:

A=18.1, B=72.4, and C=89.5

Step-by-step explanation:

Where A, B and C represent their respective angles:

We are given that:

B=4A

C=5A−1

And since ABC make up a triangle, we know that:

A+B+C=180

Since we have three variables and three equations, we can solve for A, B, and C. To solve for A:

Take the equations B=4A and C=5A−1, and plug B and C into the last equation:

A+B+C=180

A+4A+5A−1=180

10A – 1 + 1 = 180 + 1

10A=181

10 /10 x A = 181/10

             A = 18.1

Then we can plug this value into the first two equations to solve for B and C:

B=4A

B=4(18.1)=72.4

C=5A−1

C=5(18.1)−1= 90.5 - 1=89.5

So A=18.1, B=72.4, and C=89.5

Hope this helps!

The size of ∠A is 18.1°.

The size of ∠B is  72.4°.

The size of ∠C is 89.5°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle ABC

∠A = x

∠B = 4x

∠C = 5x - 1

Now,

The sum of all the angles in a triangle is 180.

This means,

x + 4x + 5x - 1 = 180

10x - 1 = 180

10x = 181

x = 18.1

Now,

∠A = 18.1°

∠B = 4 x 18.1 = 72.4°

∠C = 5 x 18.1 - 1 = 89.5°

Thus,

The sizes of the angles are:

18.1°, 72.4°, and 89.5°

Answer:

w = 2.63157894736

Step-by-step explanation:

8w+3-2w=11(-4w+2) | Given

6w + 3 = -44w + 22 | Combine like terms & distribute

50w + 3 = 22 | Add 44w to both sides

50w = 19 | Subtract 3 from both sides (simplified)

w = 2.63157894736 | Divide both sides by 50 (value of w)

Answer:

x = 2.4/20= 0.12

Step-by-step explanation:

Multiply both sides by 4 to eliminate the fraction 1/4:

1      20

--- = ------

x      2.4

Next, we cross-multiply.  This eliminates the fractions:

20x = 2.4

Dividing both sides by 20 results in an equation for x:  x = 2.4/20= 0.12

Answer:

I think its 6 not sure

Step-by-step explanation:

Slope = change in Y / change in x:

Slope = (5- 5) / (-1 - -9)

Slope = 0/8

Because the change in Y = 0, the slope = 0

Slope = 0

Answer:

0

Step-by-step explanation:

(-9,5) and (-1,5)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(5 - 5) / (-1 - 9)

Simplify the parentheses.

= (0 ) / (-10)

Simplify the fraction.

0/-10

= 0

This is your slope.

This is also a horizontal line, which will have a slope of 0.

Answer:

0.25

Step-by-step explanation:

Bag 1 :

Number of marbles = 6

Number of Blue marbles = 3

Bag 2:

Number of marbles = 4

Number of Blue marbles = 2

Recall :

Probability = required outcome / Total possible outcomes

For Bag 1:

P(blue) = Number of Blue marbles / total marbles

P(blue) = 3 / 6 = 1/ 2

For Bag 2:

P(blue) = Number of Blue marbles / total marbles

P(blue) = 2 / 4 = 1/ 2

Probability of a picking a blue marble from each bag :

1/2 * 1/2 = 1/4 = 0.25

That is your triangle.

Now, since its a right triangle, we can use the Pythagorean theorem to solve for x.

The equation for the Pythagorean theorem is this: [tex]A^{2} + B^{2} = C^{2}[/tex]

So we plug in the values.

[tex](x^{2} ) + (x-9)^{2} = (x + 9)^{2}[/tex]

We solve for x.

[tex]x^{2} + x^{2} -18x + 81 = x^{2} + 18x + 81[/tex]

Get everything to the left side of the equation. (x^2 + x^2 = 2x^2, - x^2 = x^2;

-18x - 18x = -36x;    81 - 81 = 0)

[tex]x^{2} -36x = 0[/tex]

Add 36x to both sides, then divide by x.

[tex]x^{2} = 36x\\\\x = 36[/tex]

Shortest Leg = 36 - 9 = 27

Longest Leg = 36

Hypotenuse = 45
