Answer:

  21 3/7 mL ≈ 21.43 mL

Step-by-step explanation:

Let x represent the amount of 6% solution that should be added. The the total volume of sodium carbonate in the mix is ...

  1%(50) +6%(x) = 2.5%(50 +x)

  50 +6x = 125 +2.5x . . . . . multiply by 100, eliminate parentheses

  3.5x = 75 . . . . . . . . . . . . . subtract 2.5x+50

  x = 21 3/7 . . . . . . . . . . . . . divide by 3.5

21 3/7 mL, about 21.43 mL, of 6% solution should be added to make a 2.5% solution.

Answer:

Slope = -4

Step-by-step explanation:

Given points are :

(-1,30) and (4, 10)

We need to find the slope of the line that passes through these points.

We know that, the formula for the slope of line is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

Put values in the above formula.

[tex]m=\dfrac{10-30}{4-(-1)}\\\\=\dfrac{-20}{5}\\\\=-4[/tex]

So, the slope of the line is -4.

Answer:

[tex]-\frac{3}{5}[/tex]

The slope is -3/5

Step-by-step explanation:

Answer:

y=3/5x-2

Step-by-step explanation:

Right now, this equation is in standard from or Ax^2 + Bx = C and you need to convert it to slope-intercept from which is y=mx+b where m is the slope and b is the y-intercept

Convertion

3x-5y=10   Subtract 3x from both sides

-5y=-3x+10    Divide all terms by -5

You get

y=3/5x-2

Delta Math Solution

It would take 2.92 years for the value of the account to reach $6,880.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

Maya deposited $5,000 in an account with a 3.9% compounded annual interest rate.

To solve this problem, we can use the formula for continuously compounded interest: [tex]A = Pe^{rt}[/tex], where A is the final amount of the investment, P is the initial amount of the investment, r is the interest rate, and t is the time in years.

We can rearrange the formula to solve for t: t = (ln(A/P)) / r

Plugging in the values from the problem, we get: t = (ln(6880/5000)) / (3.9/100) = 2.92 years

Rounded to the nearest tenth of a year, this is approximately 2.9 years.

Answer:

kinectic + electric = internal

Step-by-step explanation:

Internal energy U of a system or a body with well defined boundaries is the total of the kinetic energy due to the motion of molecules and the potential energy associated with the vibrational motion and electric energy of atoms within molecules. Internal energy also includes the energy in all the chemical bonds.

Answer:

The internal energy of a system is identified with the random, disordered motion of molecules; the total (internal) energy in a system includes potential and kinetic energy. This is contrast to external energy which is a function of the sample with respect to the outside environment (e.g. kinetic energy if the sample is moving or potential energy if the sample is at a height from the ground etc). The symbol for Internal Energy Change is ΔU .

Energy on a smaller scale

Internal energy includes energy on a microscopic scale

It is the sum of all the microscopic energies such as:

translational kinetic energy

vibrational and rotational kinetic energy

potential energy from intermolecular forces

One gram of water at zero °Celsius compared with one gram of copper at zero °Celsius do NOT have the same internal energy because even though their kinetic energies are equal, water has a much higher potential energy causing its internal energy to be much greater than the copper's internal energy.

Answer:

[tex]Scale = 1\ in : 8\ ft[/tex]

Step-by-step explanation:

Given

[tex]Scale\ Measurement = 20.5in[/tex]

[tex]Actual\ Measurement = 164ft[/tex]

Required

Determine the scale

The scale is calculated using the following ratio:

[tex]Scale = Scale\ Measurement : Actual\ Measurement;[/tex]

Substitute values for Scale and Actual Measurements

[tex]Scale = 20.5\ in : 164\ ft[/tex]

Divide ratio by 20.5

[tex]Scale = 20.5/20.5\ in : 164/20.5\ ft[/tex]

[tex]Scale = 1\ in : 8\ ft[/tex]

This implies that: 1 inch on scale represents 8 ft in actual measurement

Answer:

Mean number of alligators = 7

Step-by-step explanation:

Given that:

Number of alligators

7, 0, 11, 10

Sum of quantities = 7 + 0 + 11 + 10

Sum of quantities = 28

Number of quantities = 4

We can find the average by dividing the sum of quantities by number of quantities.

Mean = [tex]\frac{28}{4}[/tex]

Mean = 7

Hence,

Mean number of alligators = 7

Answer:

7

Step-by-step explanation:

So there were four different places and four different amounts of alligators.

The numbers are 7, 0, 11, 10.

When you add 7, 0, 11, 10, you get the number, you get 28.

You then divide 28 by 4, because there are four different numebrs on the chart. 7(1), 0(2), 11(3), 10(4).

After you divide this, the mean would be 7 because 28/4 = 7. (28/4 means 28 divided by 7)

Answer:

The highest common factor is 7(3x+1)

Step-by-step explanation:

Here, we want to find the highest common factor of both expressions

As we can see, the highest common factor of 7 and 14 is 7

Now, we have the second expression which is (3x+1)

No matter what the first expression is raised to, it still stands that the highest common factor we shall have there is 3x+ 1 as concerns the term

inside the bracket

Thus, the highest common factor of both terms is 7(3x + 2)

Answer:

If you need to find the hypotenuse, then square the two sides and add them together then square root that answer to get the hypotenuse. If you need to find a side then take the hypotenuse and other side and square them then subtract the side by the hypotenuse and then square root that answer.

Step-by-step explanation:

legs; a b hypotenuse c

a^2 + b^2 = c^2 then square root this answer

c^2 - b^2 = a^2 then square root this answer

c^2 - a^2 = b^2 then square root this answer

Step-by-step explanation:

A bunny seller began their business with only 2 bunnies. The seller noticed that the number of bunnies the farm expanding after t days can be modeled by the equation

[tex]P=2(3)^t[/tex]

we know that the exponential equation is in the form of

[tex]y=a(b)^x[/tex]

Where 'a' is the initial value

y is the final value

b is the rate factor

x is the time period

P=2(3)^t

[tex]3^3[/tex] represent the value of t is 3

we know that 't' represents the number of days

[tex]3^3[/tex] represent the farm expanding after 3 days

Answer:

4x+7y=1782 i beleive it would be

Step-by-step explanation:

Answer:

 x + y = 294   (1)

4x + 7 y = 1782 (2)

(1) => x=294-y  replace x into (2)

=> 4( 294-y ) + 7y = 1782 => y = 606/3 =202

=> x = 294 - 202 = 92

So : x = 92 and y = 202

Answer:

14dimes and 5 nickels

Step-by-step explanation:

Tim have 14 dimes and 5 nickels.

In simple terms, the unitary method is used to find the price of a single unit from a given multiple.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that there are 19 nickels, let n=number of nickels.

The number of total coins subtracted by number of nickels will give us the number of dimes.

The Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)

Then we can substitute total as $1.65 and get the value of nickels by multiplying by 5cent

Since the value of the dimes is the value of nickels subtracted from the total, we can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.

5(n)=5(19)=95

(165-95)/10 =number of dimes

70/10 = 7dimes
