Answer:
We have a quotient between a 2 digit number and a 4 digit number.
The usual rule for this type of problems is:
If the denominator has n more digits than the numerator, then the first digit will be in the nth position at the right of the decimal point.
If also, the denominator is larger than the numerator times 10^n, then the decimal will be moved another place to the right.
For example, if we divide 10 by 100 we have:
10/100
The denominator has one more digit than the numerator, then n = 1.
this means that the first digit of the quotient, will be on the first place at the left of the decimal point.
We can solve the quotient to get:
10/100 = 0.1
And, as we predicted, the first decimal is in the first place.
Now, with our quotient we have:
32/8032
n = 2.
and:
32*10^n = 3200
The denominator is larger than this, then we will move the first decimal to another place to the right.
Then we should expect to have the first decimal in the third place after the decimal point.
We can solve the quotient to get:
32/8032 = 0.0039
As we expected.

David made a scale drawing of an Olympic-sized pool the pool is 20.5 in long and the drawing that I can shoot pool is 164 ft long what is the correct scale of the drawing
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

1. **What is the slope of a line that passes through the points (-1,30) and (4, 10)
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.

x/3 + y =2
slope = -x/y
= -( 1/3 ) /1
= -1/3
blank + blank = internal energy
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.

Maya invested $5,000 in an account paying an interest rate of 3.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $6,880?
Answer: 8.2
Step-by-step explanation:
Delta Math Solution
It would take 2.92 years for the value of the account to reach $6,880.
What is Compound interest?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.

What is a unitary method ?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

At a theater, the admission price for children is $4 and the admission price for adults is $7. The total amount the theater collects in admissions for the day is $1782. The total number of visitors is 294. Let x be the number of children and let y be the number of adults.
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

find the highest common factor of 14(3x+1)^ and 7(3x+1)
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)

The following table shows the number of alligators in each body of water near Tom's house. Number of alligators 7,0,11,10 find the mean number of alligators.
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)
