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.

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)

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

Step-by-step explanation:
Write the equation of a line perpendicular to y= -5/6x-3 and whose y-intercept is (0,11).
Answer:
y=6/5x+11
Step-by-step explanation:
Perpendicular lines have the opposite sign and reciprocal of the original line. Since the y-intercept is 11 we know that it is 6/5x+11

7. In the right triangle below, find the length of the third side.
B
15
10
C
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
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 P = 2 ∙ 3^t In this equation, what does 3^3 represent? *
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
Alex and Sophia share £20 in the ratio of 2:3. Work out how much money each person gets.
Answer:
Alex will get 8 pounds and Sophia will get 12 pounds
Step-by-step explanation:
Since the ratio is 2:3, the total ratio is 5 (2+3)
divide 20 pounds from 5
and each unit will have 4 pounds
Therefore, Alex will get 8 pounds and Sophia will get 12 pounds
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.
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)

do you want to make a sodium carbonate solution with a concentration of 2.5%. You have 50 mL of a 1% solution about how many milliliters of a 6% solution should you add
9514 1404 393
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.

The slope of y = 4x – 2 is
The slope of a line parallel to y = 4x – 2 is
The equation of the line parallel to y = 4x - 2 that passes through the point (-1,5) is y =
write in slope intercept form
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
25 = 5 • 3 = 15 True or False
Answer:
False
Step-by-step explanation:
How many points does the team have?
How many games has this team lost?
Step-by-step explanation:
P = 3W + D
When W = 5 and D = 3, P = 3(5) + 3 = 18.
When P = 50 and D = 14,
(50) = 3W + (14), 3W = 36, W = 12.
Since the team has 12 wins and 14 draws,
they have 35 - 12 - 14 = 9 losses.
