2.Add the numbers
15n+24-4n+12+6-2n=105
15n+42-4n-2n=105
3.Combine like terms
15n+42-4n-2n=105
9n+42=105
4.Subtract 42 from both sides of equation
9n+42=105
9n+42-42=104-42
Simplify
Subtract
9n+42-42=105-42
9n=105-42
subtract again
9n=63
Divide both sides of the equation by the same term
9n=63
9n/9=63/9
Simplify
Cancel terms that are in both the numerator and denominator
9n/9=63
n=63/9
Divide the numbers
n=7
so the answer is n=7

This box plot shows information about the marks scored in a test.
a) What was the median number of marks scored?
b) What was the interquartile range of the marks?
c) What was the range of the marks?
Answer:
a) 58
b) 38
c) 76
Step-by-step explanation:
a) Here we want to get the median
The median of the number is the 3rd line
The value here is 58
b) The interquartile range is the difference between the first and third quartile
The third quartile is the 4th line and its value is 72
The first quartile is the second line which is 34
The interquartile range is thus; Q3-Q1
= 72-34 = 38
c) The range is the difference between the highest and lowest values
The highest value is 86
The lowest value is 10
The range is thus;
86-10 = 76

Show your work and explain. How many pounds of oranges cost $12? Show your work.
due today.
Answer:
Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8

The shadow cast by a lampshade has a boundary in the shape of a hyperbola defined by the equation StartFraction (y minus 3) squared Over 2 EndFraction minus StartFraction x squared Over 1 EndFraction = 1. What could the center of the hyperbola represent?
the location of the light bulb
the bottom of the lampshade
the top of the lampshade
a vertex of the shadow
Answer:
A THE LOCATION OF THE LIGHT BULB
I got this right on the assignment
Step-by-step explanation:
The centre of the hyperbola represent will represent the location of the light bulb.
What is the centre of a hyperbola?The centre of a hyperbola is the midpoint of the line segment joining its foci. The transverse axis is the line segment that contains the centre of the hyperbola and whose endpoints are the two vertices of the hyperbola.
As we know that the centre of a hyperbola is the midpoint of the line segment joining its foci. Now, if we plot the hyperbola with equation
[tex]\dfrac{(y-3)^2}{2}-\dfrac{x^2}{1}=1[/tex]
The hyperbola will look like the one given in the below image, further if draw two lines to know the centre of the hyperbola, we will find that the centre of the hyperbola will lie at coordinate (0,3).
Further, the centre of the hyperbola represents the light bulb while the hyperbolas will represent the shadow cast by the lampshade.
Hence, the centre of the hyperbola represent will represent the location of the light bulb.

© The mean temperature for the first 4 days in January was -4°C.
The mean temperature for the first 5 days in January was -6°C.
What was the temperature on the 5th day?
Answer: The temperature on the fifth day is -14°C
Step-by-step explanation:
When we have a set of N elements, that can be written as:
{a₁, a₂, ..., aₙ}
The mean of these N elements is be written as:
Mₙ = (a₁ + a₂ + ... + aₙ)/N
Now, when we take in account the temperature for the first four days of January, we will have a set of 4 elements, {a₁, a₂, a₃, a₄}
Where each one of these elements represents the temperature of one particular day.
The mean temperature for the first four days will be:
M₄ = (a₁ + a₂ + a₃ + a₄)/4
And we know that this is equal to 4°C
Now we also could do the next replacement:
(a₁ + a₂ + a₃ + a₄) = T
Then we can write:
M₄ = -4°C = (a₁ + a₂ + a₃ + a₄)/4 = T/4
Then we can solve:
-4°C = T/4
-4°C*4 = T
-16°C = T
This is the sum of the temperatures for the first four days of January.
Now we know that the mean for the first five days is -6°C
Then we have:
M₅ = (a₁ + a₂ + a₃ + a₄ + a₅)/5 = -6°C
Where a₅ is the temperature on the fifth day of January, which is the value we want to find.
And we know that:
a₁ + a₂ + a₃ + a₄ = -16°C
We can replace that in the equation to get:
(-16°C + a₅)/5 = -6°C
(-16°C + a₅) = 5*(-6°C) = -30°C
a₅ = -30°C + 16°C = -14°C
a₅ = -14°C
The temperature on the fifth day is -14°C

Plss answer me fast im in test
Answer:
Suppose that we have a circle of radius R.
The total perimeter of this circle will be:
P = 2*pi*R
Where pi = 3.14159...
Now, if we have a section of this circle with an angle A, the "chord" of this section will be:
C = (A/360°)*2*pi*R.
Where you can see that if A = 360° (so the section is the whole circle) the chord is equal to the perimeter.
In this particular case, the chord is equal to the radius of the circle, then we get:
C = R = (A/360°)*2*pi*R
We need to solve this for A.
R = (A/360°)*2*pi*R
We can divide both sides by R to get:
1 = (A/360°)*2*pi
Now we need to isolate A.
(360°/2*pi) = A = 57.3°
This would be the angle in the minor arc.
And the angle for the mayor arc would be the difference between the angle for a whole circle (360°) and the angle of this section (57.3°)
The angle for the major arc is:
A = 360° - 57.3° = 302.7°

many dimes does paul have?
Answer:
#nickels = 50

Step-by-step explanation:
system of equations:
n + d = 150
.05n + .10d = 12.50
let n = '150 - d' and substitute this into the second equation
.05(150-d) + .10d = 12.5
7.5 - .05d + .10d = 12.5
.05d = 5
d = 5/.05
