N-31/4 =2 simple equation

Mathematics
1 answer:
Zanzabum3 years ago
6 0

Answer:

n = 5.75

Step-by-step explanation:

original equation

n - 31/4 = 2

multiply everything by 4

n * 4 - 31/4 * 4 = 2 * 4

simplify

4n - 31 = 8

add 31 to both sides

4n - 31 + 31 = 8 + -31

simplify

4n = -23

divide both sides by 4

4n/4 = -23/4

simplify

n = 5.75

4. A horizontal ellipse, centered at the origin has a major axis of 10 units and minor axis of 8 units. Write the
s2008m [1.1K]

Answer:

\frac{x^2}{25} +\frac{y^2}{16} =1

Step-by-step explanation:

For ellipses, the length of the major axis is represents as:

Major axis = 2a

where a is called the semi-major axis.

In this case since the major axis is equal to 10 units:

10=2a

solving for the semi-major axis a :

a=10/2\\a=5

and also the minor axis of an ellipse is represented as:

Minor axis = 2b

where b  is called the semi-minor axis.

Since the minor axis has a length of 8 units:

8=2b

solving for b:

b=8/2\\b=4

Now we can use the equation for an ellipse centered at the origin (0,0):

\frac{x^2}{a^2} +\frac{y^2}{b^2} =1

and substituting the values for a and b:

\frac{x^2}{5^2} +\frac{y^2}{4^2} =1

and finall we simplify the expression to get the equation of the ellipse:

\frac{x^2}{25} +\frac{y^2}{16} =1

Math question please help!!!
mars1129 [50]

Answer:

Option B. 75

Step-by-step explanation:

we know that

<u>A negative correlation</u> or inverse correlation is a relationship between two variables such that as the value of one variable increases, the other decreases

we know that

For L1=150, K1=7

so

For K2=14, L2=?

we have that

L1*K1=L2*k2

substitute the values

150*7=L2*14

L2=150*7/14

L2=75
