Solve the equation. n over 10 plus space 7 space equals space 10
UNO [17]

Answer:

30

Step-by-step explanation:

Given the equation;

n/10 + 7 = 10

We are to find the value of n

Subtract 7 from both sides

n/10 + 7 - 7 = 10 - 7

n/10 = 3

Cross multiply

n = 10 * 3

n = 30

<em>Hence the solution to the equation is 30</em>

Find the ends of the major axis and foci
poizon [28]

The ends of the major axis is = (0, ± 13) and that of the foci is: (0,±5).

<h3>What is the axis and foci about?</h3>

The term 'foci' is known to be the point at which there is the coming together of light or any other kinds of electromagnetic radiation, particles, etc.

It is also seen as the point from which they seems to go apart.

\frac{x^{2} }{144} + \frac{y^{2} }{169}  = 1

\frac{x^{2} }{12^{2} } + \frac{y^{2} }{13^{2} }

Hence, major axis is = (0, ± 13)

e = \sqrt{1 -\frac{12^{2} }{13^{2} } }

= 5/13

Foci is: (0± 13 x \frac{5}{13})

Foci is: (0, ±5)

Therefore, The ends of the major axis is = (0, ± 13) and that of the foci is: (0,±5).

Solve for the rate in the eqution d=rt
Zolol [24]

Answer:

<em>The rate of the equation is r when r is a constant</em>

Step-by-step explanation:

     We need to solve for the rate of the equation  

     d = rt

     Differentiating on both sides with respect to time

     \frac{\mathrm{d} d}{\mathrm{d} t} = \frac{\mathrm{d} rt}{\mathrm{d} t}

      Considering r as a constant

       \frac{\mathrm{d} d}{\mathrm{d} t} =  r×\frac{\mathrm{d} t}{\mathrm{d} t}

      where, \frac{\mathrm{d} t}{\mathrm{d} t} = 1

       \frac{\mathrm{d} d}{\mathrm{d} t} = r

     <em>  The rate of the equation is r when r is a constant</em>
