Answer:

b) 36

Step-by-step explanation:

ratio of angles = 3:5:7

The angles are 3x, 5x , 7x

Sum of all the three angles of triangle = 180

3x + 5x + 7x = 180

15x = 180

x = 180/15

x = 12

Measure of smallest angle = 3x = 3*12 = 36

What is the solution to this equation 1/2n^2+18=0

ololo11 [35]

Answer:

n = ±6 .

Step-by-step explanation:

A quadratic equation is given to us and we need to find out the solution of the given equation . The given equation is ,

$\rm\implies -\dfrac{1}{2}n^2+18=0$

Subtracting 18 both sides ,

$\rm\implies -\dfrac{1}{2}n^2 = -18$

Multiplying both sides by -2 ,

$\rm\implies -2\times\dfrac{1}{2}n^2 = -2\times -18$

On simplyfing , we get ,

$\rm\implies n^2= 36$

Putting squareroot both sides ,

$\rm\implies n= \sqrt{36}$

This equals to ,

$\rm\implies \boxed{\quad\blue{\rm n =\pm 6 }}$

Hence the value of n is ±6 .

Answer:

The elevation of Lucas Oil Field is of 715 feet.

Step-by-step explanation:

Elevation of Sports Authority Field:

Of 5280 ft.

Compared to Lucas Oil Field:

275ft than seven times the Lucas Oil Field elevation of x.

Equation:

$275 + 7x = 5280$

What is the elevation of Lucas Oil Field?

Solving the above equation:

$7x = 5280 - 275$

$7x = 5005$

$x = \frac{5005}{7}$

$x = 715$

The elevation of Lucas Oil Field is of 715 feet.
