Answer:

20, 40, and 120

Step-by-step explanation:

x, 2x, and 6x have one thing in common: X. X is the same number throughout so if we find x we can just finish the equation by multiplying x by its coefficient.

x+2x+6x = 180. (Sum of angle measures)

9x = 180 (Add up the left side)

9x/9 = 180/9 (Divide both sides by 9 to cancel out the 9 and leave the x)

x = 20

Now we know what x is so:

Angle 1 = 20. (We know x is 20, so that one is easy.)

Angle 2 = 40 (Simply 2*x or 2*20)

Angle 3 = 120 (Simply 6*x or 6*20)

A cheetah runs at a rate of 75 miles per hour about how many leaders can it run in 5 seconds

umka21 [38]

Answer:

Distance in meters D = 167.75 meters

Step-by-step explanation:

Distance covered in 5 seconds is given by:

Distance, D = Speed (S) X Time (T)

Where,

Distance = ?

Speed = 75mph

Time = 5s

Since we are calculating distance in meters, we have to convert 75miles per hour to meters per second

75mph = 75miles/1hr X 1km/0.621miles X 1000m/1km X 1hr/60mins X 1min/60s

= (75X1000) / (0.621X60X60) meter per second

= 75000/2235.6 meter per second

= 33.55 meter per second

∴ Distance D = 33.55 meter per second X 5 seconds

= 167.75 meters

Show that y2+ x-3 =0 is an implicit solution to dy/dx =-1/ (2y) on the interval (- [infinity] , 3)

Sedaia [141]

Answer:

Implicit function

$\frac{d y}{d x} = \frac{-1}{2y}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given y² + x - 3=0 ...(i)

Differentiating equation (i) with respective to 'x', we get

$2 y \frac{d y}{d x} +1 = 0$

⇒ $2 y \frac{d y}{d x} = -1$

⇒ $\frac{d y}{d x} = \frac{-1}{2y}$

$\frac{d y}{d x} = \frac{-1}{2 (3)}$

$\frac{d y}{d x} = \frac{-1}{6}$
