Each week Rosario drive to an ice-skating rink that is 60 miles away. The road trip takes 2.75 hours. If he averages 55 mph on h

is way to the rink, which equation can be used to find X, the number of miles per hour he averages on his way home?

60(55)•60x=2.75 there's your answer

Answer: The number of miles per hour he averages on his way home is 36 mph.

Step-by-step explanation:

Since we have given that

Distance traveled by Rosario = 60 miles

Time taken for road trip = 2.75 hours

Speed at which he on his way to the rink = 55 mph

Let X be the speed at which he averages on his way home.

So, According to question, we get that,

\dfrac{60}{55}+\dfrac{60}{x}=2.75\\\\1.09+\dfrac{60}{x}=2.75\\\\\dfrac{60}{x}=2.75-1.09\\\\\dfrac{60}{x}=1.659\\\\x=\dfrac{60}{1.659}\\\\x=36.16\\\\x=36\ mph

Hence, the number of miles per hour he averages on his way home is 36 mph.

Answer:

x = 9.

Step-by-step explanation:

-5 square root x =15

divide both sides by -5:

√x = 15/-5 = -3

the angle theta is in the second quadrant and cos theta = -2/√29 determine possible coordinates for point P on the terminal arm
Gekata [30.6K]

\cos(\theta)=-\frac{2}{\sqrt{29}} and $\theta$ lies in $2^{\text{th}}$ quadrant.

where, $x-$ coordinate is negative, and $y-$ coordinate is positive

so it can't a.

now, cosine means, side adjacent over the hypotenuse, in Cartesian plane, that will be $x-$ coordinate over the distance from origin.

Assume the triangle , with base $2$ units and hypotenuse $\sqrt{29}$ and it's in second quadrant. (so \cos(\theta)=-\frac{2}{\sqrt{29}})

now, the leftmost point on $x-$ axis is , obviously $(-2,0)$

and by Pythagoras theorem, we can find the perpendicular side, that will be $y^2=(\sqrt{29})^2-(2)^2\implies y=5$

so the coordinates of the upper vertex is $(-2,5)$, each point lying on this "ray" should have equal ratio of respective coordinates. i.e. $\frac25=\left|\frac xy\right| $

and it should lie on second quadrant, so $x<0 \, y>0$

Option d satisfies this.
