You have to change the denominator of 6/10 into 100 then you will get 60/100 then you add 15/10+60/100

zavuch27 [327]

If the length is X

X+X+X = 9X+6

-6X=6

X=-1

but because length can't be negative X=1

Gilda drove 650miles at an average speed of 50 miles per hour.how many miles per hour faster would she have had to drive in orde

zzz [600]

T=650mi(hr/50mi)=13 hr

t-1=12 hr

12=650/(50+v) multiply both sides by 50+v

600+12v=650 subtract 600 from both sides

12v=50 divide both sides by 12

v=25/6 mph

v≈4.17mph

What is the answer for this question?

grandymaker [24]

Answer:

A

Step-by-step explanation:

$\frac{11\pi }{6}$ is in the fourth quadrant where tan < 0

The related acute angle = 2π - $\frac{11\pi }{6}$ = $\frac{\pi }{6}$

Hence

tan( $\frac{11\pi }{6}$ )

= - tan( $\frac{\pi }{6}$ )

= - $\frac{1}{\sqrt{3} }$

= - $\frac{1}{\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$

= - $\frac{\sqrt{3} }{3}$ → A
