Circle D is below what is the arc measure of BC in degrees

maks197457 [2]

Answer:

84°

Step-by-step explanation:

$\because (13n - 16) \degree + (7n + 12) \degree + (6n)\degree \\= 360\degree \\ \\ \therefore \: (26n - 4) \degree= 360\degree \\ \\ \therefore \: 26n - 4= 360 \\ \\ \therefore \: 26n = 360 + 4 \\ \\ \therefore \: 26n = 364 \\ \\ \therefore \: n = \frac{364}{26} \\ \\ \therefore \: n = 14 \\ \\\because m\overset { \frown}{BC} = (6n)°\\ \\\therefore \:m \overset { \frown}{BC} =(6\times 14)° \\ \\ \huge \purple {\boxed {\therefore \:m\overset { \frown}{BC}= 84°}} \\$

Sherry is driving 390 miles to visit The gateway arch in St. Louis. She drives at an average rate of 65 miles per hour. Explain

grandymaker [24]

Answer:

t = 6 s

Step-by-step explanation:

Given that,

Sherry is driving 390 miles to visit The gateway arch in St. Louis.

She drives at an average rate of 65 miles per hour.

We need to find the amount of time it will take Sherry to get to the arch. Let the time is t.

Speed = distance/time

$t=\dfrac{d}{v}\\\\t=\dfrac{390}{65}\\\\t=6\ h$

Hence, it will take 6 hours to get to the arch.

The sum of two numbers is 98. their difference is 22. write a system of equations that describes this situation. solve by elimin

larisa [96]

Y+x=98
y-x=22

I'm going to use elimination.

y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60.

Substitute that into either equation and you get y=60 and x=38

Have a nice day! :)
