S=r*theta where s is arc length and the r is radius and theta is in RADIANS ONLY!! If you use degrees this formula does not work.

So we have a arc length of 38.485ft and a radius of 7. So rearranging the formula for theta, we get;

theta=(38.485)/(7)= 5.498radians then to convert to degrees if needed just take;

5.498rad*(180/pi)= 315deg

(7y is supposed to be 7x)

Andrei [34K]

Answer:

Step-by-step explanation:

Angle E is (7x+27) because it is corresponding.

So, 7x+27+15x-5=180 (angle on a straight line is 180 degrees

22x+22=180

22x=158

x= 158/22 = 7.18'

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb

olga2289 [7]

Answer:

3x = 50 - 10y

Step-by-step explanation:

Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,

So, total weight of 3 lb weights = 3x

And, the weight of 10 lb weights = 10y

Total weight of all his weights = 3x + 10y

According to the question,

Total weight = 50 lb,

⇒ 3x + 10y = 50

Or 3x = 50 - 10y

Which is the required equation.

Second option is correct.

Distribute 6(c - 3)?

Ilya [14]

Answer: The blue diamond "6c-18"

Step-by-step explanation:

Because the 6 would distribute with the c, so 6c, then it would distribute with the 3, which would be 18, because 6x3=18. Then the equation becomes 6c-18
