Answer:

Diamter=7 meter

Step-by-step explanation:

One full turn means we have 360° of theta which equals 2pi in radinas

And arc length is 22 so using the equation theta= L/r = 2pi=22/r so r= 3.50 and diameter= 2r =7 m

<h3>Answer:  29 miles (approximate)</h3>

======================================================

Explanation:

Segment AB is already given to be 19 miles long.

I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.

Use the law of cosines to find the missing side

a^2 = b^2 + c^2 - 2*b*c*cos(A)

a^2 = 12^2 + 19^2 - 2*12*19*cos(138)

a^2 = 843.874040417691

a = sqrt(843.874040417691)

a = 29.0495101579647

a = 29 when rounding to the nearest whole number

Side BC is roughly 29 miles long.

Need help with question 3. ASAP PLS. Much appreciated :)

Emma is running faster than Maggie. The point on the graph where the two lines intersect represents the spot on the running track where Maggie and Emma are at the same distance from the starting point.
Since Emma starts ahead of Maggie, Maggie has to run FASTER to catch up with Emma.
I hope this helps :)

Find the slope of the line through each pair of points

The answer is 27/23. The way you listed the answers is confusing so I’m not giving a letter. Because [17+10]/[17+6]= 27/23

Solve each inequality, graph the solution on the number line, and write the solution in interval notation
Lubov Fominskaja [6]

Answer:

(-\infty,+\infty)

Step-by-step explanation:

The given inequality is 3x-2>4 or 5x-3\leq 7

We group similar terms to obtain: 3x>4+2 or 5x\le7+3

Simplify to get:

3x>6 or 5x\le10

x>2 or x\le 2

This implies that the solution set is all real numbers.

The solution in interval notation is (-\infty,+\infty)
