First you would take both radius' and add them. Once you add them, subtract the sum by 42. that will give you the distance between the gap of the circles. now that you have that distance, add 19 and 11 and your result is your final answer.
6/15 simplified is 3/5 so the ratio can be written as:
3 to 5
3:5
3/5
<span>In this problem the formula for average credit card debt is D=393t+5680 where t is years after 1995. To find the total average credit card debt in the year 2027, we must first find the difference in years between 2027 and 1995 to get our t value. To do this subtract 1995 from 2027: t= 2027 - 1995 = 32 years. Next, we plug in 32 for t into the equation and solve for D: D = (393)*(32) + 5680 = $18,256.</span>
Given the measure of angle B, side b and side, the measure of angle C to the nearest whole number is 43 degrees.

What is the measure of angle space C?</h3>
From the Rule of Sine;
sinA/a = sinB/b = sinC/c
Where A,B and C are the angles of the triangle and a, b and c are the corresponding opposing sides.
Given that;
- Angle B = 18°
- side b = 9
- side c = 20
- Angle C = ?
Using the rule of sine.
sinB/b = sinC/c
We substitute the given values into the equation
sin( 18° )/9 = sinC/20
We solve for C.
sin( 18° ) × 20 = sinC × 9
0.309016994 × 20 = sinC × 9
6.18033988 = sinC × 9
Divide both sides by 9
6.18033988/9 = (sinC × 9)/9
sinC = 0.686704431
C = sin⁻¹( 0.686704431 )
C = 43.3697°
C = 43°
Given the measure of angle B, side b and side, the measure of angle C to the nearest whole number is 43 degrees.
