3- 5/9= 2.45
3- 23/9= .45
2.45/.45= 5.44
5.44^3/2= 81
It's a complementary angle, so just solve for x and subtract the CBD from 90,
First, we have to solve for x.
2x + 14 + x + 7 = 90
Combine like terms
3x + 21 = 90
Balance, subtract 21 from each side.
3x = 69
Divide 3 from each side
x = 23.
So know that we know x is 23, we can go about it 2 ways, subtracting the other angle with 90 or just substituting the variable, I'd just substitute the variable for it so just do 23 + 7. That equals 30, angle ABC = 30.
A straight line is 180 degrees. As a result, 180-35=x, or x=145
Just do 198 divide by 33. The answer is how much gas will be used.
Answer:
552.920307 yd^2 or 552.92 yd^2 for sigfigs
Step-by-step explanation:
basically you take the area of the entire circle and subtract the interior circle to leave the ring and that’s your answer
so the area formula of a circle is π r^2
the radius (r) is just half the diameter so the entire diameter is 48 so the radius is 24 - π(24)^2 = 1809.557368^2
then the interior circle’s diameter is 40 so the radius is 20 - π(20)^2 = 1256.637061^2
so now it’s just subtraction:
1809.557368 yd^2 - 1256.637061 yd^2 =
552.920307 yd^2 or 552.92 yd^2 for sigfigs
hope this helps :)
