2*a+5-(9*a-16)=0 witch equals <span> a=3</span>
Answer:
A
Step-by-step explanation:
∠ABC is formed by 2 tangents to the circle and is measured as
∠ABC = 
(m arc ADC - m arc AC ), that is
(y - 119) = 61 → A
Circumference = 2*pi*r = 27"
Solve for r
r=27"/(2*pi)
=27"/(2*3.14159265)
=4.297..."
=4.30" (to the nearest hundredth of an inch)
Answer:
12.5 inches of gold chain.
Step-by-step explanation:
To get the remaining chain of gold we need to calculate
8/8 - 3/8 = 5/8 of 20 inches
then multiply:
20 * 5/8 = 100/8
100/8 = 12.5 inches
I multiply 1200 times 5 and yet 6000 because it says what is the height
