The answer is 18.75% (I THINK, I'm not very good at maths!) here's how I worked it out:
4.5 + 4 1/2 so for the first part it is a fraction 4.5/15 you then multiply this to 5/8 and get 225/120 which you can then simplify to 3/16 then you work out 3 divided by 16 and get 0.1875 and multiply this decimal by 100 to get the percentage, 18.75%.
Hope this helped, but check with other people (I'm not very good at maths)!

Answer:
98°
Step-by-step explanation:
Inscribed angle FGH is half the measure of the intercepted arc FH. The measure of arc FH is identical to the measure of central angle FIH. So, angle FIH has twice the measure of inscribed angle FGH:
∠I = 2×∠G = 2×49°
∠I = 98°
Answer:
$21.55
Step-by-step explanation:
21.50 + 44.95 + 12 = $78.45
100 - 78.45= $21.55
Answer:
=1/8
Step-by-step explanation:
1
Subtract 33 from both sides.
8x=4-38x=4−3
2
Simplify 4-34−3 to 11.
8x=18x=1
One would note, that, you never really asked anything above
but.. in case you meant as in proof on the identities
well, doing the left-hand-side
