Pure gold is 24 karats.
14-karat gold is 14/24 pure gold.
2.5 oz * 14/24 = 1.458333... oz
Answer:
x ≈ 25.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° =
=
( multiply both sides by x )
x × sin26° = 11 ( divide both sides by sin26° )
x =
≈ 25.1 ( to 1 dec. place )
3+2+1/2+1/7
5+1/2+1/7
5+7/14+2/14
5+9/14
5 9/14
The inverse is where the x and y values are flipped, so the left side would have 6 7 8 9 and the right side would have 9 10 11 12 for the inverse.
Therefore your answer is A.
