Ametal bar weighs 8.15 ounces. 93% of the bar is silver. how many ounces of silver are in the bar? (round to the nearest thousandth)

7.560 ounces

Step-by-step explanation:

Given : The weight of a metal bar = 8.15 ounces

Also, it is given that : 93% of the bar is silver.

We can write 93% as 0.93  [To convert percent into decimal or fraction , we divide it by 100.]

Now, the amount of silver in the metal bar = 93% of 5.15 ounces

Replace 'of' by '×' and '93%' by '0.93' , we get

The amount of silver in the metal bar =

Hence, there are 7.560 ounces of silver in the metal bar.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
