2 answers:
Answer: 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.

1. Since we are using direct substitution, the only thing we need to do is replace
by 
(the quantity is approaching to) in our quantity to get:
We can conclude that the correct answer is B) -6
2. Again, since we are using direct substitution, th only thing we need to do is replace by 
(the quantity x is approaching to) to get:
We can conclude that the correct answer is D) 31
3. Direct substitution again, so we are going to replace in our quantity by 
to get:
And since cosine of is 0, and any quantity multiplied by zero is zero:
We can conclude that the correct answer is A) 0
4. Here we need to so some algebra first. Notice that if we use direct substitution, the denominator will be zero, and we cannot divide by zero. So lets massage our quantity first:
Now, we can use direct substitution to get:
We can conclude that the correct answer is B) 4
