Answer:
The dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.
Step-by-step explanation:
Since an artist combines copper and other metals to make bronze, and a bronze sculpture of a dolphin contains 43 g of copper for every 7 g of other metals, while a bronze sculpture of a bird contains 83 g of copper for every 17 g of other metals, to determine which sculpture is more coppery the following calculation must be performed:
Dolphin:
43 + 7 = 50
50 = 100
43 = X
43 x 100/50 = X
86 = X
Bird:
83 + 17 = 100
100 = 100
83 = X
83 x 100/100 = X
83 = X
Therefore, the dolphin statue is 86% copper, while the bird statue is 83% copper, making the dolphin sculpture more coppery.
Answer:
46 is the answer.
Step-by-step explanation:
12/(2) + 10(2)(4)/2
= 12/(2) + 80/2
= 6 + 40
= 46
Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",
Let,
- The amount invested in treasury note will be = x
- The amount invested in bond will be = (x + 3000)
then,
→ 
→

Pretty sure it’s the first answer
This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded
<h3>Inequality expression</h3>
Inequalities are equation not separated by an equal sign
Given the inequality expression
4x − 5 ≤ 19
4x ≤ 19 + 5
4x ≤ 24
x≤ 6
This solution shows that 6 is included in the solution due to the equal sign and not true for the inequality 4x − 5 < 19 since 6 is excluded
Given the equation
4x + 3 = 23
4x = 23 - 3
4x =20
x = 5
Hence 5 is the solution from the given set
