Bronze which costs $7.05/kg is made by
combining copper which costs $6.20/kg with
tin which costs $8.70/kg. Find the number of
kg of copper and tin required to make 5 kg of
bronze.
Find the number of kg of copper and tin required to make 15.3 kg of bronze. (NO LINKS)
Answer: 3.3 kg of Cu, 1.7kg of Sn
I abbreviate copper as Cu and tin as Sn.
Step-by-step explanation:
For 5 kg of $7.05$/kg bronze: Let x be the mass of Cu. The mass of Sn would be 5-x.
Multiply these two masses by their respective element cost.
Cu = ($6.20/kg)x [The total value of copper in 5 kg of bronze]
Sn = ($8.70/kg)(5-x) [The total value of tin in 5 kg of bronze]
We know that:
($6.20/kg)x + ($8.70/kg)(5-x) = $7.05
Solve for x. I get
x= 3.3 kg of Cu
5-x = 1.7kg of Sn
==
Check the result for 5 kg of bronze:
(3.3 kg of Cu)*($6.20/kg) = $20.46 cost of Cu
(1.7kg of Sn)*($8.70/kg) = $14.79 cost of Sn
Thus, the total cost for 5kg of bronze is $35.25. That makes it $7.05/kg.

Answer:
≈ 404 m²Step-by-step explanation:
Volume of a sphere:
V = 4/3πr³LSA = TSA of a sphere:
S = 4πr²We have V = 764 m³, find the radius:
4/3πr³ = 764r³ = (3*764/4π)r³ = 182.39 (rounded)r = √182.39r = 5.67 m (rounded)Find the surface area:
S = 4*π*(5.67)²S = 404 m² (rounded)[tex] \boxed{\tt{ \bold{Hello\:Mister\:Brainly!}}}[/tex]
____________
Step by step :S = 4πr²
S = 4π × (V = 4/3πr³)²
S = 4π × (764 = 4/3 × 3,14 × r³)²
S = 4π × (764 × 3/4 = 3,14r³)²
S = 4π × (573 ÷ 3,14 = r³)²
S = 4π × (r³ ≈ 182,5)²
S = 4π × (r ≈ 5,67)²
S = 4 × 3,14 × 5,67²
S ≈ 404m²✔

Answer:

[tex]15 \times x = 200 \\ 15x = 200 \\ x = 200 \div 15 \\ x = \frac{40}{3} [/tex]
The painter should work at least 13.33 hours to earn $200.
What is inequality?An inequality is a mathematical statement showing the non-equal comparison between two expressions.
Given that, a painter earns $15 per hour. We need to find the minimum number of hours he must work to earn at least $200,
So, let the minimum number of hours be x,
15x ≥ 200
This will be the inequality,
To find the minimum number of hours we will find the value of x,
15x ≥ 200
Divide by 15
x ≥ 200/15
x ≥ 13.33
Hence, the painter should work at least 13.33 hours to earn $200.

Which of the following does not represent a function?
Answer:
i think it's C sorry if it's wrong
Step-by-step explanation:
i took the test and got it right so
Answer:
The third option
Step-by-step explanation:
1. To determine whether a relation is a function given a graph, use the
following criterion:
if every vertical line you can draw goes though only 1 point, then the relation is a function If you can draw a vertical line that goes though 2 or more points, y is not a function of x. This is called the vertical line test.2. As you can see, if you draw a vertical line at a specific place in the third graph, it will go through 2 or more points.
Therefore, the correct answer is the third option/graph.

Answer:
$25 = $6.50d
Step-by-step explanation:
Since d represents the amount of boxes of donuts, you would need to multiply d in the equation by 6.5 or $6.50 since the problem states that 1 dozen donuts costs $6.50 (assuming 1 box contains 1 dozen donuts). $6.50d would have to equate or equal to $25 because the equation 25 = 6.5d shows the most amount of boxes of donuts Tucker could purchase with $25.
If you were wondering, Tucker could purchase up to 3 boxes donuts with $25.
Answer:
cost of 1 box = $6.50
total money =$25
he want $26 to buy 4 boxes
