Answer:
Silver
Step-by-step explanation:
Find the volume of the coin
<u>Volume of a cylinder</u>
Given:
Substituting given values into the formula to find the volume:
Find the density of the coin given it has a measured mass of 18.54 g
<u>Density formula</u>
where:
= density- m = mass
- V = volume
Given:
- m = 18.54 g
Substituting given values into the density formula:
Given:
Therefore, as 
the coin is made from silver.
Answer:
D. 5(x^2+5)
Step-by-step explanation:
5x^2+25
Viewing the two terms 5 is divisible by both
5X^2/5 +25/5
X^2+5
Therefore the equation will be represented by
5(x^2+5)
The 30% off is $82.50 cheaper. Which would be $192.50
I think the coordinates are 1, 10 but not positive because if you graph it you can see a kite in it so make the point close to 4,10
Answer:
y = -17/2
Step-by-step explanation:
Substitute with the givens.
30= 8(8) + 4y.
Multiply parentheses.
30 = 64 + 4y
Subtract.
30-64= -34
-34 = 4y.
Divide each side by 4.
y = - 8.5, or -17/2
hope that is right!
