The u. s. penny has a diameter of 1.905 cm. the densities of copper and zinc are
8.96 g/cm3 and 7.14 g/cm3, respectively.
a. between 1944 and 1982, the penny was made of a brass alloy that is 95% copper and 5% zinc by mass. if the mass of the penny was 3.09 g, find the volume (in cm3) and thickness (in cm) of the penny in mm. (assume the penny is a cylinder, v = πr^2h)

answer:

1? idk im dumb : (

explanation:

answer:

2

explanation:

1+1 = 2

the reason this is so is because of basic addition. we can double check this without using addition if you really want. if you take 1+1=x, subtract 1 from both sides than you get 1 = x - 1. subtract x from both sides and you get 1 - x = -1. subtract 1 from both sides again and you get -x = -2. finally, multiply both sides by -1 to get x = 2. subtraction is still technically addition you say? fine, have it your way. 1 + 1 = x. by definition, adding something to itself is the same thing as multiplying it by 2. this means we can technically rewrite the equation as

1 * 2 = x. now all we have to do is solve it. 1 * 2 = x when simplified results in 2 = x, or x = 2. this shows 1 + 1 = x. you say you want a real answer. you want me to start you from the ground up? well i would, but that would practically just be stealing from what was written on this website: go check it out if you really need to.

dude i am uh almost professional guitar player what do you probably work at burger
