The pyrite cube is, well, a cube, so it has a side length <em>s</em> such that the area of its base is
<em>s</em> ² = 5.76 cm²
which means
<em>s</em> = √(5.76 cm²) = 2.4 cm
Then its volume is
<em>s</em> ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
Answer:
u = (-21)/20
Step-by-step explanation:
Solve for u:
u + 1/4 = (-4)/5
Put each term in u + 1/4 over the common denominator 4: u + 1/4 = (4 u)/4 + 1/4:
(4 u)/4 + 1/4 = -4/5
(4 u)/4 + 1/4 = (4 u + 1)/4:
1/4 (4 u + 1) = -4/5
Multiply both sides of (4 u + 1)/4 = (-4)/5 by 4:
(4 (4 u + 1))/4 = (-4)/5×4
4×(-4)/5 = (4 (-4))/5:
(4 (4 u + 1))/4 = (-4×4)/5
(4 (4 u + 1))/4 = 4/4×(4 u + 1) = 4 u + 1:
4 u + 1 = (-4×4)/5
4 (-4) = -16:
4 u + 1 = (-16)/5
Subtract 1 from both sides:
4 u + (1 - 1) = (-16)/5 - 1
1 - 1 = 0:
4 u = (-16)/5 - 1
Put (-16)/5 - 1 over the common denominator 5. (-16)/5 - 1 = (-16)/5 - 5/5:
4 u = (-16)/5 - 5/5
-16/5 - 5/5 = (-16 - 5)/5:
4 u = (-16 - 5)/5
-16 - 5 = -21:
4 u = (-21)/5
Divide both sides by 4:
u = ((-21)/4)/5
5×4 = 20:
Answer: u = (-21)/20
Answer:
It should be 785 feet if i did it right but im not sure how to do it
Step-by-step explanation:
Sorry if im wrong!
Hey there! :D
Find the slope first. (0,7) (1,8)
m= (y2-y1)/(x2-x1)
m= (8-7)/(1-0)
m= 1/1
m=1
Now, use those points in point slope form. (0,7) as the point.
y-y1= m(x-x1)
y-7= 1(x-0)
y-7= 1x-0
Add 7 to the other side.
y= 1x+7 <== that is in y=mx+b form
or y= x+7
I hope this helps!
