Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4
It adds .8 for every 1 so it would be 6.2 and 7
Answer:
8.3 cm
Step-by-step explanation:
So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.
Perimeter (P) = s+s+s+s+s (sides)
P: 41.5 cm ÷ 5 =
8.3 cm
We know this is correct because:
8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5
Hope this helps!
Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so
xy=15000
x+y=5
x+y=5
y=5-x
x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x=

x^2-5x+15000
a=1
b=-5
c=15000
x=

x=

x=

x=

so the numbers are

and
Let x = number of cans
let c = cost
c = .70x
