Answer:
a. $1.40
b. $8.40
c. 15 lbs
that's all i know but i hope this helps!
A=PIEr^2, letting r=14
a=PIE(14)^2
=615.75ft^2
use the symbol pie as the substitution for the actual word
Answer:
Step-by-step explanation:
we have the mean=13
(x+y+z)/3=13
x+y+z=39
range=highest value-lowest value=10
lets say x= highest value
y=lowest value
x-y=10
x=10+y
the numbers are 9,11,19
19-9=10 range
sum is 39
Answer:
Perimeter = 90
Step-by-step explanation:
Let c = hypotenuse, 15 = b, and a = other leg
Given: c/a = 13/12, so a = 12c/13.
c^2 = b^2+a^2
Using Pythagorean Theorem: c^2 = 225 + 144c^2/169.
169c^2 = 169(225) + 144c^2
25c^2 = 169(225)
5c = 13(15)
c = 13(3) = 39.
and a = 12*39/13 = 12*3 = 36
You now can compute all three sides, and
thus obtain perimeter = 36+39+15 = 90.
