Boots=x
Shoes=x-15
3(x-15)+2x=120
3x-45+2=120
5x-45+2x=120
5x=165
X=33
Boots=$33
Answer:
6
Step-by-step explanation:
(-1^2 + -1-2) / (2*-1^2 + -2-3)
1 + -3 / 2 + -5
-2 / -3
= 6
Answer:
broad sense heritability = 0.75
Step-by-step explanation:
Step 1: Variables
phenotypic variation (Vp)
genotype variation (Vg)
environment variation (Ve)
broad sense heritability (H)
Step 2: Formulas:
H = Vg / Vp
Vp = Vg + Ve
Vg = Vp - Ve
Step 3: Given data
Vp = 20
Ve = 5
Step 4: Computation
Vg = 20 - 5 = 15
H = 15 / 20
H = 0.75
Hope this helps!
Answer:
5/8
You just have to multiply the bottom and the top then simplify
Answer:
4.5 inches
Step-by-step explanation:
We are given the formula:
V =
Plug in the the radius (3) and volume (127.23):
127.23 = 
Square the 3 :
127.23 = 
Multiply the pi & volume:
127.23 = 28.26h
Divide both sides by 28.26:
127.23 ÷ 28.26 = 28.26h ÷ 28.26
h = 4.5021231...
I hope this helps!
