Answer: The volume is 288π .
Step-by-step explanation:
V= 4/3 *n*r^3
V = 4/3*n * 6^3
v=4/3 *n * 216
v= 288n
Step-by-step explanation:
The constant of proportionality is the ratio of the cost to the number of pounds of walnuts. In other words, it is the price of one pound of walnuts.
$10.92 / 4 lb = $2.73 / lb
Answer:
incorrect
Step-by-step explanation:
the volume of a cube = s³ ( where s is the length of the side )
to find s take the cube root
s =
= 3
since 3 × 3 × 3 = 27
Answer:
A. Total number of liters = 1.25 liters
B. Milk = 0.25 liters
Step-by-step explanation:
Let
x = total number of liters ( milk + water )
Milk = 20% of x
= 0.2x
Water = 1 liter
Total number of liters = milk + water
x = 0.2x + 1
x - 0.2x = 1
0.8x = 1
Divide both sides by 0.8
x = 1 / 0.8
= 1.25
x = 1.25 liters
Total number of liters = 1.25 liters
B.
Liters of milk in the bottle = Total number of liters - liters of water
= 1.25 liters - 1 liter
= 0.25 liter
Milk = 0.25 liters
Answer:
(1
, 2
)
Step-by-step explanation:
Given the 2 equations
7x - y = 7 → (1)
x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
14x - 2y = 14 → (3)
Add (2) and (3) term by term to eliminate y
15x = 20 ( divide both sides by 15 )
x =
=
= 1 
Substitute this value of x into either of the 2 equations and solve for y
Substituting in (2)
+ 2y = 6
2y = 6 -
=
( divide both sides by 2 )
y =
= 2
