The answer is 172.8 g.
The volume of the cube (V) is:
V = a³ (a - the side of the cube)
The density (D) <span>is quotient of mass (m) and volume (V):
D = m/V = m/a</span>³
⇒ m = D · a³
<span>
It is given:
D = 2.7 g/cm</span>³
a = 4 cm
Therefore:
m = D · a³ = 2.7 · 4³ = 172.8 g
2x + 5y = 10
Change to y = mx + b
subtract 2x from both sides
5y = -2x + 10
divide both sides by 5
y = -2/5x + 2
slope = -2/5
LETTER B
Answer:
(y-b) /x = m
Step-by-step explanation:
y = mx+b
Subtract b from each side
y -b = mx+b-b
y-b = mx
Divide each side by x
(y-b) /x = mx/x
(y-b) /x = m
Answer:
The correct option is B) 0.8x
Step-by-step explanation:
Consider the provided information.
Nancy is buying a new pair of boots. The store is having a sale and all boots are 20% off.
Let the original price is represented by x.
After getting 20% off the amount need to pay is:
Sale price = x-20% of x
Hence, the sales price of the boots is 0.8x.
Thus, the correct option is B) 0.8x
