2kg of coconut juice, which costs $5/kg, were combined with 8kg of coconut milk, which costs $3/kg. Find the cost per kg of the

katen-ka-za [31]

Cost per kg=(total cost)/(total kg)

total cost
coconut juice: 2kg, at $5/kg, so 5*2=$10
coconut milk: 8kg, at $3/kb, so 8*3=$24

total cost=10+24=$34

total kg=2+8=10

cost per kg=$34/10kg=$3.40per kg

The precooked weight of a hamburger is 0.25 pounds. Convert this mass to centigrams (cg). (1lb = 16oz, 16oz = 454g)

blsea [12.9K]

.25 lbs= 4oz
4oz = 113.398 g
1g= 100cg

113.398 x 100

The first rule you need to know is

$(a^b)^c=a^{bc}$

So, you have

$\dfrac{(x^{25})^{-6}}{(x^{-3})^{48}}=\dfrac{x^{25\cdot(-6)}}{x^{-3\cdot 48}}=\dfrac{x^{-150}}{x^{-144}}$

The second rule you need to know is

$\dfrac{a^b}{a^c}=a^{b-c}$

So, you have

$\dfrac{x^{-150}}{x^{-144}}=x^{-150-(-144)}=x^{-150+144}=x^{-6}$
