Step-by-step explanation:
Let x be the total allowance of fat
16 grams is 80% of his total allowance
x * 80% = 16

.8x/.8 = 16/.8
x = 20
Answer:
126 in.³
Step-by-step explanation:
Volume of a rectangle/square is length x width x height so you just multiply all the dimensions together.
Hope this helped :)

take the derivitive to find the slope


so at x=1, the slope is f'(1)=6(1)^2-4=6-4=2
y=mx+b
y=2x+b
find b
at x=1, f(1)=2(1)^3-4(1)=2-4=-2=y
-2=2(1)+b
-2=2+b
-4=b
equation is y=2x-4
Answer:
B

Answer:
How much would it cost to buy 10 pounds of peanuts?
Answer: $35
What is the cost per pound?
Answer: $3.50
Step-by-step explanation:
So first, to find the anser to the first question, we need to find out the second question. So, what is the cost per pound.
Well if she got 4 pounds for $14, we should try dividing 14 by 4.
14 divided by 4 = 3.5 ($3.50)
So the cost per pound is $3.50
Now to find out how much it costs if Lulu bought 10 pounds, we need to multiply.
10 x 3.5 = 35
So if she bought 10 pounds, she would play $35
