Answer:
$4.80
Step-by-step explanation:
Make a proportion
$12 for 2.5 pounds, and $x for 1 pound
12/2.5=x/1
x/1 is equivalent to x
12/2.5=x
Divide
x=4.8
So, one pound of peanuts costs $4.80
Answer:
The current price of the item is $600.
The price of the item 9 years from today will be of $756.
Step-by-step explanation:
Price of the item:
The price of the item, in dollars, after t years, is given by:
Current price of the item
This is p(0). So
The current price of the item is $600.
9 years from today.
This is p(9). So
The price of the item 9 years from today will be of $756.
Answer:
D., x= 19.7 or ≈20. g
Step-by-step explanation:
P(x) = [100(15+x)]/(100+x)
When 0 g additional salt is added, x=0. we have
P(0) = [100(15+0)]/(100+0)= 15
x=0, P=15
We can see this point only on the graph D.
P(x) =29 = [100(15+x)]/(100+x)
29 = [100(15+x)]/(100+x)
29(100+x) = 100(15+x)
2900+29x = 1500+100x
2900-1500=100x-29x
1400 = 71x
x ≈ 19.7 g or ≈20. g
From the graph D, we can see that to get 29% we need to add ≈ 20 g of salt.
Answer:
I dont know but example
Step-by-step explanation:
A cubic foot is a cube with a side length of one foot.
We know that, 1 foot = 12 inches.
So, 1 cubic foot is a cube with side length 12 inches.
You can use the formula for the volume of a prism, V=bwh , to convert cubic units.
Since 1 foot = 12 inches, replace b , w , and h with 12 .
V=(12)(12)(12) =1,728
So, 1 cubic foot is equal to 1,728 cubic inches.
