Answer:
144 carrots
Step-by-step explanation:
Let C stand for the number of carrots that a student can plant.
We are told that carrots may be planted at a density of 9 carrots/ft^2.
Let A be the area, in ft^2, that can be planted with carrots. The area of a rectangle is Base x Length (in feet).
We can therefore write:
C = (9 carrots/ft^2)*A
In the garden shown, the area is A = (4 ft) x (4 ft) = 16 ft^2
C = 9 carrots/ft^2)*(16 ft^2)
C = 144 carrots
Answer:
no
Step-by-step explanation:
A polynomial has no variables in any denominator. The exponent of any variable is a positive integer. This function is not a polynomial.
28% of 18.99 is 5.2172
Because 18.99 * 0.28 = 5.2172 which can be rounded to 5.22
So Gio would save about $5.22.
Answer:
Step-by-step explanation:
Solve the following equation for x:
Cost of 12 notebooks = $9
Ratio of number of notebooks to its price
= 12:9
= 4:3 <em>(because we reduced it to the simplest form by dividing both numerator and denominator by 3)</em>
Let the cost of 8 notebooks be x.
Then, 8:x = 4:3
=> 8/x = 4/3
=> (8×3)/4 = x
=> 24/4 = x
=> 6 = x
So, the cost of 8 notebooks is $6.
