Based on the amount of cheese used for the pizzas, the following are true:
- a. Mai uses 2.5 ounces of cheese per pizza.
- b. Mai will need 37.5 ounces for 15 pizzas.
<h3>Cheese used per Pizza. </h3>
This can be found as:
= Ounces of cheese used / Number of pizzas
= 10 / 4
= 2.5 ounces per pizza.
<h3 /><h3>Cheese needed for 15 pizzas. </h3>
= Number of pizzas x Cheese per pizza
= 15 x 2.5
= 37.5 ounces of cheese.
In conclusion, Mai needs 37.5 ounces of cheese to make 15 pizzas.

The mass of the acetic acid is 1.512 g.
<h3 /><h3>What is Molarity?</h3>
molarity is the concentration of a substance in mol per dm³
From the question,
The number of moles contained in the 30 mL vinegar is
- n = (0.84×30)/1000
- n = 0.0252 mol.
the molar mass of vinegar is calculated below.
- m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
- m.m = (1+24+3+32]
- m.m = 60 g/mol.
To calculate the mass of acetic acid, we use the formula below.
- R.m = n×m.m............. Equation 1
Where
- R.m = mass of acetic acid.
Substitute these values into equation 1
- R.m = (0.0252×60)
- R.m = 1.512 g.
Hence, The mass of the acetic acid is 1.512 g.

The correct answer to what additional measurement the student requires is; D. The student has enough information to make the determination
<h3>Understanding Change in Momentum</h3>
Formula for change in momentum is;
ΔP = m(v - u)
Now, this change in momentum is also equal to impulse which has the formula; Impulse = Force(F) × Time(t)
I = F × t
Thus;
m(v - u) = F × t
Now, we are given;
Force exerted on the object and the time interval. Thus;
ΔP = F × t
Thus, the student has enough information to find the change in momentum
The missing options are;
a. The mass of the object.
b. The final speed of the object MOH 5000
c. The distance fallen by the object
d. The student has enough information to make the determination

Answer:
D. to earn an associate's degree
Explanation:
This is false because 4 year college usually means a bachelor's degree. An associate's degree is the degree you obtain after completing your first two years of a bachelor's degree.
