Step-by-step explanation:
The number of cups of milk would be 2 2/3 needed in the four milkshakes.
<h3>What is Ratio?</h3>
A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
We have been given that martin is making four milkshakes. The recipe calls for 2/3 cup of milk.
We have to determine the number of cups of milk he needs
Let the number of cups of milk would be x in the four milkshakes.
As per the given situation, we can write the ratio would be as:
1 milkshakes : 2/3 cup of milk = 4 milkshakes : x cup of milk
⇒ 1 / (2/3) = 4/x
Reciprocal the term in the numerator,
⇒ 3/2 = 4/x
Apply the cross-multiplication operation,
⇒ 3x = 8
⇒ x = 8/3
⇒ x = 2 2/3
Thus, the number of cups of milk would be 2 2/3 in the four milkshakes.

Answer:
a). total length of rope=132 m
b). total cost of the rope=$528
Step-by-step explanation:
Step 1
To get the total length of rope needed to cover the circular garden twice, we express this as;
P=πD
where;
P=perimeter
π=pi
D=diameter
In our case;
π=22/7
D=21 m
replacing;
P=(22/7)×21=66 m
2×P=2×66=132 m
total length of rope=132 m
Step 2
The expression to calculate the total cost can be written as;
total cost=cost per meter length×total length of rope
where;
cost per meter=$4
total length of rope=132 m
replacing;
total cost=4×132=$528
total cost of the rope=$528
