martin is making four milkshakes if the recipe calls for 2/3 cup of milk how many cups of milk does he need
Bogdan [553]

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.

A gardener wants to fence a circular garden of diameter 21 m. Find the length of the rope he needs to purchase, if he makes 2 ro
djyliett [7]

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
