One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 60 calories from p grams of protein an
nikitadnepr [17]

Answer:

1.5 grams of protein.

Step-by-step explanation:

The equation that represents the relationship between protein and fat is as follows :

4p + 9f = 60 ....(1)

We need to find the grams of protein are there if there are 6 grams of fat in the snack.

Put f = 6 in the above equation (1).

4p + 9(6)= 60

4p + 54 = 60

Subtract 54 to the both sides,

4p + 54-54 = 60-54

4p = 6

⇒ p = 1.5 grams

It means the snack contains 1.5 grams of protein.

To find the distance between two coordinates on a graph, use the Distance Formula: D = √((x₁ - x₂)² + (y₁ - y₂)²).

Our values for x₁, x₂, y₁, and y₂ will be replaced with the x- and y-values in the given coordinates, (5, 6) and (-4, -7).

Substitute.

√((x₁ - x₂)² + (y₁ - y₂)²)

√((-4 - 5)² + (-7 - 6)²)

Subtract.

√(-9² + (-13)²)

Square.

√(81 + 169)

Add.

√(250)

Simplify.

√(5² · 5 · 2)

√(5²)√(2 · 5)

5√(10) or approx 15.8114

Answer:

B. 15.81 units
