Miguel needs 4 gallons of milk to make 12 milkshakes. How much milk does he need to

horrorfan [7]

Answer:

see the procedure

Step-by-step explanation:

Part 1) using proportion

we know that

Miguel needs 4 gallons of milk to make 12 milkshakes

Using proportion

Find out how much milk he needs to make 30 milkshakes

Let

x ----> gallons of milk needed

$\frac{4}{12}\frac{gal}{milkshakes}=\frac{x}{30}\frac{gal}{milkshakes}\\\\x=30(4)/12\\\\x=10\ gal$

Miguel needs 10 gallons of milk to make 30 milkshakes

Part 2) we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

This problem represent a proportional relationship

Let

x ----> the number of gallons of milk

y ----> the number of milkshakes

we know that

Miguel needs 4 gallons of milk to make 12 milkshakes

For x=4, y=12

Find out the constant of proportionality k

$k=y/x$

substitute the values

$k=12/4=3\ milkshakes/gallon$

The linear equation is equal to

$y=3x$

For y=30

substitute in the equation and solve for x

$30=3x$

Divide by 3 both sides

$x=10\ gal$

Which expression is equivalent to

enot [183]

Answer:

The correct answer is last option

x¹⁶y²²

Step-by-step explanation:

Points to remember

Identities

Xᵃ * Xᵇ = X⁽ᵃ ⁺ ᵇ⁾

Xᵃ/Xᵇ = X⁽ᵃ ⁻ ᵇ⁾

(Xᵃ)ᵇ = Xᵃᵇ

To find the correct answer 

It is given an expression {X⁶Y⁸}³/X²Y²

By using identities we can write,

{X⁶Y⁸}³/X²Y² = X⁶ˣ³ Y⁸ˣ³/X²Y²

= X¹⁸Y²⁴/X²Y²

= X⁽¹⁸ ⁻ ²⁾ * Y⁽²⁴ ⁻ ²⁾

= X¹⁶Y²²

Therefore the correct answer is last optionX¹⁶Y²²
