Question

HURRY!!! PLEASE HELP WITH QUESTIONS!!!! WILL MAKE BRAINIEST ANSWER!!!!

Answer 1

I would say the first one 3.30 and for 2.the 4th chart

Answer 2

Answer:

Part 1) option A $3.30\frac{\ }{gallon}$

Part 2) Table 3 see the attached figure

Step-by-step explanation:

Part 1)

we know that

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

The table represent a direct variation

The unit rate for one gallons of gasoline is equal to the constant of proportionality k

Let

x-----> the number of gallons

y-----> the price

so

For $x=2\ gallons$, $y=\ 6.60$

Find the value of k

$6.60/2=k$

$k=3.30\frac{\ }{gallon}$

Part 2)

Let

x------> string instruments

y------>  percussion instruments

$ratio=\frac{x}{y}$

table 1

the ratio is equal to

$ratio=\frac{2}{3}$

table 2

the ratio is equal to

$ratio=\frac{2}{5}$

table 3

the ratio is equal to

$ratio=\frac{2}{1}=2$

table 4

the ratio is equal to

$ratio=\frac{2}{4}=\frac{1}{2}$
