Answer: Yes

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

Step-by-step explanation:

The total cost of the apples is proportional to the total mass. The product of the mass and the cost per mass ($3.12) gives the total cost.

It can be shown using the equation below

Tc = c×m

Where Tc = total cost

c = cost per unit mass

m = total mass in kilogram

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

Answer:

○ b Parallel

Step-by-step explanation:

If you take a look at each group of coefficients [2x and 5y, 4x and 10y], they have a proportional relationship, so when converting from Linear Standard Form to Slope-Intercept Form, they will always have an exact same rate of change [slope] of −⅖.

Answer:

86 degrees farenheit

Step-by-step explanation:

First, we plug 30 in for C.

Next, solve for F

Multiplying both sides by 9/5 gives us 54=F-32

Add 32 to both sides 86=F
