270/15 = 135/ 7.5
cross multiply to see if it is a true proportion
(15)(135) = (270)(7.5)
2025 = 2025 (correct...so this is a true proportion)

answer is : bottom right one

Answer:

last fourth table given in the figure shows the proportional relationship .

Step-by-step explanation:

Definition of proportional relationship

The relationship in which two quantities are varies proportional to each other .

a = kb

Where k is called the proportional constant .

Let us assume that the number of miles travelled be y .

let us assume that the gas used be x .

y\propto x

y = ca

Where c is the proportional constant .

In first table

Miles travelled = 27.3 mi

Gas used =1.5 gal

Putting in the formula

y = ca  

27.3 = 1.5c

\frac{27.3}{1.5}=c

c = 18.2

Miles travelled = 49.16 mi

Gas used = 3.8 gal

Putting in the formula

y = ca  

49.16 = 3.8c

\frac{49.16}{3.8}=c

c = 12.94 (Approx)

Thus the miles travelled is not vary with the gas used .

Therefore table not shows the proportional relationship .

Second Part

Miles travelled = 135 mi

Gas used = 7.4 gal

Putting in the formula

y = ca  

135 = 7.4c

\frac{135}{7.4}=c

c = 18.2

Miles travelled = 135.5 mi

Gas used = 7.9 gal

Putting in the formula

y = ca  

135.5 = 7.9c

\frac{135.5}{7.9}=c

c = 17.2 (Approx)

Thus the miles travelled is not vary with the gas used .

Therefore table not shows the proportional relationship .

Third table

Miles travelled = 120 mi

Gas used = 6.2 gal

Putting in the formula

y = ca  

120 = 6.2c

\frac{120}{6.2}=c

c = 19.4 (Approx)

Miles travelled = 180 mi

Gas used = 12.2 gal

Putting in the formula

y = ca  

180 = 12.2c

\frac{180}{12.2}=c

c = 14.8 (Approx)

Thus the miles travelled is not vary with the gas used .

Therefore table not shows the proportional relationship .

Fourth table

Miles travelled = 270 mi

Gas used = 15gal

Putting in the formula

y = ca  

270 = 15c

\frac{270}{15}=c

c = 18

Miles travelled = 135 mi

Gas used = 7.5 gal

Putting in the formula

y = ca  

135= 7.5c

\frac{135}{7.5}=c

c = 18

Thus the miles travelled is vary with the gas used .

Therefore table shows the proportional relationship .

The last fourth table given in the figure shows the proportional relationship .

The can is 12cm high and 8cm in diameter. Using formula V=TT r2h, how much is in the can
scoray [572]
The formula you have given here is for the volume of a cylinder. It should read V =  \pi r^{2} h.
First, to find r, the radius, divide the diameter by two (since the radius is the distance from the circumference to the centre and the diameter is the distance from any point on the circumference to the opposite point (through the centre))

r = 8/2 = 4

Now we can calculate this.
V =  \pi *4^{2}*12 =  \pi * 16 * 12 = 603.185... \\ 
V = 603 cm^{3}

If your answer needs to be in litres, one cubic centimetre = one millilitre.

603 cm3 = 603mL = 0.603 L

PLEASE HELP!! Trevor is writing a paper that must be 50,000 words long. He had already written 23,210 words. Write an inequality
almond37 [142]

Answer:

50,000 ≤ 23,210 + 5x

x = Average number of words per week

Step-by-step explanation:

Start off with 50,000 because that's how many words the paper needs to have.

Use "≤" because Trevor needs to write at least 50,000 words. (He can write more).

Trevor already wrote 23,210 words plus x words per week for 5 weeks.

(Solving for x will help you find the average number of words Trevor must write per week for 5 weeks).

Answer:

  (-3, 9), (-1, 11), (0, 12), (4, 16), (6, 18)

Step-by-step explanation:

The function definition tells you that adding 12 to the x-value will give you the value of f(x).

  -3 +12 = 9, for example

The (x, f(x)) values for the table are shown above.
