Answer:

d 17%

Step-by-step explanation:

I know this because you need to set a proportion determine the amount of fuel tax from the price paid. Replace the words in the proportion with the amounts you know. Then cross multiply. Divide both equations by $240

Answer:

17%

Step-by-step explanation:

Cost of fuel tax will be $280.8-$240=$40.8 and that is tge difference between the total payable amount and the basic cost.

Percentage of fuel tax in relation to the basic cost will be \frac {40.8}{240}\times 100=17

Therefore, this is equivalent to 17%

the graph of a line in the xy-plane has slope of 7 and contains the point(6,28). A second line passes through the points (3,7) a
Maslowich

Answer:

x = 3

Step-by-step explanation:

We require the equations of the 2 lines.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

The line has slope = 7, hence

y = 7x + c ← is the partial equation

To find c substitute (6, 28) into the partial equation

28 = 42 + c ⇒ c = 28 - 42 = - 14

y = 7x - 14 → (1)

Calculate the slope of the second line using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 7) and (x₂, y₂ ) = (- 1, - 13)

m = \frac{-13-7}{- 1-3} = \frac{-20}{-4} = 5, thus

y = 5x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 7), then

7 = 15 + c ⇒ c = 7 - 15 = - 8

y = 5x - 8 → (2)

Solving (1) and (2) by equating the right sides

7x - 14 = 5x - 8 ( subtract 5x from both sides )

2x - 14 = - 8 ( add 14 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

The x- coordinate of the point of intersection is x = 3

When working in the GreenHab, it takes me 120 minutes to report 20 tomato plants. How many plants can I report in 30 minutes?
Lyrx [107]

Answer:

Numbers of Tomato plants to be reported in 30 minutes = 5 unit

Step-by-step explanation:

It is given that ,

Time taken to report 20 Tomato plants (P1) = 120 minutes (T1)

Let number of plants to be reported in 30 minutes (T2) = P2

Now , \frac{T2}{P2} = \frac{T1}{P1}

          \frac{30}{P2} = \frac{120}{20}

So, P2 = 5 unit

Hence the number of plant to be reported in 30 minutes = 5 unit   Answer

How to find the length of EF?
nika2105 [10]

CD = \frac{HG + EF}{2} \Leftrightarrow EF = 2CD - HG

2x - 2 = 2x - x + 3\\2x - 2x + x = 3 + 2\\x = 5

EF = 2 * 5 - 2 = 10 - 2 = 8

Answer: 8.
