A racing car used 255 litres of fuel to complete

1 answer:

5 0

To answer thie question, you must first develop a proportional statement that compares the liters of fuel used to the distance driven. Considering the subject matter of your question, said statement should be formatted like this:

(255L/340km)=(x/100)

Since this is a proportional statement, you can scale up or down the relative unit to complete the statement. In this case, you will be solving for liters, represented by x, so solve the statement using a ratio for the other side of the equation, in this case the denominators:

340/100

You should get 3.4. That is what you will be scaling the other unit with. Now it is a simple matter to substitute for the numerators:

255/3.4=x

After solving this equation, your final answer should be x=75.

Hope that helps.

What is the 385/6 as a proper fraction

Effectus [21]

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 385 by 6 and keep only what is to the left of the decimal point:

385 / 6 = 64.1667 = 64

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

385 - (6 x 64) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 385/6 as a mixed number is:

64 1

Consider the table of values.

Anestetic [448]

Answer:

B. The relationship between the variables in the table is quadratic because the second differences are constant.

Step-by-step explanation:

We have to look for the differences in the y values of the given table.

The y values are:

0, 2, 6, 12, 20, 30, 42

The differences between the consecutive values are:

2, 4, 6, 8, 10, 12

These are the first differences and are not constant. This means the relationship is not linear. Now we again find the differences between the consecutive values:

2, 2, 2, 2, 2

These are the second differences. The second differences are constant. So this means the given relationship is quadratic.

Therefore, option B gives the correct answer. The relationship between the variables in the table is quadratic because the second differences are constant.
