Answer:

9.8

Step-by-step explanation:

The crew worked for 4 1/5 days

They built 2 1/3 kilometres of road each day

Therefore the total length of the road can be calculated as follows

= 4 1/5 × 2 1/3

= 21/5 × 7/3

= 147/15

= 9.8

Hence the length of the road is 9.8 kilometres

Which inequality represents the sentence below? The difference of a number and one and four tenths is more than nine and seventy
Marianna [84]

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

  • Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
  • Hundredths is written as the fractional part of the number 100. The value of one hundredth is equal to 1/100 or 0.01.

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

1\dfrac{4}{10}

Nine and seventy-eight hundredths can be written as,

9\dfrac{78}{100}

Let suppose the number is <em>p</em>. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\

Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

PLEASE HELP FOR BASKETBALL EINSTEINE
Karo-lina-s [1.5K]
The constant term in the given equation is -3. This is the point where the graph must cross the y-axis. Graph B crosses at +3, so is not the answer.

The coefficient of x is 3/4. This means the line rises 3 units in 4 horizontal units. The line in Graph C appears to rise 3 units in 2 horizontal units, so is not the answer.

Graph A has the correct y-intercept and slope, so is the correct choice.
