gradient of L = -7/4

Explanation:

\sf gradient = \dfrac{y_2-y_1}{x_2-x_1}

<u>Insert the following values.</u>

\rightarrow \sf \dfrac{2-(-5)}{1-5}

\rightarrow \sf \dfrac{7}{-4}

\rightarrow \sf -\dfrac{7}{4}

<h3>hello!</h3>

Use the slope formula:-

(the slope is the same as the gradient)

\sf{\displaystyle\frac{y2-y1}{x2-x1} }

\sf{\displaystyle\frac{2-(-5)}{1-5}}

\sf{\displaystyle\frac{2+5}{-4} }=\frac{7}{-4} ={\boxed{-\frac{7}{4} }}\leftarrow\sf{slope~of~line~L}}}

<h3>note:-</h3>

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

By using the concept of uniform rectilinear motion, the distance surplus of the average race car is equal to 3 / 4 miles. (Right choice: A)

<h3>How many more distance does the average race car travels than the average consumer car?</h3>

In accordance with the statement, both the average consumer car and the average race car travel at constant speed (v), in miles per hour. The distance traveled by the vehicle (s), in miles, is equal to the product of the speed and time (t), in hours. The distance surplus (s'), in miles, done by the average race car is determined by the following expression:

s' = (v' - v) · t

Where:

  • v' - Speed of the average race car, in miles per hour.
  • v - Speed of the average consumer car, in miles per hour.
  • t - Time, in hours.

Please notice that a hour equal 3600 seconds. If we know that v' = 210 mi / h, v = 120 mi / h and t = 30 / 3600 h, then the distance surplus of the average race car is:

s' = (210 - 120) · (30 / 3600)

s' = 3 / 4 mi

The distance surplus of the average race car is equal to 3 / 4 miles.

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number
professor190 [17]

<u>Answer:</u>

<em>Number of calories in one slice of a 14 inch pizza is 189.825. </em>

<u>Step-by-step explanation:</u>

Given that 6 inch pizza has <em>650 calories. </em>

Therefore 1 inch pizza has \frac{650}{6} <em>calories. </em>

14 inch pizza will have  

\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

<em>\frac {1516.66}{8} =189.825 calories</em>
