You need to add up all 3 mixed numbers to find the total laps.

2 + 1/4 + 1 + 1/2 + 3 + 5/8 =

(2 + 1 + 3) + (1/4 + 1/2 + 5/8) =

6 + (2/8 + 4/8 + 5/8) =

6 + (11/8) =

6 + (1 + 3/8) =

7 3/8 laps

Answer: There are 7\dfrac{3}{8} laps in all.

Step-by-step explanation:

Since we have given that

Number of laps must run by first team = 2\dfrac{1}{4}=\dfrac{9}{4}

Number of laps must run by second team = 1\dfrac{1}{2}=\dfrac{3}{2}

Number of laps must run by third team = 3\dfrac{5}{8}=\dfrac{29}{8}

So, total number of laps in all must run is given by

\dfrac{9}{4}+\dfrac{3}{2}+\dfrac{29}{8}\\\\=\dfrac{18+12+29}{8}\\\\=\dfrac{59}{8}\\\\=7\dfrac{3}{8}

Hence, there are 7\dfrac{3}{8} laps in all.

= table shows a hot air balloon's height h, in feet, during a descent at various times t, in seconds.
denpristay [2]

Answer:

A. Slope is -12 feet per second

B. Yes, it is constant.

<u>Skills needed: Linear Equations, Substitution and Division</u>

Step-by-step explanation:

1) Solving Part A (we need to find the slope):

  • The slope is \frac{y_2-y_1}{x_2-x_1} --> y_1, y_2, x_1, and x_2 are all values from the table. We know that the left column is the x-values, and the right column is the y-values as that is the conventional way of depicting them.

2) Using the y-values of 1150 and 1090, and their corresponding x-values (5 and 10 respectively), we can get the slope:

- \frac{y_2-y_1}{x_2-x_1} ==> \frac{1090-1150}{10-5} ==> 1090-1150=-60, 10-5=5 ==> \frac{-60}{5}

\frac{-60}{5} =-12, so the slope is -12.

==================================================================

1) Part B (analysis)

We can see that no matter what 2 y-values and their corresponding x values we use, the slope always is the same. This means that the rate of change is constant.
