First find the total by adding the 3 amounts together:
25.50 + 32.15 + 15.25 = $72.90 total.
Now divide the total by the number of people:
72.90 / 5 = 14.58
Each person needs to pay $14.58
Answer:
36
Step-by-step explanation:
Work out the terms inside the parenthesis from x = 2 to x = 5. Hint: there will be 4 terms.
x = 2 ---> 0
x = 3 ---> 1
x = 4 ---> 2
x = 5 ---> 3
The sigma symbol means that you have to add them all up so the sum is 6. Therefore,
(6)^2 = 36
The constant speed, or "average rate of change" is their slope.
so hmmm looking at Fred's graph, let's pick two points on the line, say 0,0 the origin and 8,2
![\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 0}}\quad ,&{{ 0}})\quad % (c,d) &({{8}}\quad ,&{{ 2}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{2-0}{8-0}\implies \cfrac{2}{8}\implies \cfrac{1}{4}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Blllll%7D%0A%26x_1%26y_1%26x_2%26y_2%5C%5C%0A%25%20%20%20%28a%2Cb%29%0A%26%28%7B%7B%200%7D%7D%5Cquad%20%2C%26%7B%7B%200%7D%7D%29%5Cquad%20%0A%25%20%20%20%28c%2Cd%29%0A%26%28%7B%7B8%7D%7D%5Cquad%20%2C%26%7B%7B%202%7D%7D%29%0A%5Cend%7Barray%7D%0A%5C%5C%5C%5C%5C%5C%0A%25%20slope%20%20%3D%20m%0Aslope%20%3D%20%7B%7B%20m%7D%7D%3D%20%5Ccfrac%7Brise%7D%7Brun%7D%20%5Cimplies%20%0A%5Ccfrac%7B%7B%7B%20y_2%7D%7D-%7B%7B%20y_1%7D%7D%7D%7B%7B%7B%20x_2%7D%7D-%7B%7B%20x_1%7D%7D%7D%5Cimplies%20%5Ccfrac%7B2-0%7D%7B8-0%7D%5Cimplies%20%5Ccfrac%7B2%7D%7B8%7D%5Cimplies%20%5Ccfrac%7B1%7D%7B4%7D)
now, for Sam, let's use the last two points in the table then,
Answer:
1. 1 cm
2. 7 and 2/16 (or 1/8) inches
Step-by-step explanation:
