Tresset [83]

Answer:

D. 3 1/12

Explanation:

\rightarrow \sf 4\dfrac{1}{3} -1\dfrac{1}{4}

<u>convert into improper fraction</u>

\rightarrow \sf \dfrac{13}{3} -\dfrac{5}{4}

<u>make the denominators same. 12 is the common factor of both 3 and 4</u>

\rightarrow \sf \dfrac{13(4)}{12} -\dfrac{5(3)}{12}

<u>simplify</u>

\rightarrow \sf \dfrac{52}{12} -\dfrac{15}{12}

<u>join both fraction</u>

\rightarrow \sf \dfrac{52-15}{12}

<u>simplify</u>

PLEASEEE HELP FAST
Arada [10]

Answer:

1. During part 2. The y-axis (line going up) represents his distance. At part 1, his distance stays the same because he is sitting in the park. At part 2 we see the line go down, which means his distance from home is decreasing.

2.At part 3. His distance stays the same, which represents him waiting in line. We know this because the line stays at the same distance and the time increases(this is the x-axis)

3. There would be another part of the graph. If he had stopped again, there would have been another straight line with the distance the same and the time increasing.

A college cafeteria pays student cashiers $10.20 per hour. Cashiers earn an additional $1.30 per hour for each hour worked over
nadya68 [22]
First week: 40 hours

Total Earning = 40 x $10.20 + (40 - 35) x $1.30 = $414.50

Second Week: 38 hours
Total Earning = 40 x $10.20 + (40 - 38) x $1.30 = $410.60

Total for the two weeks = $414.50 +  $410.60 = $825.10

Answer: $825.10
