A construction crew needs to pave a road that is 207 miles long. The crew paves 7 miles of the road each day. The length, \( L \) (in miles), that is left to be paved after \( d \) days is given by the following function. \( L(d)=207-7 d \) Answer the following questions. (a) How many miles of the road does the crew have left to pave after 12 days? miles (b) If 158 miles of the road is left to be paved, how many days has the crew been paving the road? days

1. The diagram on the centres \( C \) and \( D \). Give 0 cm and 3 cm respect rangent to both circles, (a) the length of \( Q R \), to three significant (b) the area of quadril answer correct to \( f \)

The forms who have successfully collected more than the minimum amount of money in the carnival set by the school will be awarded with prizes. Given the probability of form 4 and form 5 being selected are \( \frac{1}{10} \) and \( \frac{3}{4} \) respectively. Calculate the probability (i) tingkatan 4 atau tingkatan 5 dipilih, form 4 and form 5 are selected, (ii) tingkatan 5 sahaja dipilih. only form 5 is selected.

1 Consider these relations. Classify them as one-to-one, many-to-one, many-to-many or one-to-many. a \( \{(1,2),(2,3),(1,4)\} \) b \( \{(1,2),(2,3),(3,6)\} \) c \( \{(1,1),(2,1),(3,1)\} \) d \( (1), 1) \)

\begin{tabular}{l} FLUENCY \\ \hline The equation of the line that passes through \( (1,1) \) and \( (3,-4) \) is: \\ A \( 2 y=3 x+1 \) \\ B \( \quad 2 y=-5 x+7 \) \\ C \( \quad 5 y=2 x+7 \) \\ D \( \quad 2 y=-5 x+3 \) \\ E \( \quad 3 x=2 y+1 \)\end{tabular}

The POTW Input/Output Machine takes a number as input and adds 10 to the numb The machine then takes this sum and mult plies it by 2 . Finally, the machine takes this product, subtracts 30 from the number, an outputs this new number. Anala and Mei each input a positive intege into the machine. If the sum of their two ou puts is 130 , how many possibilities are the for the positive integer that Anala input int the machine?
