(b) A two-storey car park has a total of 1020 parking spaces. At \( 06: 30 \) hours one morning, \( \frac{1}{30} \) of the 1020 spaces are filled. During the next hour, no cars left the car park but another \( \frac{4}{15} \) of the 1020 spaces are filled. Determine the number of parking spaces that are NOT filled at \( 07: 30 \) hours. (c) \( \begin{array}{l}\text { Of the } 1020 \\ \text { the top level? }\end{array} \)

The capacity of three containers is 30 liters, 45 ers and 60 liters. Determine the capacity of the eatest container which can be used to fill each the container in exact number of times?

What percentage is 36 of 82 ?

With your teacher: The first term of a arithmetic sequence is 14 . The \( 7^{\text {th }} \) term is 50 . Find: (a) The common difference ' \( d \) '. (b) The rule for the sequence. The \( 6^{\text {th }} \) term of an arithmetic sequence is 123 . The \( 11^{\text {th }} \) term is 98 . Find; (a) The common difference ' \( d \) ' and first term ' \( a \) '. The rule for the sequence. (b) (c) \( 16^{\text {th }} \) term.

Suites arithmétiques Les questions sont indépendantes. 1. On définit pour tout \( n \) la suite \( \left(U_{n}\right) \) par : \[ U_{n}=3 n-2 \] Montrer que \( \left(U_{n}\right) \) est une suite arithmétique. 2. Soit \( \left(U_{n}\right) \) une suite arithmétique de premier terme \( U_{0}=5 \) et de raison \( \frac{1}{3} \). Calculer le \( 9^{\text {ieme terme, puis calculer la }} \) somme : \( S=U_{0}+U_{1}+U_{2}+\ldots+U_{8} \)

If \( 3^2 \) is calculated, what is the result?
