EXERCISE 7 1. A leather armchair has a cash price of R5 000. If bought on h deposit must be put down and the balance paid over 24 mon rate of \( 18 \% \) p.a. SI. a) What is the total amount paid for the armchair? b) How much of this was interest? c) Calculate the monthly instalment. 2. Sizwe wants to buy an electric stove. He finds one for R12 or him the option of two hire purchase deals. Option \( 1: \) A deposit of \( 20 \% \) of the cash price, with the balan over 36 months at \( 20 \% \) p.a. SI. Option 2 : A deposit of R2 000 , with the balance to be paid at \( 22 \% \) p.a. SI. a) Calculate the total amount paid for the stove and the m i) Option 1 ii) Option 2 . b) If you were Sizwe, which option would you choose and

\( 9 = 12,8,15,5,18,2 \)

Guru PJOK seharusnya mampu merancang daftar latihan kebugaran jantung dan paru yang sesuai untuk tiap-tiap peserta didik dalam 1 kelas. Latihan yang dipilih, tentunya harus dapat memacu kerja jantung minimal bisa masuk ke nadi di zona latihan. Target denyut nadi berikut yang paling tepat adalah .... \( 60-90 \) denyut/menit 220 -usia denyut/menit \( 70 \% \times 220 \) denyut/menit \( 85 \% \times 220 \) denyut/menit \( 70-85 \% \) dari denvut nadi maksimal

This! Write an equation of the line given the slope and \( y \)-intercept. Express the equation in the \( \underline{m x}+b \), if possible. \( n=-2, b=5 \) \( n=-5, b=9 \) \( n=-3, b=3 / 2 \) Find the equation of the line having the specified slope and containing the indicated point equation in slope-intercept form. \( n=2 ;(5,-2) \) \( n=2 / 3 ;(-1,2) \) \( n=-4 ;(-2,-3) \)
