Haya master, hapa kuna masuluhisho ya maswali uliyotuma: 22. (a) Workout: (12.8 × 0.75)/(0.32) Step 1: Zidisha namba kwenye kiasi (numerator). 12.8 × 0.75 = 9.6 Step 2: Gawanya matokeo kwa kigawo (denominator). (9.6)/(0.32) Ili kurahisisha, zidisha kiasi na kigawo kwa 100 ili kuondoa desimali. (9.6 × 100)/(0.32 × 100) = (960)/(32) Step 3: Fanya mgawanyiko. (960)/(32) = 30 Jibu: 30 22. (b) Simplify: 5(1)/(4) - 5(1)/(2) ÷ 4(2)/(5) Step 1: Badilisha namba mchanganyiko kuwa sehemu zisizofaa. 5(1)/(4) = ((5 × 4) + 1)/(4) = (21)/(4) 5(1)/(2) = ((5 × 2) + 1)/(2) = (11)/(2) 4(2)/(5) = ((4 × 5) + 2)/(5) = (22)/(5) Usemi unakuwa: (21)/(4) - (11)/(2) ÷ (22)/(5) Step 2: Fanya mgawanyiko kwanza (kulingana na utaratibu wa shughuli). (11)/(2) ÷ (22)/(5) = (11)/(2) × (5)/(22) (11 × 5)/(2 × 22) = (55)/(44) Rahisisha sehemu kwa kugawanya kiasi na kigawo kwa 11. (55 ÷ 11)/(44 ÷ 11) = (5)/(4) Step 3: Fanya kutoa. (21)/(4) - (5)/(4) = (21 - 5)/(4) (16)/(4) = 4 Jibu: 4 23. Kimeny's plot is shaped as shown below with corners A and D. Swali hili halijakamilika. Picha inaonyesha umbo la trapezi (trapezium) na vipimo vya pande mbili sambamba (80m na 140m). Hata hivyo, urefu wa AD (ambao ni urefu wa trapezi) haujatolewa, na hakuna swali lililoulizwa (kama vile kutafuta eneo au mzingo). Tafadhali toa swali kamili na urefu wa AD ili niweze kukusaidia. 3 done, 2 left today. You're making progress.
