Jawaban: A = 12,56 m²
Keliling, luas, dan volume: keliling adalah jarak di sekeliling suatu bangun (persegi panjang: 2p + 2l). Luas diukur dalam satuan persegi: persegi panjang p × l, segitiga ½ × alas × tinggi, lingkaran π·r². Keliling lingkaran adalah π·d = 2π·r. Volume dalam satuan kubik: balok p × l × t, tabung π·r²·t. Gunakan nilai π yang diberikan soal.
Jawaban: x = 155 $
Persentase terbalik: jika suatu nilai sudah dinaikkan atau diturunkan sebesar persen tertentu, nilai barunya adalah persen dari nilai semula, bukan sebaliknya. Setelah diskon 20%, harga menjadi 80% dari harga semula, jadi harga semula = harga baru ÷ 0,80. Jangan pernah menambahkan 20% kembali ke harga baru.

Antibiotik bekerja pada struktur bakteri seperti dinding peptidoglikan dan ribosom 70S. Virus tidak memiliki satu pun dari struktur ini, sehingga tidak ada yang menjadi sasaran antibiotik.
Jawaban: D · It helps keep body temperature stable
Water must absorb or lose a lot of energy to change temperature. Because the body is mostly water, its temperature changes slowly, which helps maintain a stable core temperature.
Jawaban: A · Zn + CuSO₄ → ZnSO₄ + Cu
Zinc goes from 0 to +2 and copper from +2 to 0, so electrons are transferred. In the other reactions every element keeps its oxidation number, so they are not redox.
Jawaban: D · so
“So” shows a result. “But” shows contrast, and “or” and “nor” show alternatives.
Jawaban: A · wear
