Svet_ta [12734]

Kelas: VII (1 SMP)

Materi: Geometri

Kata Kunci: Garis, Sisi, Rusuk, Bidang

Pembahasan:

Suatu titik dalam geometri adalah elemen paling dasar, menunjukkan posisi yang tidak memiliki ukuran (nol panjang, nol lebar, dan nol tinggi) dan dilambangkan dengan huruf kapital.

Garis terdiri dari kumpulan titik yang memanjang tanpa batas di kedua arah.

Ruas garis adalah bagian dari garis yang terdiri dari dua titik ujung dan dinamai menurut kedua titik tersebut.

Sinar garis adalah segmen dari garis dengan hanya satu titik ujung. Dinamai berdasarkan titik ujung dan titik lain di sepanjang sinar tersebut.

Sudut terbentuk dari dua sinar yang memiliki titik ujung yang sama yang dikenal sebagai titik sudut; sinar-sinar tersebut disebut sisi-sisi sudut.

Bidang terdiri dari titik-titik tak terhingga yang membentuk permukaan datar dan meluas tanpa batas. Memiliki panjang dan lebar tak terhingga, tetapi tinggi nol. Bidang biasanya ditunjukkan dengan gambar segi empat dan dinamakan dengan huruf besar.

Rusuk adalah garis hasil pertemuan dua sisi pada bidang.

Dua bidang dapat dikatakan berpotongan jika ada garis potong antara keduanya.

Bidang sejajar apabila tidak ada garis perpotongan yang terbentuk di antara keduanya.

Dua bidang disebut berhimpitan jika semua titik terletak pada keduanya.

Mari kita analisa soal ini.

Apabila dua bidang saling bersilangan dan tidak berhimpit, maka perpotongan mereka akan membentuk garis.

Oleh karena itu, jawabannya adalah B.

Semangat!

Micah deposits C dollars in a bank. The deposited amount earns an annual interest rate of r% and becomes D dollars in t years ac
PIT_PIT [12445]

Answer:

t = \frac{100}{r} [\frac{D}{C} - 1]

Step-by-step explanation:

Let’s consider that the amount deposited, C dollars, generates r% simple interest each year.

After a span of t years, the value of the deposited C dollars reaches D dollars; our task now is to formulate a relationship using these variables to find t.

We can express this relationship through the simple interest formula:

D = C(1 + \frac{t\times r}{100})

⇒ 1 + \frac{t \times r}{100} = \frac{D}{C}

⇒ \frac{t \times r}{100} = \frac{D}{C} - 1

⇒ t = \frac{100}{r} [\frac{D}{C} - 1]

Thus, this yields the formula for t. (Answer)
