### Suatu lahan parkir mempunyai luas 468 m2. Untuk sebuah mobil dan sebuah bus, berturut-turut membutuhkan lahan 6 m2 dan 26 m2. Lahan parkir itutidak dapat memuat lebih dari 28 kendaraan. Jika biaya parkir untuk sebuah mobil Rp3.000,00 dan sebuah bus Rp5.000,00 maka pendapatan maksimum yang diterima oleh tukang parkiradalah....

• A.

Rp54.000,00

• B.

Rp84.000,00

• C.

Rp90.000,00

• D.

Rp114.000,00

• E.

Rp140.000,00

D. Rp114.000,00
Explanation
The maximum number of vehicles that can be accommodated in the parking area is determined by dividing the total area of the parking lot (468 m2) by the sum of the area required for a car and a bus (6 m2 + 26 m2 = 32 m2). This gives us a maximum capacity of 468 m2 / 32 m2 = 14.625 vehicles. Since the parking lot cannot accommodate more than 28 vehicles, the maximum number of vehicles that can be parked is 14. Therefore, the maximum revenue that the parking attendant can earn is 14 vehicles * (Rp3,000 for a car + Rp5,000 for a bus) = Rp114,000.

### Siswa yang sedang berlibur ke suatu pantai melihat sebuah menara. Jarak menara dengan dirinya 120 m. Ujung menara terlihat dengan sudut elevasi 600 dari titik pengamatan. Tinggi menara tersebut adalah ….

• A.

Option 1

• B.

Option 2

• C.

120 m

• D.

Option 5

• E.

Option 4

D. Option 5
Explanation
The correct answer is Option 5. Since the student is observing the top of the tower with an elevation angle of 60 degrees, we can use trigonometry to find the height of the tower. The height of the tower can be calculated using the formula: height = distance * tan(angle). Plugging in the values, we get height = 120 * tan(60) = 120 * √3 = 207.85 m. Therefore, the height of the tower is approximately 207.85 m.

### Suatu kotak kecil berisikan 4 mur baut berbahan A dan 8 mur baut berbahan B dengan kedua jenis memiliki ukuran yang sama. Jika diambil secara acak tiga mur baut, peluang terambil sedikitnya dua mur baut berbahan A adalah ….

• A.

Option 1

Option 2

• C.

Option 3

• D.

Option 4

• E.

Option 5

B. Option 2
Explanation
The probability of choosing two bolts of material A out of three randomly selected bolts can be calculated by considering the different combinations of bolts that can be chosen. Since there are four bolts of material A and eight bolts of material B, the total number of possible combinations of three bolts is 12C3 = 220. The number of combinations that include two bolts of material A can be calculated as 4C2 * 8C1 = 6 * 8 = 48. Therefore, the probability of choosing at least two bolts of material A is 48/220 = 12/55, which corresponds to option 2.

### Pada percobaan lempar undi 3 keping uang logam sebanyak 240 kali. Frekuensi harapan munculnya 2 angka adalah ….

• A.

60 kali

• B.

80 kali

• C.

90 kali

• D.

120 kali

• E.

180 kali

D. 120 kali
Explanation
The expected frequency of getting 2 numbers when tossing 3 coins 240 times is 120 times. This can be determined using the concept of probability. When tossing 3 coins, there are 8 possible outcomes: 3 heads, 3 tails, and 6 combinations of 2 heads and 1 tail. The probability of getting 2 numbers is therefore 6/8 or 3/4. Multiplying this probability by the total number of tosses (240) gives us the expected frequency of 120 times.

### Seorang pedagang membeli 10 kaleng cat jenis A dan 15 kaleng jenis B dengan harga Rp 1.440.000,00. Pada hari yang lain, ia membeli 12 kaleng cat jenis A dan 20 kaleng jenis B dengan harga Rp 2.310.000,00 dan mendapat potongan 20 %. Jumlah harga satu kaleng cat A dan satu kaleng cat B adalah ....

• A.

Rp100.000,00

• B.

Rp 114.000,00

• C.

Rp 120.000,00

• D.

Rp 125.000,00

• E.

Rp 126.000,00

B. Rp 114.000,00
Explanation
The correct answer is Rp 114.000,00. To find the price of one can of cat A and one can of cat B, we can set up two equations using the given information. Let x be the price of one can of cat A and y be the price of one can of cat B. From the first purchase, we have 10x + 15y = 1.440.000. From the second purchase with a 20% discount, we have 12x + 20y - 0.2(12x + 20y) = 2.310.000. Solving these equations simultaneously, we find x = 114.000 and y = 114.000. Therefore, the price of one can of cat A and one can of cat B is Rp 114.000,00.

### Suatu perusahaan mempunyai tanah seluas 8.400 m2 akan dibangun cluster rumah dengan dua tipe, yaitu tipe anyelir dan tipe Amanda. Untuk rumah tipe Anyelir diperlukan tanah seluas 180 m2 dan untuk tipe Amanda diperlukan tanah seluas 264m2. Perusahaan tersebut merencanakan banyak rumah yang akan dibangun tidak lebih dari 36 unit. Jika banyak rumah tipe anyelir dinyatakan dengan x dan rumah tipe Amanda dinyatakan dengan y, model matematika dari permasalahan tersebut adalah ….

• A.

X + y ≤ 36; 15x+22y ≤ 700; x ≥ 0 dan y ≥ 0

• B.

X + y ≤ 36; 15x+22y ≥ 700; x ≥ 0 dan y ≥ 0

• C.

X + y ≤ 36; 15x+11y ≤ 700; x ≥ 0 dan y ≥ 0

• D.

X + y ≤ 84; 22x+15y ≤ 700; x ≥ 0 dan y ≥ 0

• E.

X + y ≥ 84; 22x+15y ≤ 700; x ≥ 0 dan y ≥ 0

A. X + y ≤ 36; 15x+22y ≤ 700; x ≥ 0 dan y ≥ 0
Explanation
The correct answer is x + y ≤ 36; 15x+22y ≤ 700; x ≥ 0 and y ≥ 0. This answer represents the constraints for the problem correctly. The first inequality x + y ≤ 36 ensures that the total number of houses built (x + y) does not exceed 36 units. The second inequality 15x+22y ≤ 700 represents the total land area required for both types of houses, which should not exceed 700 m2. The last two inequalities x ≥ 0 and y ≥ 0 ensure that the number of houses for each type cannot be negative.

The maximum profit that the company can obtain for producing x units of goods is 2,400 million rupiahs. This is based on the given information that the cost to produce one unit of goods is (100 - x) million rupiahs, and the company wants to maximize its profit. Therefore, the company will maximize its profit when the cost is minimized, which occurs when x is at its maximum value. By substituting the maximum value of x into the cost equation, we can find the maximum profit of 2,400 million rupiahs.

### Sebuah peluru ditembakkan vertikal ke atas. Tinggi peluru (h) dalam meter dengan waktu (t) dalam sekon dinyatakan dengan h(x) = 21t  ̶  6t2. Waktu untuk mencapai tinggi maksimum adalah ….

• A.

1 sekon

• B.

1,25 sekon

• C.

1,5 sekon

• D.

1,75 sekon

• E.

2 sekon

D. 1,75 sekon
Explanation
The equation h(x) = 21t - 6t^2 represents the height (h) of a bullet shot vertically upwards in meters as a function of time (t) in seconds. To find the time it takes for the bullet to reach its maximum height, we need to find the vertex of the parabolic function. The vertex can be found using the formula t = -b/2a, where a = -6 and b = 21. Plugging in these values, we get t = -21/(2*(-6)) = 1.75 seconds. Therefore, the bullet takes 1.75 seconds to reach its maximum height.

Option 3

• D.

Option 4

• E.

Option 5

C. Option 3
Explanation
The distance between point A and point G in a cube is equal to the length of the diagonal of one of the faces of the cube. Since the length of AB is given as 5 cm, the length of the diagonal of the face is also 5 cm. Therefore, the distance between point A and point G is also 5 cm.

• B.

Option 2

• C.

Option 3

• D.

Option 4

• E.

Option 5

E. Option 5
Explanation
The question asks for the distance between point C and line PG. Since point P is the midpoint of BD, line PG is the perpendicular bisector of BD. Therefore, point C will be equidistant from both point P and line PG. Therefore, the distance between point C and line PG is equal to the distance between point C and point P, which is half of the length of BD. Since the length of BD is 8 cm, the distance between point C and line PG is 4 cm.
