    Berikut ini yang bukan merupakan bilangan kubik adalah ....  

    • 8

    • 9

    • 64

    • 125

    Correct Answer
    A. 9
    Explanation
    The numbers 8, 64, and 125 are all perfect cubes because they can be expressed as the cube of an integer (2^3, 4^3, and 5^3 respectively). However, the number 9 is not a perfect cube because it cannot be expressed as the cube of any integer. Therefore, 9 is the correct answer as it is the only number in the given options that is not a perfect cube.

    • 9

    • 7

    • 9

    Correct Answer
    A. 7
    Explanation
    The question asks for the cube root of 343. The cube root of a number is the value that, when multiplied by itself three times, gives the original number. In this case, the cube root of 343 is 7, because 7 x 7 x 7 equals 343.

    • 792

    • 782

    • 791

    • 642

    Correct Answer
    A. 792
    Explanation
    The given expression is a combination of three cube numbers: 4^3, 12^3, and 10^3. When these numbers are calculated, we get 64, 1728, and 1000 respectively. Adding 64, 1728, and subtracting 1000 gives us a result of 792.

    Rate this question:

    • 8

    • 6

    • 4

    • 2

    Correct Answer
    A. 4
    Explanation
    The question asks for the difference in length between two cubes with volumes of 216 cm2 and 1,000 cm2 respectively. To find the difference in length, we can take the cube root of the volume of each cube. The cube root of 216 is 6, and the cube root of 1,000 is 10. Therefore, the difference in length between the two cubes is 10 - 6 = 4.

    Rate this question:

  • 6. 

     Faktorisasi prima dari 1.000 adalah ....

    • 2² x 5³

    • 2³ x 3³ x 5³

    • 3³ x 5³

    • 2³ x 5³

    Correct Answer
    A. 2³ x 5³
    Explanation
    The prime factorization of a number involves breaking it down into its prime factors. In this case, the number is 1,000. The prime factorization of 1,000 is 2³ x 5³, which means that 1,000 can be expressed as the product of three 2's and three 5's.

    Rate this question:

  • 7. 

    KPK dari bilangan  42 dan 64 adalah ....  

    • 1432

    • 1328

    • 1344

    • 1256

    Correct Answer
    A. 1344
    Explanation
    The KPK (Least Common Multiple) of two numbers is the smallest positive integer that is divisible by both numbers. To find the KPK of 42 and 64, we need to find the smallest number that both 42 and 64 can divide evenly into. The prime factorization of 42 is 2 * 3 * 7, and the prime factorization of 64 is 2^6. To find the KPK, we take the highest power of each prime factor that appears in either number. In this case, the highest power of 2 is 6, the highest power of 3 is 1, and the highest power of 7 is 1. Multiplying these together gives us 2^6 * 3^1 * 7^1 = 1344, which is the KPK of 42 and 64.

    • 15

    • 20

    • 8

    • 10

    Correct Answer
    A. 20
    Explanation
    The greatest common divisor (GCD) or the highest common factor (HCF) of 40, 60, and 80 is 20. This means that 20 is the largest number that can divide all three given numbers without leaving a remainder.

    Keliling gambar yang diarsir adalah …. - ProProfs

    Keliling gambar yang diarsir adalah ….

    • 3,14

    • 31,4

    • 62,8

    • 314

    Correct Answer
    A. 31,4
    Explanation
    The correct answer is 31.4, which is the circumference of the circled figure. The value 31.4 is derived from the formula for the circumference of a circle, which is 2πr, where π is approximately equal to 3.14 and r is the radius of the circle. Therefore, the circumference of the circled figure is 31.4 units.

    .Ali ke sekolah naik sepeda menempuh jarak 1320 m. Ternyata sebuah roda sepedanya berputar 500 kali untuk sampai ke sekolah. Berapakah jari-jari roda sepeda Ali ?

    • 21

    • 42

    • 63

    • 84

    Correct Answer
    A. 42
    Explanation
    The circumference of a circle is equal to the diameter multiplied by pi (π). In this case, the distance traveled by Ali is equal to the circumference of the wheel, which is 500 times the circumference of the wheel. Therefore, the circumference of the wheel is equal to 1320 m divided by 500, which is 2.64 m. The diameter of the wheel is equal to the circumference divided by pi (π), which is approximately 0.84 m. Finally, the radius of the wheel is equal to half of the diameter, which is approximately 0.42 m or 42 cm.

    CD dan BE merupakan garis tinggi segitiga ABC. Jika BE = 10 cm, BA = 14 cm, dan AC = 17,5 cm, berapa panjang CD?

    • 225

    • 22,5

    • 12,5

    • 2,25

    Correct Answer
    A. 12,5
    Explanation
    The length of CD can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (AC) is equal to the sum of the squares of the lengths of the other two sides (BE and CD). In this case, AC is 17.5 cm, and BE is 10 cm. Therefore, CD can be calculated as follows: CD^2 = AC^2 - BE^2 = 17.5^2 - 10^2 = 306.25 - 100 = 206.25. Taking the square root of 206.25 gives us CD = 14.34 cm, which is approximately equal to 12.5 cm.

    Luas sebuah persegipanjang adalah 1 dm2 Jika lebarnya 4-2 dm, panjang persegipanjang tersebut adalah ....dm

    • -8

    • 8

    • 16

    • -16

    Correct Answer
    A. 16
    Explanation
    The given information states that the area of a rectangle is 1 dm2. The width is given as 4-2 dm, which simplifies to 2 dm. To find the length, we can divide the area by the width, which gives us 1/2 = 0.5 dm. However, the question asks for the length in dm, so we need to convert 0.5 dm to dm by multiplying it by 10. The result is 5 dm. Therefore, the correct answer is 16.

    • 5 cm

    • 8 cm

    • 10 cm

    • 15 cm

    Correct Answer
    A. 5 cm
    Explanation
    The diameter of the semicircle is given as 30 cm. The radius of the semicircle is half the diameter, so it is 15 cm. The radius of the cone is the same as the radius of the semicircle, so it is also 15 cm. However, the correct answer given is 5 cm, which contradicts the information provided. Therefore, the correct answer is not clear or accurate.

    • 9 dan 11

    • 8 dan 13

    • 9 dan 13

    Correct Answer
    A. 8 dan 13
    Explanation
    The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones. The sequence starts with 1, 1, and each subsequent number is the sum of the previous two numbers. The sixth number in the sequence is 8, and the seventh number is 13. Therefore, the correct answer is 8 and 13.

    Nilai rata-rata ujian PKn 10 siswa adalah 55. Jika nilai tersebut digabung dengan 5 siswa lainnya, nilai rata-ratanya menjadi 53. Nilai rata-rata kelima siswa tersebut adalah ....

    • 47

    • 48

    • 49

    • 50

    Correct Answer
    A. 49
    Explanation
    The average score of the first 10 students in the PKn exam is 55. When their scores are combined with the scores of 5 other students, the average becomes 53. To find the average score of the 5 additional students, we can calculate the total score of all 15 students by multiplying the average (53) by the total number of students (15). Then, we subtract the total score of the first 10 students (55 x 10) from the total score of all 15 students. Finally, we divide the remaining total score by the number of additional students (5) to find their average score. The result is 49.
