Multiply using duplation and mediation. 17 × 48 A. 748 B. 850 C. 816 D. 799
Weegy: There is no formula, but there is a two-step procedure. I will describe the procedure, and give an example of finding the LCM of 12, 15, [ [ and 25. (1) Find the prime factors of each of the natural numbers. 12 = 2? ? 3 15 = 3 ? 5 25 = 5? (2) Select the largest exponent on each of the prime factors. Multiply these together. 2? ? 3 ? 5? = 300 The LCM of 12, 15, and 25 is 300. ] ] User: Write the numeral as a traditional Chinese numeral. 367 User: Write the numeral as a Hindu-Arabic numeral. ss? User: Write the numeral as a Roman numeral. 503,303 User: Convert the base 10 numeral to a numeral in the base indicated. 503 to base 5 Weegy: 503 base 10 to base 5 is: 4003. [smile] User: 44+11 base 5 User: Determine whether or not the first number is divisible by the second number 775,836; 9 Weegy: Yes User: Find the sum of the terms of the arithmetic sequence. 1, 7, 13, 19, . . ., 109 n = 19 Weegy: Here's a way that is easy to both do and remember. [ When you have the sum of an equally-spaced (finite) sequence of numbers, you can think of this as being similar to finding the area of a triangle. For a triangle, Area = (Base) (Height) / 2 = (Base) (Average Height). If you think of the numbers of the sequence as being similar to the height of a triangle at n evenly spaced points, then the average of the sequence is (1 + 109) / 2 = 55, which corresponds to Height / 2 of the triangle. Likewise, the length of the sequence n = 19 can be thought of as similar to the length of the triangle's base. The equation for the sum can be written as Sum = (n) (average of sequence) = (19) (1 + 109) / 2 = (19) (55) = 1045. Therefore, the correct answer 1045 ] User:(More)
