Math question: If Sally wants to distribute 76 cookies equally among her 4 friends, how many cookies will each friend receive?

To find out how many cookies each friend will receive, we divide the total number of cookies, which is 76, by the number of friends, which is 4. 76 ÷ 4 = 19. Therefore, each friend will receive 19 cookies.

Math Question: What is the sum of the first 38 even numbers after 76?

To find the sum of the first 38 even numbers after 76, we first determine the next even number after 76. We add 2 to 76, which gives us 78. Following this pattern, we continue adding 2 to each subsequent even number to obtain the sequence 78, 80, 82, 84, and so on. The sum of the first 38 even numbers can be calculated using the formula for an arithmetic series: Sn = (n/2)(a1 + a(n)), where Sn is the sum, n is the number of terms, a1 is the first term, and a(n) is the nth term. Here, n = 38, a1 = 78 (as it is the first even number closest to 76), and a(n) = 78 + (38-1) * 2 = 154. Thus, the formula becomes Sn = (38/2)(78 + 154) = 38 * 232 = 8816. Therefore, the sum of the first 38 even numbers after 76 is 8816.

Math question: If 76 is increased by 40% and then decreased by 25%, what is the final value?

To find the final value, first increase 76 by 40%: 76 + (40/100) * 76 = 76 + 0.4 * 76 = 76 + 30.4 = 106.4 Now, decrease 106.4 by 25%: 106.4 - (25/100) * 106.4 = 106.4 - 0.25 * 106.4 = 106.4 - 26.6 = 79.8 Therefore, the final value obtained after increasing 76 by 40% and then decreasing by 25% is 79.8.
