If the mean of 10 numbers is 58 if one number is 40. what is the mean of the other 9 numbers?
Mean of 10 numbers is 58 so sum of 10 numbers is 580. One of them is 40 so the sum of the remaining nine is 540. So mean of the remaining nine is (their sum)/9 = 540/9 = 60 don't know if I'm understanding right but isn't it roughly 3.60
How do you get 40 percent of 60?
40% of 60 = 40/100 x 60 = 4/10 x 60 = 240/10 = 24
What is the answer when you add all numbers from 40 to 60?
The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050
What two numbers have ten as a GCF?
Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
What is the LCM and GCF of 30 and 40 and 60?
Oh, dude, you're hitting me with the math questions? Okay, okay, let's see. The LCM of 30, 40, and 60 is 120 because that's the smallest number they can all be divided evenly by. The GCF of those numbers is 10 because it's the largest number that can divide all three of them without leaving a remainder. Math, man, it's like magic but with numbers.
