What is the sum of 70 plus 30 plus 1250 plus 50 plus 100?
The sum of 70 + 30 + 1250 + 50 + 100 = 1500
How can 70 percent and 30 percent equal 50 percent?
If you have 70% of something and 30% of another identical "something" that is equivalent to 50% of the two "somethings".
What is 70 plus 65 plus 50 plus 73 plus 57 plus 47 equal?
362. Next time, just use a calculator.
What is 70 plus 80 plus 70 plus 30 plus 80 plus 80 plus 80?
70 + 80 + 70 + 30+ 80 + 80+ 80 = 490
Why does the area of 70 times 30 equal 2100 but the area of 50 times 50 equal 2500 square feet?
If you have two pairs of numbers whose sum is the same, their product increases as the two numbers get nearer to half the sum. The product is a maximum at that value. 70 * 30 = (50+20)*(50-20) The right hand side is the factorisation of the difference of two squares, and can be shown to be equal to 502 - 202 Since 202 must be positive (it is a square), 70*30 must be less. For all values of x, (50+x)*(50-x) is less than or equal to 50*50=2500 with equality attained only when x = 0.
