35^3 = 35 X 35 X 35 = 42875 ft^3
x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.
start with what you know: x + y = 35 x - y = 9 add them together: x + x + y - y = 35 + 9 resolve the rest of the facts: X + X = 44 X = 22 22 + y = 35 22 + y - 22 = 35 - 22 y = 13 confirm: 22 + 13 = 35 22 - 13 = 9
Lets say there are 3 isotopes of an element. A is 25% and has a mass of 24, B is 40% and has a mass of 25, and C is 35% and has a mass of 26. Multiply the mass by the percentage in decimal form and add all together. (.25 x 24) + (.40 x 25) + (.35 x 26) = weighted average. If there are more then continue (percent in decimal form x mass) and keep adding.
This is written as 35 over 5 (35 on top, 5 at the bottom, between big parentheses, without a dividing line as in a fraction), and is calculated as (35 x 34 x 33 x 32 x 31) / (1 x 2 x 3 x 4 x 5).

2/5 x 7/7 = 14/35 6/7 x 5/5 = 30/35 14/35 + 30/35 = 44/35 1 and 9 35ths
1 inch = 25.4 mm Answer = (22 x 44)/(25.4 x 25.4) = 1.5 sq inches
x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.

35 Joules is 35 newton-meters. The nergy is weight times distance = weight x .5 meters = 35 so weight is 35/.5 = 70NForce = weight =mass x acceleration ; mass =weight/gravity accel = 70/9.814 = 7.13 kg
