What is the 40 times table?
40x1=40 40x2=80 40x3=120 40x4=160 40x5=200 40x6=240 40x7=280 40x8=320 40x9=360 40x10=400
What is what is break apart math for 4th grade?
You take all the answers and add it all together. Break apart is a multiplication strategy. To multiply 45 and 6, you first break apart the 45 into 40 and 5, now multiply both with multiplier 6. Then add both of them. This is 40x6 + 5x6= 240 + 30 = 270

What is multiply 3 with 1?
You do it like this. 6 times 7 times 2. 6 times 7 is 42. Then 42 times 2 is 84. You multiply the first number times the second number and then the product times the third number Example: 5x8x6 5x8=40 40x6=240 The answer to that problem is 240

How do you calculte bebding moment for simply supported beam?
First, pick the point along the beam at which you need the bending moment. Then make sure that all the forces on the beam to the right of the chosen point are correctly known. Then calculate the moment about the chosen point each of those forces contributes . Add these up and that is the answer. For example, consider a 12 metre beam supported at the 4 metre point and the 12 metre point. There is a 10 Kg load at the 0 metre end and a 40 Kg load at the 10 metre point. Find the bending moment at the 8 metre point. First we need the loads at the two supports, L1 and L2. L1 + L2 = 10 + 40 = 50 Kg Total forces up equals total forces down. And we shall work out all clockwise and anticlockwise moments about the support at the 4 metre point. (The total moments about any point is zero.) Clockwise: 40x6 Anticlockwise: 10x4 + L2x8 Putting clockwise = anticlockwise we get 240 = 40 + 8xL2 hence L2 = 200/8 And from L1 + L2 = 50 we now get L1 + 25 = 50 hence L1 = 25 So to answer the question - Find the bending moment at the 8 metre point - we just sit at the 8 metre point and look right. We see the 40 Kg load 2 meters away pushing down and the 25 Kg up-force at the end, 4 meters away. That makes a moment of 40x2 mKg clockwise and 25x4 anticlockwise. That results in a total of 25x4 - 40x2 anticlockwise. The answer is 20 mKg anticlockwise ( upward) about the 8 meter point.
How many loaves of bread to feed 40 people?
Depends on a couple factors: - How the meat is being served: Is it a big stew? Is it steak? I'm assuming its all sit-down meals. - Who are the people, How much will they eat: Are they a football team or a nursing conference? For most meats, figure big men would eat between 10-16 ounces, small women would eat 6-10 ounces. On average, 10oz pp, coming out to 400oz for 40 people or 25 pounds. This is figuring liberally. More advice: Cook less, season more.
How do you prepare 6N sodium hydroxide?
There are several methods for producing sodium hydroxide, or NaOH. The most common way of making NaOH at least as long ago as several hundred years if not more than 1000 was by mixing sodium carbonate, lime, and water. Lime is calcium hydroxide, which is made by heating a mixture of water and crushed limestone. The reaction of sodium carbonate and lime in water is: Na2(CO3) + Ca(OH)2 -----> CaCO3 + 2 NaOH The calcium carbonate formed is barely soluble in water, therefore the solution of NaOH is poured, filtered, or pumped away from the calcium carbonate precipitate and the water is allowed to evaporate away. A solution of NaOH can be easily made by allowing sodium metal to react with water. However, DO NOT PERFORM THIS REACTION WITHOUT A PROFESSOR'S GUIDANCE! The reaction produces hydrogen gas and a lot of heat; enough to ignite the hydrogen and air mixture, which will cause an explosion. Today, most NaOH is made using DC electricity and seawater. The anode is immersed in, or fed filtered seawater, and it is surrounded by a semipermeable membrane through which chlorine gas cannot pass and enter the solution. At the surface of the anode, chloride ions are oxidized to chlorine gas which is captured. Of course the cathode must be in electrical contact with the anode and the ionic balance must be maintained or nothing will happen. It's impossible to remove chloride anions without either replacing them with another anion or removing an equal number of cations. When making sodium hydroxide, water is reduced at the cathode to hydrogen gas and hydroxide anions, which replace the lost chloride ions and keep the reaction going. Thus, what is left in the seawater are the sodium and hydroxide ions, plus small concentrations of other ions. Solid NaOH is made by removing the water, probably by vacuum distillation. More pure NaOH can be made by recrystallizing the initial NaOH, or ion-exchange resins may be used to remove ions other than Na+ and OH-. There may be other methods for purifying the initial NaOH. The reason the chlorine gas must be removed is because a solution of chlorine gas in sodium hydroxide forms chlorine bleach, like Clorox®.
