**Physics**

KE=.5m(v)^2 so we have 1250 times 121 then divide by 2. the formula reads kinetic energy equals mass times velocity squared then divided by 2

**math plz help**

its one over the number or variable you are given as seen in the example given by dbob222. you are just switching the position of hte numerator and denominator

**Math 62**

when you solve for the equation, you can easily graph. for example lets say the equation you got is y=3x+3 (i just made it up. not the answer to your problem) What this equation says is if you know X, you can multiply by 3 and then add 3 and you will get the Y value. So just p...

**Biology**

I can answer the first part. Genetic engineering can be used to enhance produce traits. For example, sweeter fruit and larger size.

**MATH**

when you want to solve for a variable you want your asnwer to look like x=? So you need to separate x from everything else. So the first thing to do would be to subtract 4 from 7. So you end up with 3x=3. Now we need X not 3X. So divide both sides by 3. Then we get x = 1

**science**

you would need the heat of fusion i beieve for melting and boiling. then its a normal stoich. problem

**Math**

you take the number and put it over 5000. for ex, 1835/5000 times 100 = the percent of labor

**science**

Draw a picture ======> | | | the distance that connects the two ends of the line is the total distance. Use the pythageroen theorem

**maths **

litres and meters are different measurements. 1cc = 1 mL. I would suggest you convert the initial dimensions to centimeters. So that when you get the volume, it would be in cubic centimeters. And 1 cubic centimeter is 1 milliliter. 1000 milliliters in one liter

**Economics**

Price should rise with demand if the supply is limited.

**Computers**

RAM is a place where memory is held and can be constantly accessed despite of location. I am not too sure of what that particular question is asking as the term electronic holding area is new to me.

**Computers**

RAM is random access memory.

**physics**

you would draw the picture and get the initial y velocity. then, use any one of the possible equations to get the max height it goes. (at max height, velocity in the y direction is 0) when you get that height, subtract it from the max to get the initial platform height

**algerbra **

q-16. Less than means subtract. so 16 less than q means subtract 16 from q. For example, in everyday lingo we say something is 3 less. but we have just ommited the relation. "it is 3 less than 10"

**grd1 math**

10 + 2 ________ 12 you add each place value. you have to line up the numbers. You can think of 2 as 02. We just dont write 0 in front of numbers because it is pointless.

**Macroeconomics**

I am not entirely sure of this but I will explain from what I know. The reserve ratio is the amount of money banks have to have on hand. For example, if a bank had 100 dollars, it is required to keep 25% of it if the ratio os .25. The other 75 can be lent. So 75 is in the mone...

Density = mass/volume 2/6 = 1/3g/cm^3 the g/cm^3 are the units.

**ALGEBRA**

take square root of both sides after dividing by 3.

**Algebra**

11 squared is 121 and 12 squared is 144. 139 lies in between

**Microeconomics**

I took macro but revenue should increase with the amount sold.

**algebra**

slope is change in y divided by change in x 0-5=-5=y -2-0=-2=x 5/2 is slope so we have y=5/2x + b plug in the point 0,5 now we have 5=5/2(0) + b b=5. the same for the next problem.

**computers**

Easter eggs are just things the coders put into the program. It can be a joke or something symbolic. It doesnt really affect the program
