1001011 in base 10 you get 1 and multiply it by 10, and then what you get multiply by 10 and on.so. 1 10*1=10 10*10=100 100*10=1000 and on now you have 75 which is 7*10+5*1 so you get 7 times 10 and 5 times 1 in base 2 it would be 1 1*2=2 2*2=4 4*2=8 8*2=16 16*2=32 32*2=64 now you need 75 which is 1*64+0*32+0*16+1*8+0*4+1*2+1*1 so it gives together 1001011

one thousand dollars Since there are 100 cents in a dollar, 100 times 5 times 2 or 100*5*2= 1,000 dollars.

What are you carrying on about? It s half past midnight EST. There are no algebra classes that meet at 1:30 AM. Neither are there emergencies in a math class. You have simply put off doing your homework. If you learn the material as the class proceeds you will always know everything you need to pass a test at any time. Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it s 7/8" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8" is going to be 7/16". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom. Other rulers are divided into 10 and 100 parts. But an inch is still and inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn t it? Practice this a bit and people will think you went to wizard school. Now to attack your problem. You are given two points on a graph: (6, 850) and (8, 710), where x is time and y is cubic yards. To draw the graph you first find the slope. That is rise over run. Run is the change in value of x going from left to right. Run is always positive because we always go left to right. Rise is the change in y in that interval. A negative rise means it drops. In this case run is 8 - 6 = 2 and rise is 710 - 850 = -140 so slope is -140/2 = -70. Now we can write an equation. The equation of a line is y = mx. That line runs through the origin. If we want it to run through a point (a, b) we simply subtract the coordinates: (y - b) = m(x - a). So our equation is: (y - 850) = -70(x - 6) You can use either point and get the same answer. You can now rewrite this in any desired form. Point-slope form would be: y = -70x + 420 + 850 y = -70x + 1270 Part b is up to you.
