What is the surface area of rectangular prism that is 5cm 2cm 10cm?
Area = 2*(L*B + B*H + H*L) = 2*(10 + 20 + 50) = 2*80 = 160 cm3

A/b = 50/88 = 0.5681818181
The perimeter of a rectangle is 100cm what could be its area?
This is solved by simultaneous equations. Perimeter = 2a + 2b = 100 where a and b are lengths of sides Area = a x b Rearranging the perimeter equation: 2a = 100 - 2b, a = 50 - b Putting this equation into the area equation: Area = (50 - b) x b = 50b - b x b Find the minimum/maximum by differentiating and setting to 0. Area' = 50 - 2b = 0, 2b = 50, b = 25 Area = 625cm sqare. when the length tends to 50, the area tends to 0. So the area can be anything from 0 to 625 cm

What percent of 50 is b?
b/50 = 100*b/50 % = 2b per cent.
Find b 140 80 and 100?
50
If b equals a plus 40 and 2a plus 2b equals 160. solve for a and b?
2a + 2b = 160 But b = a + 40 so 2a + 2(a + 40) = 160 ie 2a + 2a + 80 = 160 or 4a = 80 ie a = 20 Then b = a + 40 gives b = 20 + 40 = 60 Solution: a = 20, b = 60

What percent of 175 is 160?
You set it up as a proportion problem... so 160/175 = B / 100 B is the percentage you are solving for Cross multiply (i.e. 100 x 160 = 16,000) And divide (i.e. 16,000 / 175 = 91.43) This is your answer! 160 is 91.43% of 175
How do you answer a direct proportion?
this is the question: A is directly proportional to B² When A=50, B=10 a) Find an equation connecting A and B. the formula to start answering this question is A (direct proportion sign) B² A=K*B² then you have to fill in the numbers for A and B² so you get this: 50=K*10² 50=K*100 so then you have to find out K so you have to do 50/100 which is 0.5 so K=0.5. THen you have to write the equation in full to get the full marks so it's just: A=0.5*B². ---------------------------------------- then you will have to put your formula in action so say that the question was: b) find the value of B when A is 72 you would have to substitute the numbers is so that its : 72(A)=0.5(K)*B so then you would have to divide 72 by 0.5 to get the answer which is 144. Then you have to remember to SQUARE ROOT 144 to get B becasue you have only got B², not just B. so the final answer is ... 12! i hope this helped x
How much of each of 24 percent salt solution and 64 percent salt solution should be mix in order to produce 160ml that is a 43 percent salt solution?
Let's say the amount of 24% solution is A and that of 64% is B. We know from the clue A+B = 160ml. Out of A+B=160, we can get A=160-B We can express the solution as A.24/100 + B.64/100 = 160.43/100 to simplify multiply each term with 100 and we get 24A + 64B = 6880 to further simplify divide each term with 8 and we get 3A + 8B = 860 From the clue we know A = 160-B 3(160-B) + 8B = 860 480 - 3B + 8B = 860 5B = 860-480 5B = 380 B = 76ml A = 160-B A = 160- 76 A = 84 ml therefore the answer is * 84ml of 24% solution + 76 ml of 64% solution = 160ml of 43% solution

How do you find the percentage of a number?
I'll demonstrate this with some examples: To find 50% of something, you divide 50 by 100 to get 0.5 and then multiply it by the number you wish to find the percentage of. So 50% of 413 is 0.5 times 413 = 206.5 To find 22% of 40, you divide 22 by 100, to get 0.22 and multiply this by 40 to get 8.8 So in general to find a% of b. divide a by 100 and times it by b to get the answer. or, another way to find 22% of 40 (or any % of any other numbers)is as follows: Let the % to be found (in this case, 22) be A. The number (in this case, 40) be B. then (B/100) x A= the number you are searching for (the numeric value of the percentage)
