Education 503 plan

First of all, these aren't my homework rather this is my cousins', and second, Mathematics isn't my cup of tea. Please leave at least a bit of explanation on you solved the questions so I/She can understand this. Thanks anyway. 7. What digits that make 375, 19n divisible by 6? 9. The least common multiple (LCM) of 42, 144, and 240 as a product of prime factors is? 16. The three sides of a triangle are 6 1/2 cm, 5 1/5 cm and 4 5/6 cm. What is the perimeter? 20. Two numbers are in the ratio 3:4. If one number is 16 more than the other, what is the bigger number? 25.Carlo is 2/3 as old as Ador. If the difference of their ages is 8 years. How old is Ador? 26. Two-thirds of the area of the square is 96 cm2 (square-centimeter). How long is one side of the square? 27. What percent of 64 is equal to 25% of 144? 28. In an isosceles triangle, the base is 42 cm and one leg is 28 cm. Find its perimeter. 29. The scale on the plan of the house of Mr. Caringal is 2cm:1cm. Find the dimension of the living room scaled 10 cm by 8 cm. 30. If we increase the diameter of a circle by 4 cm, by how much do we change the circumference of the circle? 31. If we count by 4's starting with 5, we get sequence 5, 9, 13, 17, 21,.... What is the 150th number in the sequence? 32. Today is Sunday. What day of the week is 150 days from today? 33. Working together 8 men can do a job in 15 days. How long will it take 10 men to finish the same job? 34. The ratio of the width to the length of a rectangular lawn is 4:5. If the area is 180 (squared......don't know how to put a small put beside it), find the length of the lawn. 35. In (there's suppose to be a small triangle here) ABC, /_ A=85 deg. and /_ B = 29 deg. What is /_ C? 36.If 204 = 8, 503 = 13, 305=11 and 907 = 25, what is 705? 37. How many 1 dm square tiles are needed to cover the floor of bathroom 2.5 m long and 1.8 m wide? 39. What is the total surface area of a cube of edge 10cm? 43. If each side of a square is enlarged 6 times, how many times as large is the new area? 44. What percent of 685 is 411? Please help, my cousin (10 yrs.old) has only me to turn to, and me,... well.... there's the internet I guess.... thanks. Another thing is, whenever she submits these kind of tests to her teacher and returns to her with her score, the teacher doesn't explain the correct answers to those that she got wrong. She has the asked the teacher for an answer sheet and yet, she has only received only nods and promises. (that's the kind of "free education" here)So please help. Someone suggested I post this on "Math" category... I hope I'll receive more help this way. Thanks

7. 19n/6 = 375 19n = 375*6 = 2250 n = 2250/19 = 118.42 9. the LCM is 2, since they all can be devided by 2 & 2 is the 1st prime number 20. a:b = 3:4 --> a/b = 3/4 --> 4a = 3b a + 16 = b --> a = b - 16 3b = 4a --> 3b = 4(b-16) --> 3b = 4b - 64 --> 64 = 4b - 3b --> b = 64 25. carlo = 2/3 ador. difference = 8 = 1/3 ador ador = 3*8 = 24 26. 2/3 part = 96 --> 1 part = 96 * 3/2 = 144 side length = sqrt 144 = 12 27. 25% of 144 = 25/100 * 144 = 1/4 * 144 = 144/4 = 36 36/64 = 9/16 = 0.5625 = 56.25% 30. circumference = 2*phi*r 2*phi*(r+4) = 2*phi*r + 2*phi*4 = 2*phi*r + 8*phi the difference would be 8phi 31. the formula would be 4n + 1 4*150 + 1 = 600 + 1 = 601 32. 150/7 = 147, the remainder is 3 --> thus is will be 3 days from sunday which is wednesday. 33. 15/8 = a/10 --> 150/8 = a --> a = 18.75 34. 4:5 --> 4n * 5n = 180 --> 20n^2 = 180 --> n^2 = 9 --> n = 3 width = 4 * 3 = 12 length = 5 * 3 = 15 35. C = 180 - A - B C = 180 - 85 - 29 = 66 37. 2.5m = 25dm, 1.8m=18dm area = 25*18 = 450dm^2 amount of tiles needed = 450/1 = 450 pieces 39. amount of cube surface is 6. total surface = 6 * 10 * 10 = 600cm^2 43. (6*side)^2 = 6^2 * side^2 = 36 * side^2 thus the new one is 36 times. 44. (411/685)*100% = 0.6*100% = 60% sorry, I have to skip a few of those problems due to time. hope those help you out...

She's in a competition in Math and yet somehow the questionnaires for this year got much harder compared to the ones she showed me last grade 3.
