Best ResponseYou've already chosen the best response.0Veranda is covered with tiles (30cm times 30cm): is 30 by 30 the measurement of each tile?

Best ResponseYou've already chosen the best response.0good, a centimeter is 1/100 of a meter. You said that the enire veranda is 4.2 meters squared right?

Best ResponseYou've already chosen the best response.0.03 (.03) = .0009 m^2 right?

anonymous

Best ResponseYou've already chosen the best response.0yes because you converted the cm to m

amistre64

Best ResponseYou've already chosen the best response.0thats my error... it should be .3(.3) = .09 m^2

amistre64

Best ResponseYou've already chosen the best response.0yes, we need to convert centimeters to meters to be able to determine how many m^2 one tile covers

Best ResponseYou've already chosen the best response.0I know that 7 times 6 is equal to 42; so I assume that this veranda is NOT a square. and that it is either .6 meters by 7meters, or .7meters by 6 meters. Would that be a fair assumption to you?

Best ResponseYou've already chosen the best response.04.2 by 1 meter? thats good too :) either way we need 46/23 tiles all together.

Best ResponseYou've already chosen the best response.0@amistre, is area under any curve found out by integrating the function?

amistre64

Best ResponseYou've already chosen the best response.0@think; yes. When we integrate a function, we are adding up all the little slices that it is made of. Which would equal its area.

anonymous

Best ResponseYou've already chosen the best response.0okay, so integrating=finding the area & differentiating= ?

amistre64

Best ResponseYou've already chosen the best response.0differentiating is ....finding the rate of change with respect to another variable. Differentiate with respect to (x) or (time). And thats finding the derivative.

Best ResponseYou've already chosen the best response.030cm * 30cm=900cm 900cm divide by 100m =9m*4,2m= 40 tiles

amistre64

Best ResponseYou've already chosen the best response.0cant do it like that; you have to realize that the area changes and you no longer deal with 900 cm.. each tile is .3 meters wide; (.3)(.3) = .09 m^2 you have to use this measure of area. otherwise you mess yourself up. Does that make sense?

amistre64

Best ResponseYou've already chosen the best response.0900cm^2 is not easily converted to m^2 so convert it before you find the area.

amistre64

Best ResponseYou've already chosen the best response.0Yes. .3 meters wide by .3 meters deep. .3x = 4.2 x = 14 tiles along the 4.2 meter side. .3x = 1 x = 1/.3 = 10/3 x = 3 and 1/3 tile to span 1 meter side. Do you agree with those numbers?

Best ResponseYou've already chosen the best response.024 black tiles.right ...the front of the roof is in the shape of a isosceles triangle.the side of the roof are 50cm longer at the ends of the roof hiegh is 1,7m .calculate the lenght of the sides of the of the triangle

amistre64

Best ResponseYou've already chosen the best response.0is the height from ground level to the peak or is it from the ceiling line to the peak? This information only makes sense if we have a triangle that has a height of 1.7m and has little (50cm) overhangs extending beyond the base. Is the right?

Best ResponseYou've already chosen the best response.0An isoTriangle has 60 degree corners; and the the sin(60) = 170cm/x(cm) x = 170/sin(60); then add the 50cm to get: x = 170/sin(60) + 50. Does that work for you?

amistre64

Best ResponseYou've already chosen the best response.0Kab: in order to solve this problem; you need to know how to solve right triangles. and you solve them with a formula that says the height^2 + base^2 is equal to the slanted part^2

Best ResponseYou've already chosen the best response.0(H)^2+(B)^2 (1,7)^2+(0,05)^2 2.89m+0.0025m=2.89m^2 i converted the 50cm to meter which is 0,05

amistre64

Best ResponseYou've already chosen the best response.0you are on the right track, but I have to point something out to you first. for starters the 50 sm is something we will add at the end because it is not a part of the triangle to begin with. second; we dont know the B yet in order to find the length of the side of the roof. But we do know (because it is an isosolec(sp?) triangle) that the length of the roof is twice B. So lets set up out formula like this: (1.7)^2 + B^2 = (2B)^2 1.89 = 4B^2  B^2 1.89 = 3B^2 1.89/3 = B^2 ...now square root both sides. sqrt(1.89/3) = B the length of the roof is twiceB 2(sqrt(1.89/3)) = 2B = length of one side of the roof; after you get this number add the overhang of (50cm.) Make sense?

amistre64

Best ResponseYou've already chosen the best response.0Yes, If I did it correctly; I get 2(170)/sqrt(3) + 50 196.3 cm + 50 cm = 246.3 cm is the roofs length on each side. or 2.463 meters
