Sean is his dad build a tiled walkway in their backyard. the walkway will be 69 feet long and 2 feet wide. the local hardware store sells tiles which are 2 by 2 feet and come in boxes of 6. how many boxes of tiles do they need?

First we should figure out how many times 2 goes into 69,(because each tile is 2 feet long) and I am going to do that by dividing 69 by 2. I got 34.5, so we can just say 35 to make it easier. So we now know we need 35 tiles, but they come in boxes of 6, so we will need to divide 35 by 6. It didn't make a full number (it was 5.833) but we need a full number of tiles so we will round up.

Our final number of how many boxes of tiles is 6.

Area walkway = 69 × 2 = 138 feet^2
1 tile = 4 feet^2
4x = 138
138 ÷ 4 = 34.5 tiles (needs 35 tiles)
1x = 6
x = 6 (1 box have 6 tiles)
6y = 34.5
34.5 ÷ 6 = 5.75(needs 6 boxes)

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
