Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
She will need 12 cups of pineapple juice.
Example: 4 x 4 = 16
3 x 4 = 12
Provide a picture of the tile, thanks!
P = 2(L + W)
510 = 2(L + W) ...divide both sides by 2
510/2 = L + W
255 = L + W
3/5(255) = 765/5 = 153 cm <== length
2/5(255) = 510/5 = 102 cm <== width
