Answer:
Total voucher value is 1352
Step-by-step explanation:
X eqals voucher amount
Sam money 1/2x - 35
Jack money 1/2x - 78
Both 1239 = 1/2x - 35 + 1/2x - 78
1239 = x - 113 /+113 both sides
<u>1352 = x</u>
Answer:
52 m²
Step-by-step explanation:
12x3 = 36
2 x (11-3) = 2x8 = 16
36+16 = 52
Tanα=y/x
α=arctan(y/x), we are given the point (3.2, 6.2) so:
α=arctan(6.2/3.2)°
α=arctan(1.9375)°
α≈62.7° (to nearest tenth of a degree)
If there are 8 rows, there would have to be 6 in each row to make 48 (8x6=48).
If there had to be 6 white tiles in each of the 8 rows, than 6 out of 6 tiles would be white.
Therefore there would be 0 purple tiles.
