Answer:
1.09
Step-by-step explanation:
0.65 + Percentage increase =
0.65 + (68% × 0.65) =
0.65 + 68% × 0.65 =
(1 + 68%) × 0.65 =
(100% + 68%) × 0.65 =
168% × 0.65 =
168 ÷ 100 × 0.65 =
168 × 0.65 ÷ 100 =
109.2 ÷ 100 =
1.092 ≈
1.09
Answer:
18
Step-by-step explanation:
if AB : BC : AC is 3 : 4 : 2 and BC = 8 then AB = 6 and AC = 4
To calculate the perimeter of the triangle we add all side lengths up
4 + 6 + 8 = 18
1a. Split the larger piece(1/3) into half to show the two pieces
1b. Both are 3/6 or 1/2
2a. It shows 1/2 +1/4
2b.cut it so there are 3 1/4 pieces, so cut the 1/2 piece horizontally in the middle
2c. 2/4 + 1/4 = 3/4. 1/2 + 1/4 = 3/4
