Good evening
Answer:
<em>a) the cost of one apple is €</em><em>0.9</em>
<em>b) the cost of one pineapple is €</em><em>5.4</em>
<em>c) the cost of two pineapples and six apples is €</em><em>16.2</em>
Step-by-step explanation:
Consider P the price of a pineapple
A the price of an apple
A pineapple costs six times as much as an apple means P = 6A
Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20
then
6A + 2A = 7.20
then
8A = 7.20
then
A = €0.9
Since P = 6A then P = 6×(0.9) = €5.4
the cost of two pineapples and six apples
= 2P + 6A
= 2P + P
= 3P
= 3×(5.4)
= €16.2
Answer:17/18
Step-by-step no explation
1.6m=-4
Divide both sides by 1.6 to get m by itself
1.6m/1.6=-4/1.6
m=-4/1.6
m=-2.5
Answer: m=-2.5
If this is square So,
area of the shaded region = area of square - area of circle r=1/2 × 7 = 3.5
= (S×S) - (Pi × r^2)
= (7×7) - (3.14 × (3.5)^2 ) = 10.535 cm
