Answer:
1.44 pounds
Step-by-step explanation:
From the above question, we are told that:
The shop has 3 for 2 offer on chocolate bars going on .This means a customer can buy 2 chocolates get 1 free, for the price of 2 chocolates, a customer can get 3 chocolates.
If the price of 1 chocolate bar = 72p
2 chocolate bars =
72p × 2
= 144p
Hence, Sian spends 144p
We are asked to convert our answer to pounds
The symbol p represent pence in money form
Hence,
100p(pence) = 1 pound
144p(pence) = x
100p × x = 144p × 1
x = 144p/100p
x = 1.44 pounds
Therefore, Sian spends 1.44 pounds
Answer:
The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )
Step-by-step explanation:
Given equation as :
3 x² + 6 x +15 = 0
The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as
x = 
So , from given eq , the value of x is now obtain as
x = 
Or, x = 
Or, x = 
∴ x = ( - 1 + 2 i ) , ( - 1 - 2 i )
Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i ) Answer
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
240 is 240% of 576
240% x 240 = x
(240 x 240) divide by 100
57,600 divide by 100 = 576
x = 576
D. 3 to 5
This is because if you simplify the ratio by dividing each number in the ratio by 4, therefore for every group of 5 birds 3 of them are parrots
