Answer:
A⊥X
Step-by-step explanation:
Since
A is perpendicular to Y
A⊥Y
And, X is parallel to Y
X || Y
Which means that they have the same slope (same inclination)
That implies that A must be also perpendicular to X
A⊥X
Pretty sure all of them can be a linear function since they all graph out to be a line..
The definition of a linear function can be shown through this formula: y=ax+b
The trapezoid has two right triangles each with one side of length (13-9)2 = 4/2 = 2.
The other side of each right triangle is such that tan 60° = Heigth / 2
Then height = 2*tan60°.
The area of the trapezoid is height * (base 1 + base 2)/2
Then area = 2*tan (60°) * (13+9)/2 = 38.11
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
