Answer:
a) 26 tickets
b) £5
c) chips, pastie and a soft drink
Step-by-step explanation:
Given:
- Price of one ticket = £7.50
- Total available to spend = £200
<u>Part (a)</u>
Greatest number of tickets = total available to spend ÷ cost of one ticket
= 200 ÷ 7.5
= 26.66666...
= 26 tickets
(We can't round up, as 27 tickets would cost £202.50)
<u>Part (b)</u>
Money left = Total available spend - cost of 26 tickets
= 200 - (26 × 7.50)
= 200 - 195
= £5
<u>Part (c)</u>
Cost of 3 items = £10 - change
= £10 - £4.70
= £5.30
One of the items can't be a burger, as £5.30 - £3.50 = £1.80
and £1.80 is not enough to buy 2 items.
If he buys chips, he has: £5.30 - £2.40 = £2.90 left to spend on the other 2 items.
Pastie + Soft Drink = £1.60 + £1.30 = £2.90
So he can buy: chips, pastie and a soft drink
To solve this, we'll use Euler's Polyhedral formula.
This formula states that in any polyhedron, the number of vertices V, faces F, and edges E, satisfy:
If we solve for the edges E, we'll get:
Using the data given,
We get that the polyhedron would have 12 edges
Answer:
The range consists of only one element, the number 8
Range = {8}
Step-by-step explanation:
Notice that the relationship requires as domain the first 4 even numbers.
That is, the numbers 2, 4, 6, and 8
Domain = {2, 4, 6, 8}
the relationship requires those numbers of the domain that are larger than 7.
There is clearly only one number that satisfies such relationship. Therefore, the only element of the Range is the number "8".
Range = {8}
