Answer:
£32.50
Step-by-step explanation:
my first question to the teacher : so, no windows in the living room ?
so, it is a square living room with 5.5 m side length.
but each wall is a rectangle of 2.2 × 5.5 m.
for one wall we have to deduct a door area of 1.8×0.9 m.
so, one wall
2.2 × 5.5 = 12.1 m²
4 walls
4 × 12.1 = 48.4 m²
minus one door area
1.8 × 0.9 = 1.62 m²
48.4 - 1.62 = 46.78 m² total paint area
1 L paint covers 8 m².
so, we need 46.78/8 = 5.85 liters.
she gets the paint in 2 L tins. so, she needs 3 tins (6 L).
each tin costs £13.
and because she buys 3 tins, she gets the third one for half the price (13/2 = £6.50).
so, she has to pay
2×13 + 6.50 = 26 + 6.50 = £32.50

A
Step-by-step explanation:
i think
61,62,63 because 61 and 63 came before and after 62
Answer:
120 ohms
Step-by-step explanation:
Given data
Voltage= 60 volts
Current= 0.5 amps
Power of bulb= 60 watt
We know that from Ohms law
V= IR
Make R subject of the formula
R= V/I
R= 60/0.5
R= 120 ohms
Hence the resistance is 120ohms
Jenna has more.
If Max gives 16 cards to Jenna, then he has 16 cards less. 20-16=4... Max has only 4 cards left.
Similarly, because Jenna gains 16 cards, 50+16=66. Thus Jenna has 66 cards.
If Max has 4 cards, and Jenna has 66, Jenna clearly has way more.
Hope that helps :))<span />
