A school trip uses a 42-seater coach (excluding the driver's seat). 36 students, 3 teachers and 3 parents go on the coach. Each
tatyana61 [14]

Each student paid £4.25

Multiply number of students by amount paid:

36 x £4.25 = £153

Each parent paid twice as much: £4.25 x 2 = £8.50

3 parents x 8.50 = £25.50

Total paid: 153 + 25.50 = £178.50

178.50 is less than the coach ( 195)

ololo11 [35]

Answer:

24 buckets

Step-by-step explanation:

Given that :

Dimension of rectangular block = 45 m by 38 m

A bucket of paint will cover 72m² of floor

Total area of floor : Length * Width

Total Area = (45m * 38m) = 1710 m²

Buckets of paint required :

Total area / Area per bucket

= 1710m² / 72m²

= 23.75 buckets

= 24 buckets

A clock has a diameter of 16 inches. Which measurement is closest to the area of the clock in square inches? 804.25 in2 50.27 in
meriva

Answer:

200.96 in2

Step-by-step explanation:

Area of a circle = nr²

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

radius = 16 inches / 2 = 8 in

Area = 3.14 x 8² =  200.96 in²

A cylindrical container 30cm in diameter holds approximately 30 litres of oil. how far does the oil level fall after 1 litre of
LenaWriter [7]

The fall in the level of oil is <u>1.4147 cm</u> when the total volume of oil consumed is 1 liter.

We assume the drop in the level of water to be d cm.

Since the container is cylindrical in shape, its volume is given as:

V = πr²h, where V is the volume, r is the radius, and h is the height.

In the question, we are given that the diameter of the can is 30 cm.

Hence its radius = 30/2 = 15 cm.

The capacity of the container is given to be 30 liters or 30*1000 = 30000 cm³.

The volume of the oil used = 1 liter or 1*1000 = 1000 cm³.

Thus, substituting V = 1000, r = 15, and h = d, in the formula of the volume, V = πr²h, we get:

1000 = π(15)²(d),

or, d = 1000/(225π) = 1.4147.

Thus, the fall in the water level is 1.4147 cm.

Therefore, the fall in the level of oil is <u>1.4147 cm</u> when the total volume of oil consumed is 1 liter.
