Answer:
£1.80/kg
Step-by-step explanation:
The total spent on apples and pears is £12.70, and this is the sum of the costs of the apples and the pears respectively:
£12.70 = (unit cost of apples)(2 kg) + (unit cost of pears)(7 kg), or
£12.70 = (unit cost of apples)(2 kg) + (£1.30/kg)(7 kg).
Solving for (unit cost of apples)(2 kg), we get £12.70 - (£1.30/kg)(7 kg), or:
(unit cost of apples)(2 kg) = £12.70 - £9.1 = £3.60
Solving for (unit cost of apples), we divide both sides by (2 kg), obtaining:
£3.60
(unit cost of apples) = ---------- = £1.80/kg
2 kg

In this question, the graph file is missing which is defined in the attached file please find it.
When YZ and XW were identical,
Because the angles are all 180 degrees in either a triangle:
We have 20 chances out of 100 which is 20/100=1/5 other known as 1 in 5 chance
The even numbers are 2, 4, 6, .., 100. 50 chances out of 100 which is 50/100=1/2 other know as 1 in 2 chance

Answer:
Cyclinder = 572.56 cm³
Sphere = 381.70 cm³
Cone = 190.86 cm³
Step-by-step explanation:
Here, the manager ordered for three different shapes, which are: a sphere, cylinder and a cone. We are told to find the volume of each.
For the cylinder:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cylinder is:
V = Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = 63.62 * 9
V = 572.56 cm³
For sphere:
Given:
Radius, r = 4.5 cm
Formula for volume of a sphere is:
= 381.7 cm³
For cone:
Given:
Radius, r = 4.5 cm
Height, h = 9 cm
The formula for calculating the volume of a cone is:
V = ⅓ * Base * height
Where base = πr²
= π * 4.5² = 63.62
Therefore,
V = ⅓*63.62 * 9
V = 190.86 cm³
Therefore the volume of perfume each bottle can carry is:
Cyclinder = 572.56 cm³
Sphere = 381.7 cm³
Cone = 190.86 cm³
Only one, if you want to know the measurement of the other side use the cosine law and to know the other angles use the sine law :)
