Answer:
Part A-4.6 miles.
Part B-2.1
Step-by-step explanation:
1.7^2 + 4.3^2 = c
c=4.6
Part A) The length of a straight line between the school and the Fire Station is 4.6
Part B) The length of a straight line between the school and the hospital is 2.1
(Work for part B screenshot didnt save right so here's a link to a similar question that has similar work to mine :) )

Answer: £30.20
We can say, 4kg of copper is mixed with 1kg of Zinc to make 5 kg of brass.
So to make 7 kg of brass we need to find out how much kg is copper and zinc mixed. Just increase one kg in both the weight, 5kg of copper and 2kg of zinc makes it 7kg of brass. (Technical thinking)
Now that we know the proportions of the metals so find out the costs of each kg of it.
Copper: 1 kg costs £5
5kg costs- 5*5 --> £25
Zince: 1 kg costs £3.20
2kg costs- 3.20 * 2 --> £5.20
Now add them, £5.20 + £25 --> £30.20
So, the cost of 7kg of brass is £30.20
Answer:
The answer to your question is: the points are not collinear.
Step-by-step explanation:
Data
AB = 7
BC = 4
AC = 9
Are points A,B and C collinear?
If they are collinear, the distance from AB plus the distance BC must be equal to the distance AC.
Process
dAB + d dBC = d AC
7 + 4 = 9
11 = 9
The distances are different so they are no collinear
Answer:
Step-by-step explanation:
The axes x and y are calibrated in 0.25
If the circle is carefully considered, the radius r of the circle is:
r = -1.25 - (-2)
r = 0.75 units
The equation of a circle is given by:
The center of the circle (a, b) = (-2, -2)
Substituting (a, b) = (-2, -2) and r = 0.75 into the given equation:
