Answer:
£12000
Step-by-step explanation:
Granddaughter -- 1/2 of x
Grandson -- 1/2(1/2 of x)
Brother -- 1/6 of x
Dogs' home -- £1000
Therefore,
x = 12000

An equilateral triangle has all side lengths the same, and all angles are 60 degrees. Using this we can split the triangle along its altitude to get two right triangles with a hypotenuse of length 10 and a base of 1/2 of the original length, so 5. Now we can either use the Pythagorean theorem (a^2+b^2=c^2) or the fact that it is a 30 60 90 triangle (angles measure at 30 60 and 90 degrees) Pythagorean theorem is probably easier.
It stated that the squares of the two legs of a right triangle add to the square of the hypotenuse. So a(the altitude)^2+5(the base)^2=10(the hypotenuse)^2
A^2+5^2=10^2
A^2+25=100
A^2=75
A=sqrt(75)
A=5*sqrt(3)
Final answer:
The altitude of an equilateral triangle with side length 10 is 5sqrt(3), or about 8.66
Answer:
7
Step-by-step explanation:
The equation of direction variation is
y = kx where k is the constant of variation
y = 7x so 7 is the constant of variation
<em>Option A.</em>
<em>The reasoning behind my answer is that you would be getting a large and random group of students meaning that they have many different people and not a specific group of people. Randomly choosing also gives a chance of getting all grades meaning that it wouldn't just be one specific grade of which was surveyed.</em>
