Answer:
$90000
Step-by-step explanation:
From the pie chart,
Let the total annual income = $y
The percentage of housing = 28 %
The percentage of clothing = 14 %
The combined percentage of housing and clothing = 28+14 = 42 %
If the amount spent on both housing and clothing combined = $ 37800
Therefore,
y(42/100) = 37800
Solve for y
42y = 37800×100
42y = 3780000
y = 3780000/42
y = $90000
Hence, the total annual income is $90000
The center of the given circle = (-4, 3)
So the center of the image = (-4, 3 -2(4) = (-4, -5)
So the equation of the image is
(x + 4)^2 + (y + 5)^2 = 9
Its choice 3.
Hey!
Well a soccer field would be a rectangle and if cut across you will be presented with two right triangles. So since you are presented with right triangles you will need to know at least two sides to determine the third. The formula used for right triangles is...
a² + b² = c²
Now a and b are the "legs" of the triangle meaning the two sides that come together to make a 90° angle. The c in the equation would be the hypotenuse of the triangle, otherwise the longest side or in this case the diagonal part. Now to find that distance you will have to plug in and solve...
100² + 230² = c²
10000 + 52900 = c²
62900 = c²
about 250.8 meters
Hope this Helped!
