Answer:
48 in
Step-by-step explanation:
The diagonal of the inscribed square equals the diameter of the circle.
1. Calculate the diagonal of the square
d = 2r = 2 × 6√2 in =12√2 in
2. Calculate the side of the square
∆ACB is an isosceles right triangle.
We can use Pythagoras' Theorem to calculate the length of a side s.
3. Calculate the perimeter of the square
P = 4s = 4 × 12 in = 48 in
The perimeter of the square is 48 in.
Answer:
9 in approx
Step-by-step explanation:
Step one:
given data
the shape of the satellite dish takes the form of a paraboloid.
the diameter of the dish is 38in wide
and 10 inches deep.
step two:
The expression for the paraboloid is
where y is the vertical axis of the paraboloid
a is vertex to focus.
and x is the radius of the dish
x= 38/2= 19in
substituting we have
divide both sides by 40
vertex to focus= 9 in approx
Answer:
2nd one
Step-by-step explanation:
1/2 when multiplied with 3/3 so it has the same denominator is 3/6, the second choice shows 3/6 as a model as well as 5/6 so yea
50 + .35x = 75 + .25x
.1x = 25
25 divided by .1 is 250
going back and checking my work:
50 + .35 (250) = 137.5
75 + .25(250) = 137.5
So the answer is 250 miles
Answer:
i am pretty sure its 1
Step-by-step explanation:
when you look at x and y and where the line intersects the y axis if it where x and y it would be (1,1/2)
