Answer:
Step-by-step explanation:
We can use pytho theorem to find X because its a right triangle, so:
a^2 + b^2 = c^2
plug our numbers
1^2 + 1^2 = x^2
simplify
1+1 = x^2
2=x^2
answer = root2
Plzzz helppppppp meee

Answer:
Circumference of the smaller circle = 2.1x units
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Two similar circles are shown. The circumference of the larger circle, with radius OB, is 3 times the circumference of the smaller circle, with radius OA. Radius OB measures x units. Which expression represents the circumference of the smaller circle with radius OA ?
Radius of the larger circle OB = x units
Radius of the smaller circle OA = y units
Circumference of larger circle = 2πx units
Circumference of smaller circle = 2πy units
Since circumference of larger circle is 3 times the circumference of smaller circle,
2πx = 3(2πy)
2πx = 6πy
x = 3y
y =
Therefore, circumference of the smaller circle = units
= units
= 2.094x
≈ 2.1x
Circumference of the smaller circle circle = 2.1x units
Answer:
x+y=200
xy=9,600
Step-by-step explanation:
The diagram shows rectangular parking lot with sides of x feet and y feet.
1. The area of the rectangle is given by
A=Length \times Width
A = xy -------------------------(1)
We are given that the area of the parking lot is 9,600\ ft^2, then
eq(1) becomes
9,600 = xy ---------------------(2)
2. A parking lot has a 200ft fence built along two adjacent sides of lengths x and y, then
Then the perimeter of the two adjacent sides
x+y=200 ---------------------------------(3)
Thus ,The system of two equations are
x+y=200
xy=9,600
