The answer is 257.08m. Explanation: you know that one side of the square in the middle is 50m. This is the same as the diameter of one of the half circles on each side. The perimeter of a circle is the formula C=2(pi)r, where r is the radius. Dividing 50 by two will get you the size of the radius, then just plug it into the equation to find the perimeter of both rounded sides (a full circle). The two circular sides equal 157.08m, so then you just need to add the flat sides, which are both 50m since they’re congruent. 157.08m + 50m + 50m = 257.08m, so the perimeter of the shape is 257.08m.
Answer:
The correct answers are x + y = 5600 and x - y = 700.
Step-by-step explanation:
Write a system of equations in x and y describing the situation. Do not solve the system.
Keiko has a total of $ 5600, which she has invested in two accounts.
Let x be the amount of money in the larger account and y be the amount of money in the smaller account.
So, Keiko has invested her $5600 in two accounts x and y.
Thus x + y = 5600.
Also, given by the problem, the larger account (x) is $ 700 greater than the smaller account (y).
Thus x - y = 700.
Thus the two system of equation in x and y describing the given situation are
x + y = 5600 and x - y = 700
Answer:
The quadrilateral is Parallelogram.
Step-by-step explanation:
A quadrilateral is a four-sided regular polygon.
A parallelogram is a quadrilateral.
The opposite sides of a parallelogram are parallel and equal in length.
The opposite angles of a parallelogram are also equal.
In this case the quadrilateral is defined as follows:
- two angles that each measure 60°
- two angles that each measure 120°
- Only two of the sides have a length of 3.2 inches.
Consider the quadrilateral ABCD below.
The quadrilateral ABCD is Parallelogram.
