In quadrilateral qrst, qs=rt. is qrst a rectangle

We cannot determine whether the quadrilateral QRST is rectangle or not.

Step-by-step explanation:

A quadrilateral has four vertices. It may by square, rectangle, trapezium, parallelogram, rhombus, etc.

In quadrilateral QRST, QS and RT are diagonals of QRST.

It is given that the diagonals are same.

The diagonals of square, rectangle, isosceles trapezoid are same. Therefore by given information we cannot say that the quadrilateral QRST is a rectangle.

The different quadrilaterals are shown in below figure and these quadrilaterals have congruent diagonals.

Therefore if the diagonals are same then the quadrilateral may or may not be rectangle.

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
