Find the coordinates of the midpoint of the segment whose endpoints are given. W (-3,-7) and X (-8,-4)

(-5.5, -5.5)

Step-by-step explanation:

x =

= -5.5

y =

= -5.5

midpoint = (-5.5, -5.5)

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
