PLZ HELP ME ITS DUE RIGHT NOW woth 18 points
Anika [276]

Answer:

The answers to the first question are A,C,D

The answer to the second question is YZ=16

Step-by-step explanation:

(1st Question)

Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate.

You need to create the following equation to find the length of KN and MN 7x-4=5x+12

(Get the "x" variable to one side)

2x-4=12

(Isolate the variable)(Remove the 4)

2x=16

(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)

x=8 (Answer Choice)

Plug in the x value into each equation

KN= 7(8)-4

KN= 56-4

KN= 52

MN= 5(8)+12

MN= 40+12

MN= 52 (Answer Choice)

MN=KN

(Second Question)

Since XWY(20) is half of XWZ(40), ZWY also equals 20.

This now proves the triangle is congruent by the AAS postulate.

Since the triangles are congruent, if XY = 16, YZ also equals 16.

The probability of choosing a penny from the 1980s from the bag of pennies without looking is 3/40 . Which term best describes t
erik [133]

Answer: Unlikely

Step-by-step explanation:

Given: The probability of choosing a penny from the 1980s from the bag of pennies without looking=\frac{3}{40}=0.075

We know that the probability of any event lies between 0 and 1.

  • If probability of occurring event is 0 then the event is impossible.
  • If probability of occurring any event is 1 then the event certain.
  • If probability of occurring any event lies between 0.5 and 1 then the event is said to be likely.
  • If probability of occurring any event lies between 0 and 0.5 then the event is said to be unlikely.

Since, 0.075 lieas between 0 and 0.5, therefore the event is said to be unlikely.

Please hurry!! I have less than 5 min!!<br> What is the area of this composite shape?
vladimir2022 [97]

Area of the composite shape = 292 yd²

Solution:

The shape is splitted into two rectangles.

The reference image of the answer is attached below.

Length of the top rectangle = 21 yd

Width of the top rectangle = 29 yd – 22 yd = 7 yd

Length of the side rectangle = 29 yd

Width of the side rectangle = 26 yd – 21 yd = 5 yd

Area of the figure = Area of the top rectangle + Area of the side rectangle

                              = (length × width) + (length × width)

                              = (21 × 7) + (29 × 5)

                              = 147 + 145

                              = 292

Area of the composite shape = 292 yd²
