What Is The Measure Of KMN?A. 29 DegreesB. 66 DegreesC. 53 DegreesD. 89 Degrees

Answers

Answer 1

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°

Answer 2

Answer:

B) 66

Step-by-step explanation:

75+39=114

180-114=66

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Micaela sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.

196 visitors purchased no costume.
108 visitors purchased exactly one costume.
22 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase more than one costume as a percent to the nearest whole number.

Answers

Answer:

7% chance

Step-by-step explanation:

the equation is (value/total value) x 100.

So I did (22/326) x 100

Which leaves you with 6.748 or about 7

Answer:

25.5m

Step-by-step explanation:

square area: 6m*3.5m = 21m

Triangle height: 5m - 3.5m = 1.5m

Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m

Total area: 21m + 4.5m = 25.5m

solve the equation -2(x-5)=-14

Answers

Answer:

x=12

Step-by-step explanation:

-2(x-5)=-14

x-5=-2/-14

x-5=14/2

x-5=7

x=5+7

x=12

X =12. Multiply it out. -2x +10= -14. -2x=-14-10. -2x= -24. Divide both sides by -2. Hope this helps!

Mrs. Chevalier’s class is reviewing by playing a math game. Mrs. Chevalier randomly selects an integer from the set of integers -15 to 15.

Part A

What is the probability that Mrs. Chevalier names a positive integer?

Part B

Explain how you determined your answer.

Answers

Answer:

(15/31) ?

Step-by-step explanation:

|-15| = 15

15+15+1 (for 0) = 31

1 through 15 are positive, so 15 of the 31 could be positive, or 15/31

Sorry, could be wrong, but I think it's right

Part A Answer: The probability that Mrs. Chevalier names a positive integer is a 50% chance.

Part B: Numbers from -15 to 15 is thirty-one total numbers including zero, but zero is neither negative nor positive, so it doesn’t really count in this situation unless the instructions describe it as positive. Without the zero, it is thirty numbers in total, with half of them being negative, and half of them being positive, which can also be said as 50%. You can find this answer by dividing 15 by 30, which is 1/2, or 50%.

Ms. Hendricks encourages her sixth-grade class to keep reading during breaks from school. She said that during a break lasting d days, they should each read 30d minutes in total. This year, spring break is 9 days long.
How many minutes should each student read during spring break?
Write your answer as a whole number or decimal.

Answers

I believe the answer should be 270.

You should replace the “d” in 30d with a nine because the “d” stands for how many days. The question said there are nine days so you would get this...

30x9=270 minutes in total

Step-by-step explanation:

So first off, if you are going left by 9. That means you will going back (aka negative 9 points).Also, since you are going left, only the x axis changes because left or right is what changes here.

Once you count back 9 spaces, or do 4-9, you will end up with negative 5(x value)

Your ending product is (-5,5)

Let a equal measure of a angle a. The equation 360ﾟ= a + 90ﾟ+ 135ﾟ+ 75ﾟ represents the sum of the angles in the quadrilateral. Find the missing angle measure by solving the equation.​

Answers

Answer:

A = 60°

Step-by-step explanation:

First to find the missing angle you add the three known angles,

90 + 135 + 75 = 300

Then, you subtract, 360 - 300 = 60

So, 360° = 60° + 90° + 135° + 75°

Answer:

A = 60 percent
