Answer:

  66°

Step-by-step explanation:

The applicable angle relations are ...

An exterior angle of a triangle is equal to the sum of the remote interior angles. Vertical angles are congruent.

__

We recognize that angle HIJ, marked 105°, is an exterior angle to triangle DIJ. We also recognize that the angle marked x° is a vertical angle to angle DJI in triangle DIJ. Angles JDI, marked 39°, and DJI are remote interior angles with respect to angle HIJ.

We can use the relations described above to say that ...

  ∠HIJ = 39° +∠DJI

  39° +x° = 105°

  x° = 66° . . . . . . . subtract 39°

The measure of angle x is 66°.

the answer would be 66 degrees

Answer: 6 more games

Step-by-step explanation:

Let’s review what we know:

The red team’s probability of winning is 70% (0.7).The blue team’s probability of winning is 65% (0.65).There are a total of 120 games.


To find the amount of games each team will statistically win, we multiply the percentage by the number of games.


Red Team: 0.7 x 120 = 84 games.

Blue Team: 0.65 x 120 = 78 games.


84 - 78 = 6 games.
Therefore, the red team will statically win 6 more games than the blue team.

Answers

The number of the blue leashes will be 240.

What are linear equations?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

It is given that:-

A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.

The number of the blue leashes will be calculated as:-

L     =    320

B   +    P   +   g   =   320

{ (320  x   0.3 ) } + 0.7 ( B  +  g ) =  320

( 96 )  +   ( 2.8g )   =   320

2.8g   =   320 / 96

g   =   222  /  2.8  =  80

Now  B  =   3  x  g

B   =   3   x   80

B   =   240

Therefore the number of the blue leashes will be 240.

Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.

Answers

Answer:

Unit Cubes = 125 in

Volume = 125 in

Step-by-step explanation:

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

Volume of rectangular prism = length x width x height

Advance explanation:

The formula to find the volume of the rectangular prism is this:

L x W x H = V

L = Length = 5 in

W = Width = 5 in

H = Height = 5 in

V = Volume = 125

You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In

Hope this helps!

Summarized Steps:

Multiply the Length and Width with the Height (L x W x H).Your answer will be the result of the equation.

A student took 5 test in a quarter 3. His average was a 88. Four of his test scores were 87, 94, 86, and 100. What was his last test score? ( statistics) ( please write down or type it out! ) ty

Answers

Answer:

The last test score should be 73

Step-by-step explanation:

[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]  

Add all the values in the parentheses together to get:

[tex]88 = \frac{367 + X}{5}[/tex]

You want to remove the 5 next, so you multiply both sides by 5.

[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]

[tex]88 * 5 = 440[/tex]

You should get:

[tex]440 = 367 + x[/tex]

The last step is to subtract both sides by 367:

[tex]440 - 367 = 73[/tex]

[tex]X = 73[/tex]

I solved this by:

Please help

Answers

Answer:

x = 35° and y = 72.5

Step-by-step explanation:

The value of x = 35° {because they are vertically opposite angles )

Now, the the value of y

=> y + y + 35° = 180° { sum of angles on a straight line is 180° }

=> 2y + 35 = 180°

=> 2y = 180 - 35

=> 2y = 145

=> y = 145/2

=> y = 72.5

x is 35, because of the it’s the other ones vertex.
y is 72.5, because it’s a line and 180-35 is 145 and then divide it by 2 which is 72.5.

A weather forecast states that there is a 20% probability of rain on each of the next 3 days.

of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.

Answers



answer: The experimental probability that it will not rain on any pf the next 3 day is 64/125


The probability of raining is 20%
Hence, the probability that there will be no rain, is (100-20) = 80%
The probabilty that there is no rain on the first day is 80/100 = 4/5


Hence, the required probaility is (4/5)3 = 64/125
