Answer:

  x = 115

Step-by-step explanation:

The sum of angles in a hexagon is 720°.

  x +118 +90 +112 +131 +154 = 720

  x = 115 . . . . . . . subtract 605

Answer:

C

Step-by-step explanation:

Because lets say we have a point (1,2)

when reflecting this point over the y-axis it becomes (-1,2) so only the sign of the X value changes. Therefore by writing the system f(x)=g(-x) it changes the X value.

plato / edmentum answer

Given:

The side lengths of two cubes are 2.5 yd and 2 yd.

To find:

The side length of third cube.

Solution:

From the given figure it is clear that the cubes are inclined to each other in such a way so that they form a right angle triangle and side length of third cube is the base.

Let x be the side length of the third cube.

Using Pythagoras theorem, we get

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

[tex](2.5)^2=(x)^2+(2)^2[/tex]

[tex]6.25=x^2+4[/tex]

[tex]6.25-4=x^2[/tex]

[tex]2.25=x^2[/tex]

Taking square root on both sides, we get

[tex]x=\pm\sqrt{2.25}[/tex]

[tex]x=\pm 1.5[/tex]

Side cannot be negative. So,

[tex]x=1.5[/tex]

Therefore, the side length of the  third cube is [tex]x=1.5[/tex] yd.

Answer:

total outcomes= 8

green = 3

probability to get green = 3/8 = 0.375

Answer:

120 groups

Step-by-step explanation:

Total number of players = 12

Number of superstars = 2

To select a group of 5 players that MUST include the two superstars can be done in how many different ways?

Since the two superstars must always be in the 5 player team

Number of players left to choose = 5 - 2 = 3

Number of players from which selection is to be made = 12 - 2 = 10

Hence, the number of ways of choosing 3 players from 10 ; 10C3

Recall ;

nCr = n! / (n-r)!r!

10C3 = 10! ÷ (10-3)!3!

10C3 = 10! ÷ 7!3!

10C3 = (10*9*8) / (3*2*1)

10C3 = 720 / 6

10C3 = 120 groups

Answer: The air temperature increases about 10 degrees C for every 1000-meter increase of altitude.

Step-by-step explanation:

Ur welcome :)

The correct statement is The air temperature increases about 10°C for every 1000-meter increase of altitude.

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

according to the given plot we have

The air temperature at the base of the mountain is about 18°C is false because  air temperature at the base of the mountain is about 20°C.

The air temperature at the base of the mountain is about -22°C false because  air temperature at the base of the mountain is about 20°C.

The average temperature on top of the mountain is about -2°C is false because it is not mentioned in the graph.

The air temperature increases about 10°C for every 1000-meter increase of altitude is true.

Answer:

The points are 1 unit apart.

Step-by-step explanation:

Given points are:

(3.1,-1) and (4.1,-1)

Distance formula is given by;

Distance between points = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where,

[tex](x_1,y_1)[/tex] = Coordinates of first point

[tex](x_2,y_2)[/tex] = Coordinates of the second point

Putting the values,

Distance = [tex]\sqrt{(4.1-3.1)^2 + (-1-(-1))^2[/tex]

Distance = [tex]\sqrt{(1)^2 + (-1+1)^2[/tex]

Distance = [tex]\sqrt{(1)^2}[/tex]

Distance = 1 unit

Hence,

The points are 1 unit apart.

Answer: I would say B would be the answer Because....

Step-by-step explanation:

if about 20 to 23 cars pass through every 26 minutes, and haw many cars pass by in 156 minutes...

26 x 6 = 156

6 x 20 = 120  

6 x 21 = 126

6 x 22 = 132

6x 23 = 138

all thoes numbers are around B.

Answer:

$1.46

Step-step explanation:

We have to find out what 6.5% of 22.5 is, our keyword is of, so we're multiplying. Our equation is:

22.5 x 0.065 = 1.46

So our tax is $1.46

Answer:

8, 14

Step-by-step explanation:

Any term in a Fibonacci sequence is found as

[tex]a_{n}[/tex] = [tex]a_{n-2}[/tex] + [tex]a_{n-1}[/tex]

Thus

a₃ = a₁ + a₂ = 2 + 6 = 8

a₄ = a₂ + a₃ = 6 + 8 = 14

The next 2 terms are 8, 14

Answer:

8, 14

Step-by-step explanation:

In a general Fibonacci sequence, any number in the sequence after the first two is the sum of the previous two. Here, we get the 3rd term by adding 2 and 6 to get 8, making our sequence

2, 6, 8

To get the fourth, we repeat the process, adding 6 and 8 to get 14:

2, 6, 8, 14
