5. no because each spinner is not the same size. it's not divided equally. 6. yes because a cube has 6 faces, so 1 on each is even. 7a. 12% 8. the bag with 25 tiles has a 40% chance of blue tiles and the bag with 250 tiles has a 30% chance, so the chances of picking a blue tile from the 250 tile bag is lower

Answer:

5 and 6 look down.

7. 12%

8. 75/250 30%

Step-by-step explanation:

5. The spinner shown is not a fair spinner because sections 1 and 5 are bigger than the rest of the sections.

6. The cube is fair because you have a 1 in 6 chance of getting a number. There is not a greater chance to roll a 1 than a 4.

7. There are 3 marbles that are white out of 25. This means that the probability of getting a white marble is a 3/25 chance.

There is a 12 percent chance that you will pick a marble

8. In this problem you are doing the same thing as 7. 10/25 is 40% chance and 75/250 is 30% chance.

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)

Answer:

Step-by-step explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 +  576 = 900²

c² =810000

c= [tex]\sqrt810000[/tex] = 900

c=900ft

Answers

Answer:

x= 22.6

Step-by-step explanation:

This little red square means that is a right angle (90 degrees)  

x is the complementary of 67.4  (Both add to 90)

90-67.4 = 22.6

that type of corner angle is a 90° angle, so since you know the first half of the 90° angle which is 67.4 all you need to do is subtract

so you get
90 - 67.4 = 22.6

g(x) = x^3 − x^2 − 4x + 4
g(x) = x^3 + 2x^2 − 9x − 18
g(x) = x^3 − 3x^2 − 4x + 12

Find the measurement of one of the vertical angles .

Answers

Answer:

x = 15 degrees, one vertical angle is 165 degrees

Step-by-step explanation:

3x = x + 30

3x - x = 30

x(3-1) = 30

2x=30

x=15

All the angles need to add up to 360 degrees.

15 + 15 + 2y = 360

2y = 330

y=165
