hi can someone answer this

Answers

Answer 1

40 ......................

Answer 2

Answer:

Step-by-step explanation:

When two angles are on the interior like that, they are adding up to 180 degrees in total.

So, x would be 20 because

2x+60=

2 times 20, plus 60 = 100

and 3x+20=

And 3 times 20, plus 20 = 80

Adding up 100 and 80, you get 180 degrees.

I hope this helps. I'm a student too but I hope I explained it relatively ok.

Answer:

t (is less than or equal to) 96

Step-by-step explanation:

to solve for t, you need it to be isolated. to move the 3 to the other side, you need to multiply it on both. 3 x t/3= t and 32 x 3= 96, therefore t (is less than or equal to) 96.

i hope this helps :)

Answer:

t ≤ 96

Step-by-step explanation:

t / 3 ≤ 32

(multiply both sides by 3)

t / 3 * 3 ≤ 32 * 3

t ≤ 96

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?

Answers

Answer: 0.71

Step-by-step explanation:

Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:

P(R) + P(C) = 1

0.29 + P(C) = 1

P(C) = 1 - 0.29

P(C) = 0.71

Therefore, the probability of a cup drink being cola flavour is 0.71.

Step-by-step explanation:

8x-12+104=180°

= 8x=180-92

= x=88/8

= x=11°

104=y

Answer:

Step-by-step explanation:

Angles (8x - 12) and 104 are "straight angles;" their sum is 180 degrees.

Therefore, 8x - 12 + 104 = 180, or 8x - 12 = 76, or 8x = 88.

Dividing both sides by 8, we get x = 11

Angles z and 104 are vertical angles and are thus equal to one another. Thus, z = 104 degrees

Answer:

105

Step-by-step explanation:

To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.

To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.
