To find the answer for this question you need to first understand that 3 angles of a triangle make up 180 degrees. To make a triangle you want to cut the shape down from the 82 degrees to the degrees X. You then will be left with angle Y, a 90 degree angle, and the angle cut in half (which would be 41). You add 41 to 90 to get 131, and subtract that from 180 to get 49 degrees as your angle Y. Hope this helped <3

34. A motorist started a journey at 10.25a.m. and ended at 6.15 p.m. Calculate the time
GenaCL600 [577]

Write the times for each hour from start time:

10:25 am

11:25 am

12:25 pm

1:25 pm

2:25 pm

3:25 pm

4:25 pm

5:25 pm

6:25 pm

There are 8 hours between 10:25 am and 6:25 pm.

they finished at 6:15 which is 10 minutes before 6:25 ( 25-15 = 10)

10 minutes less than a full hour is 50 minutes ( 60 - 10 = 50)

8 hours - 1 hour = 7 hours

7 hours + 50 minutes = 7 hours 50 minutes total time.

Three students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. L
Gennadij [26K]
If we start with 6 and 8, we can break 6 up into 2*3 and 8 into 2*2*2, thus getting a prime factorization of 2*2*2*2*3, or 2^4 *3.

If we begin with 4 and 12, 4 breaks into 2*2 and 12 into 2*2*3, so the prime factorization of 48 is still 2^4 *3.

The starting factors do not matter, since the answer comes out to be the same. There is exactly one correct answer- it doesn't matter how it's found.

Hope this helps! :)

Answer:  530.66 units²

<u>Step-by-step explanation:</u>

Area_{(circle)}=\pi r^2\qquad and\qquad r=\dfrac{diameter}{2}\\\\\\\implies Area_{(circle)}=\pi \bigg(\dfrac{diameter}{2}\bigg)^2\\\\\\\text{It is given that the diameter = 26:}\\A=\pi\bigg(\dfrac{26}{2}\bigg)^2\\\\\\.\quad =\pi \cdot 13^2\\\\\\.\quad =169\pi\\\\\\.\quad =\large\boxed{530.66}

Solve for y 3y^2=432
Andreas93 [3]

Answer:Each Y could equal 12

Step-by-step explanation:

You would divide each side of the equation y 3 to get y^2=144.

Next take the root of both sides to get y= ± 12

After that just separate the solutions and get 12.

(I hope this helps. I tried)
