Which of the following segments is a radius of OK?<br> ОА. АМТ<br> ОВ. Вт<br> Ос. AMR<br> O D. KM
FrozenT [24]

Answer:

A) TA

Step-by-step explanation:

A radius goes from the center of a circle to the outside edge.  

RP connects two points on the outside edge of the circle without going through the center.  This is not a radius.

TR connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

GP connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

TA connects the center of the circle to the outside edge.  This is a radius.

If y=27 when x= 8 find y when x =11
Rina8888 [55]

Answer:

37 1/8

Step-by-step explanation:

The problem probably assumes direct variation

y=kx

IF so, then plug in the values and solve for k

27=k(8)

k = 27/8

y= (27/8)x.  Now let x = 11

y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8

y = 37 1/8

the problem is making some assumption about the relation between x and y.  The simplest assumption that's likely is direct variation,  that x and y are linearly related.  The graph is a straight line through the origin with slope = 27/8

Need help with this question asap!!
Juli2301 [7.4K]

So I took the test and my teacher said to label all of the degrees so

angle 1,3,5,7,9,11,13,15 all = 95 degrees

angle 2,4,6,8,10,12,14,16 all = 85 degrees

I know 1 and 3 are vertical angles

3 and 8 are same side interior angle

4 and 14 alternate interior angles

6 and 12 are alternate exterior angles

13 and 9 are corresponding angles

4 and 7 are same side interior angles

I believe these are correct but you might want to double check with some other source
