Working out the question​

Mathematics
1 answer:
Blizzard [7]3 years ago
7 0

Answer: ∠AOB = 100°

Step-by-step explanation:

This is found in the circle geometry. The theorem in solving this stated that the angle which an arc of a circle subtends at the centre  of the circle is twice that which  it subtends at any point on the remaining part of the circumference of the circle

Therefore

∠AOB = 2 x ∠ACB

           = 2 x 50°

           = 100°

Help please<br>solve for x​
adoni [48]

Answer:

X = 60°

Step-by-step explanation:

the angle you are looking for is a corresponding angle to the angle given (121°)

2x + 1 = 121

121 - 1 = 2x

121 - 1 = 120

2x = 120

120/2 = 60

X = 60

Plz help solve, <br>velocity units are ft/min<br> ​
Alex Ar [27]

Answer:

t = 11 min

and

t = 18 min

Step-by-step explanation:

When we have unidimensional motion, the sign of the velocity defines the direction.

So we could say that a positive velocity like:

v = 4ft/min

Means that you are moving to the right with a speed of 4 feet per minute.

And a negative velocity like:

v = -3 ft/min

means that you are moving to the left with a speed of 3 feet per minute.

Then the bug changes direction when the velocity changes of sign.

In the graph, we can see that the velocity changes of sing in two points, these points are:

t = 11 min

and

t = 18 min

Last week Martha read two fifths of an adventure book and this week she has read
shutvik [7]

Answer: Check explanation.

Step-by-step explanation: If she has 140 pages left to read, and completed 2/5 of the book last week, and 1/4 of the book this week, then we have to divide the pages left to read (140) by the fraction of pages she read last week (2/5), and this week (1/4).

When you divide 140 by 2/5 by 1/4, you get 1400. Hope this helped!
