In the diagram, point O is the center of the circle and mADB = 43°. If mAOB = mBOC, what is mBDC?A) 45°
B) 43°
C) 41°
D) 37°
E) 33°

Answers

Answer 1

Answer: The answer is B) 43°
Angle ADB is an inscribed angle which means arc AB has an angle twice that of angle ADB. The angle of the arc would be the same as that of the central angle AOB. So, mAOB = 86°. And since, mAOB = mBOC, then mBOC = 86° and arc BC has a measure of 86° as well. Angle BDC intercepts the arc BC which means half of the angle of arc BC is mBDC. So, mBDC = 43°.

Answer 2

Answer:

It is B 43. This is correct for sure.

C. 20,160 shirts cost money
D. The total cost of shirts is 20,160

Answers

Answer:

option B is correct option.

Step-by-step explanation:

Explain what the point (20,160) represents in the context of the situation? Check all boxes that apply

Looking at the graph we come to know that 20 shirts cost $160 because x -axis represent number of shirts and y-axis represent Total Cost

So, the point(20,160) means x = 20 and y=160

We have 20 shirts and the cost is $160

So, option B is correct option.

On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Answers

Answer:20

Step-by-step explanation:

Given Wind speed is 2 mile/hr

Let jamie speed be x km/hr

Also she covered 44 miles with wind in time t

$44=\left ( x+2\right )t$

Against the wind

$36=\left ( x-2\right )t$

divide the two equations

$(44)/(36)=(x+2)/(x-2)$

11x-22=9x+18

x=20 miles/hr

It is 40 because it gives you the even rate inbetween each of them

Martha has $180. she needs a total of $20000 to start an account. she earns $60 per day working, of which she saves $50. which equation can she use to determine the number days,d, she needs to work to reach her goal of $20000.

Answers

$180+ 50x = 20000$

she has 180 dollars to start off with so you want to add that to the total cost. Then she makes 60 a day sbyt only actually saves 50 of it so +50x (thats the way i see it. The way they put it in the question is questionable. Dont know if she puts off the 50 or the 10)

The amount she started off with + how much she saves from working per day = total amount she needs

$180+ 50x = 20000$
