I believe x would just be 4? There isn’t much information given so that’s my best guess.

Sam made 6 identical necklaces, each having beads and a pendant. the total cost of the beads and pendants for all 6 necklaces wa

Marizza181 [45]

Since six necklaces all together costs 31.80 to make, I divided 31.80 by 6 and got 5.3. That means that to make one necklace, they'd spend $5.30. The beads alone for 1 necklace cost $2.70, so I subtracted that from the $5.30.

Answer: Each pendant costs $2.60

How do you find 55% of 140?

yaroslaw [1]

If you type in calculator on google click the buttons and do 140 divided by 55% but the long way to do a percentage problem is to find 1% of the number you start off with and multiply it by the percentage so in this case 1% of 140 would be 1.4 and multiply that by 55 t

Х 30° Calculate the size of angle x. angle x = I

Furkat [3]

If one Angle is = 30

And the other two angles are equal

Given: x = l

ATQ

⇒30+x+l= 180

⇒x + x = 180-30

⇒2x = 150

⇒x = 150/2

⇒x = 75

Therefore x = 75

And the angles are 30, 75 and 75

N the diagram, point O is the center of the circle and mADB = 43°. If mAOB = mBOC, what is mBDC?

Sonja [21]

The answer is 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.
