Ok, so the answer is 80%. How I got this, I did the cross-product method. On one side, I did x/100, and the other, I did 720/900. And I multiplied 720 by 100, and got 72,000. And I also did 900 Times x, and got 900x. So, the new equation is 72000 = 900x. I divided 72000 by 900, and got 80, which is the percentage. (Picture of Cross-Product Method)

1/8 + 1/4

the least common multiple of 8 and 4 is 8. Convert 1/8 and 1/4 to fractions with denominator 8.

1/8 + 2/8

Because 1/8 and 2/8 have the same denominator, add them by adding their numerators.

1+2/8

add 1 and 2 to get 3

3/8 or 0.375

If the measure of arc FF=47 and the measure of angle ACD=55, determine the measure of arc BD. I really need help with this, than
Llana [10]

Answer:

  d.  8°

Step-by-step explanation:

It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.

EB and DA are diameters of circle Y. What is the measure of arc EDC?
Dmitrij [34]

Answer:

Option (D). 110°

Step-by-step explanation:

Since EB and AD are diameter,

m(\widehat{ECB}) = m(\widehat{ACD}) = 180°

m(\widehat{ECB})=m(\widehat{EDC})+m(\widehat{BC}) = 180° -------(1)

And m(\widehat{ACD})=m(\widehat{AB})+m(\widehat{BCD})

180° = 40° + m(\widehat{BCD})

m(\widehat{BCD}) = 140°

Since, m(\widehat{BCD})=m(\widehat{BC})+m(\widehat{CD})

2m(\widehat{BC}) = 140° [Given m(\widehat{BC})=m(\widehat{CD})]

m(\widehat{BC}) = 70°

From equation (1),

m(\widehat{EDC}}) = 180° - m(\widehat{BC})

m(\widehat{EDC}}) = 180°- 70°

Therefore, measure of arc(EDC) = 110°

Option (D) will be the answer.
