For 30 points. hurry got till 9 gina was given an irregularly shaped piece of metal and was told that the density of the metal was 12 g/cm3. she measured the mass of the piece to be 276 g. what was the volume of the piece of metal gina was given? a. 23 cm3 b. 264 cm3 c. 288 cm3 d. 3,312 cm3

A. 23 cm3

Step-by-step explanation:

V= mass ÷ density

12 g/cm3 is the density

276g is the mass.

So, 276 ÷ 12

= 23 cm3

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
