A=1/2 bh for b i need help
qwelly [4]
You said that                      <u>  A = 1/2 b h</u>

Multiply each side by 2 :    2A  =  b h

Divide each side by 'h' :    <em>2A/h  =  b</em>

Estimate how much MORE water it would take to completely FILL the vase to the top?
MariettaO [177]

Answer:

81πinc^3

Step-by-step explanation:

Volume of glass = π(3)^2(12) = 108πin^3

Volume of water in glass = π(3)^2(3) = 27πin^3

Volume needed to fill completely = 108π - 27π = 81π^3

jennifer bikes 7 miles south and then turns to bike 13 miles east how far away is she from where she started?
Marina CMI [18]

Answer:

She is about 14.765 miles (\sqrt{218} miles) from where she started

Step-by-step explanation:

There is a relation between the three sides of the right triangle

  • The side opposite to the right angle is called hypotenuse and it is the longest side
  • The other two sides called legs of the right angle
  • The relation between them is: (hypotenuse)² = (leg1)² + (leg2)²

∵ Jennifer bikes 7 miles south

∵ She turns to bike 13 miles east

∵ South and East are perpendicular

→ That means the distance from her start point to end point represents

   a hypotenuse of a right triangle, whose legs are 7 and 13

∴  (hypotenuse)² =  (leg1)² + (leg2)², where

  • hypotenuse is the distance between her start and end points
  • leg1 is her distance in south direction
  • leg2 is her distance in east direction

∵ Leg1 = 7 miles

∵ leg 2 = 13 miles

∴ (hypotenuse)² =  (7)² + (13)²

∴ (hypotenuse)² = 49 + 169

∴ (hypotenuse)² = 218

→ Take √  for both sides

∴ hypotenuse = \sqrt{218}

∴ hypotenuse ≅ 14.76482306

∴ She is about 14.765 miles (\sqrt{218} miles) from where she started.
