The Hudson high school wrestling team just won the state tournament and have been awarded a triangular pennant to hang on the wa
Eduardwww [97]

Answer:

3 feet.

Step-by-step explanation:

  • Base of the  triangular pennant = 1.5 feet long.
  • Area of the triangular pennant = 2.25 Square feet.

Now, we know that:

Area of a Triangle=\frac{1}{2}$ X Base X Height

Substituting the given values, we have:

2.25=\dfrac{1}{2}$ X 1.5 X Height\\\\2.25=$\dfrac{1.5}{2}$  X Height\\\\Cross multiply\\\\2.25*2=1.5  X Height\\\\Divide both sides by 1.5 to solve for the height\\\\\dfrac{2.25*2}{1.5}=\dfrac{1.5  X Height}{1.5}\\\\$Height of the Triangle =3 feet

Therefore, the height of the pennant is 3 feet.

After spending $30 on a dress, Mary had 3/8 of her money left. How much money did she have at first?
BaLLatris [955]
The answer is that she had 48.  Set it up as an equation with x as the amount of money she started with.  x - 30 = 3/8x.  That says, in words, "the amount of money she started with minus 30 for the dress left her with 3/8 of the money she started with.  Solve for x by adding 30 to both sides and subtracting 3/8 from 8/8x (8/8 = 1).  8/8 - 3/8 = 5/8, so 5/8x = 30, multiply both sides by 8 to get 5x=240 and x = 48.
