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.

Vesna [10]

Let time be t , distance be d

160t=d-(1)
230t=210-d-(2)

Put value in eq(2)

$\\ \rm\longmapsto 230t=210-(160t)$

$\\ \rm\longmapsto 70t=210$

$\\ \rm\longmapsto t=30min$

Lauren predicts she will take 129 photos during vacation. If Lauren actually takes 111 photos, what is Lauren's percent error? R

Vera_Pavlovna [14]

Answer:

Lauren's percent error = 13.95% Approx

Step-by-step explanation:

Given:

Number of photos predict = 129

Number of photos actual = 111

Find:

Lauren's percent error

Computation:

Lauren's percent error = [(Number of photos predict - Number of photos actual)/(Number of photos predict)]100

Lauren's percent error = [(129 - 111)/129]100

Lauren's percent error = [(18)/129]100

Lauren's percent error = 13.95% Approx
