Answer:

\dfrac{3}{85}

Step-by-step explanation:

It is given that a small town’s raffle has 85 entries and 3 gift baskets that three different people could win.

Total number of entries = 85

Total number of gift baskets = 3

We need to find the probability of winning a gift basket.

\text{Required probability}=\dfrac{\text{Total number of gift baskets}}{\text{Total number of entries}}

\text{required probability}=\dfrac{3}{85}

Therefore, the required probability is \dfrac{3}{85}.

Add 5/9+7/9 . Simplify the answer and write a mixed number
Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

\frac{5}{9}+\frac{7}{9}=\frac{12}{9}

Then you reducing by the fraction parts of 12/9.

\frac{12}{9}=\frac{4}{3}

And finally, you simplify by the fraction parts of 4/3.

\frac{4}{3}=1 \frac{1}{3}

Solution by Formulas

Applying the fractions formula for addiction.

\frac{(5*9)+(7*9)}{9*9}

\frac{45+63}{81}

=\frac{108}{81}

Simplifying 108/81 and the answer is

=1 \frac{1}{3}

Hope this helps!

L = building side
W = non-building side

P = 2W + L = 42 (note only one L because the other L is the building itself)

Solve for L:

L = 42 - 2W


Area = l*w
Area = (42-2W)W = 42W - 2W2

Let area be y, so y = -2W2 +42W

Note this is a parabola pointing down because the coefficient of the W2 is negative. That makes the vertex the maximum for which we are searching.

Vertex of this parabola is at W=-b/2a, if the quadratic is aW2 + bW + c = 0

a = -2
b = 42

W = -42/(2*-2) = -42/-4 = 10.5

W = 10.5
L = 42-2(10.5) = 42-21 = 21

Area = L*W = 21 * 10.5

A = 220.5 ft2
