The dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

<h3>How to determine the dimension</h3>

For the pool, we have that;

Let the width = x feet

Length = (x+8) feet

The pool alongside the walkway gives;

Width = x + 5 + 5 = (x + 10) feet

Length = x + 8 + 5 + 5 = (x + 18) feet

Total area of the pool with walkway = 950 square feet

Note that formula for area is given as

Area = length * width = 950

Equate the length and width

(x+18)  × (x + 10) = 950

Using the  FOIL method, we have;

(x × x )+ (x × 10) + (18 × x) + (18 × 10) = 950

x² + 10x + 18x + 180 -950 = 0  

collect like terms

x² + 28x - 770 = 0

Thus, the dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

First we need the total of both children and adults that like all the flavors:

12 + 5 + 20 + 23 + 11 + 16 = 87 total people

then find the number of adults that like sweet mint: from the table 11 adults like sweet mint

to find the probability divide the number of adults who like sweet mint by the total number of people:

11 / 87 = 0.126
 the answer is A

Point A is at (-7,5) and point is at (5,-1).
olga55 [171]

Answer:

B = (3, 5)

Step-by-step explanation:

Point A is at (-7,5) and point C is at (5,-1).  Find the coordinates of point B on AC such that AB is 5 times longer than BC.  Then, B split AC in a 5:1 ratio.

rise = yC - yA = -1 - 5 = -6

run = xC - xA = 5 - (-7) = 12

c = 5/(5+1) = 5/6

B = (xA + c*run, yA + c*rise)

B = (-7 + 5/6*12, 5 + 5/6*-6)

B = (3, 5)

Lisa [10]

Answer: 5(√3-1) unit.

Step-by-step explanation:

Since, By the below diagram,

For triangle BDC,

We can write,

tan 30^{\circ}=\frac{BC}{DC}

⇒ \frac{1}{\sqrt{3}}=\frac{BC}{5\sqrt{3}}}

⇒  \sqrt{3}=\frac{5\sqrt{3}}{BC}

⇒ BC=\frac{5\sqrt{3} }{\sqrt{3} }

⇒ BC=5\text{ unit}

Now, In triangle ADC,

tan45^{\circ}=\frac{AC}{DC}

⇒ 1=\frac{AB+BC}{DC}

⇒ 1=\frac{DC}{AB+BC}

⇒ 1=\frac{5\sqrt{3}}{AB+5}

⇒ AB+5=5\sqrt{3}

⇒ AB=5\sqrt{3}-5=5(\sqrt{3}-1)\text{ unit}
