The Smiths have a pool that is 20 feet by 35 feet. A 5 foot wide deck completely surrounds the pool. The average depth of the po

ol is 6 feet. How much surface area is covered by the proposed pool deck?

Pepsi [2]1 year ago
4 0

Answer:

550 square feet

Step-by-step explanation:

There are 4 areas where the pool deck is situated on:

Top, Left, Right, and Bottom of the pool.

So if the deck is 5 feet wide:

Top = (35 feet * 5 feet) = 175

Bottom = (35 feet * 5 feet) = 175

Left = (20 feet * 5 feet) = 100

Right = (20 feet * 5 feet) = 100

175 + 175 + 100 + 100 = 550 square feet

Uhhh-
Step2247 [10]

Step-by-step explanation:

y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = 3x - 4 as line L.

Slope of line L = 3

=> Slope of line L2 = -1/3

We have y = -1/3 x + c as our line L2 equation.

When x = 9, y = 5.

=> (5) = -1/3 * (9) + c

=> 5 = c - 3, c = 8

Hence the answer is y = -1/3 x + 8.

Suppose a and b are the solutions to the quadratic equation 2x^2-3x-6=0. Find the value of (a+2)(b+2).
KonstantinChe [14]

Answer:

(a+2)(b+2) = 4

Step-by-step explanation:

We are given the following quadratic equation:

2x^2-3x-6=0

Let a a and b be the solution of the given quadratic equation.

Solving the equation:

2x^2-3x-6=0\\\text{Using the quadratic formula}\\\\x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\\\\\text{Comparing the equation to }ax^2 + bx + c = 0\\\text{We have}\\a = 2\\b = -3\\c = -6\\x = \dfrac{3\pm \sqrt{9-4(2)(-6)}}{4} = \dfrac{3\pm \sqrt{57}}{4}\\\\a = \dfrac{3+\sqrt{57}}{4}, b = \dfrac{3-\sqrt{57}}{4}

We have to find the value of (a+2)(b+2).

Putting the values:

(a+2)(b+2)\\\\=\bigg(\dfrac{3+\sqrt{57}}{4}+2\bigg)\bigg(\dfrac{3-\sqrt{57}}{4}+2\bigg)\\\\=\bigg(\dfrac{11+\sqrt{57}}{4}\bigg)\bigg(\dfrac{11-\sqrt{57}}{4}\bigg)\\\\=\dfrac{121-57}{156} = \dfrac{64}{16} = 4

Samuel uses cubes of the same size as the small cubes to make a cuboid twice as long, three times as wide and four times as high
vodka [1.7K]

Answer:

23 more cubes

Step-by-step explanation:

If it's 2 times as long, the length is 2

If it's 3 times as wide, the width is 3

It it's 4 times as high, the height is 4

2 · 3 · 4 = 24, which is 23 more than 1

. Fill in the blank with the most accurate definition.
Zigmanuir [339]

Two distinct points are \boxed{{\text{collinear}}}. Option (C) is correct.

Further Explanation:

Given:

The options are as follows,

(A). Coplanar.

(B). Equidistant.

(C). Collinear.

(D). Complementary.

Explanation:

A point is a location on the graph or at any surface.

A line is the distance between the two points that extends to infinite in both directions.

The points that are on the same plane is known as coplanar points.

Ifdistance to the points from a particular point is same then the points are equidistant.

The points that are on the same line is known as collinear points.

Two distinct points are \boxed{{\text{collinear}}}. Option (C) is correct.

Option (A) is not correct.

Option (B) is not correct.

Option (C) is correct.

Option (D) is not correct.
