The required answers are,

a) 675.75 \(ft^2\)

b) 9.46 gallons or we can say that 10 gallons needed.

c) $183.2

The amount of unit squares that cover a closed figure's surface is its area. Area is measured in square units like cm² and m². Area of a shape is a two dimensional quantity. The term “area” refers to the space inside the boundary or perimeter of a closed shape.

Now in the given question,

Area of Walls:

\(A(walls)=2(11*8)+2(20*8)\\A(walls)=2(88)+2(160)\\A(walls)=176+320\\A(walls)=496 ft^2\)

Area of 2 windows:

\(A(windows)=2(3*4)\\A(windows)=2*12\\A(windows)=24 ft^2\)

Area of door:

\(A(door)=2.5*6.5\\A(door)=16.25 ft^2\)

Area of walls to be painted:

\(=A(walls)-A(windows)-A(door)\\=496-24-16.25\\=455.75ft^2\)

Area of ceiling:

\(A(ceiling)=11*20\\A(ceiling)=220ft^2\)

(a) Now total area to be painted:

A(walls to be painted)+ A(ceiling)=A(total)

\(A(total)=455.75 ft^2+220ft^2\\A(total)=675.75 ft^2\)

(b) Number of Gallons:

coverage=71.41 ft^2 /gallon

675.75 ft^2/71.41 ft^/gal=gallons needed

9.46 gal= 10 gallons needed(approx)

(c) Cost of Paint:

You would need to buy 10 gallons at $18.32/gallon to have sufficient paint

cost=10 gallons x $18.32/gallon

=$183.2

Step-by-step explanation:

Grab your notebook or phone and slide it across the desk you're working on. Now turn it so it's facing sideways. Now flip it over on one of its edges so you're looking at the back side of it. All of these motions are rigid motions.

Any way of moving all the points in the plane such that

a) the relative distance between points stays the same and

b) the relative position of the points stays the same.

There are four types of rigid motions that we will consider: translation , rotation, reflection, and glide reflection.

In a translation, everything is moved by the same amount and in the same direction. Every translation has a direction and a distance. See Image-1.

A rotation fixes one point (the roto center) and everything rotates by the same amount around that point. Every rotation has a roto center and an angle. See Image-2.

A reflection fixes a mirror line in the plane and exchanges points from one side of the line with points on the other side of the mirror at the same distance from the mirror. Every reflection has a mirror line. See Image-3.

A glide reflection is a mirror reflection followed by a translation parallel to the mirror. Every glide reflection has a mirror line and translation distance. See Image-4.

Therefore,

Simply put, rigid motions are transformations that preserve the side lengths and angles in a shape. You can see any of these transformations by moving an object you may have around you right now. Grab your notebook or phone and slide it across the desk you're working on. Now turn it so it's facing sideways. Now flip it over on one of its edges so you're looking at the back side of it.

The slanted side of the triangle is always going to be 'c' because it is the longest side of the triangle.

I got these numbers because 12^2= 144 and 15^2= 225

=======================================================

Explanation:

The angles SPT and TPU marked in red are congruent. They are congruent because of the similar arc markings.

Those angles add to the other angles to form a full 360 degree circle.

Let x be the measure of angle SPT and angle TPU.

86 + 154 + 60 + x + x = 360

300 + 2x = 360

2x = 360-300

2x = 60

x = 60/2

x = 30

Each red angle is 30 degrees.

Then,

angle SPQ = (angle SPT) + (angle TPU) + (angle UPQ)

angle SPQ = (30) + (30) + (86)

angle SPQ = 146 degrees

--------------

Another approach:

Notice that angles QPR and RPS add to 154+60 = 214 degrees, which is the piece just next to angle SPQ. Subtract from 360 to get:

360 - 214 = 146 degrees

Answer:

b = 5

Step-by-step explanation:

△STR ≅ △LMN

This means the corresponding sides are equal.

SR and LN are corresponding sides.

SR and LN are equal.

The value of b is 5.

The value of SR is 43

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

△STR ≅ △LMN

This means the corresponding sides are equal.

SR = 7b + 8

LN = 11b − 12

SR and LN are corresponding sides.

SR and LN are equal.

So,

7b + 8 = 11b − 12

Subtract 7b on both sides.

8 = 11b - 7b - 12

Add 12 on both sides.

8 + 12 = 4b

20 = 4b

b = 20/4

b = 5

Now,

SR:

= 7b + 8

= 7 x 5 + 8

= 35 + 8

= 43

Thus,

The value of b is 5.

The value of SR is 43

You would need to represent the table's legs and support structure as beams, compute the plywood's load-bearing capacity, and figure out the maximum weight the table can hold before breaking in order to solve this problem.

Determining the ideal tabletop dimensions for a given surface area is another potential quadratic equations challenge.

Let's assume that the width of the table is x feet, then its length would be 2x feet. The perimeter of the table would be:

P = 2(width + length)

P = 2(x + 2x)

P = 6x

The legs would be placed 6 inches from the corners, so the length of the tabletop would be reduced by 1 foot (12 inches) on each side. Thus, the length and width of the table would be:

Length = 2x - 2(1 ft)

= 2x - 2

Width = x - 2(1 ft) = x - 2

The area of the table would be:

A = Length x Width

A = (2x - 2)(x - 2)

A = \(2x^2 - 6x + 4\)

dA/dx = 4x - 6

4x - 6 = 0

x = 1.5

Substituting x = 1.5 into the area function, we get:

A = 2\((1.5)^2\) - 6(1.5) + 4

A = 1

Therefore, the maximum area of the table is 1 square foot, and the dimensions of the tabletop should be 3 feet by 6 feet to achieve this maximum area.

The evaluated value of the function f(x) = 3e^(-x+2) - 2 for x = 4 is approximately 0.045.

To evaluate the function, we substitute x = 4 into the given equation and simplify the expression. Plugging in x = 4, we have f(4) = 3e^(-4+2) - 2. Simplifying further, we get f(4) = 3e^(-2) - 2.

Using the approximate value of e as 2.71828, we can calculate the evaluated value. Evaluating 3e^(-2) - 2, we find that f(4) is approximately equal to 0.045 when rounded to three decimal places.

Therefore, when x is 4, the function f(x) = 3e^(-x+2) - 2 evaluates to approximately 0.045.

The mercury in the thermometer was rising at the rate of 7.5°C/second.

We know that the thermometer took 18 seconds to rise from -35°C to 100°C. Let's find the average rate of temperature change over this time interval:

Average rate of temperature change = (change in temperature) / (time interval)

= (100°C - (-35°C)) / (18 seconds)

= 135°C / 18 seconds

= 7.5°C/second

This shows that the average rate of temperature change over the entire time interval was 7.5°C/second.

Since the thermometer was continuously rising in temperature, there must have been some point during this interval where the rate of temperature change was exactly 7.5°C/second. This follows from the intermediate value theorem, which states that if a function is continuous over an interval and takes on two different values at the endpoints of the interval, then it must take on every value in between at some point within the interval.

Therefore, we can conclude that somewhere along the way, the mercury in the thermometer was rising at the rate of 7.5°C/second.

Rosie is 10 years old

Step-by-step explanation:

A)

Rosie is x years old

Rosie's age (R) = x

R = x

Eva is 2 years older

Eva's age (E) = x + 2

E = x + 2

Jack is twice Rosie’s age

Jack's age (J) = 2x

J = 2x

B)

R + E + J = 42

x + (x + 2) + (2x) = 42

x + x + 2 + 2x = 42

4x + 2 = 42

4x = 42 - 2

4x = 40

\(x = \frac{40}{4} \\\\x = 10\)

There are 10 numbers less than 100 but larger than 30 that, when divided by 5 and 6, yield the same remainder. This can be determined by finding the least common multiple (LCM) of 5 and 6, which is 30.

Then, we identify the numbers in the range (30, 100) that have the same remainder when divided by 30, which is 0.

To find the numbers that satisfy the given condition, we need to consider the common multiples of 5 and 6. The LCM of 5 and 6 is 30. Any number that leaves the same remainder when divided by 5 and 6 will also leave the same remainder when divided by their LCM, which is 30.

In the given range, (30, 100), we can find the numbers that yield a remainder of 0 when divided by 30. Starting from 30 itself, we can increment by multiples of 30 to find other such numbers. The numbers that satisfy the condition are: 30, 60, 90, and so on.

To determine the total count of these numbers, we need to consider how many multiples of 30 fall within the range of (30, 100). We can divide the range width, which is 100 - 30 = 70, by the increment, which is 30. The result is (70 ÷ 30 = 2 remainder 10), meaning there are two complete sets of multiples of 30, plus an additional 10 numbers.

Therefore, there are 2 sets of numbers (30, 60, 90) and an additional 10 numbers (40, 50, 70, 80, 100) that satisfy the condition. The total count is 2 + 10 = 12.
