What is a rectangle?

A rectangle is a quadrilateral with four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.

Given that the height of the poster is  2 5/8 feet.

The wide of the poster is 1 3/4 feet.

Now convert the numbers 1 3/4 feet, 2 5/8 feet mixed fraction to improper fraction:

2 5/8 feet = [(2×8) + 5]/8 = 21/8 feet

1 3/4 feet = [(1×4) + 3]/4 = 7/4 feet

The area of a rectangle space is the product of length and breadth of the rectangle shape.

The area of the poster is

(21/8) × (7/4)

Now multiply the denominators of both fractions and numerators of both fraction:

(21  × 7)/(8×4)

= 147/32

= [tex]4\frac{19}{32}[/tex] square feet

5 x 4 = 20

By solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, using the  information given, the equation can be formed as:

21w - 65 = 40

Now, solve for the subject w to get the value of w as follows:

21w - 65 = 40

21w = 40 + 65

21w = 105

w = 105/21

w = 5

Therefore, by solving an equation, we know that the value of w or the number of dogs Tina must wash to earn a profit of $400 is 5.

Answer:

1st answer option

Step-by-step explanation:

the 45° side angles make this an isoceles triangle (both legs are equally long).

therefore, x = y.

Pythagoras gives us

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle), and a and b being the legs.

so, we have

(5 × sqrt(2))² = x² + y² (remember, x = y)

(5 × sqrt(2))² = x² + x²

25 × 2 = 2x²

25 = x²

x = 5

because of x = y

y = 5

Answer:

Step-by-step explanation:

$1.25 is the cost per ticket

Jermaine bought 25 tickets in total

Spent a total of $43.75

y = total cost

x = number of ride tickets

1.25 ( 25 ) = 31.25

31.25 is the total money spent on ONLY tickets.

To find the cost of admission...

43.75 - 31.25 = 12.50

The cost of admission is $12.50

Equation: 1.25x + 12.5 = y

The cost of the tasks to surround the figures with a fence, equivalent to   perimeter of the fence and an extra percentage are as follows;

1. $143

2. $143.75

3. $147.84

4. $224.64

The perimeter of a figure is the length of the line that surrounds the plane area covered by the figure.

1. The perimeter of the fence = 2 ft +  4 ft + 2 ft + 4 ft + 2 ft + 4 ft + (4 ft - 2 ft)  = 20 ft

The perimeter needed = 110/100 × 20 ft = 22 ft

The cost of 4 feet of fence = $26

Cost per feet of fence = $26/4 = $6.5/ft

Cost of the task = 22 feet × $6.5/ft = $143

2. The perimeter of the fence = 3 ft + 3 ft + 2 ft + 3 ft + 1 ft + 2 ft + 1 ft + 2 ft + 3 ft = 20 ft

The perimeter of the fence needed = 115/100 × 20 ft = 23 ft

Cost of 4 feet = $25

Cost per ft = $25/4 = $6.25

Cost of the fencing = 23 ft × $6.25/ft = $143.75

3. The perimeter of the fence = 5 ft +  3 ft + (6 ft - 5 ft) + 2 ft +  6 ft + 2 ft + 3 ft = 22 ft

The fence needed = 120/100 × 22 ft = 26.4 ft

The cost of 5 ft of fencing = $28

The cost per feet = $28/5 ft = $5.6/ft

The cost of the fencing = 26.4 ft × $5.6/ft = $147.84

Cost of the Task = $147.84

4. The perimeter of the fence = 8 ft + 6 ft + (8 ft - 6 ft) + (8 ft - 6 ft) + 6 ft + 8 ft = 32 ft

The fencing needed = 104/100 × 32 ft = 33.28 ft

The cost for 4 feet = $27

The cost per feet = $27/4 ft = $6.75/ft

The cost of the task = 33.28 ft × $6.75/ft = $224.64

Answer: 2/1

Step-by-step explanation:

You can decide this by looking at the rise over the run.

The correct place to the decimal is after 4 digits, that is 4431.5

Decimals are the numbers, having two parts, a whole number part and a fractional part separated by a point that point is called the decimal. For example, 7.5 is a decimal number.

Given that, Mary says the digits in the quotient of 381.109÷0.86 are 44315.

but she doesn't know where to place the decimal point.

The division is 381.109/0.86

Placing the decimals in numerator and removing from denominator,

Since, in the denominator the decimal is two digits before, so multiply numerator and denominator by 100,

38110.9/86

According to rule, put the decimal point in the answer at the same place it is at in the dividend,

38110.9/86 = 4431.5

Hence, she should put decimal before digit 5.

Triangle ABC has been translated 4 units to the right into triangle DEF. Then, the coordinates of point E is (6, -2).

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that, triangle ABC has been translated 4 units to the right into Triangle DEF.

From the given coordinate plane A(-8, -2), B(2, -2) and (-4, -9)

When the shape is moved towards the right by k units, then replace x with x + k.

Now,

A(-8, -2) → D(-8+4, -2)=D(-4, -2)

B (2, -2) → E(2+4, -2)=E(6, -2)

C (-4, -9) → F(-4+4, -9)=F(0, -9)

The required expected number of women on the committee is 1/2 or 0.5.

The expected number of women on the committee can be found by calculating the probability that a woman is selected for the committee and then multiplying that probability by the number of people on the committee.

There are a total of 6 + 2 = 8 people in the club, and the committee has 2 people.

Given the committee is selected randomly, the probability that a particular person is selected for the committee is 2/8 = 1/4.

There are 2 women in the club, so the probability that a woman is selected for the committee is 2/8 = 1/4.

The expected number of women on the committee is the probability that a woman is selected for the committee multiplied by the number of people on the committee, which is (1/4) * 2 = 1/2.

Thus, the expected number of women on the committee is 1/2 or 0.5.

Answer:

  y = -3(x +4)(x -1)/((x +3)(x -6))

Step-by-step explanation:

You want a rational function with vertical asymptotes at -3, 6; x-intercepts at -4, 1; and a horizontal asymptote at y = -3.

A rational function will have vertical asymptotes at the denominator zeros. Vertical asymptotes at -3 and 6 will be had if the denominator has factors (x +3) and (x -6).

A rational function will have x-intercept at the numerator zeros. X-intercepts at -4 and 1 will be had if the numerator has factors (x +4) and (x -1).

A horizontal asymptote will be found at the y-value that is the (constant) ratio of the highest-degree terms of the numerator and denominator. Here, we can achieve that by multiplying the factors mentioned above by the desired constant (-3).

The equation is ...

  [tex]\boxed{y=-3\dfrac{(x+3)(x-6)}{(x+4)(x-1)}}[/tex]

__

Additional comment

A "hole" will be found where a numerator and denominator factor cancel. For example, a hole at x=7 could be achieved by making the function have an additional numerator factor of (x -7) and an additional denominator factor of (x -7).

Effectively, the horizontal asymptote is the quotient of the numerator and denominator (excluding the "remainder"). If that quotient is a linear (or other) function, the graph will asymptotically approach that function as the magnitude of x gets large. A linear function gives a "slant aymptote."

The magnitude of each part, after dividing, will be equivalent to 27.9.

Given is to divide 418.50 between 15.

We have to divide 418.50 between 15. If we have to divide 418.50 into 15 equal parts, then we can write -

15x = 418.50

x = 418.50/15

x = 27.9

(A)  The required inequality is,  -40°F  <  x  <  140°F.

(C) The gas has freezing point of -40°F, that means below that temperature the gas will freeze.

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

(A) Let the liquid range is from -40°F to 140°F.

Let x be the range.

So, the required inequality is,

-40°F  <  x  <  140°F

(B) The graph of inequality is attached below.

(C) Since the gas has freezing point of -40°F, that means below that temperature the gas will freeze.

(-49°F < 40°F)
