The only type of geometric shape that can have two side lengths of 14 ft and exactly one right angle is the isosceles right triangle. So, correct option is C.
Describe Geometric Figures?Geometric figures are shapes that are defined by their geometric properties, such as size, shape, orientation, position, and other characteristics that are inherent to their structure. These shapes can be two-dimensional or three-dimensional and can be classified into different categories based on their properties. Here are some examples of geometric figures:
Points: A point is a basic element in geometry that has no size, shape, or dimension. It is usually represented by a dot and is used to describe the position of other geometric figures.
Lines: A line is a straight path that extends infinitely in both directions. It has no thickness or width and is usually represented by a straight line with arrows at both ends.
Segments: A segment is a part of a line that has two endpoints. It can be measured by its length.
Rays: A ray is a part of a line that has one endpoint and extends infinitely in one direction.
Angles: An angle is the space between two rays that share a common endpoint, called the vertex. It is usually measured in degrees or radians.
The geometric figures that could describe how the garden might look are quadrilaterals with one right angle. Some examples of such quadrilaterals are:
Rectangle: A quadrilateral with four right angles and opposite sides equal in length.Square: A rectangle with all sides equal in length.Trapezoid: A quadrilateral with one pair of parallel sides.Rhombus: A quadrilateral with all sides equal in length. Its opposite angles are equal, but not necessarily right angles.Kite: A quadrilateral with two pairs of adjacent sides equal in length. Its diagonals intersect at right angles, but not all angles are necessarily right angles.Out of these options, the only type of geometric shape that can have two side lengths of 14 ft and exactly one right angle is the isosceles right triangle. Therefore, the answer is:
C. Isosceles right triangle.

There is a 15.74% chance that a randomly chosen employee will earn between $450 and $550.
Define probabilityThe study of random occurrences or phenomena falls under the umbrella of the mathematic discipline known as probability. It is the measure of the likelihood or chance that an event will occur, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
To find : the probability that a worker selected at random makes between $450 and $550
z = (x - μ) / б
where б is the standard deviation, μ is the mean, and x is the value we wish to normalize.
For $450, we have:
z₁ = (450 - 400) / 50 = 1
For $550, we have:
z₂ = (550 - 400) / 50 = 3
We can then use a standard normal distribution table or calculator to find the area under the standard normal curve between z₁and z₂:
P(z₁< z < z₂) = P(1 < z < 3) = 0.1574
This means that the probability that a worker selected at random makes between $450 and $550 is 15.74%.

The length and breadth of a rectangular wire are 32 cm and 12 cm. It is bent into the shape of a circle. Find the radius of the circle. (Take p = 3.14)
The perimeter of the circle formed by bending the rectangular wire will be equal to the length of the wire.
Perimeter of the circle = Length of the wire
2πr = 2(l+b) where r is the radius of the circle, l is the length of the wire, and b is the breadth of the wire.
Substituting the given values, we get:
2 x 3.14 x r = 2(32 + 12)
6.28r = 88
r = 14 cm
Therefore, the radius of the circle is 14 cm.
Answer:
14.01 cm
Step-by-step explanation:
The length of the wire is equal to the perimeter of the rectangle. So, the length of the wire is:
2 × (32 + 12) = 88 cmWhen this wire is bent into a circle, its length becomes equal to the circumference of the circle. The formula for the circumference of a circle is:
(let r = radius)
2 × π × rSo, we can write:
2 × π × r = 88Solving for r, we get:
r = 88 ÷ (2 × π) = 14.01 cmSo, the exact value of the radius of the circle formed by bending this rectangular wire is 14.01 cm.

Parvati goes to the movies with $16 in her wallet. She buys
a ticket for $6.25 and two snacks for $2.25 each. How
much money does she have left?
Select the correct expression.
OA. 16-6.25-2-2.25
OB. 16-(6.25 +2.2.25)
O C. 16-2(6.25 +2.25)
OD. 16-6.25 +2.2.25
Answer:
[tex]16-(6.25+2*2.25)[/tex]
Step-by-step explanation:
To find the amount of money she has left, you want to subtract the price of the ticket and the price of the two snacks from the amount of money she starts with.
So we want to subtract 6.25 once and subtract 2.25 twice (because she bought two snacks) from 16
16-6.25-2*2.25
Or you can also do this by adding up the monetary value of the ticket and the snacks and subtract that from the initial amount of money that Parvati has
16-(6.25+2*2.25)
(I am assuming that the "2.2.25" is supposed to say [tex]2*2.25[/tex])
What is the measure of each angle?
Answer:
a) 76
b) 26
I could only do the first two.
Suppose you have $50 in a savings account and deposit an additional $10 each week.
a) Write a recursive formula to represent the sequence.
b) Write an explicit formula to represent the sequence.
c) How much money do you have in savings after 26 weeks? Show all work.
According to the solving $310 money you have in savings after 26 weeks, we can use either the recursive or explicit formula:
Which equations are explicit?The explicit equations for L-functions are Riemann's relations between sums over an L-function's complex number zeroes and sums over prime powers for the Riemann zeta function.
According to the given information:a) Recursive formula:
Let S(n) be the amount of money in savings after n weeks. Then:
S(0) = 50 (initial amount)
S(n) = S(n-1) + 10 (deposit of $10 per week)
b) Explicit formula:
The explicit formula for this sequence is:
S(n) = 50 + 10n, where n is the number of weeks.
c) To find how much money you have in savings after 26 weeks, we can use either the recursive or explicit formula:
Using the recursive formula:
S(0) = 50 (initial amount)
S(1) = S(0) + 10 = 50 + 10 = 60
S(2) = S(1) + 10 = 60 + 10 = 70
S(3) = S(2) + 10 = 70 + 10 = 80
and so on, until:
S(26) = S(25) + 10 = 310
Therefore, after 26 weeks, you have $310 in savings.
Using the explicit formula:
S(26) = 50 + 10(26) = 50 + 260 = 310
after 26 weeks, you have $310 in savings.

The relation is not a function, but rather a circle with center at the origin and radius 2.
Does the given relation represents y as a function of x?Given the relation in the question;
x² + y² = 4.
First, lets solve for y.
x² + y² = 4
Subtract x² from both sides
x² - x² + y² = 4 - x²
y² = 4 - x²
Take the squre root of both sides
y = ±√( 4 - x² )

How many pieces of rope measuring 5/8 of a foot can be cut from a rope of 4 3/8 feet?
We can cut 6 pieces of rope measuring 5/8 of a foot from a rope of 4 3/8 feet, with some rope left over.
What is area?Area is a measurement of the size of a surface or a region in a two-dimensional space. It is expressed in square units, such as square inches (in²), square meters (m²), or square feet (ft²). To find the area of a shape, you need to multiply its length by its width, or use an appropriate formula depending on the shape. For example, the formula for the area of a rectangle is A = l × w, where A is the area, l is the length, and w is the width.
To find the number of pieces of rope measuring 5/8 of a foot that can be cut from a rope of 4 3/8 feet, we need to divide the length of the rope by the length of each piece of rope:
4 3/8 feet = 4 + 3/8 feet = 4 feet + (3/8) x 12 inches = 4 feet + 3 inches = 51 inches
Each piece of rope measures 5/8 of a foot, which is equivalent to 5/8 x 12 inches = 7.5 inches.
Now we can divide the length of the rope (in inches) by the length of each piece of rope (in inches) to find the number of pieces:
51 inches ÷ 7.5 inches ≈ 6.8
Therefore, we can cut 6 pieces of rope measuring 5/8 of a foot from a rope of 4 3/8 feet, with some rope left over.

Ten cards numbered 1 thru 10 are placed in a box. If a card is de random from the box, what is the probability of drawing a prime a 10% b 25% c 40% d 50%
Answer:
a) There are four prime numbers between 1 and 10: 2, 3, 5, and 7. So the probability of drawing a prime number is 4/10 or 2/5, which is 20% and not 10%. Therefore, option (a) is not correct.
b) As we saw in part (a), the probability of drawing a prime number is 2/5 or 40% (since 2/5 is equivalent to 0.4). Therefore, option (b) is correct.
c) The probability of drawing a prime number is 2/5 or 40%, which is not 25%. Therefore, option (c) is not correct.
d) As we saw in part (a) and (b), the probability of drawing a prime number is 2/5 or 40%, which is not 50%. Therefore, option (d) is not correct.
So, the correct answer is (b) 25%.

represents the AREA of the square. A = s²
5y+3
Answer:
Step-by-step explanation:
The expression in standard form that represents the area of the square with side length s is given by:
A = s^2
However, if you want to substitute the value of s with the expression 5y+3, then the area expression becomes:
A = (5y+3)^2
Expanding the expression, we get:
A = 25y^2 + 30y + 9
Therefore, the expression in standard form that represents the area of the square with side length 5y+3 is 25y^2 + 30y + 9.

What is parabola?Parabola is a type of curve which is defined by the quadratic equation. It has a distinct "U" shape, with the vertex of the curve being the highest or lowest point.
The point x = 9 is the vertex of the parabola, which marks the point at which the function changes from increasing to decreasing.
Since the function is a parabola, it is also a polynomial of degree 2, and it is always decreasing for points greater than the vertex, and increasing for points less than the vertex.
This means that the function is increasing on the interval (−∞, 9) and decreasing on the interval (9, ∞).

So, if we take 144 square feet, and divide by 3 hours, 144 / 3, we end up with 48, meaning Ryan can install 48 square feet of flooring every hour.
Then, simply multiply 48 by 18, 48 x 18, and you end up with 864.
Meaning, in 18 hours, Ryan can install 864 square feet of flooring.
Answer: 864 square feet.
The graph of f passes through (-4,7) and is perpendicular to the line that has
an x-intercept of 2 and a y-intercept of - 4.
The equation of the function is ?
Answer:
f(x) = - [tex]\frac{1}{2}[/tex] x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 0 ) , x- intercept and (x₂. y₂ ) = (0, - 4) , y- intercept
m = [tex]\frac{-4-0}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
to find c substitute (- 4, 7 ) into the partial equation
7 = - [tex]\frac{1}{2}[/tex] (- 4) + c = 2 + c ( subtract 2 from both sides )
5 = c
y = f(x) = - [tex]\frac{1}{2}[/tex] x + 5 ← equation of function
