The price per foot of the 2-yard rope is $6.36.
To find the price per foot of the 2-yard rope, we need to first convert the length to feet. Since there are 3 feet in a yard, a 2-yard rope is equal to 6 feet.
Next, we divide the total cost of the rope ($22.86) by the length of the rope in feet (6 feet) to get the price per foot:
$22.86 ÷ 6 = $3.81 per yard
To convert this to the price per foot, we divide $3.81 by 3 (since there are 3 feet in a yard):
$3.81 ÷ 3 = $1.27 per foot
Therefore, the price per foot of the 2-yard rope is $1.27 x 5 = $6.36.

Which statements about this system of equations are true? Check all that apply
2 x minus 7 y = negative 13. Negative 2 x + 11 y = 1.
The x-variable will be eliminated when adding the system of equations.
The y-variable will be eliminated when adding the system of equations.
The sum of the system of equations is 4 y = negative 12.
x = 17
y = negative 3
There are infinitely many solutions to the system of equations.
As a result, (x, y) = is the answer to a set of equations. (-17, -3). There aren't an endless number of answers because there is a single one.
What sort of equation would that be?The meaning of an equation in algebra is a mathematical assertion that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are split by the 'equal' symbol.
The statements that are true about this system of equations are:
The x-variable will be eliminated when adding the system of equations.
There are infinitely many solutions to the system of equations.
To eliminate the x-variable, we can add the two equations as follows:
(2x - 7y) + (-2x + 11y) = -13 + 1
Simplifying the left-hand side and the right-hand side gives:
4y = -12
Dividing both sides by 4 yields:
y = -3
Substituting y = -3 into either of the original equations gives:
2x - 7(-3) = -13
Simplifying this equation yields:
2x + 21 = -13
Subtracting 21 from both sides yields:
2x = -34
Dividing both sides by 2 yields:
x = -17
Therefore, the solution to the system of equations is (x, y) = (-17, -3). Since there is a unique solution, there are not infinitely many solutions.
The statement "The sum of the system of equations is 4y = -12" is false since the sum of the equations does not simplify to that expression.
The statement "x = 17" is false since the correct solution is x = -17.
The statement "The y-variable will be eliminated when adding the system of equations" is false since adding the equations only eliminated the x-variable.

15. Anna has $2.00 in change, including 5 quarters. What is the maximum number of dimes she can have? A 2 C 7 B 5 D 9
Answer:
To solve the problem, we need to first determine the value of the quarters Anna has. Since there are 5 quarters, we have:
5 quarters = 5 x $0.25 = $1.25
Thus, Anna has $2.00 - $1.25 = $0.75 left. We can find the maximum number of dimes she can have by dividing this amount by the value of a dime, which is $0.10. Therefore:
$0.75 ÷ $0.10 = 7.5
Since Anna cannot have a fraction of a dime, we round down to the nearest whole number to get a maximum of 7 dimes. Therefore, the answer is option B, 5.
The surface area of the right triangular prism is 376.8 cm²
What is the value of x? Show your work.
In response to the stated question, we may state that As a result, the prism value of x is around 6.432 cm.
what is prism?A prism is a polyhedron with either an n-sided polygonal basis, a second base that is a shifted copy of the original base, and n extra faces (essentially all parallelograms), with two connecting the corresponding sides of the base. Any cross sections those are parallel to the base are translations of it. A prism is a three separate, solid, three-dimensional object with two faces. It has the same merge, flat sides, and similar bases. Faces of a prism are parallelograms or rectangles with out any bases. A prism is a refracting item that is homogeneous, solid, and transparent, contained by planes that are obliquely oriented to one another. A typical prism has two triangular faces and parallel square faces. They are made of either glass or metal.
Two congruent triangles and three rectangular faces make up the right triangular prism.
L is the length of the rectangular faces.
W is the width of the rectangular faces.
H is the height of the rectangular faces and the prism.
B is the triangle's base.
x is the height of the triangles.
SA = 2B + PH
B = 1/2 * base * height
B = 1/2 * 13 cm * x = 6.5x cm²
P = 13 cm + 5 cm + x = 18 cm + x
SA = 2B + PH
376.8 cm² = 2(6.5x cm²) + (18 cm + x)(12 cm)
376.8 cm² = 13x cm² + (18 cm)(12 cm) + 12x cm²
376.8 cm² = 25x cm² + 216 cm²
25x cm² = 376.8 cm² - 216 cm²
25x cm² = 160.8 cm²

. if an m-by-n matrix a multiplies an n-dimensional vector x, how many separate multiplications are involved? what if a multiplies an n-by-p matrix b?
If a multiplies an n x p matrix b then the total number of multiplications involved is m x p. And is given by Dimensional vector.
For explanation, There are two separate cases to consider when multiplying an m-by-n matrix and an n-dimensional vector, or an m-by-n matrix and an n-by-p matrix.
When an m-by-n matrix, A, multiplies an n-dimensional vector, x, the number of separate multiplications involved is m. This is because in order to compute the dot product of A and x, each row of A needs to be multiplied by the vector x, resulting in m separate multiplications.
On the other hand, when A multiplies an n-by-p matrix, B, the number of separate multiplications involved is m x p. This is because in order to multiply A and B, each row of A must be multiplied by each column of B, resulting in m x p separate multiplications.
Therefore, the number of separate multiplications involved when multiplying an m-by-n matrix and an n-dimensional vector is m, and the number of separate multiplications involved when multiplying an m x n matrix and an n x p matrix is m x p.

a mechanic sells a brand of automobile tire that has a life expectancy that is normally distributed, with a mean life of 24,000 miles and a standard deviation of 2700 miles. he wants to give a guarantee for free replacement of tires that don't wear well. how should he word his guarantee if he is willing to replace approximately 10% of the tires?
To word his guarantee for free replacement of tires, the mechanic needs to determine the minimum life expectancy that the tires must meet in order to replace approximately 10% of them.
Since the life expectancy of the tires is normally distributed, we can use the standard normal distribution and the z-score formula to determine the minimum life expectancy that corresponds to a probability of 10%:
z = (x - μ) / σ
where z is the z-score, x is the minimum life expectancy, μ is the mean life expectancy of 24,000 miles, and σ is the standard deviation of 2700 miles.
Solving for x, we get:
x = zσ + μ
Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to a probability of 10%, which is approximately -1.28. Plugging this into the formula, we get:
x = (-1.28) * 2700 + 24000
x ≈ 20,856 miles
Therefore, the mechanic should guarantee free replacement of tires that wear out before reaching a mileage of approximately 20,856 miles, in order to replace approximately 10% of the tires.

the diameter of a gazebo is 15 ft. what is its circumference? round the answer to one decimal place:
The circumference of a gazebo is 47.1 ft
To calculate the circumference, you can use the formula C=2πr. This formula states that the circumference of a circle is equal to two times the constant π (approximated as 6.28) multiplied by the radius of the circle. The radius of a circle is equal to half of the diameter, so in this case the radius would be 7.5 ft (half of 15 ft).
Therefore, to calculate the circumference of a gazebo with a diameter of 15 ft, you can use the formula C=2πr. Plugging in the radius of 7.5 ft, the equation would become C=2π(7.5) which results in a circumference of 47.12 ft. To round this answer to one decimal place, the final answer is 47.1 ft

A cone has a radius of 3 inches and a slant height of 12 inches.
What is the exact surface area of a similar cone whose radius is 9 inches?
We can use the fact that the ratio of the corresponding lengths in two similar shapes is equal to the ratio of their corresponding surface areas. Since we are looking for the surface area of a similar cone with radius 9 inches, we need to find the ratio of the surface area of that cone to the surface area of the original cone with radius 3 inches.
The surface area of a cone is given by:
surface area = πr(r + l)
where r is the radius and l is the slant height.
For the original cone with radius 3 inches and slant height 12 inches, we have:
surface area of original cone = π(3)(3 + 12) = 45π
For the similar cone with radius 9 inches, we can find the slant height using the fact that the slant height and radius are proportional in similar cones. Specifically, the ratio of the slant heights is equal to the ratio of the radii. Therefore:
slant height of similar cone = (9/3)(12) = 36 inches
Using this slant height and the radius of 9 inches, we can find the surface area of the similar cone:
surface area of similar cone = π(9)(9 + 36) = 405π
Finally, we can find the ratio of the surface areas:
ratio of surface areas = surface area of similar cone / surface area of original cone
= (405π) / (45π)
= 9
Therefore, the surface area of the similar cone is 9 times the surface area of the original cone. The exact surface area of the similar cone is 9 times the surface area of the original cone, or:
9 × 45π = 405π square inches

Gerald had some green and yellow beads. The number of green beads was 1/3 the number of yellow beads. He gave each of his friends 2 green beads and 3 yellow beads. He then had 42 green beads and 270 yellow beads left.
a. How many friends did he give the beads to?
b. What was the total number of beads he had at first?
Answer:
Step-by-step explanation:
Let's use algebra to solve this problem.
Let's start by assigning variables to the unknown quantities. Let G be the initial number of green beads and Y be the initial number of yellow beads.
We know that the number of green beads is 1/3 the number of yellow beads:
G = (1/3)Y
After giving away some beads, he had 42 green beads and 270 yellow beads left. So we can set up two equations using this information:
G - 2f = 42
Y - 3f = 270
where f is the number of friends he gave the beads to.
Now we can substitute G = (1/3)Y into the first equation:
(1/3)Y - 2f = 42
Multiplying both sides by 3, we get:
Y - 6f = 126
Now we have two equations that we can solve simultaneously:
Y - 3f = 270
Y - 6f = 126
Subtracting the first equation from the second, we get:
3f = 144
So f = 48. He gave the beads to 48 friends.
To find the total number of beads he had at first, we can use the equation G = (1/3)Y:
G + Y = (4/3)Y = (4/3)(270) = 360
So he had a total of 360 beads at first.

What is parallelogram?Parallelogram is type of quadrilateral with two pairs of parallel sides.
The opposite sides of parallelogram are congruent in length.
The opposite angles of parallelogram are congruent in measure.
The adjacent angles of parallelogram are supplementary (add up to 180 degrees).
The area of parallelogram can be calculated by multiplying the length of its base by its height.
Since ABCD is parallelogram, then opposite angles are congruent. Therefore, we have:
∠ABD = ∠ABC = 5M° (opposite angles in a parallelogram)
∠ABD = ∠CBD (alternate interior angles formed by transversal BD)
∠CBD = ∠BCD = 3M+20° (opposite angles in a parallelogram)
Thus, we have:
5M° = ∠ABD = ∠CBD = 3M+20°
Solving for M, we get:
5M° - 3M - 20° = 0

if she picks another 250 balls at random, how many red balls should she expect
Answer:
Step-by-step explanation:
250
Select the true statements. Select the two correct answers. A. 1 . 01 < 0 . 99 1 . 01 < 0 . 99 B. 4 . 5 = 4 . 50 4 . 5 = 4 . 50 C. 3 . 5 < 3 . 39 3 . 5 < 3 . 39 D. 1 . 51 > 1 . 15 1 . 51 > 1 . 15 E. 2 . 09 = 2 . 9
The true statements are:
B. 4.5 = 4.50 (both sides are equal to 4.5, with the same number of significant figures)
D. 1.51 > 1.15 (1.51 is greater than 1.15)
What is system of inequalities ?
A system of inequalities is a set of two or more inequalities with one or more variables. The solution to a system of inequalities is the set of all possible values of the variables that satisfy all the inequalities in the system simultaneously. In other words, it is the intersection of the solution sets of each individual inequality in the system.
According to the question:
The two correct statements are B and D.
B is true because trailing zeros after a decimal point do not change the value of a number, so 4.5 is equal to 4.50.
D is true because 1.51 is greater than 1.15, as the digits to the right of the decimal point represent fractions of a whole number, so 0.51 is greater than 0.15.
A is false because 1.01 is greater than 0.99.
C is false because 3.5 is greater than 3.39.
E is false because 2.09 is not equal to 2.9.

Each hemisphere has three basic wind systems. The first, at 30( latitude north and south,
is known as the (3).
There, air sinks, warms, and moves toward the
equator from northeast to southwest in the northern hemisphere and from southeast to
northwest in the southern hemisphere. When the air reaches the equator, it rises, then moves
back toward 30( to start the cycle again. These winds from both hemispheres converge at the
equator. They are forced upward, creating an area of (4)
This area
near the equator is called the (5).
The second wind system, called the (6)
flows between 300 and

This is one of the questions..
If y is directly proportional with x and y = 36 when x = 30, what is the value of y when x = 25?
THANK YOU!! <3
The value of y when x = 25 is 30
What are direct variations ?
One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.
given y is directly proportional to x then the equation connecting them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 36 when x = 30
So, 36=k(30)
=> k = 36/30 = 1.2
equation of proportionality:
y=1.2x
When x = 25 then
y=1.2(25) = 30
The value of y when x = 25 is 30
