A. all angles are right angles
B. opposite sides with equal length
C. all sides with equal lenght
The characteristics a rhombus and a rectangle always have in common is opposite sides with equal length.
The right option is B. opposite sides with equal length
From the question,
We are to determine which of the given characteristics do a rhombus and a rectangle always have in common.
To determine which of the characteristics, we will list some of the characteristics of the two shapes
Characteristics of a Rhombus
All sides are of equal length Opposite sides are parallelOpposite angles are congruent Diagonals intersect perpendicularly Consecutive angles are supplementaryCharacteristics of a Rectangle
Opposite sides are congruent and parallel Diagonals bisect each other Each of the interior angles is a right angleDiagonals are congruentNow, from above,
We have that all the sides of rhombus are equal in length, which makes the opposite sides to be equal as well.
Also, among the characteristics of a rectangle is that, opposite sides are equal in length
Hence, the characteristics a rhombus and a rectangle always have in common is opposite sides with equal length. The right option is B. opposite sides with equal length

The option B is correct. A rhombus and a rectangle always have opposite sides with equal length in common. This is a defining property of all parallelograms.
In geometry, both a rhombus and a rectangle are types of parallelograms. To determine what characteristics they have in common, we must identify their properties. A rhombus has all sides of equal length, but its angles are not necessarily right angles. In contrast, a rectangle has all angles as right angles, but its sides are not necessarily of equal length. Therefore, the characteristic that both a rhombus and a rectangle always have in common is:
Opposite sides with equal length (Option B)This means that in both a rhombus and a rectangle, the opposite sides are parallel and equal in length, which is a defining property of all parallelograms.
3 pipes take 60 minutes to water the field. How much time will it take to water the field with 6 pipes? Is this direct proportion or inverse proportion and why? Full working out and equation please.
Answer:
30 minutes.
Step-by-step explanation:
The more pipes you have the less time it takes to water the field.
This is inverse proportion.
t varies as 1 / p
t = k/p
Inserting the given values:
60 = k/3
so k = 180.
and the equation of variation is
t = 180 / p.
When the number of pipes = 6 the time
= t = 180 /6
= 30 minutes.
when you start from a given set of rules and conditions and determine what must be true, you are using__ reasoning.

what relation describes the graph?
Answer:
C
Step-by-step explanation:
They are written in (x,y) coordinates. so (0,2 1/2) is the dot on the y axis located at 2 1/2 and is directly on the line as x is 0 and y is 2 1/2.
(-1/2,0) coordinate will be on the left of the origin (the centre of the graph a.k.a 0,0) as the x is negative. the y is 0 so it will be on the x axis.
Just remember, if x is negative then the dot moves to the left, if it is positive then to the right. If y is positive then it will move upwards. If it is negative then it will move downwards. Therefore, the x coordinate controls right and left, the y coordinate controls up and down. If it is 0 then it will not move and just stay on that axis.

Answer:
Basically it means to do Keep, Change, Flip. that's a better way to remember "reciprocal". keep the 5, change the ÷ to a × and flip the fraction 2/9 to a 9/2.
After doing that, you'll get the the first answer. 5/1 × 9/2 = 45/2
Answer: First option.
Step-by-step explanation:
When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.
To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.
Then, the reciprocal of the fraction [tex]\frac{2}{9}[/tex] is:
[tex]\frac{9}{2}[/tex]
Therefore, you can find the quotient of [tex]3[/tex]÷[tex]\frac{2}{9}[/tex] by multiplying [tex]\frac{5}{1}[/tex] by [tex]\frac{9}{2}[/tex]:
[tex]5[/tex]÷[tex]\frac{2}{9}=\frac{5}{1}*\frac{9}{2}=\frac{45}{2}[/tex]

[tex]2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)[/tex]
We need to solve the above expression.
First Convert Mix fraction into improper fraction
[tex]2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)\\=2(\frac{3}{5}x+ \frac{11}{4}y-\frac{1}{4}x-\frac{3}{2}y+3)[/tex]
Combining the like terms
[tex]=2(\frac{3}{5}x-\frac{1}{4}x+ \frac{11}{4}y-\frac{3}{2}y+3)[/tex]
Solving like terms
[tex]=2(\frac{3x*4-5x}{20}+ \frac{11y-3y*2}{4}+3)\\=2(\frac{12x-5x}{20}+ \frac{11y-6y}{4}+3)\\=2(\frac{7x}{20}+ \frac{5y}{4}+3)[/tex]
Multiply each term with 2
[tex]=2*\frac{7x}{20}+ 2*\frac{5y}{4}+2*3\\=\frac{7x}{10}+ \frac{5y}{2}+6[/tex]
[tex]=\frac{7x}{10}+ 2\frac{1}{2}y+6[/tex]
So, Option B is correct.

Determine the value of impulse from this graph of momentum vs time
Answer:
try 12 Newton seconds
Step-by-step explanation:
I think it's going to be 12 because if you find the slope of the first line you get 1 Newton and the slope of the second line is -1 Newton's. so that means there is a change of -2 newtons. so if you multiply -2 Newton's by the 6 seconds you -12 Newton seconds. let me know if this is correct as it's been a while since I've done this type of stuff.
Answer:
The value of impulse is 9 N-s.
Step-by-step explanation:
The momentum vs time graph shows the impulse
Impulse :
Impulse is the product of force and time.
In mathematical terms,
[tex]I= F\Delta t[/tex]
Where, F = force
t = time
According to graph,
Impulse[tex]I = F\cdot t[/tex]=total area
[tex]I=\dfrac{1}{2}\times3\times6[/tex]
[tex]I=9\ N-s[/tex]
Hence, The value of impulse is 9 N-s.

A cat and a dog have a race. The cat’s strides are 30% shorter than the dog’s but it makes 30% more strides than the dog. Which of them will win the race?
Let [tex]x[/tex] be the length of a cat's stride, and [tex]y[/tex] their stride per time unit ratio.
So, in a time unit, the cat will cover a distance of [tex]xy[/tex]
Dogs strides are 30% longer, do a dog's stride is
[tex]\dfrac{130}{100}x = \dfrac{13x}{10}[/tex]
But its stride per time unit is 30% less:
[tex]\dfrac{70}{100}y = \dfrac{7y}{10}[/tex]
So, in a unit of time, the dog will cover a distance of
[tex]\dfrac{13x}{10}\dfrac{7y}{10} = \dfrac{91}{100}xy[/tex]
So, in the same amount of time, the dog covers 91% of the distance of the cat.

If 3p-q=6 and 2p+3q=4 find q
Answer:
It is -24/11
Step-by-step explanation:
This is a system of equations. Using substitution should give the answer.
Taking the first equation, q = 3p - 6. Plug this into the second equation.
2p + 3(3p - 6) = 4. Distributing gives 2p+ 9p - 18 = 4. Subtract 4 from both sides to give: 11p - 14 = 0. p = 14/11
Plug this back into the first equation.
42/11 - q = 6
q = 42/11 - 6, which equals -24/11
Hope this helps!
Answer:
Correct Answer: Option A
Explanation
3p - q = 6 ........ 1
2p + 3q = 4 ....... 2
Multiply eqn 1 by 3
9p - 3q = 18 ........ 3
2p - 3q = 4 ......... 2
Add eqn3 and eqn2
11p = 22 => p = 22/11 = 2
Substitute for p =2 in eqn1
3p - q = 6
3x2 - q = 6 => 6 - q = 6 => -q = 6 - 6
q = 0

How do you use parallel and perpendicular lines to solve real-world problems?
Answer:
In engineering, construction, and technical fields
Step-by-step explanation:
The use of parallel lines has many wide applications
For example, the parallel lines are important in science in preventing parallax errors in measuring, say the meniscus of the water in a glass.
Another use is in construction. The use of the plumb line shows if the object being built is straight or not. The principle is that the force of the pull acts downwards. Another example is the spirit lever. This can be used by builders to check if the surface is even or not.
In engineering, the properties are important in building bridges and other high-tension structures.

Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. When a player is on level one of the game, the population of zombies is 50,000. Each time the player advances to a new level, that population grows at a rate of 5%. Answer the questions that follow to continue Gavin’s analysis.
Gavin's analysis of a game's zombie population growth involves understanding the concept of exponential growth, characterized by a fixed percentage increase over time, and the eventual transition to logistic growth as resources become limited.
Explanation:The scenario presented involves an analysis of exponential growth, which is a typical mathematical concept found within algebra and applied mathematics.
Gavin's analysis of the game app, which features a starting zombie population of 50,000 that grows at a rate of 5% per level, allows us to examine how the population changes as players advance through the levels.
Exponential growth is characterized by a constant rate of growth applied to a continuously growing base over time.
In the case of the example town mentioned, we learn that exponential growth can lead to doubling populations and that the rule of 70 is a shortcut to estimate the number of years required for a population to double at a constant growth rate.
Specifically, if the town's population doubles every 10 years, this implies a growth rate of approximately 7% per year since 70 divided by the growth rate (7) equals the doubling time (10 years).
However, such unchecked exponential growth will eventually transition to logistic growth, especially when resources become limited, thus limiting the population size to a maximum capacity, known as carrying capacity.
In biology, this logistic growth curve begins with an exponential phase, followed by a slowdown, and eventually levels off at the carrying capacity.
Final answer:
The subject of this question is Mathematics and the grade is High School. Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. Each time a player advances to a new level, the population of zombies grows at a rate of 5%.
Explanation:
The subject of this question is Mathematics and the grade is High School.
In this question, Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. When a player is on level one of the game, the population of zombies is 50,000. Each time the player advances to a new level, that population grows at a rate of 5%.
To calculate the population of zombies at each level, we can use the formula:
The population of zombies at level one: 50,000The population of zombies at level two: 50,000 x 1.05 = 52,500The population of zombies at level three: 52,500 x 1.05 = 55,125And so on...By using this exponential growth formula, Gavin can analyze the growth of the zombie population as players advance through the levels of the game.
which expression is equivalent to the radical expression shown below when it is simplified?
[tex] \sqrt{ \frac{3}{64} } [/tex]
Answer:
[tex]\sqrt{\frac{3}{64} }[/tex] in simplified form is [tex]\frac{\sqrt{3}}{8}[/tex]
Step-by-step explanation:
We need to solve the expression
[tex]\sqrt{\frac{3}{64} }[/tex]
We know that [tex]\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}[/tex]
and 64 = 8*8
Solving we get
[tex]=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}[/tex]
So [tex]\sqrt{\frac{3}{64} }[/tex] in simplified form is [tex]\frac{\sqrt{3}}{8}[/tex]
To simplify the given radical expression √3/64, first express the fraction as a power of a fraction. Apply the power rule of radicals and simplify the expression.
Explanation:To simplify the given radical expression √3/64, we first express the fraction under the radical sign as a power of a fraction. 3/64 can be written as 3/(26). Next, we can apply the power rule of radicals, which states that √(a/b) = √a/√b. Applying this rule, we can rewrite the radical expression as √3/(26). Finally, we can simplify the expression by evaluating the square root of 3 and 26. The simplified expression is √3/23 or 3/(23).

Final answer:
The solution set of the quadratic inequality x^2 - 5 < 0 is {x | -√5 < x < √5}, representing all x-values between -√5 and √5.
Explanation:
The quadratic inequality in question is x² - 5 < 0. To find the solution set, follow these steps:
Add 5 to both sides of the inequality to get x² < 5.Take the square root of both sides, keeping in mind we need to consider both the positive and negative roots, which lead to x < √5 and x > -√5.The solution set includes all x values between -√5 and √5, which can be written as {x | -√5 < x < √5}.Graphically, this represents the x-values for which the curve of y = x² is below the line y = 5.
