Answer:
Answer is [tex]\sqrt{13}-\sqrt{11}[/tex]
Step-by-step explanation:
We need to divide
[tex]\frac{2}{\sqrt{13}+\sqrt{11}}[/tex]
For solving this, we need to multiply and divide the given term with the conjugate of [tex]{\sqrt{13}+\sqrt{11}[/tex]
The conjugate is: [tex]{\sqrt{13}-\sqrt{11}[/tex]
Solving
[tex]=\frac{2}{\sqrt{13}+\sqrt{11}} *\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}} \\=\frac{2(\sqrt{13}-\sqrt{11})}{(\sqrt{13}+\sqrt{11})(\sqrt{13}-\sqrt{11})}\\We\,\, know\,\, that\,\, (a+b)(a-b) = a^2-b^2\\=\frac{2(\sqrt{13}-\sqrt{11})}{(\sqrt{13})^2-(\sqrt{11})^2}\\=\frac{2(\sqrt{13}-\sqrt{11})}{13-11}\\=\frac{2(\sqrt{13}-\sqrt{11})}{2}\\=\sqrt{13}-\sqrt{11}[/tex]
So answer is [tex]\sqrt{13}-\sqrt{11}[/tex]

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.
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.

–15a2b2 + 20a2b2 – 6ab + 4ab – 7
Answer:
[tex]15a^2b^2-20a^2b+6ab^2-4ab+7[/tex]
Step-by-step explanation:
The sum of two polynomials is
[tex]10a^2b^2-8a^2b+6ab^2-4ab+2[/tex]
First addend is
[tex]-5a^2b^2+12a^2b-5[/tex]
Second addend x.
Hence,
[tex]x+(-5a^2b^2+12a^2b-5)=10a^2b^2-8a^2b+6ab^2-4ab+2\\ \\x=10a^2b^2-8a^2b+6ab^2-4ab+2-(-5a^2b^2+12a^2b-5)=\\ \\=10a^2b^2-8a^2b+6ab^2-4ab+2+5a^2b^2-12a^2b+5=\\ \\=(10a^2b^2+5a^2b^2)+(-8a^2b-12a^2b)+6ab^2-4ab+(2+5)=\\ \\=15a^2b^2-20a^2b+6ab^2-4ab+7[/tex]
Answer: The correct option is (A) [tex]15a^2b^2-20a^2b+6ab^2-4ab+7.[/tex]
Step-by-step explanation: Given that the sum of two polynomials is [tex](10a^2b^2-8a^2b+6ab^2-4ab+2)[/tex] and one addend is [tex](-5a^2b^2+12a^2b-5).[/tex]
We are to find the other addend.
Let P(x) be the other addend.
Then, according to the given information, we must have
[tex]-5a^2b^2+12a^2b-5+P(x)=10a^2b^2-8a^2b+6ab^2-4ab+2\\\\\Rightarrow P(x)=(10a^2b^2-8a^2b+6ab^2-4ab+2)-(-5a^2b^2+12a^2b-5)\\\\\Rightarrow P(x)=10a^2b^2-8a^2b+6ab^2-4ab+2+5a^2b^2-12a^2b+5\\\\\Rightarrow P(x)=15a^2b^2-20a^2b+6ab^2-4ab+7.[/tex]
Thus, the other addend is [tex]15a^2b^2-20a^2b+6ab^2-4ab+7.[/tex]
Option (A) is CORRECT.
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.
What is the solution set of the quadratic inequality x2- 5<0?
O {xl-55x55
{x- 155x55)
{xl -55x5 15)
{x1 - 15 sx5/5)
Answer:
{[tex]x| -\sqrt{5} <x <\sqrt{5}[/tex]}
Step-by-step explanation:
We must solve the following inequality
[tex]x^2- 5<0[/tex]
factor the expression
[tex](x-\sqrt{5})(x+\sqrt{5})<0[/tex]
Case 1
[tex](x-\sqrt{5}) < 0[/tex] → [tex]x < \sqrt{5}[/tex]
[tex](x+\sqrt{5}) >0[/tex] → [tex]x > -\sqrt{5}[/tex]
{[tex]x| -\sqrt{5} <x <\sqrt{5}[/tex]}
Case 2
[tex](x-\sqrt{5}) > 0[/tex] → [tex]x > \sqrt{5}[/tex]
[tex](x+\sqrt{5}) <0[/tex] → [tex]x < -\sqrt{5}[/tex]
Without solution
The set solution is {[tex]x| -\sqrt{5} <x <\sqrt{5}[/tex]}
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.
Which expression gives you the distance between the points (5,1)and(9,-6)
Answer:
[tex]D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]
Step-by-step explanation:
Here we are supposed to find the distance between the two coordinates in a plane. The coordinates given to us are
(5,1) and (9,-6)
We can find the distance using distance formula. The distance formula is given as
[tex]D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]
Where
[tex](x_{2},y_{2}) ; (x_{1},y_{1})[/tex]
are the two coordinates
Hence
[tex]x_{2} = 9 ; y_{2}= -6\\x_{1}=5; y_{1}=1[/tex]
Substituting these values in the distance formula we get
[tex]D=\sqrt{(9-5)^{2} +(-6-1)^{2}}\\D=\sqrt{(4)^{2} +(-7)^{2}}\\D=\sqrt{16+49}\\D=\sqrt{65}\\[/tex]
Hence the Distance is [tex]D=\sqrt{65}\\[/tex]

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.

The point-slope form of a lone has a slope of -w and passes through point (-5,2) is shown below.
y+2=-2(x-5)
What is the equation in slope intercept form?
Answer:
y = -2x + 8Step-by-step explanation:
The point-slope form of an equationo f a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
We have
[tex]y+2=-2(x-5)\\\\y-(-2)=-2(x-5)[/tex]
Therefore we have
the slope: m = -2
the point: (5, -2) not (-5, 2)!!!
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
Convert:
[tex]y+2=-2(x-5)[/tex] use the distributive property a(b + c) = ab + ac
[tex]y+2=-2x+10[/tex] subtract 2 from both sides
[tex]y=-2x+8[/tex]

[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).

= (9)(2) x [tex]10^{10+2}[/tex]
=18 x [tex]10^{12}[/tex]
= 1.8 x [tex]10^{13}[/tex]
Answer:
(9x10^2)(2x10^10)
= 1.9 x 10^13 (In scientific notation)
Step-by-step explanation:
Expression to be simplified is given as:
(9x10^2)(2x10^10)
= 9x10^2x2x10^10
= 9x2x10^2x10^10
The base here in the expression is same so the power will add up:

= 1.8 x 10^12
Using Scientific notation on the expression, we know that the decimal point must after the first digit so that the number let us say x is such that x > 0 and x < 10. To move decimal one place back, we will multiply it with 10^1:
18 x 10^12
= 1.8 x 10 x 10^12
= 1.8 x 10^(1+12)
= 1.8 x 10^13
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

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

which of these characteristics do a rhombus and a rectangle always have in common?
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
Learn more here: https://brainly.com/question/16979502
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.

Which equation represents the line that passes through ( -8, 11) and ( 4, 7/2)?
A y= -5/8x+ 6
B y= -5/8x+ 16
C y= -15/2x- 49
D y= -15/2x+ 71
Answer:
A
Step-by-step explanation:
Recall the general equation for a straight line is
y = mx + b
where m is the gradient and b is the y-intercept
given 2 points whose coordinates are (x1, y1) and (x2, y2), m can be found with the following formula:
m = [tex]\frac{y1-y2}{x1-x2}[/tex]
in this case, x1 = -8, y1 = 11, x2 = 4, y2=7/2
applying these values to the formula for m will give
m = -(5/8)
We can see immediately that the only 2 possible answers are A or B.
If we substitute this back into the general equation, we get:
y = -(5/8)x + b
In order to find the value for b, we substitute any one of the 2 given points back into this equation. Lets choose (-8,11)
11 = -(5/8) (-8) + b
11 = -(5/8) (-8) + b
11 = 5 + b
b = 6
hence A is the answer.

[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

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]
