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]

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.

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.

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.

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).

[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]

Answer:

Step-by-step explanation:

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:

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

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.

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:

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.

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
