1.4  is the value of r in the equation given.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. For solving equations The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

In the given equation,

10r -1.5 = 12.5

Simplifying using PEMDAS

add 1.5 on both sides

10r = 14

divide by 10 into both sides

r = 14/10 = 1.4

To rotate a triangle 180° about the origin counterclockwise, we can take each vertex of the triangle and reflect it across the origin. This will produce a new set of coordinates for each vertex that is the same distance from the origin as the original, but on the opposite side of the origin.

For example, the vertex F has coordinates (6, 3). If we reflect this point across the origin, we get the new point (-6, -3). Similarly, the vertex G has coordinates (3, 4), which become (-3, -4) when reflected across the origin, and the vertex H has coordinates (1, 7), which become (-1, -7) when reflected across the origin.

Therefore, the coordinates of each vertex of the triangle after rotating it 180° about the origin counterclockwise are as follows:

Note: When rotating a point about the origin, the direction of rotation (clockwise or counterclockwise) is important. If we had rotated the triangle 180° about the origin clockwise instead of counterclockwise, the new coordinates of each vertex would have been the same as the original, since the triangle would be reflected across the origin and end up in the same position as it started.

The volume of the liquid in the conical flask is 980 π cm³

What is a Cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the centre of base) called the apex or vertex.

The volume of a cone is given by the equation

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

Given data ,

Let the two cones be A and B

Now , the smaller cone be A

The larger cone be B

The radius of the smaller cone is r = 8 cm

The height of the smaller cone is h = 20 cm

Now , the volume of the smaller cone V = ( 1/3 ) πr²h

Substituting the values in the equation , we get

Volume of cone A = ( 1/3 ) πr²h

Volume of cone A = ( 1/3 ) π x 8 x 8 x 20

Volume of cone A = 426.67 π cm³

Now ,

The larger flask is filled with height H = 20 cm

The radius of the larger cone is R = 14 cm

The height of the larger cone is H = 15 cm

Now , the volume of the smaller cone V = ( 1/3 ) πR²H

Substituting the values in the equation , we get

Volume of cone B = ( 1/3 ) πR²H

Volume of cone B = ( 1/3 ) π x 14 x 14 x 15

Volume of cone B = 980 π cm³

Therefore , the volume of the larger cone B is 980 π cm³

Hence , The volume of the liquid in the conical flask is 980 π cm³

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Here,

Let the amount of people  receiving your email is x

The amount of people receiving your email opened it is 7%

7/100 * x = 0.07x

The amount of people receiving your email clicked a link is 2%

So,

2/100 * x = 0.02x

Therefore,

percent of those who opened the email ,  clicked a link is

AC:PC.= 3/5, as  Line l ∥ AB and passes through point M to intersect diagonal AC and leg BC at points P and N.

A trapezoid, commonly referred to as a trapezium, is a quadrilateral or a polygon with four sides. It has a set of parallel opposing sides and a set of non-parallel sides.

The bases and legs of the trapezoid are known as the parallel and non-parallel sides, respectively.

A trapezoid is a closed, four-sided, two-dimensional figure that has both a perimeter and an area.

The bases of the trapezoid are the two sides of the shape that are parallel to one another. The legs or lateral sides of a trapezoid are the non-parallel sides. The altitude is the shortest distance between two parallel sides.

According to our question-

Consider about the triangles ACB and PCN.

These triangles contain

Since angle C is the common angle and the transversal BC cuts two parallel lines PN and AB, angles ABC and PCN are congruent as equivalent angles by virtue of the reflexive property.

In light of the AA Similarity Theorem, triangles ACB and PCN are comparable.

Similar triangles have matching sides that are proportionate, thus

3/8 / 5/8= 3/5

Therefore , the height of the given square pyramid is 12 cm.

The area occupied within an object's three-dimensional bounds is referred to as its volume. The object's capacity is another name for it.

Here,

To calculate a square pyramid's volume in terms of h, use the formula h = [tex]\frac{3V}{s^{2} }[/tex]

With V = 400 and s = 10 cm, a square pyramid's height is 12 cm.

The equation for calculating the volume of a square pyramid is:

=> 1/3 [tex]s^{2}[/tex]h =V

=> h = [tex]\frac{3V}{s^{2} }[/tex]

Therefore we can rewrite the formula in terms of h you need to:

=> h = [tex]\frac{3V}{s^{2} }[/tex]

You must substitute these numbers into the following formula to determine the height of a square pyramid with volume V = 400 and side lengths s = 10 cm:

=> h = 3 * 400 / [tex]10^{2}[/tex]

=> 3* 400/100

=> 3*4

A sector is a part of a circle that is bounded by an arc and two radii. Thus the area of the lawn is Option D. 589.

A circle is a figure that is bounded by curved lines called circumference. Some parts of a circle are radius, sector, diameter, chord, circumference, arc etc.

A sector can be defined as a part of a circle which is bounded by two radii and an arc.

The area of a sector can be determined by;

Area of a sector = (θ/360) *r²

where: θ is the measure of the internal angle of the sector        

   r is the radius of the sector

In the given question, it can be observed that the area of the lawn that receives water from the sprinkler has the shape of a sector.

So that:

Answer: -6x

Step-by-step explanation:

Just subtract the coefficients:

The coefficient of 10x is 10

The coefficient of 16x is 16

now do ten minus 16 (TIP: if you don't really like negative numbers, then an easy way of subtracting 10-16 is 16-10=6, then add the negative sign to 6; -6)

10 - 16 = -6

Now put the x back: -6 = -6x

The correct answer is -6x

Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.

The additive inverse of a number is the number which when we add to the number results zero.

Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.

The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).

Suppose we have to find additive inverse of 5.

Let the additive inverse of 5 be x.

So,5+x=0

x=-5

So the additive inverse of 5 is -5.

Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

The equations that have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p are 2.3p – 10.1 = 6.49p – 4 and 230p – 1010 = 650p – 400 – p

The equation is given as

2.3p – 10.1 = 6.5p – 4 – 0.01p

Evaluate the like terms on the right-hand side

So, we have the following representation

2.3p – 10.1 = 6.49p – 4

The above equation is an equivalent equation of the given equation

Multiply through the equation by 100
