Answer:

9 - 24x

Step-by-step explanation:

When using the distributive property, the number outside the parentheses (12) is "distributed" to each of the values inside the parentheses. In other words, 12 will be multiplied by 3/4 and 2x:

12(3/4 - 2x)

12(3/4) - 12(2x) <----- so now we successfully got rid of the parenthesis. Next, simplify

12(3/4) = 9

12(2x) = 24x

9 - 24x <----this is the final answer since it can't be simplified further

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

So, we have:

100(2.3p – 10.1 = 6.5p – 4 – 0.01p)

Evaluate

230p – 1010 = 650p – 400 – p

The above equation is also an equivalent equation of the given equation

Hence, the equations with the same solution are represented above

Therefore, percentage of those who opened the email ,  clicked a link is  28.57%

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

=> 0.02x/0.07x * 100

=> 2/7*100 = 28.57%

a) The Volume of space that is not occupied is; 13.80 in³

b) The length, are and volume have distinct final units.

c) The Volume of the composite shape is the sum of the Volume of Cone, Volume of Cylinder and  Volume of Hemisphere

a) Tennis ball is usually considered to be a sphere. The formula for volume of sphere is;

V = ⁴/₃πr³

where r is radius.

Since diameter = 2.6 inches, then radius; r = 2.6/2 = 1.3 inches

Thus;

Volume of each tennis ball;

V = ⁴/₃π(1.3)³

For the three tennis balls;

V₃ = 3(⁴/₃π(1.3)³)

V₃ = 8.788π

Volume of the cylindrical container = πr²h

h is height = 3(2.6) = 7.8 inches

V_cyl = π(1.3² * 7.8)

V_cyl = 13.182π

Volume of space not occupied = 13.182π - 8.788π

Volume of space not occupied = 13.80 in³

b) For length, the unit will be singular

For Area, the unit will be squared

Answer:

q=82

Step-by-step explanation:

The line is equal to 180 degrees, and we have three angles and two have numbers, so this will be easy.

Add 58+40 to get 98, now subtract 98 from 180.

180-98=82

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.

89.086 milliliters of juice will be in a glass with 7 ice cubes.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Equation of line: y = -29 202x + 293.5.

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

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

Step-by-step explanation:

as you wrote correctly, proportional relationships are in the form

y = mx

that means the line has to go through the origin (0, 0). otherwise it is in the form

y = mx + b

which is still linear but not proportional.

1a.

the rate of change is between 2 points A and B

(Yb - Ya)/(b - a)

in our case e.g. (4, 5.52) and (8, 11.04)

(11.04 - 5.52)/(8 - 4) = 5.52 / 4 = 1.38

when we use other points we get the same result. we see e.g. that when we double x (pounds), then also y (cost) is doubled.

the rate of change is 1.38.

this is also called the slope of the line.

b.

as mentioned in a., when we multiply x by a factor, then y is multiplied by the same factor. it also means that the function contains (0, 0) : for 0 pounds we pay $0.

c.

y = 1.38x

2a.

the slope is (as it is the same as the rate of change) the ratio of (y coordinate change / x coordinate change) when going from one point on the line to another.

we try to find points with integer coordinates to do that.

I see e.g. (3, 4) and (6, 8).

x changes by +3 (from 3 to 6).

y changes by +4 (from 4 to 8).

so, the slope is +4/+3 = 4/3.

b.

the simplest indicator is that the line goes through the origin (0, 0), which it does.

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:

Area of the lawn = (300/360)*22/7 * 15²
