What is fraction?

Suppose there is a collection of objects and a part of the collection are taken. Fraction represents that part of the object which are taken. In other words it can be said that fraction represents part of a whole collection of objects.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator of the fraction

Distance Amanda ran on Monday = [tex]1\frac{1}{6}[/tex] miles = [tex]\frac{7}{6}[/tex] miles

Distance Amanda ran on Tuesday = [tex]2\frac{1}{2}[/tex] miles = [tex]\frac{5}{2}[/tex] miles

Total Distance Amanda ran on Monday and Tuesday = [tex](\frac{7}{6} +\frac{5}{2})[/tex] miles

The measurement of ∠4 is 132° when ∠3 and ∠4 are supplementary angles.

According to the question,

We have the following information:

∠3 and ∠4 are supplementary. if the measurement of ∠3 is 2x+8 and the measurement of ∠4 is 6x+12.

We know that when two angles are supplementary then it means that the sum of the given angles is 180°.

Now, before finding the measurement of ∠4, we will have to find the value of x.

∠3+∠4 = 180°

2x+8+6x+12 = 180°

8x+20 = 180

8x = 180-20

8x = 160

x = 160/8

x = 20°

Now, putting this value of x in ∠4.

∠4 = (6x+12)°

∠4 = (6*20+12)°

∠4 = (120+12)°

∠4 = 132°

Hence, the measurement of ∠4 is 132°.

The density of drink is 1.01 g/cm³ when 25 cm³ of apple juice are mixed with 15 cm³ of fruit syrup and 280 cm³ of carbonated water to make a drink with a volume of 320 cm³.

The density of a substance demonstrates the substance's density in a particular area. Mass per unit volume is the definition of density for a material. In essence, density is an indicator of how closely together matter is arranged.

It is one of an object's special physical characteristics. Greek scientist Archimedes was the first to understand the density principle. Knowing the formula and the corresponding units will make calculating density simple. Density can be symbolized by the letter D or by the symbol.

We know that the formula for density is

D = m/V

Where,

D = Density

m = mass,

V = Volume

25 cm³ of apple juice are mixed with 15 cm³ of fruit syrup and

280 cm³ of carbonated water to make a drink with a volume of 320 cm³.

Let us find the mass of each drink mixed to make the new drink

mass = density × volume

mass of apple juice =  1.05 × 25

                                 = 26.25 g

Mass of fruit syrup = 1.4 × 15

                               = 21 g

Mass of carbonated water = 0.99 × 280

                                            = 277.2 g

Total mass of the drink = 26.25 g + 21 g + 277.2 g

                                       = 324.45 g

Volume of the given drink =  320 cm³

Density of the drink = total mass of liquids/ volume

                                 = 324.45g/320cm³

                                  = 1.01 g/cm³

Thus, the density of drink is 1.01 g/cm³ when 25 cm³ of apple juice are mixed with 15 cm³ of fruit syrup and 280 cm³ of carbonated water to make a drink with a volume of 320 cm³.

Using the properties of arithmetic sequence , we calculate

a) 100 seats in the first row (b) 40 rows are required (c) 22 more seats in each row (d) 958 seats in the last row.

The overlap of any two doubly infinite arithmetic progressions seems to be either empty or another arithmetic progression, according to the Chinese remainder theorem.

If every pair of advancements in a family of twice infinite arithmetic progressions has a non-empty intersection, then there is a number that connects all of the pairs; consequently, an infinite arithmetic progression is a member of the Helly family.

However, rather than being an unending progression in and of itself, the intersection of an infinite number of infinite arithmetic progressions might be a particular number.

We know that the AP has the total number of seats between 18 000 and 22 500.

So if we take first term as 100 common difference as 22 and 40 rows we get :

sum =  [tex]\frac{40}{2} [2\times 100+(40-1)22] = 21160[/tex]

Therefore the number of seats in the arena matches the required description.

Answer:

187 people

Step-by-step explanation:

5 to 6 is the same as 5/6. 5 is the men and 6 is the women. We know that there are 102 women so we can arrange this equation.

[tex]\frac{5}{6}[/tex]  = [tex]\frac{x}{102}[/tex]

Re-arrange the equation to find x, or the number of men in the company.

[tex]\frac{(102*5)}{6}[/tex] = x

x = 82

We have found the number of men in the company. Now add the number of men and women.

102 + 82 = 187

187 total people!

Answer: 187 employees

Step-by-step explanation:

ratio of men to women: 5:6

number women working for company: 102

to work out the number of men working for the company, you must first find out what you have to multiply 6 by to get to 102

therefore you do 102/6 which is 17

now you do 17x5 to work out how many men are working for the company which is 85

total number of employees: 102+85=187

To find the reflection.

Now, According to the question:

Let's know the Reflection over x - axis:

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Come to the solution:

F(- 2, 2) , G(- 2, - 4) and H(- 4, - 4)

Dilation: (x, y) -> (3/4 * x, 3/4 * y)

F' (3/4 × -2 , 3/4 × 2) = (-3/2 , 3/2)

G'  (3/4 × -2 , 3/4 × -4) = (-3/2 , -3)

H'  (3/4 × -4 , 3/4 × -4) = (-3 , -3)

Reflection in the x -axis of FGH are:

F" (-3/2 , -3/2)

Work Shown:

5 out of 9 are pepperoni, so 4 out of 9 are not pepperoni

(4 not pepperoni)/(9 pizzas) = (x not pepperoni)/(144 pizzas)

4/9 = x/144

4*144 = 9x

576 = 9x

9x = 576

x = 576/9

x = 64

------------------

Slightly alternative route:

(5 pepperoni)/(9 pizzas) = (y pepperoni)/(144 pizzas)

5/9 = y/144

5*144 = 9y

720 = 9y

9y = 720

y = 720/9

y = 80

Out of the next 144 pizzas, 80 are expected to be pepperoni. That means there should be 144-80 = 64 pizzas that aren't pepperoni.

Answer:

this is a rip off there at no 20 points it only 10

Step-by-step explanation:

y = -1/5x + 3 which is a line perpendicular to 5x - 3y = -2 passing through the point (-5, 2).

The two distinct lines that cross each other at a 90° angle are called perpendicular lines. Have you noticed any similarities between the walls' intersecting corners, such as the letter "L"? They are the parallel lines, which are straight lines that cross each other at the proper angle.

If two lines cross at a 90° angle, we say that they are perpendicular to one another.

We know that perpendicular lines have reciprocal and opposite sign slope, so the slope of 5x - 3y = -2 is 5 and according the y intercept form,

3y = 5x +  2b

And for a perpendicular line the slope will be -1/5

Now using the point-slope form we will find the line perpendicular to Point (-5, 2)

y − y₁ = m(x − x₁)

Put m as -1/5, y₁ as 2 and x₁ as -5, and we will get

y − 2 = -1/5(x − 5)

y - 2  = -1/5x + 1

y  = -1/5x + 1 + 2

y  = -1/5x + 3

Thus y = -1/5x + 3 which is a line perpendicular to 5x - 3y = -2 passing through the point (-5, 2).

The slope of the given line is 0.8.

From the given graph, the coordinate points are (0, 3.5) and (-4.5, 0)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.

So, slope = (y2-y1)/(x2-x1)

= (0-3.5)/(-4.5-0)
