Answer:

32

Step-by-step explanation:

Since l and m are parallel, the value of 2x is equal to 64.

64/2 = 32

A quadrilateral with at least one pair of parallel sides is called, in American and Canadian English, a trapezoid. In British and other forms of English, a (North American) trapezoid is called a trapezium. The transposition of these two terms was a result of an error in Charles Hutton's mathematical dictionary.

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. As opposed to the particular examples below, a scalene trapezoid is a trapezoid without equal sides.

The Greek mathematician Euclid identified five different quadrilateral shapes, of which four had two sets of parallel sides (the square, rectangle, rhombus, and rhomboid in English) and one did not (a trapezia, meaning "a table," which comes from "four" and means "a foot; end, boundary, edge").

In his commentary on the first book of Euclid's Elements, Proclus (412–485) developed two varieties of trapezia: one pair of parallel sides, or a trapezium (v), divided into isosceles (equal legs), and scalene (unequal) Similar to how cuboid and rhomboid both mean "resembles," trapezia with no parallel sides is a trapezoid, trapezoeidé, or literally "trapezium-like."

English followed Proclus's arrangement until the late 18th century, when a prominent mathematical lexicon produced by Charles Hutton in 1795 endorsed a transposition of the terms without providing an explanation. Although this error was fixed in British English around 1875, it remained in American English till the present..

For the given mapping diagram, we have that: C. Yes (one y-value for each x-value) it represent a function.

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for uniquely mapping an input variable to an output variable.

A domain can be defined as the set of all real numbers for which a particular function is defined and these include the following: {1, 2, 3, 4}.

In conclusion, we can reasonably infer and logically deduce that this mapping diagram represent a function because it has the different input values (x-values) for different output values (y-values).

Step-by-step explanation:

x = ml of the 60% solution

y = ml of the 45% solution

x + y = 600

and therefore

x = 600 - y

0.6x + 0.45y = 0.5×600

we use the above identity in this equation :

0.6(600 - y) + 0.45y = 300

360 - 0.6y + 0.45y = 300

60 - 0.15y = 0

60 = 0.15y

y = 400 ml

x = 600 - y = 600 - 400 = 200 ml

The equation of line is =1/2 x+1/2 .

A line equation is a straightforward mathematical formula that uses the slope, x-intercept, and y-intercept of the line to describe the relationship between the points on the line.

The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, often known as the y-intercept, and m is the gradient.

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The slope is the ratio of the y-to-x change.

y=mx+b

According to graph, points are (-1,0) and (1,1)

Hence we get –m+b=0 and m+b=1

On solving m = ½ and b = ½

The equation of line is =1/2 x+1/2 .

The inequality expression given as 2 - |6 + 12x| > -28 has a solution of -3 < x < 2

From the question, the inequality is given as

2-|6+12x|>-28

Rewrite properly as

2 - |6 + 12x| > -28

Subtract 2 from both sides

- |6 + 12x| > -30

Divide both sides by -1

|6 + 12x| < 30

Remove the absolute bracket

So, we have the following representation

-30 < 6 + 12x < 30

Add -6 to all sides of the inequality

So, we have

-36 < 12x < 24

Multiply through by 1/12

So, we have

-3 < x < 2

Hence, the solution to the expression is -3 < x < 2

Given that,

In the picture there is a straight line which has a point where the 2 lines intersect.

The angles are 90° and 30°.

We have to find the angle a.

A straight angle in geometry is an angle with a vertex point that is at 180 degrees. In essence, it creates a straight line with sides that face away from the vertex. "Flat angles" is another name for it.

So, we get,

90°+30°+a=180°

a=180°-90°-30°

a=180°-120°

a=60°

When the weights (in grams) of the contents of several small bottles are 4, 2, 5, 4, 5, 2 and 6, the sample variance is D. 2.33.

It should be noted that in Mathematics, the variance simply means the average squared deviation of the mean.

From the information, the weights of the contents of several small bottles are 4, 2, 5, 4, 5, 2 and 6. Therefore, the sample variance will be illustrated thus:

N = number =7

Sum of the numbers = 28

Mean = 28 / 7 = 4

Sample variance will be:

= (4 - 4)² + (2 - 4)² + (5 -4)² + (4 - 4)² +(5 - 4)² +(2 -4)² + (6 - 5)²

= 14 / 6

She'd done the entire equation wrong

3 x 10^8 would be 300000000 when instead 10 should be to the power of 11 and 3 should be 5.049

Step-by-step explanation:

To rewrite something in scientific notation you have to group the numbers that aren't zero (5049) and convert it into a decimal (5.049)

(Decimals for scientific notations will ALWAYS have one number in the 1st digit, no matter what)

Then we see what we have to multiply our decimal to make it into our original number. We count the numbers in the decimal and the rest of our zeros (8+3=11)

5.049 x 10^11 = 504900000000

Based on the numbers to be divided of 1,060 ÷ 33 to get a quotient, the mixed number in the simplest form is 32¹/₂ .

Finding the quotient of two numbers means that one of the numbers would have to divide the other number.

The quotient in this case is:

= 1,060 ÷ 33

= 32.1212

To convert this to mixed number, divide the decimal portion by the relevant power of 10:
= 32 + 1212/10,000

= 32 + 4/32

= 32 + 1/8

= 32¹/₂

The  system of equations that could be used to determine the price of each pound of raspberries and the price of each pound of grapes is:  44 x + 43 y = 217 , 45x + 18y = 144 .  Each pound of peaches cost $2 and each pound of grapes cost $3

x = price of each pound of peaches

y = price of each pound of grapes.

Given that yesterday,  he sold 44 pounds of peaches and 43 pounds of grapes for a total revenue of $217

So 44 x + 43 y = 217 be equation 1.

Also given that today he sold 45 pounds of peaches and 18 pounds of grapes for a total revenue of $144.

So 45x + 18y = 144 equation 2.

Multiplying equation 1 with 18 gives us,

792x +774y = 3906

Multiplying equation 2 with 43 gives us,  

1935x+774y = 6192

Solving these,

792x +774y = 3906

1935x+774y = 6192

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

-1143 x=- 2286

x = 2286/ 1143

x = 2

Plug this value of x in equation 1 and solve for y, to get,

44 x + 43 y = 217

44 (2) + 43 y = 217

43 y = 217 − 88

43 y =129

Answer:

x = 17

Step-by-step explanation:

Mean of a set of data values = Sum of the data values ÷ number of data values

Here we have data:
18,23,x,22, and 20

Sum = 18 + 23 + x + 22 + 20 = 83 + x

Number of data points = 5

Mean = (83 + x) / 5 = 20 (given)

Multiplying both sides by 5 gives
83 + x = 20 x 5
83 + x = 100

Subtract 83 from both sides to give
x = 100 -83 = 17

x = 17

Answer:

Step-by-step explanation:

if 20 is the mean of 18,23,x,22, and 20 find the value of x​

(18 + 23 + x + 22 + 20) : 5 = 20

18 + 23 + x + 22 + 20 = 20 * 5

What is Percentage ?

A Percentage is a figure or ratio that is stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

The total amount paid in tax from Cary's last year earning is £9640
Total earning last year = €34 500

Tax on earnings :
First €3500 = 0%
€3500 to €10 500 = 25%
Earnings above €10 500 = 35%
Therefore, tax paid on €34 500 :

Tax percentage × amount earned

First €10 500 earned = (25% × 10,500) = 2625

Excess above €10 500 = (34500 - 10500) = 24000

25% × 24000 = 6000

Therefore, the total tax amount = €(2625 + 6000) = €8625
