a) The category that shows a decrease in the average monthly expenditure between 2010 and 2020 is Leisure.

b) The average monthly expenditure on food was 175 euros more in 2020 than in 2010.

c) The total expenditure in 2020 is of: 1,625 euros.

The bar chart shows the average monthly expenditure in five categories, considering that:

Then a decrease happens for the category which the blue bar is greater than the gray bar, which is Leisure.

The averages on Food are given as follows:

Hence the difference is of:

325 - 150 = 175 euros.

From the gray bars, the 2020 total is given as follows:

250 + 425 + 325 + 550 + 75 = 1,625 euros.

Answer:

D

Step-by-step explanation:

The correct answer is D. The SSS Triangle Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent. In the given situation, triangle ABC and triangle DEF are congruent because all three sides of triangle ABC are congruent to the corresponding sides of triangle DEF.

Answer: -81

Step-by-step explanation: So, when finding exponents, you have to multiply the # in parentheses (in this case, -3) and multiply it by itself 4 times, so once is 3 x 1, twice is 3 x 3 = 9, three times is 9 x 3 = 27, and finally, 27 x 3 = 81. Oh, and a positive times a negative is ALWAYS negative. I hoped this explains why this is the rule for exponents.

If Sue's home is the origin and the positive direction is assumed to the right, then her position is 2 mi.

Therefore, the answer is 2mi.

Origin depends on the frame of reference, it depends on from where the observer is viewing.

From the figure, distance between home and Sue = 2 - 0 = 2mi

and the distance between Cinema and Sue = 5 - 2 = 3mi

Sue's position is 2mi right to her home and 3mi left to the Cinema. So if her home is the origin and positive direction is to the right x is +2 mi.

Answer:

Its been a minute since I've done this math

Step-by-step explanation:

This statement demonstrates the substitution property.

The substitution property states that if two expressions are equal, then we can substitute one expression for the other in any equation or inequality. In this case, "A" is an acute angle, and "m2A" is the measure of twice that angle. The statement says that if we double the measure of an acute angle, the result will be 30 degrees. Therefore, we can substitute "m2A" for 30 degrees in any equation or inequality.

The reflexive property states that any number or object is equal to itself. The symmetric property states that if a = b, then b = a. The transitive property states that if a = b and b = c, then a = c. None of these properties are demonstrated in the given statement.

The polynomial p(x) must have at least two zeros, since it has three relative extrema.

What is polynomial?

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables. x²- 4x + 7 is an illustration of a polynomial with a single indeterminate x.

Here i would think that since there are only 3 critical points given and no other information other than that those are the only critical points that p(x) would not have any real zeros.

At each of the relative extrema, the value of the function changes from increasing to decreasing or vice versa, meaning that the function crosses the x-axis at that point, which is a zero. Therefore, p(x) must have at least two zeros.

Answer:

22.50

Step-by-step explanation:

other answer is cryptic so here is a full explaination

To find the regular price of the hat, we need to determine the amount of the discount and then add that amount to the discount price.

The discount on the hat is 20% of the regular price, or 20/100 * regular price. The discount price is $18, so we can set up the equation:

discount price = regular price - (20/100 * regular price)

Substituting the known values into the equation, we get:

$18 = regular price - (20/100 * regular price)

Solving for the regular price, we find that the regular price is $22.50. This is the price of the hat before the discount.

A control group is a statistically significant subset of experiment participants who are not exposed to factors. For example, in a pharmaceutical medication research, the control group is given a placebo, which has no impact on the body. Assume you want to put a new ADHD medicine to the test.

[tex] \sf \: x = 25[/tex]

Step-by-step explanation:

Given equation,

→ (x - 7)2 = 36

Now the value of x will be,

→ 2(x - 7) = 36

→ (2 × x) - (2 × 7) = 36

→ 2x - 14 = 36

→ 2x = 36 + 14

→ 2x = 50

→ x = 50/2

→ [ x = 25 ]

Hence, the value of x is 25.

Answer:

x = 25

Step-by-step explanation:

(x-7)2 = 36

divide both sides by 2

x-7 = 18

add 7 to both sides

Answer: first choice!

sin2Theta= -4rt21/25

cos2Theta = 17/25

Step-by-step explanation:

Use Double Angle Formulas.

You can find cos2Theta immediately because one of the formulas needs only sin(theta) and that was given.

Cos2Theta =

1 - 2(sinTheta)^2

= 1 - 2(-2/5)^2

= 1 - 2(4/25)

= 1 - 8/25

= 25/25 - 8/25

= 17/25

The only answer with cos2theta=17/25 is the first choice.

Use a simple graph and Pythagorean Theorem to find cos(theta). Then you can use the Double Angle Formula for sin2theta. This would kinda be a double check if you have time. Since the first part of the solution eliminated all choices except the first choice, if you're pressed for time just do cos2theta calculation and pick the first choice.

See image for sin2theta calculation.

Answer:

Step-by-step explanation:

To find the slope of a line that passes through two points, we can use the slope formula, which is written as follows:

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

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

Given the points (-7, -2) and (-15, -14), we can substitute their coordinates into the slope formula to find the slope of the line:

slope = (-14 - (-2)) / (-15 - (-7))

= -12 / -8

= 3/2

Therefore, the slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2. In simplest form, this is equal to 1.5.

We can see two transformations.

1) ΔABC  → ΔA'B'C', it is a translation 10 units left and 2 units up.

2)  ΔA'B'C'  → ΔA''B''C'', it is a reflection across the x-axis.

The equation of the line that passes through the point (1, 6) and is perpendicular to the line x + 3y = 27 is y = 3x + 3.

What is a perpendicular line?

If two geometrical objects overlap at a right angle, they are perpendicular.  It can be defined between two planes, two lines, or two planes and another line.

Here, we have

Given

The point (1, 6) and is perpendicular to the line x + 3y = 27

The slope of the line x + 3y = 27

m = -1/3

The slope of the line perpendicular to the line x + 3y = 27

M = 3

The equation of the line:

y - 6 = 3(x - 1)

y = 3x + 3

The vehicle travels 110 feet distance in 1 second duration.

mph expresses the speed or velocity in miles per hour. Speed means rate of change of distance with respect to time.

speed = distance/time

hence, distance = speed x time

the above equation is the relationship between distance, speed and time

we will use the above equation and convert miles to feet and second to hour.

given, speed of vehicle = 75 mph

time = 1 second =1/3600 hour as 1 hour = 3600 second

distance travel by vehicle = speed x time

                                            = 75 mph x 1/3600 hour

The evaluation is 10.67 of given geometric progression.

A geometric progression is a set of elements where each succeeding element is created by multiplying the one before it by a number called the common ratio. The standard representation for a geometric progression series is a, ar, ar²,..., where an is the first term and r is the common ratio of the sequence.

The ratio between two consecutive numbers, or a number divided by the number before it in the sequence, is known as the common ratio since it is the same for all numbers or common.

The sum of a finite geometric series can be found using the formula:

[tex]a (1-r^{n}) / (1-r)}[/tex].

Where a is the first term and r is the common ratio between successive terms.

To find the ratio of successive terms by plugging into the formula

r = aₙ +1 / (aₙ)

Simplifying,

r =1/4

And the first term is;

when n=1, a = 8

Substituting all the values to the formula,

The summation of GP

Any quadrilateral can be divided into two triangles by adding a diagonal. By Euclidean geometry, the sum of the measures of internal angles equals 180°. Likewise, we can determine how short or long a side is in terms of side BD by law of sine:

AD / sin 60° = AB / sin 63° = BD / sin 57°

1.155 · AD = 1.122 · AB = 1.192 · BD

AD = 0.971 · AB = 1.032 · BD

BC / sin 57° = CD / sin 55° = BD / sin 68°

1.192 · BC = 1.221 · CD = 1.079 · BD

BC = 1.024 · CD = 0.905 · BD
