The measure of 2D is five-halves the measure of ZY, the measure of each angle of the deck.

D and R are opposite sides & G and Y are also opposite sides.

So, we have:

∠D = ∠R = 5/2 ∠Y

and

∠G = ∠Y

The sum of angles is given as:

∠D + ∠G + ∠Y + ∠R = 360

Substitute values for ∠D, ∠G, ∠R

5/2 ∠Y + 5/2 ∠Y + ∠Y + ∠Y = 360

Multiply both sides by 2/14,

∠Y = 51.43

So:

∠G , ∠Y = 51.43

∠D = 5/2 ∠Y

∠D = 128.57

Therefore, measure of angle m∠D = 128.57°, m∠G = 51.43°, m∠R = 128.57°, m∠Y = 51.43°.

A parallelogram is a two-dimensional flat shape with four angles. The internal angles on either side are equal. The transversal's angles on the same side are supplementary, which means they sum to 180 degrees. As a result, a parallelogram's internal angles add up to 360 degrees.

No se puede determinar la edad de cada hijo con la información proporcionada.

Step-by-step explanation:

Since, Ian worked 25 hours at the grocery store last week and 36 hours this week. Therefore, the percent of change is a decrease  of 44% in work efficiency.

Given that:

Last week working hour of Ian is 25 hours.

Current week working hour of Ian is 36 hours.

Now,

First, subtract to find the amount of change:

36 - 25 = 11.

Therefore, The decrease is 25.

Next, divide the amount of change by the original amount:

11 ÷ 25 = 0.44

Now, to change the decimal to a percent, multiply the number by 100:

0.44 x 100 = 44%

The answer is 16.7%.

Therefore,  the percent of change, a decrease of 44% in working efficiency.

A positive correlation indicates that: the value of one variable increases, the value of the other increases.

There are many instances in daily life where we employ related variables, such as height and weight. Ice cream sales rise in tandem with rising temperatures. Therefore, we refer to two variables as being correlated when they are connected. There are 4 different kinds. i.e., a perfect correlation, a perfect correlation, a negative correlation, and no correlation.

The supplied two variables move in the same direction when there is a positive correlation (i.e increasing together o decreasing together). So, in this case, the correlation coefficient is positive.

On solving the provided question, we can say that angle a = 113

;angle b = 57;

angle c = 57  

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the angle's sides, that converge at a center point known as the angle's vertex.

Two rays can create an angle in the plane where they are arranged. Additionally, when two planes collide, an angle is created. Dihedral angles are what they are called. An angle is a possible shape for two rays or lines with a common termination in planar geometry. The English term "angle" derives from the Latin word "angulus," which meaning "horn." The vertex is the common endpoint of the two rays, also known as the sides of the angle.

from the 3rd figure, we have -

angle a = 113 ( vertical opposite angle)

angle b = 180 - a    (Corresponding angles)

180 - 113 = 57

The probability 7C3 = 35 possible ways to place 7 identical balls into 3 identical boxes.

The number of ways to place 7 identical balls into 3 identical boxes can be calculated by using the combination formula. The formula for combinations is nCr = n! / (r! (n-r)!), where n represents the total number of items and r represents the number of items being chosen. In this case, n = 7 and r = 3, so the formula becomes 7C3 = 7! / (3! (7-3)!). This simplifies to 7C3 = 7! / (3!4!) = 35. Therefore, there are 35 possible ways to place 7 identical balls into 3 identical boxes.

In each case, the balls can be placed into one box, two boxes, or three boxes, depending on how many balls are placed in each box. If one ball is placed in each box, then the remaining four balls can be placed in any of the boxes, giving four possibilities. If two balls are placed in each box, then the remaining one ball can be placed in any of the boxes, giving three possibilities. Finally, if all seven balls are placed in one box, then there is only one possibility. When the combinations of each scenario are added together, the total number of possible ways to place 7 identical balls into 3 identical boxes is 35.

Explanation:

you need to find the common denominators. Looking at the problem, there are 3 different denominators. 8, 16, and 4. To tell the difference, here they are bolder and italicized to see the difference.

1 3/8+13/16-3/16+2/8-1/4

We can combine the common denominators, leaving us with this:

1 5/8+10/16-1/4

Then you need to make the denominators the same, and since 4 times 2 is 8, you can multiply the numerator and denominator by 2 so the denominator is 8. Then since you can divide 16 by 2 and it equals 8, and the numerator is even, you can divide the numerator and denomorator by 2 so the denominator is also 8. This ends up looking like this:

1 5/8+5/8-2/8

Then you need to combine the common denominators again, leaving you with this:

1 8/8

You can simplify that to simply “2”

(From the start you can also take the 1 and make the original operation into 11/8+13/16 etc., but for this equation it was possible to leave it out until the end and only write it as a placeholder and reminder until the very end. Then at the end I added back in.)

To sell 80% of a total of 1400 units, the salesman must sell 1120 units, and he must sell 520 units from his next shipment of 600 units.

To solve this problem, we need to find out how many units the salesman must sell in order to have sold 80% of the 1400 units in total (800 units from the first shipment and 600 units from the next shipment).

The 80% of the total number of units is calculated as:

To find out how many units from the next shipment the salesman must sell, we subtract the number of units from the first shipment (800 units) from the total number of units that need to be sold (1120 units), which results in:

Finally, we subtract the number of units the salesman has already sold from the next shipment (600 units) from the number of units he still needs to sell (320 units), which results in:

However, since the number of units sold cannot be negative, we must instead calculate the number of units the salesman must sell from the next shipment, which is:

Hence, the salesman must sell 520 units from his next shipment of 600 units.

The solutions to the quadratic equation x² - 10x + 25 = 17 are x = -√17 + 5 and x = √17 + 5.

The quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown .

To find x, we use the quadratic formula;

x = (-b±√(b² - 4ac)) / (2a)

Given the quadratic equation in the question.

x² - 10x + 25 = 17

First, we rearrange in standard form

x² - 10x + 8 = 0

Plug these values into the quadratic formula above and solve for x.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -(-10) ±√( (-10)² - 4×1×8)) / (2×1)

x = ( 10 ±√( 100 - 32 )) / 2

x = ( 10 ±2√17 ) / 2

x = 10/2 ± (2√17)/2

x = 5 ± √17

x = ±√17 + 5

x = -√17 + 5 and x = √17 + 5

The CPA selected the probability-proportional-to-size (PPS) sampling technique because it enables the selection of items in a population in proportion to the items' sizes. This technique yields a more accurate audit by precisely measuring the population of accounts receivable balances.

CPAs frequently employ the probability-proportional-to-size (PPS) sampling technique, also known as dollar-unit sampling, when examining the receivables balances of their clients. With this approach, it is possible to choose population members based on how big they are. The CPA can precisely gauge the population of accounts receivable amounts as a result, which is advantageous. A more accurate audit is made possible by the fact that the larger items in the population are more likely to be chosen than the smaller ones. Additionally, when the sample size grows, the audit's accuracy rises as well, which is another reason CPAs like to employ PPS sampling in their audits. This approach is advantageous because it ensures that the CPA is assessing the population of accounts receivable balances precisely and that the audit is carried out in a precise and trustworthy manner.

The required pressure for the given information is 55.6 N/m².

Pressure is defined as the force exerted per unit area. It can be calculated by dividing the force by the area over which it is spread. In this case, the force is 506 N and the area is 9.1 m², so the pressure can be calculated as follows:

pressure = force / area

= 506 N / 9.1 m²

= 55.6 N/m².

The unit of pressure is N/m² or Pascal (Pa). Therefore, the pressure in this case is 55.6 Pa. This means that for every square meter of area, there is a force of 55.6 N acting on it.
