By answering the above question, we may infer that As a result, (x, y) = is the answer to the system of equation (3, 0).

A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.

The equations in the system are:

x + 2y = 3 ... (1)

x - 3y = 3 ... (2)

We may use equation (2) to solve for x in terms of y:

x = 3 + 3y

If this value of x is substituted into equation (1), the result is:

(3 + 3y) + 2y = 3

If we simplify this equation, we get:

5y = 0

Hence, y = 0. Inputting y = 0 into the equation we found for x results in:

x = 3 + 3(0) = 3

As a result, (x, y) = is the answer to the system of equations (3, 0).

Step-by-step explanation:

Answer:

x=16

Step-by-step explanation:

Mark as brainliest

Answer:

x = 16

Step-by-step explanation:

First find height (h) of the triangle:

15² = 9² + h²

h² = 15² - 9² = 144

h = √144 = 12

Now you can find the base angle Ф of the 12-9-15 triangle:

Ф = sin⁻¹(12/15) = 53.1°

Find the measure of the other base angle by knowing that the sum of the interior angles of a triangle = 180:

180 - 90 - 53.1 = 36.9°

Now you can find x:

tan(36.9) = 12/x

x = 12/tan(36.9) = 16

Atul's father is mistaken, and Atul's request for an increase in his allowance may be valid based on the information given.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

To determine whether Atul's allowance is above or below the average, we need to calculate the average allowance for all the friends, including Atul.

To do his, we add up all the amounts and divide by the total number of friends:

Average allowance = (120+180+100+50+250+200+200+220+150+100+100+150+130+200+180+100+150+100+180+150+120+150+100+150+100+120+180+200+50) / 29

Average allowance = 162.07

So, the average allowance for Atul's friends, including himself, is Rs. 162.07 per day.

Since Atul's allowance is Rs. 120 per day, we can see that his allowance is actually less than the average.

Therefore, Atul's father is mistaken, and Atul's request for an increase in his allowance may be valid based on the information given.

Answer:

How long will it take 6 people to wash all the cars?   5 hours 20 minutes

If you only have 2 hours and 40 minutes to wash all the cars how many people will you need?   12 people

Step-by-step explanation:

The important thing to realize here is that the time taken to wash x cars is inversely proportional to the number of people

That is represented mathematically as
y ∝ 1/x

The more the number of people, the less time it takes

We can write this as a proportionality equation:
y = k/x

where k is referred to as the constant of proportionality

We have the information: 4 people take 8 hours.

Plugging these two values into the equation

4 = k/8

k = 4 x 8 = 32 hours

So it takes 1 person 32 hours to wash all the cars

If there were 6 people instead
6 = 32/h where h is the time taken for 6 people to wash 30 cars

h = 32/6 = 16/3 hours = 5 1/3 hours
= 5 hours and 20 minutes

2 hours and 40 minutes = 2 40/60 hours = 2 2/3 hours

Converting to improper fraction
2 2/3 = (2 x 3 + 2)/3 = 8/3 hours

Plugging this value of x into the equation gives

y = 32/(8/3)

32 ÷ 8/3 is computed by flipping the fraction and multiplying

32 ÷ 8/3 = 32 x 3/8 = 12 people

The area of the compound figure is 41 square meters.

We can subdivide the compound figure into smaller shapes and add the areas of each to determine its area.

The figure can first be divided into two rectangles:

The first rectangle has a surface area of 18 m2 with measurements of 2 m by 9 m.

The second rectangle is 3 m by 7 m in size, which equals a surface area of 21 m2.

Next, we can calculate the two triangles' areas:

The area of the first triangle is 1/2 x 2 m x 2 m, or 2 m2, because its base is 2 m and its height is 2 m.

The area of the second triangle is 1/2 x 3 m x 2 m = 3 m2, with a base of 3 m and a height of 2 m.

The overlap between the two rectangles can then be subtracted:

The overlap measures 2 m by 3 m, making it a rectangle whose size is 2 m by 3 m, or 6 m2.

We sum the areas of the two rectangles, the two triangles, then subtract the overlap between the rectangles to determine the total area of the compound figure:

(18 m2 + 21 m2) + (2 m2 + 3 m2) - 6 m2 = total area

Area total: 41 m2.

Hence, the compound's area is 41 square metres.

We may calculate the distance from Carlos and the tree as [tex]D = 781.23[/tex] ft using trigonometric relationships.

Many functions in trigonometry offer excellent illustrations of how calculus may be used in practical situations. By the way, basic trigonometry primarily deals with the algebraic features of circular functions, therefore basic calculus is not always simpler than basic trigonometry. On the other hand, calculus is fundamentally non-algebraic in nature.

The mnemonic SOHCAHTOA makes it simple for us to recall the three primary trigonometric ratios.

Then one of the cathetus of the triangle is equal to:

[tex]275ft - 6ft = 269ft[/tex]

That cathetus is the opposite cathetus to the angle of 19° (the elevation angle). And the adjacent cathetus is the distance between Carlos and the tree.

Then we can use the relation:

Where:

[tex]a=19^{0}[/tex]

opposite cathetus [tex]=269ft[/tex]

adjacent cathetus [tex]=D[/tex]

Replacing that, we get

[tex]tan(19^{0} ) = 269ft/D[/tex]

Solving for D, we get:

[tex]D = 269ft/tan(19^{0} ) = 781.2ft[/tex]

So we conclude that Carlos is at [tex]781.23[/tex] ft of the tree.

The number that was added to complete the square is (7/2)²

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given quadratic equation is x²+7x+27=0

Add and subtract (7/2)² = 49/4

x² + 7x + 27

= ( x² + 7x + 49/4) - 49/4 + 27=0

= (x + 7/2)² - 59/4

Now we can rewrite the original equation as:

(x + 7/2)² - 59/4 = 0

Adding 59/4 to both sides, we get:

(x + 7/2)² = 59/4

Taking the square root of both sides, we get:

x + 7/2 = ±√59/2

Solving for x, we get:

x = -7/2 ±√59/2

The total area of the exercise room is 160 square feet.

The number of square yards equivalent to this total area is 17. 78 square yards.

Since the rubber flooring is sold in whole square yards, Juan must purchase exactly 18 square yards.

To find the area of the exercise room, you should divide it into two different rectangles and then add up their areas.

Rectangle 1 length = 16 ft

Rectangle 1 width = ( 13 - 6 ) = 7 ft

Rectangle 2 length = ( 16 - 8 ) = 8 ft

Rectangle 2 width = 6 ft

The area is therefore :

= ( 16 x 7 ) + ( 8 x 6 )

= 160 square feet

1 square yard is 9 square foot so 160 square foot is:

= 160 / 9

Answer:

Candice had 2 cans left over.

Answer:

To use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse, we need to find the length of the longest side (also known as the hypotenuse) by squaring each side, adding the results, and taking the square root of the sum.

So,

63^2 = 3969

58^2 = 3364

30^2 = 900

Now, we add 3969 and 3364 to get 7333, and take the square root to get approximately 85.62.

Since 63, 58, and 30 are the lengths of the sides of the triangle, we can compare the length of the longest side (85.62) to the sum of the other two sides (63 + 58 = 121) to determine if the triangle is right, acute, or obtuse.

85.62^2 = 7326.23

121^2 = 14641

Since 7326.23 is less than 14641, the triangle is acute.

If two bakers can make 30 loaves in 1 hour, then we can use proportionality to find how many hours it would take for 3, 5, 6, and 15 bakers to make 30 loaves.

Let h be the number of hours needed for a given number of bakers to make 30 loaves. Then we have:

2 bakers can make 30 loaves in 1 hour, so 1 baker can make 15 loaves in 1 hour.

Therefore:

3 bakers can make 45 loaves in h hours, so 45/3 = 15 loaves can be made in 1 hour. Thus, 3 bakers can make 30 loaves in 2 hours.

5 bakers can make 75 loaves in h hours, so 75/5 = 15 loaves can be made in 1 hour. Thus, 5 bakers can make 30 loaves in 2 hours.

6 bakers can make 90 loaves in h hours, so 90/6 = 15 loaves can be made in 1 hour. Thus, 6 bakers can make 30 loaves in 2 hours.

15 bakers can make 225 loaves in h hours, so 225/15 = 15 loaves can be made in 1 hour. Thus, 15 bakers can make 30 loaves in 2 hours.

Therefore, regardless of the number of bakers, it would take 2 hours to make 30 loaves of bread.

The percent decrease in the amount of land that Patty owns now is approximately 15.00%. Destiny's time at yesterday's race was 187 minutes.

To find Destiny's time at yesterday's race, we can first calculate the time reduction as a percentage of her previous time, and then subtract that reduction from her previous time.

The time reduction is 15% of 220 minutes -

0.15 x 220 = 33

So, she took 33 minutes less at yesterday's race.

Her time at yesterday's race is -

220 - 33 = 187 minutes

Therefore, time value is obtained as 187 minutes.

The percent decrease in the amount of land that Patty owns can be calculated by finding the difference between her old and new land sizes, dividing that by her old land size, and then multiplying by 100 to convert to a percentage.

The difference between her old and new land sizes is -

2,220 - 1,887 = 333

Dividing that by her old land size and multiplying by 100, we get -

The correct answer is: domain: all real numbers, range: all real numbers greater than or equal to -5.

We can see that the function is a polynomial of degree 4, which means it is defined for all real numbers. Also, as x^4 is always non-negative, the minimum value of the function occurs when x=0, and it is f(0) = -4. Therefore, the range of the function is all real numbers greater than or equal to -4. However, since the function is increasing as we move away from 0, the range is actually all real numbers greater than or equal to the minimum value of -4 plus the vertical shift of -1, which is -5.
