Answer:

491 ft²

Step-by-step explanation:

We know the area of a sector, A = Ф/360° × πr² where Ф = angle subtended by sector = angle of rotation of sprinkler = 90° and r = radius of sector = length of spray = 25 feet.

Substituting the values of the variables into the equation, we have

A = Ф/360° × πr²

A = 90°/360° × π(25 ft)²

A = 1/4 × 625π ft²

A = 1/4 × 1963.5 ft²

A = 490.9 ft²

A ≅ 491 ft² to the nearest square foot

Answer:

 X=125

Step-by-step explanation:

180-50=130-5=125

Answer:

Step-by-step explanation:

so 8^2 +10x+3 (if you times 8*3 -gives you 24)

the middle number is 10X right so then you have to guess two numbers that either add up or take away to make it a positive 10.

so example if i try 5+5 it gives me 10 but it i multiply 5 by 5 -it gives 25 therefore lets try another pair of numbers.

i chose 6 and 4 because when i add them it gives me 10 and when i multiply them, it gives me 24.

therefore im just going to:

8x^2+6x+4x+3

to factorise im going to use 2x

2x(4x+3) + 1(4x+3)

so my answer is (2x+1) and (4x+3)

Answer:

[tex]\sqrt{549}[/tex] ≈ 23.4

Step-by-step explanation:

A = bh

270 = 15b

b = 18

Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse:  a² + b² = c²

15² + 18² = c²

225 + 324 = c²

c² = 549

c = √549

Answer:

AAS Postulate.

Step-by-step explanation:

The AAS Postulate states that if 2 angles and a non-included side are congruent on both triangles, then the two triangles are equivalent.

In this case, the first Angle is: ∠B ≅ ∠D (Given, both are 90° in measurement)

For the side: Line BE ≅ line DE (Given)

∡BEA ≅ ∡DEC (Definition of Vertical Angles)

AAS Postulate is therefore used.

Answer:

The new coordinates are:

Please check the attached graph.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged

If the scale factor is between 0 and 1, it gets shrunk

If the scale factor = 1, the object and the image are congruent

Given the vertices of the triangle in the diagram

A (1, 4)

B(2, 2)

C(-2, 1)

In our case:

Rule to calculate the dilation by a scale factor 6 centered at the origin

P(x, y) → P'(6x, 6y)

Here, P'(6x, 6y) ) is the image of P(x, y).

Thus,

A (1, 4)  → A'(6(1), 6(4))  → A'(6, 24)

B(2, 2)  → B'(6(2), 6(2))  → B'(12, 12)

C(-2, 1) → C'(6(-2), 6(1))  → C'(-12, 6)

Therefore, the new coordinates are:

The solution of the inequality is h > 2.

The graph of the solution is attached below.

The given inequality is,

                          5 + h > 7

Add and subtract 5 on both side of the equation.

                      5 + h - 5 > 7 - 5

                                h > 2.

The graph of the solution is attached below.

Hence, the solution of the inequality is h > 2.

The solution to the inequality 5 + h > 7 is h > 2. Graphing the solution involves representing the range of values for h that satisfy the inequality.

Here's a step-by-step explanation:

In summary, the solution to the inequality 5 + h > 7 is h > 2. Graphing the solution involves marking an open circle at 2 on a number line and shading the region to the right, indicating all values greater than 2.

Answer:

19/2 or 9.5 or 9 1/2

Step-by-step explanation:

These are equal to 1 17/2

Answer:

a). (-0.04x² + 3x + 49)

b). 79240

Step-by-step explanation:

a). Population of the pet dogs of a two is given by the expression,

   (38 + x - 0.04x²)

   And population of the pet dogs of the rest of the towns of the county by (2x + 21).

   Where x = Number of years from year 2007

   Therefore, total population of the county = (38 + x - 0.04x²) + (2x + 21)

                                                                        = -0.04x² + (x + 2x) + (38 + 21)

                                                                        = (-0.04x² + 3x + 49)

b). Difference of years between year 2007 and 2019 = 12 years

     Therefore, predicted population in year 2019 = -0.04(12)² + 3(12) + 49

                                                                                  = 36 + 49 - 5.76

                                                                                  = 79.24

     Since, population is in thousands,

     Therefore, total population of the county = 79.24 × 1000 = 79240

≈1339.73 mm³

Answer: You are correct. It is the upper-right corner.

This diagram shows the regression line (aka line of best fit), to be closest to all of the data points. It won't go through all of the data points, but it is the next best thing by getting as close as possible.

Something like the lower right corner shows the line only going through one point and it's not really close to the majority of the other points. It's close to only one or two points, and that's about it. The lower left corner is a similar story.

The upper left corner is fairly close, but the upper points are being left out. We should shift the regression line upward to make it look like what is shown in the upper right corner. We can think of it like a balancing act.

Complete Question

Eliza reads of 1/7 of her book on Monday. On Tuesday and Wednesday combined, she reads three times as much as she reads on Monday. The expression 1/7r +3(1/7r) can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined. The variable r represents the total number of pages in the book.

Eliza's book has a total of 357 pages. How many pages does Eliza read on Monday, Tuesday, and Wednesday combined?

Answer:

204 pages

Step-by-step explanation:

From the above question, we have the variable:

The expression 1/7r +3(1/7r) can be used to determine the number of pages Eliza reads on Monday, Tuesday, and Wednesday combined.

Hence:

r = 357 pages

Hence:

1/7r +3(1/7r)

1/7 × 357 + 3(1/7 × 357)

= 51 + 3(51)

= 51 + 153

= 204 pages

Therefore, the number of pages that Eliza read on Monday, Tuesday, and Wednesday combined is 204 pages
