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:

C and D

Step-by-step explanation:

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:

66.9375

Step-by-step explanation:

from what you told me 4cm=21km

if you divide 21 by four, you get how many km is one cm. which is 5.25km

15 divided by 4 = 3.75

what we know is that 4 can go into 15 three whole times. so.. 21x3=63

now what we need to figure out is that .75

so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375

63+3.9375= 66.9375

but you might have to round this i dont know if you do or not so thats the answer im giving

Answer: im pretty sure its ”A” im not 100% sure though..

Step-by-step explanation:

Answer:

y=-4

x=-3

Step-by-step explanation:

6x+2y=-26 (equation 1)

-6x+36y=-126 (equation 2)

38y=-152

Both side divide by 38

[tex]\frac{38}{38}[/tex]y=[tex]\frac{-152}{38}[/tex]

y=-4

substitution y=-4  in(equation 1)

6x-8=-26

6x=-18

x=-3

substitution y=-4  in(equation 2)

x+24=21

x=-3

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

[tex](a)[/tex]  [tex]x - 5y =-12[/tex]  and [tex]3x + 2y =-15[/tex]

Substitute [tex]x =-3[/tex] and [tex]y = -3[/tex]  in [tex]x - 5y =-12[/tex]  and [tex]3x + 2y =-15[/tex]

[tex]x - 5y =-12[/tex]

[tex]-3 - 5*-3 = -12[/tex]

[tex]-3 + 15 = -12[/tex]

[tex]12 \ne -12[/tex]

This is not a solution

[tex](b)[/tex]  [tex]x - 5y =-12[/tex]  and [tex]3x + 2y =15[/tex]

As shown in (a), (-3,-3) is not true for [tex]x - 5y =-12[/tex]

[tex](c)[/tex]  [tex]x - 5y =12[/tex]  and [tex]3x + 2y =-15[/tex]

Substitute [tex]x =-3[/tex] and [tex]y = -3[/tex]  in [tex]x - 5y =12[/tex]  and [tex]3x + 2y =-15[/tex]

[tex]x - 5y =12[/tex]

[tex]-3 - 5(-3) = 12[/tex]

[tex]-3 + 15 = 12[/tex]

[tex]12 = 12[/tex]

[tex]3x + 2y =-15[/tex]

[tex]3(-3) + 2(-3) = -15[/tex]

[tex]-9 - 6 = -15[/tex]

[tex]-15 = -15[/tex]

Hence,

(-3,-3) is true for [tex]x - 5y =12[/tex]  and [tex]3x + 2y =-15[/tex]

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:
