Answer:

All the points on (x - 2)² + (y - 5)² = 100

Step-by-step explanation:

It should be the circle with its center on point (2,5) and radius is 10.

(h , k) : center of circle (2,5)    h = 2     k = 5

r: radius     r = 10

Circle: (x - h)² + (y - k)² = r²

(x - 2)² + (y - 5)² = 100

Answer:

Below.

Step-by-step explanation:

There are many .

Two are  (2+10, 5) =  (12,5) and (2,5+10) = (2, 15).

The gardeners should buy 48 white and 116 pink hydrangeas altogether

Step-by-step explanation:

The given is:

We need to find how many white and how many pink hydrangeas the gardeners should buy altogether

Assume that the number of white hydrangeas is x and the number of pink hydrangeas in the first bed

∵ The first bed has x white hydrangeas

∵ The first bed has y pink hydrangeas

∵ The total of white and pink hydrangeas in 1st bed is 45

- Equate the sum of x and y by 45

∴ x + y = 45 ⇒ (1)

∵ In the 2nd bed the number of the white hydrangeas is 2 times

   as in the 1st bed

∵ The number of the pink hydrangeas is 3 times as in the 1st bed

∵ The number of the hydrangeas in the 2nd bed is 119

- Multiply x by 2 and y by 3, then add the products and equate

  the sum by 119

∴ 2x + 3y = 119 ⇒ (2)

Now let us solve the system of equations

Multiply equation (1) by -3 to eliminate y

∵ -3x - 3y = -135 ⇒ (3)

- Add equations (2) and (3)

∴ -x = -16

- Divide both sides by -1

∴ x = 16

- Substitute the value of x in equation (1) to find y

∵ 16 + y = 45

- Subtract 16 from both sides

∴ y = 29

∵ The number of the white hydrangeas in the 1st bed is x

∵ The number of the white hydrangeas in the 2nd bed is 2x

∴ The total number of the white hydrangeas = x + 2x = 3x

∵ x = 16

∴ The total number of the white hydrangeas = 3(16) = 48

∵ The number of the pink hydrangeas in the 1st bed is y

∵ The number of the pink hydrangeas in the 2nd bed is 3y

∴ The total number of the pink hydrangeas = y + 3y = 4y

∵ y = 29

∴ The total number of the pink hydrangeas = 4(29) = 116

The gardeners should buy 48 white and 116 pink hydrangeas altogether

Answer:

C

Step-by-step explanation:

Answer:

78

Step-by-step explanation:

600 times 13%

Answer:

a) Given in attachment.

b) Quadrilateral formed is a rhombus. Because length of all the sides are equal and angle between adjacent sides is not 90°.

c) 24 unit².

Step-by-step explanation:

Let rectangle be ABCD with length 8 and width 6

And mid-points be E,F,G,H

Now, join the mid-points .

we know that angle between adjacent sides in a rectangle is 90°.

⇒ ΔFAE forms a right angle triangle with 90° at A.

By, pythagoras theorem , EF² = AF² + AE²

⇒ EF² = 3² + 4² = 25

⇒ EF = 5;

In the same way, FG = GH = HE = 5

⇒ the quadrilateral is either square or rhombus.

Now, from ΔFAE,   sin(∠AEF) = [tex]\frac{4}{5}[/tex]

(sinФ = opposite side / hypotenuse)

⇒ ∠AEF = 53°;

In similar manner;

∠DEH = 53° . Now ∠FEH = 180 - 53 - 53 = 74° (sum of angles on a straight line is 180°)

⇒ the quadrilateral is rhombus has angle between adjacent sides is 53° and not 90°.

Now, to find the area of rhombus, join EG and FH. And name the intersection point as J.

consider ΔEJF,

it is a right angled triangle at J, and also quadrilateral AFJE forms rectangle, as diagonals intersect perpendicular in a rhombus.

⇒ FJ = 3 and EJ = 4.

⇒ area of this triangle = 1/2 × base × height

                                     = 1/2 × EJ × JF = 1/2 × 3 ×4 = 6

similarly triangles FJG, GJH, HJE.

⇒ area of rhombus = 6+6+6+6 = 24.

answer: B

cost of one peppermint cookies = $ 0.6

cost of one cinnamon sugar cookies = $ 0.3

Let "p" be the cost of one peppermint cookies

Let "c" be the cost of one cinnamon sugar cookies

To find: cost of each cookie

We can frame a equation as:

120  peppermint cookies x cost of one peppermint cookies + 30  cinnamon sugar cookies x cost of one cinnamon sugar cookies = $ 81

[tex]120 \times p + 30 \times c = 81[/tex]

120p + 30c = 81  --------- eqn 1

70  peppermint cookies x cost of one peppermint cookies + 60  cinnamon sugar cookies x cost of one cinnamon sugar cookies = $ 60

[tex]70 \times p + 60 \times c = 60[/tex]

70p + 60c = 60 --------- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "p" and "c"

Multiply eqn 1 by 2

240p + 60c = 162  --- eqn 3

Subtract eqn 2 from eqn 3

240p + 60c = 162

70p + 60c = 60

(-) -------------------------

170p = 102

Substitute p = 0.6 in eqn 1

120p + 30c = 81

120(0.6) + 30c = 81

72 + 30c = 81

30c = 9

Summarizing the results:

cost of one peppermint cookies = $ 0.6

cost of one cinnamon sugar cookies = $ 0.3

Answer:

Anna is incorrect.

Step-by-step explanation:

Find lengths of diagonals SQ and OM.

1. Consider right triangle SQR. By the Pythagorean theorem,[tex]SQ^2=SR^2+RQ^2\\ \\SQ^2=14^2+7^2\\ \\SQ^2=196+49\\ \\SQ^2=245\\ \\SQ=\sqrt{245}=7\sqrt{5}\ units[/tex]

2. Consider right triangle OML. By the Pythagorean theorem,

[tex]OM^2=OL^2+LM^2\\ \\OM^2=7^2+7^2\ [\text{In square LMNO, side } OL \text{has the same length as side }LM]\\ \\OM^2=49+49\\ \\OM^2=98\\ \\OM=\sqrt{98}=7\sqrt{2}\ units[/tex]

Since [tex]7\sqrt{5}\neq 2\cdot 7\sqrt{2}=7\sqrt{8},[/tex] diagonal SQ is not two times diagonal OM. Thus, Anna is incorect.

Answer:

Anna is not correct

Step-by-step explanation:

 Part A: No, anna is not correct because first the rectangle (PQRS) its says that the length of (SR) is 14 inches and if cut in half at the diagonal a rectangle or a square would have 2 triangles so if A2 + B2 = C2 then if C = the length of the diagonal and A would = 14 in ( the length of the rectangle) and then B would = 7 inches which is the width of the rectangle. It concludes that 14 to the power of 2 + 7 to the power of 2 = 245 which its square root is 15.65 ( if rounded to the hundredth place) 

Part B: Next, is the square (LMNO) if its length and width are both 7 inches then A2 = 7 to the power of 2 and also B2 will also = 7to the power of 2 and C2 will = will be the length of the diagonal.So, all of that 7 to the power of 2 + 7 to the power of 2 = 98 and its square root is 9.89 ( if rounded to the hundredth place) so lets just say 9.9.

Then you can see that 9.9 times 2 does not equal 15.65 so Anna was wrong.  

The first link is for the first question, and the second one is to the second question I hope this helps!

Answer: [tex]S_{29}[/tex] = 2001

Step-by-step explanation:

Since the sequence is an arithmetic sequence , it means that a common difference must exist.

Let the terms in the sequence be [tex]T_{1}[/tex] , [tex]T_{2}[/tex] , [tex]T_{3}[/tex] , [tex]T_{4}[/tex] , ...

Then common difference = [tex]T_{2}[/tex] - [tex]T_{1}[/tex] = [tex]T_{3}[/tex] - [tex]T_{2}[/tex] = 8

That is , the common difference (d) = 8

The formula for calculating sum of  n terms is given by :

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a + (n-1)d ]

Where ;

n = number of terms

a = first term

d = common difference

From the question :

n = 29

a = -43

d = 8

Substituting into the formula , we have

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] [ 2{-43} + (29-1)(8) ]

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] (-86 +224)

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] ( 138)

[tex]S_{29}[/tex] = [tex]\frac{4002}{2}[/tex]

[tex]S_{29}[/tex] = 2001

Answer:

3

Step-by-step explanation:

For this question, you need to make change the denominators of the fractions to be equal, making them the same lowest common denominator.

8/9 -> 40/45

4/15 -> 12/45

Since 12 goes into 40 3 1/3 times, he can patrol that many neighborhoods in 8/9's of an hour, which is rounded to 3 because he doesn't have enough time for 4.

To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value. The answer is 10/3, which means the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour.

To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value.

Given that it takes 4/15 of an hour to patrol a single neighborhood, we can divide 8/9 by 4/15.

To divide fractions, we multiply by the reciprocal, so 8/9 ÷ 4/15 becomes 8/9 × 15/4. Multiplying across, we get (8 × 15) / (9 × 4) = 120 / 36 = 10 / 3.

Answer:

10ab + 4a + 5b + 2

= 10ab + 5b + 4a + 2

= 5b(2a+1) + 2(2a+1)

= (5b+2)(2a+1)

To find the solution to the system of equations 5x - 8y = -45 and 9x - 8y = 49, you can solve by elimination. The solution is x = 23.5 and y = 20.3125.

To find the solution to the system of equations:

5x - 8y = -45

9x - 8y = 49

Answer:

B. 3x² – 10x + 13

Step-by-step explanation:

given:

f(x) = 3x² – 8x + 5

g(x) = 2x – 8

f(x) - g(x)

= (3x² – 8x + 5) - (2x – 8)

= 3x² – 8x + 5 - 2x + 8

= 3x² – 10x + 13

Final answer:

To maintain the same weekly revenue after reducing her pot price from $24 to $16, a potter working 4 days a week must increase her daily production from 14 pots to 21 pots, which is an increase of 7 pots per day.

Explanation:

The question involves a potter who initially makes 14 pots per day and works 4 days a week, charging $24 per pot. To find out by how many pots per day she must increase her production after lowering her price to $16 per pot, to make the same amount of money, we first calculate her current weekly revenue:

After reducing the price to $16 per pot, we need to determine how many pots per day she needs to sell to maintain the same weekly revenue of $1,344:

Therefore, she needs to sell 7 more pots per day (21 pots - 14 pots) to maintain her weekly revenue.

Answer:

∠ZPB and ∠APZ are two adjacent supplementary angles

Step-by-step explanation:

we know that

Two angles are Adjacent when they have a common side and a common vertex

Two angles are supplementary if their sum is equal to 180 degrees

In this problem we have that

[tex]m\angle ZPB=90^o[/tex] ----> given problem

[tex]m\angle APZ=90^o[/tex] ----> given problem

so

[tex]m\angle ZPB+m\angle APZ=180^o[/tex]

∠ZPB and ∠APZ are supplementary angles

and

∠ZPB and ∠APZ have a common side (ZP) and a common vertex (P)

therefore

∠ZPB and ∠APZ are two adjacent supplementary angles

Answer: ∠ZPB and ∠APZ are two adjacent supplementary angles

Step-by-step explanation: Its the way the cookie crumbles.

1. Let us first find the missing interior angle.

m<C+53+61=180

m<C=66 degrees

law of sines: [tex]\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}[/tex]

a,b, and c represents the lengths of the triangles and A,B, and C represents the measures of the interior angles opposite to the sides.

For the purposes of this problem let us use a shorthand version for the law of sines.

[tex]\frac{sin(B)}{b} =\frac{sin(C)}{c}\\\frac{sin(61degrees)}{b} =\frac{sin(66degrees)}{142}\\b=142sin(61degrees)/sin(66degrees)\\[/tex]

b=134.95 meters approx.

AC is equal to length b in this case so AC=134.95 meters approx.

2. law of cosines: a²=b²+c²-2bccos(A)

Let us rearrange this formula so that we can solve for cos(C) in terms of a, b, and c (the sides lengths of the triangle).

a²=b²+c²-2bccos(A)

a²-b²-c²=-2bccos(A)

[tex]\frac{a^{2}-b^{2}-c^{2}}{-2bc}[/tex]=cos(A)

cos(A)=[tex]\frac{a^{2}-b^{2}-c^{2}}{-2bc}[/tex]

Now, because we want to find measure of angle A...

cos(A)=[tex]\frac{13.7^{2}-12.2^{2}-22.1^{2}}{-2(12.2)(22.1)}[/tex]

cos(A)=0.83 approx.

A=33.52 degrees approx.

3. Solving with law of cosines.

law of cosines: a²=b²+c²-2bccos(A)

a²=16²+18²-2(16)(18)cos(52 degrees)

a²=256+324-576cos(52 degrees)

a²=580-576cos(52 degrees)

a²=225.38 approx.

a=15.01 units approx.

Solving with law of sines.

law of sines: [tex]\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}[/tex]

For the purposes of this problem let us use a shorthand version for the law of sines.

[tex]\frac{sin(71 degrees)}{18} =\frac{sin(52 degrees)}{x}\\xsin(71 degrees)=18sin(52degrees)\\x=\frac{18sin(52degrees)}{sin(71 degrees)} \\[/tex]

x=15.00 un approx.

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, - 4) and (x₂, y₂ ) = (1, 2)

m = [tex]\frac{2+4}{1-3}[/tex] = [tex]\frac{6}{-2}[/tex] = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 2), then

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - 3x + 5 ← equation of line

Answer:

y=-3x+5

Step-by-step explanation:

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

m=(2-(-4))/(1-3)

m=(2+4)/-2

m=6/-2

m=-3

y-y1=m(x-x1)

y-(-4)=-3(x-3)

y+4=-3(x-3)

y=-3x+9-4

y=-3x+5

Answer:

[tex]0\leq 4x+8\leq 12[/tex]

Step-by-step explanation:

Compound inequality contain at least 2 or more inequality which is separated by "either" or "or". The end result has to satisfy both the inequality to be correct.

Now, creating compound inequality.

Lets assume a number "x" to create inequality.

As per given word problem: The sum of four times a number and eight.

∴[tex]4\times x + 8[/tex] = [tex]4x+8[/tex]

Next, as given the equation has to be between zero and twelve.

∴ [tex]0\leq 4x+8\leq 12[/tex]

∴ We have the inequality for word problem is [tex]0\leq 4x+8\leq 12[/tex].

The compound inequality that represents the given word problem is [tex]\( 0 < 4x + 8 < 12 \).[/tex]

To create a compound inequality for the given word problem, we need to translate the words into a mathematical expression. The problem states that "the sum of four times a number and eight is between zero and twelve." Let's break this down:

1. Identify the variable: The problem is asking about "a number," which we will represent with the variable [tex]\( x \).[/tex]

2. Translate "four times a number" into a mathematical expression: This phrase becomes  [tex]\( 4x \).[/tex]

3. Translate "the sum of four times a number and eight" into a mathematical expression: This phrase adds 8 to the previous expression, resulting in[tex]\( 4x + 8 \).[/tex]

4. Translate "is between zero and twelve" into a mathematical inequality: This phrase indicates that the expression [tex]\( 4x + 8 \)[/tex]  should be greater than zero and less than twelve. In mathematical terms, this is written as two separate inequalities:[tex]- \( 4x + 8 > 0 \)- \( 4x + 8 < 12 \)5.[/tex]  Combine the two inequalities into a compound inequality: Since we want both conditions to be true at the same time, we use the logical "and" to combine them. The compound inequality is then:[tex]\( 0 < 4x + 8 < 12 \[/tex] )This compound inequality states that the expression [tex]\( 4x + 8 \)[/tex]  should yield a value that is greater than 0 and less than 12, which accurately represents the conditions given in the word problem.
